[@hermanturnip3984]

My son and I started on this hobby just over a month ago. We fly our small beginner RTF planes each weekend at a local park. We've learned quite a bit from this channel and will be upgrading to BNF planes this month. Thanks for imparting wisdom to those just starting out. Greatly appreciated!

I watched this vid when it first came out now I just found my box of RC stuff and about to test fly my first build in years... You two were a good team.

[@JoshuaBardwell]

It sounds like it should be k/v. Thousand (k) rpms per volt.

[@mathewthompson8022]

Joshua Bardwell it is and ft got it wrong

[@RajendraBhattRajDa]

come on how many joshes are out there ??

[@donaldasayers]

K in this case stands for a mathematical "constant" there are two constants that define an electrical machine ( I am not going to say either motor or generator because they are the same thing.) KV is is the voltage constant and is a measure of how many volts you get/need for a given rpm, not thousands of rpm, just rpm. KM is the motor constant and is a measure of the torque per square root (given power loss). See Wiki on "motor constants".

[@donaldasayers]

@@mathewthompson8022 No

[@josephbargo5024]

Typically k denotes constant in scientific terminology, like rate constant for example. I think it’s a German word that it comes from.

[@lesliewoodmobile]

Exultant episodes for beginners guy's. Its good to see you doing something for beginners. Without the new guys there would be no future. For me your FPV episodes have been really intuitive and have help me no end. This is a massive thumbsup from us in the UK. Keep up the good work lads. Looking forward to the next upp load. And its great to see you guys going from strength to strength.

[@roaldkvaaleskibsrud1154]

I've always thought that rc planes looks so complicated to build, but after this series I want to build my own plane without help from KZbin!!!

[@hobie1dog]

Highly informative, thanks again. I just went to the Hobby shop today and started looking qt a Radian glider

[@BOKI797]

Josh & Josh; Great job explaining everything on Power systems ! Thanks for the Great Video !

[@fatenhappy1]

Been doing model flying aircraft since before and way back prior to gas powered ... I'm even talking multi strand rubber band stuff power gliders etc ... Even so, got to say I love the way you explain the basics, bouncing 'stuff' off each other .. great stuff and very entertaining !

[@peterellison2220]

Amazing series, this is where I learned everything rc

[@reeop23]

Josh and Josh rock. Thanks for the great intro to RC!

[@stranga4365]

You guys make the best how to series. A heads up though if you want to know. kV=kilo-volts, the capital "V" makes the difference. and they can't use C for constant because in physics C=speed of light

[@Snecho]

I wish you guys mentioned the effects on motor power when comparing 3S or 4S batteries for example, not just ESC requirements. Overall, I am pretty new to electrics and there is still some very good pointers here.

[@zimmy1958]

great job guys keep them coming us old timers may pick up something also ;) and we just like to watch the videos happy flying

[@b94cast]

Good info - but really - hat guy doesn't need to act dumb, he isn't. Act as a peer and add more to the discussion. Sorry - love your shows, just struck me as trying too hard and went the wrong way . Keep up the great work! :)

[@lankyjames88]

This annoys me too, when I first started watching flite test, I thought it was cool to have a newbie join in, hoping that he would learn and progress (along with any newbie watching the videos would) but acting dumb when we know he isn't is just odd. Josh Scott adds some good humour and he doesn't need to play dumb to get the laughs and be entertaining. I also say - let him fly more!

[@Pastorkarlman]

I actually see the logic in it. Josh is asking the questions that a newbie might ask and appears not to be learning anything because there are always new folks getting into the hobby. In this video he does push it a bit, but I find it amusing and simple answer that new folks might ask do get asked and therefore answered.

Excellent instructional videos. Well thought out and executed. Congratulations and thank you so much.

[@ABikerLife]

I don't see the link for the calculator mentioned in the video.

[@vistastang]

Look here "plane.ardupilot.com/wiki/ecalc-motor-and-prop-efficiency-guide/". It gives some good information to get started. The link is towards the top "PropCalc" to the actual calculator. It appears you have to pay $1 to gain full access. Good luck.

[@hankus253]

Did you post the link to the calculator mentioned?

[@ibillwilson]

I don't think they've posted it yet, but I'm pretty sure they meant ecalc.ch ... another choice that's somewhat easier to use is webocalc (just google it).

[@ChadKapper]

We always post additional reference info and valuable links in the article on our site. The link under the KZbin video will take you there.

[@hankus253]

Then why didn't Josh say to look there instead of saying "below".

[@tylerdigregorioaubin722]

Multi rotor beginner series please!

[@electronautomatic1258]

Will the position of the motor matter? For example a central motor on the front of the plane vs the back of the plane. Or as long as you have the plane parlance’s well the motor position doesn’t matter? Really want to make an F-22 with a pusher right on the back.

[@carmaticfrua5739]

13:36 i believe that should have said 'prop pitch' instead of 'prop diameter'

[@ncessnapilot]

I'm buying a twin engine ARF Otter from VQ Warbirds/NEXA. Can you do a video on choosing electronics for twin engines?

[@mikethered14]

how do you pick out the motor for the plane you want to fly? is it just a guessing game or what do you want to have in mind besides the weight of the aircraft. how do you yourself pick out the motor for your aircraft?

[@brettcoyle2399]

So do u buy the motor first or the esc?? @FliteTest so if I have a motor that requires 35amp I need a esc that does 40 right?? Then how do u determine what size and kind of battery to use with esc and motor?? Thanks

[@ibillwilson]

Hey guys, you linked episode 5. (Good job, btw.)

[@jaysrcadventures6337]

Hey guys I'm getting into the hobby. I have an original super cub. I need to put a new motor and esc. The original one is trashed. What would be a good starting point. I have to buy new electronics even servos. The manule dose not say anything about upgrading to brushless?

[@stranga4365]

but if the correct ESC is sold out or the one a few steps up is the same price or a few dollars more will it be ok to get say a 40amp for a 20amp motor incase you want to upgrade later?

[@brettcoyle2399]

I've never flown but in a month with taxes I'm gonna get back into RC hobby but this time gonna be planes, used to race rc cars 15 yrs ago but no planes I really want the EDF f16 Thunderbirds BNF and i was gonna get the spektrum dx8 transmitter cause from reviews of the f16 people say it's decent for beginners and I love fighter jets thanks for sharing all your knowledge if I decide not to get f16 edf I'll get the carbon cub S for sure

[@vijayganesh9072]

Hey hi I am a huge fan of your video I have some doubts Why does my lipo battery (lemon 2200mah,11.1volt,3s,30c) spark continuously while i try to connect to my esc (30a (deans connecter)) Maybe is it because of friction I am actually making a plane And I am using the battery mentioned above and the 30a esc and 2 servos and a 2200kv brushless motor And do u have any idea of the total flight time

[@zafstore]

Very good! You educated me so much. Thank you, guys!

[@bradschak]

I was given a small 3 channel balsa model with a Flight Test Radial 2280kv motor. It did not include a battery with it. Can you recommend one?

[@mikielmarvin8333]

How am I supposed to know what propeller to use on my plane ? Because I want to build one...

[@brettcoyle2399]

Depending on what speed and conditions u wanna fly in also depending on size and weight of your plane as well

[@carypotts3592]

Hey guys....nice channel, keep up the great work....Question for you are there any transmitters for rc planes that works more like a joystick?

[@dave1135]

I have a APC 10x7 prop on my gas tiger moth, been using it for 7 years with no problem. Thus, all my planes run APC props. :-)

Do have have the list of all part to match up how much voltage needs and how much amp needs so not to easy burn out. I am just a beginner nobs. And how to connect every each wires goes. Thx

[@brettcoyle2399]

So when building your own planes how do we know what size of motor, prop, esc etc.....?? @FliteTest

[@NIKFLICK707]

does the amount of motor thrust should be more than plane's weight???

[@yelectric1893]

Nikhil's World Of Every Thing depends, what kind of plane?

[@treeseatmyplanes]

What does the "class" of the motor mean? I've seen a lot of scratch builds that say the plane needs a 400 class motor, or maybe a 300 class.

[@Hello_there_obi]

Im building a slow flying hercules style high-wing. Im targeting 1.5-1.8kg for total weight. Looking to get just under 1:1 thrust to weight ration maybe 0.9-0.8:1 Looking at two wing mounted motors rated at 900g thrust each and 9X5 propellers. Are the props and motors right? Im also not sure whether to use a 2200mAh battery or a 5000mAh battery

[@Atvstevie1]

@FliteTest if i run 2 - 40 amp EDF motors will i need a 80 amp ESC? or technically 96 amp esc? can i also run individual ESC's for each motor and pair the ESCs wth my receiver ? i run spektrum

[@Pastorkarlman]

Hey Josh squared. You guys are now selling the EMAX motors with your power packs for the scratch build and speed build kits. Do you have a video or information on reversing the shaft in these motors? The e-flite series of motor has the shaft extending out the bell housing end of the motor. The EMAX motors are opposite and have the shaft extending out of the static end that must be fastened to the firewall. That makes it hard to use the shaft and spinners designed to affix to the shaft. I have built a kit as your awesome build videos explain using the bolt on screw shaft, but am looking to use the 4mm shaft that is integral to the motor. Any help would be appreciated.

[@PSDAust]

Great Video..thanks K also is a prefix for thousands..

[@soulis1000]

What about 3 or 4 blade props? Im thinking about building a p51 mustang and offcourse i want a 4 blade prop on it for the right look.

[@FieldSketch1]

Great job guys!

[@furonwarrior]

Is an ESC sort of like a power supplier for the motor?

[@dubik3e]

I think that at 13:35 there should be "prop pitch" instead "prop diameter".

[@jboynerf3458]

Where can I get all these materials, but in smaller versions? Is there size differences?

[@aval1998]

@FliteTest But what I want to a multi-engine plane? What factors change? Do I need to get a bigger battery to feed two motors instead of one?

[@AnimilesYT]

7:53 I'm probably not the first to say this, but: It is RPM per volt by the 1000s. Where does the K come from? It most likely comes from "Kilo". But unlike the usual "Kilo volts", this "Kilo" doesn't say anything about the volts. It says something about the RPM. A Kilo is 1000, and in this case 1000 RPM. A 1300 Kv motor spins at 1300 Kilo RPM per Volt. Aka, 1300000 RPM/V I didn't consult a source to fact-check this. I only used logic to figure this out myself ^^

[@julianmac]

Thanks soo much for making this video.

[@idontknowwhattonamethis1029]

can you help in in this problem ( suppose i have 2 motors 2 prop 2 esc all the same but battery are 2s& 3s so now 1st components is at -2s and the 2nd is at 3s. Now tell me the load or amp drawn by the same motors will be the same or the motor on 3s will draw more amp than the motor on 2s

Can you use different props for different altitudes without having to change everything else? Because at higher altitudes the air is thinner.

[@BeyReaper]

Guys i got a problem with me set up. I am setting my systems like you show with the right type of prop motor esc and battery but i still get problems. When ever i plug in the motor and servos in the servos go haywire and the motor is unresponsive. People on hobby king tell me that the esc might not be supplying "clean power" and that the problem might be coming from there. Can you tell me your opinion on this.

[@samthekingyo]

Hey, what plane is that hanging in the top right? Is that an FT Slinger? Great video btw :-)

[@andyg6279]

[@TestECull]

Calculator's nice but it needs options for nitro as well. Wanted to see what it'd say about my Nitro Spear build but I can't tell it I'm using two 0.049s to fly it.

[@Chretze]

What's up lads! I got a question for ya: What is an example of a combination (if there is one at all) of motors, esc's, props etc on a small 250mm quadcopter to achieve a flight time of 20+ minutes? I'm not interested in racing it, I just want a compact "flying camera" to capture outdoor events. That's why I need it to be small, yet still have a long runtime while carrying a camera (if possible, even a tiny gimbal). I'd use carbon components to save weight wherever possible, the variables I'm not too sure about is prop size, motor performance and battery size. Thoughts?

[@conorhorgan183]

+Chretze look on hobby king and do your own research before asking other people to do it for you

[@Chretze]

+ConorCon Man03 I'm doing research right now. If you don't now anything, stay out of things that don't concern you.

[@conorhorgan183]

+Chretze Okay but i do not think there will be a combination to get 20 + minutes on a 250, you might need to get a bigger frame for a better and more efficient motor

[@Chretze]

ConorCon Man03 Hmm that's what I feared initially. I was thinking about building something similar to a parrot bebop 2 (pretty much a 250 frame size wise, triple blade props) which gets more than 20 minutes flight time. The thought of building something like it is intriguing so I was wondering if someone at flite test (or anyone else) knew how to achieve it.

[@mayurn9343]

how to select the motor n prop combo for different planes with different weight ,different minimum speed , different wing area,different airfoil shape. please help me for this i am really struggling in selecting the motor n prop combo

[@windage]

Help me understand this Josh, I thought the k in 'kv' stands for thousands, as in 'kilo'...rpm per volt in thousands. There is a k referenced in science as the 'equilibrium constant k' there is also Coulomb's constant ke, having to do with electric potential energy in a vacuum..what am I missing?

[@angelosalamat6824]

what will be the effect if i use esc with lower amp on a big motor example the required esc is 60amp on my edf, and i only use 30amp will it weaken the thrust of EDF? or it will be the same?

[@CHEFWILLAY]

what motor do you use on the ft flyer "im a noob so if you could dumb it down as much as possible if you could.

[@TheCrnic]

I have a problem. When I plug in my battery the motor goes full power in reverse. I am able to bind my transmitter while its doing this, but none of the controls stop the motor including the throttle cut. Any ideas? Note: During a flight I over G the plane, bent a wing and crashed. After replacing the wing (no motor components touched/moved) I went to do a flight surface check. When I plug the battery in the motor goes full throttle instantly.

[@g.zoltan]

Could you tell me about connecting the battery? I have decent experience with rc planes and I've seen that they are always powered/unpowered by connecting/disconnecting the battery. It bothers me that an external switch is never used. It's true that you'll eventually have to disconnect the battery to recharge it, but is there any other reason why noone places switches on their planes? I'd really like to do so, but it really bothers me that everyone else avoids it, like if it was something disasterous. Also, how about adding a fork to the battery's output, allowing you to plug in the charger externally, witouth having to access the battery? That's dangerous for sure, but is that all it?

[@tiahan603]

Quick question how do you see what amperage esc your motor needs

[@nickyrc3505]

Pls I need help here,I built a cessenar plane about 4ft long with a wingspan of 4.5ft being powered by a 2208 1100kv brushless motor with a 9*4 prop and a 3s battery but the airplane speed is slow..how do I increase the speed of the airplane..?

[@ElvisMoraes]

Uma sugestão muito obvia seria a de vocês colocarem legendas pt-br em seus vídeos. Eu sei que é uma ótima informação e com toda procedência, mas definitivamente não entendo perfeitamente a todos os pontos levantados. Assisto e obtenho as informações de forma quase que totalmente visual e jogo o áudio fora.

[@pass1985]

I think it is very difficult to do this (start from the front and make your way back) from a practical prospective. When I was designing my first scratch build hexa, first I estimated how much it was going to weigh, then I chose the motor (for example, tiger-motor shows how much thrust can be expected from a motor-prop combination), then the prop and finally the ESC based on the consumption ratings on the prop/motor combination. The batteries I already had (3S) so that constrained my options. I know for planes it is not exactly the same, but wouldn't the process be similar? Any thoughts?! Thanks for sharing your knowledge!

[@ewaldstander766]

Hi guys. I'm extremely new to rc and have little to no knowledge about the electronics, but im in the process of bulding my first scratch build plane the Old Fogey.I want to build most of them and love the swappable idea. I love the slow gentle flyer idea and would probably pursue that route. I need to go and buy a motor and prop(s) to use on my power pod.What should i get? I have a MAC8 18A ECS and 2x 3cell 11.1v 3cell 1300mAh batts Im going to buy a new transmitter soon but this is what i have at this moment. I live in South Africa and im hundreds of miles away from my closest hobby shop, so i need to go and buy stock. Please advise.

[@conorhorgan183]

+Ewald Stander you get the prop and motor than you see what the ratting are on them to get the right ESC and battery, the motor you need may be 20a and you only have a 18a ESC.
