Can a 6s Power System Fly a 12s Plane? EF Slick 70" • AM670 • AM116 ESC • 6s LiPo • 18x8 Prop

I setup my Extreme Flight 70" Slick v2 with a T-Motor AM670 and a 6S battery to see if I could get away with a single battery setup on a 70" plane. This video answers the question.

Flight time on the maiden was 9 minutes. Flight time on the second (and more aggressive) flight of the day was 7.5m.

[@madatthesky7588]

Nice flight! Would still love to know the AUW 😅 Well done on the build, sir!

[@FASTFREDDIE-R.C.]

Awesome job filming Dave 👍🏻 Great video guys 💪🏻

Very nice maiden flight John. Nice work with the camera Dave. Keep up the good work gentlemen.

[@RCVideoReviews]

Hi Bill! Thanks for checking in.

[@davidpaker626]

👍🙂

[@hspeed3656]

Nice flying John, Ya those colors just pop.

[@RCVideoReviews]

Yes they do. I hate a cliche as much as the next guy, but I'm going to say it anyway: The camera did not do the colors justice.

[@LouCosmeRC-ov2ol]

Another beauty “The winds are coming from my left, so I’m going to takeoff left to right” 😂😂

[@RCVideoReviews]

oops

[@invertedIfly]

Flying a 70" 3d plane on a single 6s is nothing new, I've been flying my 71 3dhs aj slick for the past 11 years on a single 6s, my 72" extra and 73 slick were all single 6s. The am670 is a great motor, I have it in my 69" Raven., but if you can find one, the Motrolfly 4325-380 is even more of a beast, and will swing a 19x10 all day

[@davidpaker626]

Very nice color scheme And very nice flying airplane. Because of the very light Wing loading Due to the single battery set up, I bet this is going to Become one of your favorite airplanes, we'll see.

[@RCVideoReviews]

Thanks Dave. Definitely had some fun with it on the 2nd flight. And yes, definitely a looker in the sky.

[@Retset]

Congratulations on the maiden, your 6S decision and for your aircraft choice!! I have the FMS Pitts (V2 red version), also on a 6S 5000 (light 750g pack). It has nothing like the performance of your 6S Slick and I'm not sure it would manage 9 minutes (because it's flat out to look scale). Doesn't look like FMS made the best choice of power plant! They should have come to you for advice!

[@RCVideoReviews]

I'm quite happy with the end result. Definitely plenty of power for most.

[@alfiprasch]

Hallo T-motor 670 520kv or 480kv ?

[@weshillsberry6275]

Little did we kno extreme flight was doing this exact same thing for there new super chipmunk testing!!! I believe ben said he was testing that same combo to make sure the 670 combo was enough for that much plane

[@joefiganootz2425]

I feel the need for some trim too.

[@Prevettspecialdesign]

Great to see this video, I would love you too do a video with a 6s parallel pack and see how she flys, if your going to have to add weight it’s probably better that it’s extra battery capacity. 😊

[@RCVideoReviews]

You and I are of like mind. I thought about adding a battery in parallel, but that defeats the purpose of going to single battery in the first place, so instead: I ordered two 6s6200s. We'll see how that does. The 6200 may very well be the last twist of the dial to make this combo just right.

[@Prevettspecialdesign]

@@RCVideoReviews nice, can’t wait for the video. I love this sort of video, where experiments are carried out. I just opens up the doors for more people to get into this size of model, they can fly on a budget setup but at a later date go to a 12s setup at a later date if the wish. Keep up the good work.

[@RCVideoReviews]

I never really thought of it from a cost perspective, but you are right about that. 6s power systems are definitely more affordable.

[@epoweredrc]

Very nice, you proved what i always knew could be... never understood why they said 12S for 70 inch planes, I had a 74 inch 12S plane once and on 13S it was way over powered. I always wanted to try 6 or 8s but it was a older plane and kinda heavy. That is a great color scheme. nice Flight.

[@RCVideoReviews]

Thanks. Yes, this plane is capable enough on 6s. We get very much addicted to the crazy power ratios available these days.

[@phillinuptyres]

I would love a follow up on this video! what are your thoughts after having the setup for awhile?

[@RCVideoReviews]

I went flying a week after this video with no cameras. I took this plane and the Avanti v2 only. It was a very good day. The best description I can give is that the power is sufficient to do everything I currently know how to do. It doesn't have the ability to do a "hole shot" out of a hover like some of my setups can, but it easily hovers and accelerates going straight up. I think the only negative in this setup is the flight time is *slightly* lower than similar planes--but only just. I think this is an easy yes--I would do it again.

[@beonyou]

Nice flight. What is the plane weight on take-off ? (full weight with lipos, weight addons, aso) ?

[@JokerAL760]

I was wondering if you have checked out the StinGRpower gear reduction setup? Would be cool to see you do a video on a 85”-105” EF/Skywing plane with one of those electric setups in it!

[@RCVideoReviews]

Oh yeah, those are definitely cool...a little spendy, but yeah, I'm aware of them.

[@3dholicpilot522]

That inspires me for an interesting setup... AM670 on Skywing Slick 73" with 6S x 2 parallel packs for longer flight times for IMAC... Do you think it will suck a lot from the pulling power with the second pack added ?

[@RCVideoReviews]

Very good question. I ordered some 6s6200s to maybe help with the weight and give a little more flight time. I'll try to discuss in the next PilotJam after I get the batteries and fly with them.

[@beonyou]

Hello. I'm looking towards the EXTRA 78'' NG ... In comments, i read some fliying 73-74'' with 6S Lipos. What do you think about flying the 78'' NG on 6S ? Way more weight on it ?

[@RCVideoReviews]

Oh, I don't think a 78" on 6s would make me happy. This is about the limit IMHO.

[@itzjoeylo4501]

Using a dedicated power supply for the electronics, did you remove the power lead from the ESC…? Only using the Ground & Signal wire from the ESC…? I’m currently assembling a ARF and I would rather not depend on the flight pack for servo and receiver power. You briefly mentioned this, and I was curious about the correct way of setting it up. I have a few power eliminator adapters, that I considered using.

[@RCVideoReviews]

Yes, I removed the positive wire from the ESC connection and taped it down to the ground/signal wires.

[@fox2media880]

I'm surprised how well it ran on 6s. It makes things so much more affordable in terms of motor, esc and battery selection by going down that path. Looks like you could easy do the IMAC sequence on that setup twice (as required in comp flying) in the flight time you got out of it.

[@RCVideoReviews]

I haven't flown the IMAC sequence, but I've seen it, and I definitely think it has enough power to do the sequence, but I'm hesitant to say for sure on flight time. I just ordered some 6s6200's. Those might solve any lingering issues. And yes, 6s setups definitely save some cabbage.

[@fox2media880]

@@RCVideoReviews Yeah, I'd be curious to see how you go on a 6200mah. I'm shifting to 6000mahs now on my EDFs as I want more flight time. What brand batteries do you use?

[@psj47]

I'm new to electrics, so this may be a dumb question...Since you needed some more nose weight, couldn't you use an 8s battery instead of 6S ? Seems it would give you more flight time as well as a good CG without weights.

[@RCVideoReviews]

The motor and prop are designed for 6s. Usually not a good idea to add voltage without making sure all the elements in the chain are spec'd for the additional voltage.

[@scrubsr1304]

Which KV did you go with on the AM670- 480 or 520?

[@RCVideoReviews]

The 520.

[@ArtofTaxidermy]

I’m flying my 74” with 6s no problem. A 70” would be no brainer.

[@dalegregory3019]

John, after 6 months, are you still happy with the 6s setup vs. 12s?

[@RCVideoReviews]

I switched it to a 12s setup. It was ok for more mild maneuvers but it didn't build up a head of steam for things that required a little more momentum. I also liked the balance better with more weight on the nose.

[@dalegregory3019]

@@RCVideoReviews thanks for the info. I appreciate it! I wonder if 8s would be a good option.

[@RCVideoReviews]

It might, but you'll still need to deal with the weight to get the balance right.

[@ArtofTaxidermy]

Nice … I fly my 74” on 6s.

[@tpdmotor13]

Curios why you state you only fly electric and never gas. About to hear down this path and curios about your reasoning. Thanks !

[@RCVideoReviews]

I have zero interest in IC setups. Electric does everything I want/need. Don't care for the mess, fuel, fuss I see all the time with IC setups.

[@LouCosmeRC-ov2ol]

@tpdmotor13, for me, I could never see myself in an airplane like this being electric. It’s like buying an electric challenger, or an electric Camaro. no brummm brummm… lol

[@re3065]

@@LouCosmeRC-ov2ol IMHO - I have a over 50 planes BUILT - another 62 NIB - of all different shapes and sizes up to 2000MM and they are ALL ELECTRIC. I have not flown IC for over 15 years. NO MESS, NO STARTING ISSUES and NO ADJUSTING - just hit the throttle and GO - Electric is either ON or OFF - 1 or 0 - cannot get any easier than that. - IMHO

[@old-rcplane-phart]

Big bird maidens are scary. No gyro (I've not used a gyro, never been a fan myself. ), adds a bit more nerves. Gyros don't make great pilots, IMHO. Thx to all YOUR videos, u converted me from an iX20se to tx16s. I can't scream as to how much ppl r overpaying for spektrum junk! I learned the expensive way!

[@old-rcplane-phart]

I 'had to' have the hangar 9 ultra stick 10cc. Took 3 ounces of lead/brass in the nose using a 6s/7000 pack. It's still tail heavy. Traded it to a buddy. He put a safe rx in it & loves it🤷‍♂️🤪. Different strokes 🤷‍♂️

[@dronepilot260rc]

Flying any big wing plane is Childs play without a gyro. Try flying smaller 500mm ect wing planes with no gyro and see how well your skills truly are 🎉

[@RCVideoReviews]

Totally agree! That is the key point. Anyway, the plane did great. EF products just inspire confidence.

[@re3065]

I have stabilization on a switch. When it is TOO WINDY for other RC fliers to fly, I turn ON my stabilization, go "3 mistakes high", turn OFF my stabilization and perform my aerobatic maneuvers and when my battery time is telling me it is time to think about landing OR I am done doing my aerobatics - whichever comes first - I turn my stabilization ON and come in for touch and go OR land. Also, I have the SKY to myself because every other flier is sitting and watching OR left the field. So I will NEVER put down having STABILIZATION available - ON an ON/OFF SWITCH for this very reason of flying in TOO WINDY conditions. Two more reasons - I have SAVED a plane a few times from crashing due to "dumb thumbs" OR my arthritis "kinking" my fingers at a particular moment by also turning on stabilization before the plane "tried" to go into the ground. Of course this is what works for me AND is MHO 😉

[@trustenbaker8766]

"Here We Go" (money to burn)

[@dbirds21]

6 minutes is a enternity for me. I get 7 minutes on my gas and about 5 on all my large scale ekectrics. I want this plane. I just bought the mike high rc 75 inch edge 540 delivered to my door for 350. Its no 75 inch plane. More like a 67 inch plane. Its absolutely well made for the off brad. Very impressed. Has all the goodies. Im thinking of using your power system for it

[@thomasseeley8124]

Can an overpowered plane fly with half power.....

[@RCVideoReviews]

I'll take Yes for $200 Alex.

[@thomasseeley8124]

@@RCVideoReviews lol

[@dbirds21]

all in all whats your take with the 6s power. good enough for smacking

[@RCVideoReviews]

The power is acceptable. The only downside is flight time is a little on the short side around 6m.

[@deanedeane4318]

Great plane , flight and job Lads 😉😎
