A Weird Little Jet (Freewing F-5N Tiger II 80mm RC Plane)

[@AllanG1914]

This has become one of my favorite planes. At $350 from Motion, its a steal!!!

[@AviationAstro]

Spot on for the CG comments. I tried going aft with my battery by only 1/4" and the flight characteristics were noticeably worse. Overall, it's so much fun to fly

[@williamwallace9427]

The f5…one of the sexiest airplanes of all time

[@TwoBrosRC]

I'd prefer the X-29 or the F-20 variants but the F-5 is still pretty neat looking.

[@christopherruble3116]

We will have to agree to disagree on the x-29 😆😆😆 but yeah the f-20 was gorgeous

That final landing was intense ... nice job sticking the landing. Very Good Flight

[@TwoBrosRC]

Thanks Nick! It sucks that the airport is in lowlands susceptible to flooding but such is life if you want to fly off free pavement.

[@txkflier]

I made 2 flights with my F-5 today and 2 flights on Monday. I put an AR637T in it for SAFE mode because my vision isn’t good enough to see its small wings when it’s at the ends of the field. I don’t use much AS3X gain on my EDF’s because they’re fast enough the turbulence doesn’t bother them very much. I usually start with 30, 40, and 50 percent on roll, pitch, and yaw and hardly ever increase it. My F-5 flies and looks great and isn’t really that hard to land. It just needs to land a little bit faster than the others. It’s one of my favorites..

[@chiefbd]

I just did a maiden flight with this plane and it is one of my best. It is fun and smooth and definitely can move quickly. Glides right through the sky

[@chrispayne2269]

If you reduce your flaps by half on Landing you can glide it all the way to the ground just perfect.

[@Tantrum791]

Great looking plane! Good flying!

[@TwoBrosRC]

Thanks man!

[@acw400]

Nice review. I totally agree with you regarding CG. The front most side of the provided range works great. The model is very challenging to fly with the rear side, especially without gyros. I fixed the fuselage flex by adding some carbon tow at the junction between both fuselage halves.

[@TwoBrosRC]

Carbon reinforcement sounds like the way to go here. Shouldn't need done though.

[@jimrichardson8575]

These are the airplanes that I was supplying engines for during the Vietnam War. We stripped the engines out of our T38 Talons, and sent them to Viernam: Where they were installed into the F5 Tigers.

[@mongoose4117]

Jon looked amazing!! You just confirmed what I thought about my f-5. Shes a wild machine. I found out the hard way about getting tail heavy at all!! Holy! I do love my f-5, tho. I have my c.g. about 3mm behind the the front wing screw but im going to move it forward a bit more. I was about a half inch back and it got ugly, quick!! She's back and flying the sundowners brown aggressor!! Love her shape as she blasts by!!😍👍🌟💯🍻 Oh yea...im very pleased that you are keeping your f-5!! She looks sharp.

[@TwoBrosRC]

It's not worth it to push the CG back - whatever gain you get is offset by the total lack of controllability.

[@mongoose4117]

@@TwoBrosRC I know, right. 😆 in the next few days I will get her out and see how she flys. I pushed her c.g. forward 4mm of the front wing screws center point. What minwax do you like to use? Do you use brush on?

[@mpojr]

thanks for the heads up on the F5 ,,,l am going to mark this one off the list

[@ojeezrc]

Great flight . I had a problem with my maiden . I had the cg back and I was doing high alpha from take off . Then my nose gear won't close due to the door and when I make turns it took forever to turn .

[@crazyaces9586]

Nice flying Jon...i love mine Camouflage and the in runner. I fly mine like i stolen it 😉. I knew you like it what's the coating you use ?

[@TwoBrosRC]

Thanks man. I'm using Minwax Polycrylic brushed on the foam.

[@old-rcplane-phart]

@@TwoBrosRC Also have a spray. BUT, the best is the brush on IMHO. It looks much more shiny brushed. Just be sure to clean the foam really well be coating! Ill use 70% alcohol on a microfiber towel.

[@BoudreauxBoysRc]

Now thats perfect battery placement 🤣🤣 super picky about cg but once you get it dialed its amazing i run a 3665 2000kv platinum pro from fms with 15% timing to get 150+ mph with motion rc 8s esc flew it 7s also not much difference in speed tho but by far my best sounding jet and looks fantastic in the air 4:56

[@moochasas]

Do you have a link to the covering you mentioned MINwax??... here is Australia it may have a whole different trade name..... minwax here is a polyurethane wood protection product. Cheers

[@TwoBrosRC]

Water-based polyurethane is all you need. Minwax appears to be identical where you are, though. There's oil and water based version of it. Minwax Polycrylic is what you're looking for.

[@moochasas]

@@TwoBrosRC Cheers...... thanks.

[@looneytunes47]

All my planes get 3 coats of minwax from the minute i get them ive saved so many could have been ugly crash senerios by using that stuff makes the airframe so much stronger n rigid

[@chiefbd]

Hey Jon, have you ever thought about getting the Freewing SU-35, I am curious what you would do to that plane with its thrust vectoring?

[@TwoBrosRC]

It's not even a "thought about", I'm getting it before the year is over. Probably in time for Wings over Springs in September, actually. I'll have to do some practice with it beforehand though.

[@chiefbd]

@@TwoBrosRC awesome. I bought the plane but haven't maidened it yet. But you inspired me to take the F5 to the field so I'm going to at least fly a few packs on the F35 soon. Will try regular flight first then try a thrust vectored flight

[@velvetsmoooth4980]

What are your thoughts on if I were to take out the landing gear to reduce weight and hand launch/belly land on soft grass? Do you think it has enough power?

[@TwoBrosRC]

Hand launching might be difficult since it has a very high wing loading with stubby little wings. You won't get much weight reduction from removing the gear, and the full flying stabs will be exposed to anything on the ground that can tear them apart. You're better off sticking with the wheels.

[@Donkey_Balls]

👏👏👏👏

[@tructran8783]

Love how you fly that F5. Is it the stock 9 blade high performance F5? Why do you want to change That stock 100A ESC ?

[@TwoBrosRC]

Thanks Truc! No, it's the FMS Pro 2100kv motor with an Avian 100a ESC. I wanted to take the stock setup and transfer it to my 80mm F-14.

[@skynyrdd1]

Great video Jon, I've just picked one of these up, can I ask do you have an elevator/flap mix?

[@TwoBrosRC]

Yeah, I just have some minor down elevator added for flap deployment to keep it from ballooning.

[@skynyrdd1]

@@TwoBrosRC Thank you, really enjoy your channel.

[@klemzy2170]

Nice videos and everything you said made us better rc pilot :D.. I have also one question.. You talked about airplane wing stall.. how do you know where the plane have that angle for stall it.. I flew the yak-130 70mm and suddenly he lost speed and fell down.. i cant do nothing.. i know i stall it but i was strange for me because i have speed :-).. I have su-30 and i scare to fly it just of these stall angle hehe :D.. how can i improve that problem :D.. best regards from europa

[@TwoBrosRC]

So that's the thing, you don't really know what the critical AoA is - you just intuitively feel it out and get an idea of how hard you can pull the aircraft into a turn or a loop before it begins to experience an accelerated stall. Accelerated stalls happen even with a lot of airspeed - like I said in the upload, wings can stall at any airspeed. The faster you go, the more you can get, but the model does eventually hit critical AoA and break airflow over the wing if you pull too hard. You just have to test it out and see where the limit is, and then learn how to navigate around it while you fly.

[@mrparamedico25]

Excellent flights with that beauty, I'm about to acquire an F5 too, only I'm worried about the landing, will the landing be similar to that of the 90mm f18? what do you think?? since both land fast.

[@TwoBrosRC]

It's very similar to landing an F/A-18 with full span flaps. Keep 25 to 50% throttle on approach with the flaps dropped, otherwise it will fall from the sky but look like it's flying level. We have a landing tutorial for it that should help: kzbin.info/www/bejne/qIelqpymf9N2aKc

[@henryairconcepts2999]

have you tried using 7s? your fms edf can handle it. you'll get more push

[@TwoBrosRC]

I don't see the point in adding more wing loading just for added thrust.

[@-2772-]

freewings best jet

[@TwoBrosRC]

Lol, definitely far from it. The F-22 and Su-35 are significantly better in many ways.

[@rlbutterfield]

Looks like there’s quite a bit of oscillation.

[@TwoBrosRC]

Yeah, I mentioned it in the vid - I just didn't anticipate how much pitch oscillation I'd get at full throttle. I need to adjust the throttle to gain mix for pitch so there's less effectiveness at full speed.

[@M4rkmcc21]

Jon u say u want to upgrade the Avian 100A esc.. did u mean as to a 130A or is the 100A a little faulty? Cheers

[@TwoBrosRC]

We thought the 100a was faulty. Haven't flown the F-5 since this.

[@mongoose4117]

Jon, what minwax do you like to use?. Is it brush on?

[@TwoBrosRC]

I prefer brush on, only because I'm used to it. I'm sure spray on works well too.

[@TwoBrosRC]

I really don't put a ton of thought into what's "best" - I tend to appreciate every jet for being what it is but in its own unique way. It's hard to quantify what flies best because some jets do things that others can't, and vice versa.
