How do I land this thing?

got my mig-15 yesterday and gave it a little test flight today. the poor thing can barely get out of it's own way on 2s. good thing I have a 10amp esc on the way. I really had to throw it to get it going but once in the air it would buzz around ok. I'm using a stripped down flysky receiver with the servo wires soldered in and hot glued under the battery bay. it does leave lots of room for the battery

Well as I posted before, on my MiG-29 I changed the thrust angle to be a lot more up. and I took it out for a re-maiden today. it was a bit gusty and wind speed up and down. but I got a good flight in.
I hand launched it at 2/3rd throttle, it flew away perfectly nice and even. I didn't need any trim. 1/3 throttle, 2/3 throttle, full throttle and even cut the throttle and she does not climb or dive. beautiful!
at slower speeds it's hard to get her to turn.
I'm going back out soon as the wind is dying down, going to try to add in more aileron throw.
it handled the wind really well. the UMX beast was getting knocked around all over the place by the same wind. the MiG-29 was very smooth and stable

Hi I bought one of these, 35mm F-86s, A few months ago, as my first EDF and after only a few weeks of flying. I use a Dx4e. It fly's great and only took a little practice. The best way to hand launch is to throw with a lot of force to get the air speed up, Jets have little response when there is insufficient air flowing over the control surfaces.

The F-86 does tend to be a little tail heavy which leads to funny bank turning, the stock ESC did handle 3S, mine only fried, due to a blob of hot glue jammin the fan, this would of still blown the ESC on 2S. But I take no responsibility for any blown ESC on 3S, so try at your own risk.

Fly's quick and level with 3S I got 130gr thrust approx from it. Sorry don't have the std specs for thrust. Upgraded both servos to 8G and inverted the aileron servo and ran the links out the fuselage to stop breakage on belly landings on thicker grass.

I'm flying my MiG 15 on 4S....My ESC burned out after a couple of flights on 2S...I'm now running a 12 amp ESC and she really scoots on 4S...The stock motor can easily handle 4S with the stock fan rotor...I don't know about flying with a 6 blade rotor.....

Thanks. On low rates is it still touchy and how much room does it need to fly. (More than a larger plane like the Trojan)

Kevi, don't load the motor with more blades - it will only slow it down anyway...

Gotcha!!!...THANKS for helping me not waste $$$ on the rotor!!!

The wife was cleaning up my mess (she can't stand a mess and what modeler doesn't create one???) and I'm guessing that she threw away the canopy for my MiG.........Guess what I've been making tonight from scrap foam!?!?!???!!!.......I've got it primed and ready for paint...

Kevin

I found the canopy but had to go dumpster diving to get it...Even digging through your own trash is NASTY!!!.....

Crikey!

I just cast my Mig canopy so I can make a vac-formed version to allow more lipo space under the hood...

I just got the A-10 yesterday looks decent, the rear tail surfaces were a little warped but I bent the foam back in shape just fine. I haven't flown it yet but would you guys suggest throwing this bad boy or taking off from pavement? It is tail heavy to say the least with the landing gear on it can't keep the nose down without the lipo.

Are you going with clear plastic? Don't like those black canopies.

Can you explain how you're casting it? I might try that myself.

I am using 2, 2s 360's and mine cg's ok with the landing gear on. It takes a lot of runway before it get's in the air so make sure it is tracking straight if you run the gear. Of all the 35mm jets I have, mig, f-18 and a-10, I think the a-10 is the better flyer of those 3.

And it shouldn't! If she balances out without the lipo you've got a problem there.
After all you'll be flying WITH the battery so it makes sense that she's unbalanced without..

angelo - I use the dental casting rubbery stuff called alginate..smells like peppermint. You set up the original canopy in a little square container slightly larger and higher than the canopy. Make a stand-off so it(canopy) sits a little higher off the base. Pour in the Alginate and let it set (takes a minute). I let it sit there for a few more minutes and then peel it out of the container and sit it up side down to let it dry a little more. Then, mix super fine casting powder (plaster of Paris) into the alginate mold and you get a strong copy of your canopy. Use this to vac-form or shrink plastic over.

They can still be a bit skittish or twitchy but thats due to there small size, as soon as you turn they are on a knife edge before you know it, a larger plane will take some time to lift its wing, so the larger ones seem more docile. you Should be able to fly on a normal oval, say 200x200 meters, but it would Really depend on your flying skills
