Will have to try doing that since I lost one of those batteries mid flight yesterday. Speaking of which what is a reasonable radius that one of the batteries might be from the plane if that happens? I searched for an hour yesterday evening for it and plan on looking some more today during my lunch hour. The plane was probably 30 feet off the ground when the battery disconnected. The place where it happened has a great deal of unmowed grass so it could have settled down into it.

Good luck with that!

I lost a 3S 2200 when the canopy came off my Cularis during an outside loop. Never found it. Mostly short grass and a hedge line...

I replaced the Eflite velcro strip in the plane with a stip of the blue stuff from HK. You could velcro someone to the wall with that stuff so I think it might do the trick for keeping the battery from bailing out early.

Guess Horizon doesn't test these at anything much over 1000' ASL.

Had a couple of short, trimming flights without too many incidents but when I tried a loop at about 20' off the deck on the third flight the little MIG-15 just didn't have the thrust to finish it up here at 5000' ASL.

The nose dropped out of it and, in the race between airspeed and distance to the ground, the ground won.

It's a neat little plane but I'm going to put it down as a failed high altitude flying experiment and go back to flying prop driven birds which I can swap props out to get the desired performance.

Did you use the stock battery???...If so, that's a lot of your power problem...I'm only at 500' ASL and can do consecutive 100' loops from level flight....However I'm using a 35C 300mAh battery...I also gained a considerable amount of air speed when I removed the landing gear...ROG takeoffs were a blast but the weight and drag penalty were very noticeable...

Yep, stock battery. I have some little 260mAh 35C packs on order from HK but they hadn't arrived yet. Guess I was asking too much out of it.

I can glue stuff back together and try again as well as remove the LG when the batteries arrive. The nose is pretty munged up but it can be salvaged as well.

Will think about whether it's worth the effort.

Ronin - go to 3S. If the air is that thin the load won't bother it and you'll get the right amount of air going through it.

Thanks Nitro. Might do that. I have a few other things to get tweaked out as far as airplanes go so the incident with the MIG sort of pushed it to the back of the line. If I get back around to her I'll try out a 3S pack and see how it goes.

I don't know if I just happened upon a good one or what---I'm very pleased with my MiG...It is much faster than my GP Sabre and more fun to fly...I can roll 'er over on its back with very little down elevator...But the AS3X system allows for a more aft CG and the MiG's airfoil is better designed for all around flight...

I'll get a hatcam vid this weekend if the winds aren't too bad...I may have to take off from work early on Wednesday as the weather service is calling for calm winds....Not that the MiG can't handle the wind---I just want to get a vid in good conditions....The thing is that this time of year it starts to get pretty dark here @ 4:30PM---And I don't get off until 4:30PM---BIG problem for flying in the afternoon without having to take vacation time to get off from work early......

ronin4740---Don't give up on the MiG as after sorting it out it is a GREAT flyer...Nitro has a wealth of experience with this plane and I would follow his recommendations...

After you have smashed up a couple of Mig 15's or just want to buy the parts here are a couple pics of the new Mig 29 that was designed to use two of the 28mm fans. Maiden in the morning if the wind stays down. If all goes well I will start a build thread.

Well looks like I will be tearing into mine...Motor wires are completely twisted in the way as well as a few servo wires.
