RE: Mig 15
I like this plane a lot. I did change out the TX and receiver so I could use my own, that has Expo.
Not that this is needed as the plane will fly OK with the included TX/RX.
I do recommend you give the receiver a bit of a "knock test".
Hook it up to a NICD pack but not to the ESC so that the servos are powered but not the motor.
Then lightly tap the receiver while moving the controls.
You want to make sure that there are no cold solder joints, which can often occur if the assembler is having a bad day!
Do likewise, and also do a range test.
This plane gets out of sight easily, so with the included TX keep it within 600 feet for safety.
After 800ft you may loose the plane... one reason I upgraded the TX/RX.
The battery packs are my only bug-a-boo.
The included pack works fine, but the flight duration is about 4-5 minutes at moderate to upper throttle.
The first time I flew mine, with the included TX, someone else took up a foamy Sabre at the same time!
Needless to say we had a blast chasing each other around the sky and I ran out of power before I noticed it.
I brought the plane in to a safe landing, but I would like larger ( 1800-2200mAh ) packs instead.
The battery placement does not lend itself to this without some "constructive surgery".
I've been meaning to try to cut the intake divider a bit to allow a larger pack, but I haven't had the time to do so yet.
So I do not know if this is possible yet.
