Very few HK models have printed manuals - keeps costs down.
The Bixler is about your only option that has any chance of fulfilling your needs.
Receivers cannot be run directly on the 12V battery. You need a BEC that lowers the voltage to receiver requirements.
In addition, if you have never flown before, if the Corsair you have is the low gull-wing US fighter aircraft, you will be very unlikely to have any success in flying it.
You will be best advised to get a high-winged trainer to learn with. A Bixler is one to look for at HobbyKing
Our inventory is admittedly less than ideal at this time though it will be improving soon. Please keep an eye on the site for updates. Parts for the Trooper should be forthcoming.
Expecting them to return once everyone gets back from Chinese new year
So long as it runs any normal servo, analogue or digital it will run fine.
I have run the same system on a 25yr old JR 27MHz radio no problem.
Possibly. But, it will need VERY careful coaxing back up to 3.0V or so per cell by charging on a low NiCd or NiHm charge. Then it should balance charge, but at no more than 1C rate.
However, if any cells are at 0v before attempting the above, dispose of it.
If it balances up ok, give it a few charge/diascharge cycles and check it out.
IF you do try this, watch it like a hawk as it could be damaged already and if it warms up a lot or puffs up, stop charging immediately and dispose of it.
Upside down should be fine with reversals innplace, but vertically is not.
