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.
CG for the Arctic Cat is 10mm in front of the ridge on the bottom of the aircraft.
Yes. Upgraded version right here
