RE: RC LANDER PANTHER F9F PANTHER ENGINE ?
I would put only a inrunner in it and balance it all. Trust me if you don't it will bend the motor shaft very fast at half throttle. A3575 kv is good to go make sure the can is 28mm and you can put just about any thing you want in there. Do they sell the RClander motors on that site? If not go to toysonics.com he has them at a good price too. Good luck and have fun and enjoy. I have the hunter hawker too.
