Upgrades to the SkyFly
 

I have had and flown a SkyFly for a few months now. It is my second plane after my firebird freedom bit the dust. I have a few questions about trying to get more power from The SkyFly and wanted to inquire if anyone has attempted any of them

1) Can I upgrade the motor from the 380 to the 480 without hurting the speed controll

2) Has anyone successfully flown with a 7-cell NiMH in thier SkyFly, or knows if this is a feasable option. I am worried about damage to the ESC.

Thank you for your input's
