I am also upgrading to kyosho magnetic mayhem:

1-Would the pt take off from grass with the kyosho motor with 6 cell?any one tried that or should i make it 7cell.

2-Can the kyosho magnetic run 8 cell,3000nimh??? or that would fry the motor?

3-Do i need a battery for the reciever considering that i got a 6cell 3000nimh and a speed controller with motor power cut off to save power for the controls.is it safe without the reciever's battery?

4-Wheels, the manual recommends 2.5" wheels, would 3" or 3.5" help the pt to take off from grass

5-Where could I locate the thread that shows how to add aerlions to the pt.
