Friends,


Working on the adage that .......'the only dumb question is the one that was never asked' and being a recent convert to electric power,I seek an answer to a question to which I seem unable to find readily herein.[>:]

I am setting up a GWS E starter foam trainer as follows :

1. Stock Airframe, Stock supplied engine ..er ....motor, GWS T4 channel starter radio with tiny servos, ESC and receiver.

2.The GWS E Starter Manual suggests using a 7.2-8.4V Nicad or NiMh 'power pack'.

3. I want to convert it to LiPo power. I imagine a two cell 1200mah pack should work.

Questionsi : i. Will my proposed LiPo battery set up work or would you reccommend a three cell set up ?

ii. Can I use the same ESC or is there a special ESC for LiPo Batteries as opposed to Nicads/NiMh's ?
( Either ESC information appears to be an esotoric art form or I am dumb after all )

iii. Can I switch between NiMhs and Lipos ( while taking care of the CG) Cant think of a real reason why I would, but neverteless a dumb question.

iv. What equivalent 'Brushless' motor would you reccommend if I decide (or need) to hop up the above if the stock motor proves to be a weenie.


Any other thoughts/advice on the above are welcome. BTW I am an experienced RC pilot. ( 2000 + flights) on Gas powered planes.


Thanks for your help.
