can I use 3-cell 11-1 910mah on the stryker f27b
with brushed motor

I'm sure you could but your center of gravity will be off and your flight time will be dramaticallly reduced

Thank you
The stock set-up is ok Messing with the lipoly seems like a problem
I just got into heli'''s that's a big problem but fun
Ever use any raiden tech chargers???

I use a thunder powere 11.1 2100 mah and an art-tech 11.1 1800 mah batteries. I've been advised in this forum that running with the 11.1 volts will eventually burn out the receiver but have been running for two years now without a problem
sorry, not familiar with the charger..

Why would using 11.1 v Lipo burn out the receiver? It's the ESC that, hopeful you use, has the voltage regulator to set the voltage down to between 5V and 6V for the receiver.

I stand corrected..
