RE: Walkera 5#10
Yeah the 14.99 from HK is the deal I got on batteries. I havent done any mods to mine yet its totally stock. I have had over 20 flights and no crashes or mechanical breakdowns. Never had a blade strike. Not a single problem at all, you just have to remember to re center your trim dials before every flight as well as adjust your rudder trim left throughtout the flight. Thats not a big deal though.
If you do decide to modify yours post some pics and keep us posted on your progress! I'd like to see it
