Freewing F14 underpowered

Hi > Just one thought, have you Calibrated/Learnt the ESC`s with your transmitter`s Low and Full throttle range using a programming card or using the ESC bleep tones?

Hi. Could go up tomorrow for around 2pm. I have an adaptor which I use on my mustang. It's for XT60. What connectors are on your packs?. Cheers

Yes did that using the transmitter and the beeps according to the online from hobbywing.

To verify that the ESC is getting the full range of signal pulses, around 900us to 2000us (1500us is deemed as half throttle) may I suggest you calibrate each ESC separately. TX on and full throttle on stick. (Trim in mid position) now power up ESC and immediately after the first tone pull the throttle stick down to low. The motor should a few seconds later chime with the number of cells and then a longer tone verifying motor armed. However, you may have already done this re-Mike's earlier posts.

Judging by your amps/watts figures (nearly 2HP or 1700 watts) that is a lot of power. Have you visited Motion RC's community www.hobbysquawk.com/ to see other users inputs and queries? Might have to do a lot of scrolling though!

I don't see where they are recommending 60C packs. They even have a link to a 40C 4000mAh battery in the "requires" field HERE
Not saying that 60C wouldn't be better, but cannot see where it recommends that.
