Guys,
I am a couple of stages further.
I have remounted the quad with the new SunnySky's, New ESC's.
The ESC's were very hard to get fitted as they are slightly larger than the old ones. The front ones I needed to put in sideways to make it fit.
A lot of soldering: Power board, motor wires,... Going crazy
Fired it up and all is beeping as it should. I also checked the rotation of the motors and sorted that out with revering the ESC wires.
I have got a 4000 Mah Genns Ace 4S battery. I wanna get some flight time with the quad. However, the place at the back is getting too heavy I think with this new battery. This is going to alter the Center of Gravity substantially. So maybe mount it in the middle on the top. Not the best thing when looks are important but it might allow the quad to fly better? It also givens me som room to put some stuff at the back.
What do you think?
Thanks
