Hi Rodney,

I have two 4s batteries moved back as far as they can go without doing any modifications. I also moved my receiver pack back. This combined with an improved tail wheel puts the CG just where I want it. I did not move the rudder servo back, but there would be no harm in doing that. My 4s 4000mah batteries are a little on the heavy side at 417 grans each. The total weight ready to fly is right at 10.5 pounds.
I’m pulling 80.8 amps/2410 watts on takeoff and in the air the prop unloads down to 70.0 amps/2160 watts full throttle.

QUOTE=rodney tanner;12194272]Hello X-30!
A couple of questions on your 8s setup, which I am also considering for
a Hacker A60-5s-V2 (295k) I already have.

How much did the CG move when you went to 8s? Weight of 8s packs?
Is there a need to move the rudder servo back to the tail?
On the APC 18x12 - how many watts output are you getting?
What is the all up weight including 8s with this setup!
Many thanks in advance!

To JAS
Did you check the wing incidence? 0.5 deg?
Is there any way to fit adjusters?
Thanks[/QUOTE]
