If i flew with a 350mah 2s Lipo that weighs 23g, is it enough to get the correct CG?

Hi.
I just finished my Piaget, with Futaba S3114 servos and Axi 2204/54 motor on 2S LiPo. Very happy with this one and I have another one (the same!) waiting in the box.
There is one thing that bothers me, mentioned in one post, but never discussed.
There is a HUGE differential in ailerons with much more down deflection. What did you do for that?
Do you fly with such differential? If not, how did you compensate that?
Best

I don't mind the differential. It makes rolling circles easier. If you use a round servo control horn and if you place the push rods at the top of the circle (or maybe the bottom, I don't remember), I believe you can remove most of the differential.

Build question


Hey guys ...
When I buildt this I squared up the bottom fuse perfectly ( flat on the table )
then fliped over to put on the top fuse.... alot tougher to attach sq..
Now I see a slight twist to the elevator as compared to the wings ...
Can I fix this thru the carbon rods or do I have to cut off the top and reapply ??

Any ideas ???

Same thing happened to me. I just fly it the way it is, honestly, I don't notice it, but I'm flying outdoors in the wind, where precision flying is almost impossible with a plane this light.

fix it thru the carbon rods, easier to do.
A slight twist, is not a big problem.

Build Completed


Finished the build ... straightened out the elevator just fine thru the rod placement. Had to use a stronger servo for the alerons, the s75 I installed first couldn't recenter it some times with an extra long dubro arm.
Used the HS65 with dubro ex long arm and now it is perfect...
Made up for the expensive servo by using hx900 everywhere else at $3.49 a piece. Had to cut back the throw to 80% on the alerons..

Added negative expo to the spektrum,,, thats right uisn't it ??
-60% for all controls

Will post some pictures soon and maiden next day or so.
Going to be cold and windy tommorow

Power Plant


One thing I noticed when checking out the power system was that the motor gets pretty hot..... I am using the 12a plush esc with 3s 750 Rhino battery
also the 8 x 3.8 slo fly prop

any comments ??

burb ive got the same prop and lipo, great lipo, but its not for this outrunner. It works best with 2s, It hovers at Half throttle as well. Since the motor was made for 2s, the extra power on the 3s is brought out as heat.
