Sounds like a nice combination. If you get a chance, pictures would be great, but first things first get the DAR visit completed.

Albert, valuable post...knowing the left to right differential is

important and great to read.  Did you mount your batteries right of the

longitudinal centerline?

Great data point Albert, thanks for sharing.  How about the same for more of 

the finished airplanes?  Also the empty CG location would be nice to know.

The battery is in Vans location on the centerline. I was a little surprised

to see the extra 6 lbs. on the right wheel. The trutrak servo is in the

right wing so that's certainly part of the difference but I didn't weigh it

before I installed it.
