I thought about 2 cells also, how would I go about that, using the same approach as the duel wire feed to the EDF’s?

Two cells, that would add more weight

Not sure I understand the question? I'm using One 2s1p battery pack through one ESC, motors wired parallel.

Still thinking about control options- probably A/E with pull-pull.

2 cells

In other words If have 2 GWS Ni-MH 750mAh 9.6v, one each to power the set of twin GWS EDF55-150. How would I go about doing that.

My control options will be as the B-2 by GWS.

I am only using the aileron for Flight control and the no elevator on the rear horizontal stabilizer, it’s already at a 45*. Tested this out on a small model size no aileron control surfaces, the rear horizontal stabilizer (elevator) set at 45* caused the plane to pitch up and loop. When I sling shot the model foamy. Then I added the Aileron on the wings to control the pitch & flew stable. I did a short taxi run on the larger size, it flew off the ground about 1.5ft in the air then it pitch right a little, before I droped the power. It's ready for flight.

Two batteries, two motors...


Make sure the esc is enough to handle the needs of both motors. What ever you use for a single, double it.

I used 1.25 inch aierons and the elevator was 2 inches of the back between the stabs.

It has not flown well either...

I am taking a new approach to the problem this year... I am cuttting it out of EPP, Spar it in flat carbon and using twin johnsons and LiPos... drop the weight, increase the power.

Skunk, here's a good thread on measuring CG: See post #7.

Skunk , I think you're gonna' have to use the ailerons and V-tail ... the elevator between the fins didn't work well for us on our profile .... tried everything else .... the A/VT seems to be the correct way to go ..... especially since nothing else worked .... Good Luck !!!

This could be my plane. Its the same set-up I have on mine. One thing I have thought about is not splitting/hinging the V-tail control surfaces. One day I will use all of the control surface and pivot it with a dowel.
