RE: New Giant GP Super Sportster!!!!!
I installed a OS 1.60 in mine and it gives me unlimited vertical, I use all coreless high torque servos and a bison muffler, I mounted the engine sideways came out awesome, check out the pictures.
I also didn’t use the control rods that came with the plane, I went with a rod that was threaded on each end.
The Sullivan 4 40 rods are a perfect length, I also used their 4 40 golden clevises.
