I got my Impulse 32 together and was starting to test props. Because I bought this with all the hardware and no electronics, I opted for the Leopard 4082 1600KV X2 and the OSE 150A ESC. I had to cut out some of the stock motor mount to make room for the larger diameter motor and a rear motor support.
I started with the trim tabs parallel to the bottom of the hull and raised 2 to 2.5mm instead of flush to the bottom of the hull as it came stock. I also started with the strut parallel (0 degree angle) and the stock prop. Batteries are 3s SMC DV Extreme 6900mAh "135C" to make 6s. As Jesse J said, it was hopping all over the place. I added 2 degrees negative angle to the inside trim tabs and about 1 degree negative angle on the strut. It's slightly better but not by much.
Anyone have a working setup on their Impulse? Do I go wrong moving the trim tabs up? Should I put them even with the bottom of the hull again and start trimming from there? I admit that I have not had much time to do much testing and, as it is now Nov. I'm rapidly running out of time before the lakes freeze over. So any help would be appreciated!Impulse inside2a.jpgImpulse 32 trim tabs.jpg
