I keep seeing the K&B/Veco 61's beingmentioned. Clarence Lee still puts together his version of the ckassic K&B .61 with PDP porting. I obtained seveeral of them last year and picked up several used versions by auction. One was an old Veco with his stamp on it that was of the earliest design with the smaller bypass. The best one, which was a more recent Veco with Perry pump carb, turns an APC 11x7 at 13,300 with one of his modified mufflers. His new engines are hand fitted from Mecoa parts and include the new twister style muffler that has an internal baffle. Quiet, butrestrictive. I found the baffle to reduce the rpm on one of the engines by about 500 rpm. The increase in noise when removing the baffle is noticeable, but not too loud.

On the ore ballistic planes, I favor the Rossi. Ialso had luck with the OS VF, but was not as powerful as the Rossi. Interesting thread.
