speedster 1919

My Feedback: (3)

First I would put a heavy hub nut on engine to balance plane. Once balanced I would make a power judgement. That model is a 40 size and a 91 or 100 would tear its guts out. A 72 or 82 Saito or 70 Magnum would be better.The OS 70 is know for tuning issues. A Super Tigre 51 would be perfect for 2 stroke. It weighs more than GP42 and does not like high nitro content........
