When are you going to post the specs on the new D3R and D5R. I'd like to know more about it before deciding to get one.
My D3 I finally was able to run properly after sealing the leaks on the carb. Does this engine really like to run on the lean side (hot!)? I'm using 25% fuel and if I don't give it enough lean then it drives like a grandmother, but then if I lean it to run competitively, I get up to 300 F temp range huh!.
Thanks,
Roy
Dear Roy,
The specs of Draron and Dragon Racing engine are all the same. The modified engine just has better acceleration. I would suggest you to buy modified version because our modified engine is inexpensive.
Have you try to take out some head shims? When the engine has enough power than you don't need to lean it too much. With 25% I would use 0.4mm shims and #7 turbo plug. Sometime we need to do reverse operation.
