stevenchao,

I appreciate the offer but if I was going to swap out engines on my WH Extra 260 it wouldn't be the MLD 28cc. That plane for me is best suited with my OS 120AX swinging an APC 17X6 prop at 9500 rpm. I am getting ready to build a Warbird and it will be powered by a 26cc gasser and probably the Brillelli engine since I've had them before. I don't remember saying anything about the MLD engine not producing the numbers you posted, I just said that there are 26cc enignes on the market that produce as much or better rpm's for a better price. I'm a bargain hunter and I always look for the best bang for the buck. If your looking for someone to verify your numbers maybe someone else would love to volunteer their time for free.
