Jeff248,

I'm sure that a Moki or Mark 1.80 would work as well for your application as the DPM Blue Head engine. The only significant difference is in the compression ratio allowing 15% nitro fuel in the Blue Head engine whereas the Moki and Mark engines run on fuels with 0% to 5% nitro. Frankly, 15% nitro fuel is more expensive so the DPM engine can be a tad more expensive to operate. You should be able to locate a good Moki or Mark engine on the RCU Marketplace or on eBay.

Good luck and Merry Christmas!
