The DA is stronger than the BME 102, but either engine will have more than enough power for a 26 lb plane like the Sukhoi. The BME will require more nose weight than the DA, so the overall plane weight will be the same. You might also consider the new 3W-106, weighs the same as the DA and at least as much if not more power.

BME also has new Extreme 110cc motor coming out, but it hasn't hit the street yet. You would be a guinea pig on this one.
