I love my comp-arf 2.6 and DA100/stock muff combination. 8611 servos. If I were looking for a new 100cc plane it would be 2.6 extra then QQ 102 yak then avaition models 35% yak. The 2.6 3Ds like mad and deserves a look even if you don't have the cash. I dorked mine the other day and it is already to get back in the air, just waiting on a couple a small parts.

Good luck with your plane. You will love running the DA100, I have almost 50 gallons through mine and it is the best engine I have ever had.
