I'd say the 60 or 70 would be a great fit. The 85 fits too, but the plane was designed for a smaller sized motor. It all depends on how you manage the throttle, what exhaust you like, how you prop the motor, and what your flying style is... lots of choices, which is a good thing.

I have an eme 60 that pulls great, but I am selling the airframe it is on and the buyer would like to get the engine also. I have heard that the 60 leaves a little to be desired. Can anybody compare the gp61 to a da60?

I had the EME 60 with stock muff on mine and the power was just adequate IMO. Pullout from hover was lack luster. Any 60 needs a pipe as far as I'm concerned.

I put the DA 85 and can on mine,but haven't flown it yet. I really think it will be sweet though.

Really curious to see how that works for you. I flew one with a DA70 and it was plenty of power. Lots o' ching for that one though.

Very difficult to cg with just a 60, mine was always tail heavy. Now with the 85,it balances very easily.

Can't wait to re-maiden.

You'll be happy with the 85 power... but be prepared to prop it down a little. I wound up going with a 3-blade... 25x10 if I remember.

I thought about a dle85 but just don't see any out there, thought about gp88 since my 176's are doing good......settled on the da70 and loving it. At least the three days we've had that have been nice out Hoping to get some time on it this weekend with new 25x8W prop.

Oh and did you have to put the rudder servo in the tail? On the 85 that is.

We flew last week for the first time since December. The DA-60/RE-2 started and ran like it was last run that morning. I am too damn poor to keep buying this stuff over and over, the DA runs perfectly every time and really has great power (pun intended).
It was also the first time I ran the dual 3S batteries, regulated by the twin Castle BEC Pros, into the 9110 "Powersafe" receiver. I was concerned that since one put out 8.50 volts, and the other put out 8.49, the 9110 would pull from the 8.5V source all the time. That ended up being an unfounded concern, they were both drawing down equally. Neither BEC was even warm after landing. I had used twin 3S 2200's but now that it will provide full, consistent servo power all the way down to dead batteries, I just ordered some 3S 1500's to save about 1/3 pound AUW.
