You most likely will need a DA-60 with a pipe or a DA-70 to get good performance
I have the EME in a 3DHS 87' extra that is around 17 - 18 Lbs it pulls that plane around Ok I would not put the EME 60 on anything bigger

Thanks for posting. I had the EME 60 in a 3DHS 98 Slick with a MTW front dump canister which was plenty. I might try another Slick or the extreme flight 88 Edge.

I agree you may have to pipe a 60cc for the EF yak if it gets near 20 lbs for the rediculous power we like but I dont understand why it would have to be a piped DA 60 and not a piped EME 60?.

The slick is probably heavier, but they are close. Cody's 91 yak was exactly 19 pounds with gas with a DA-60/RE2. It is the 91 extra that is big and heavy.

A EME 60 on a pipe is about the same power as DA-60 stock exhaust

Default New EME engines

Do you have data to back that? The EME-60s seems turn the same prop maybe 100 RPM less than the DA on stock exhaust from our experiences up here with multiple engines of both types. We have a lot of experience with the DA on pipes, but not the EME.

The DA/RE2 does 6800 on that prop. So 100-200 less RPM. The DA-70 does 6700 on stock exhaust.

Default eme 60

im flying a 21# christian eagle with the EME60 with elec.start and it performs very well and that is at 6000ft ASL. it does not have the power you guys with your 3d planes want but I would hold this engine up to a DLE/DA anytime, it pulls this 21# drag bipe around very well, with vertical.
But then again its not a 3D plane.

Two 3DHS planes in this video. A 92" Edge and an 89" Slick. Slick is a DA60 on a Proflow can and the 92" Edge is an EME60 on a Proflow can.

Does the 92' Edge look like it is lacking in power?

Both fly really well.
