Some people with twin envy are willing to spend the same $ on a baby twin instead of just getting a decent 100cc.

The twins have better low and mid range throttle response and run smooth. The DA-70 is 7 ounces more than the 60 and performs very close to the DA-60/RE2 which is actually heavier than the 70 with jtecs. Those EME-70 numbers seem close to what I was getting on the 25x8W before adding pipes.

There is an EME vid also showing tach numbers on std exhaust but it does not show prop size.
25x8w @6800 on a new engine is very good. It is the electric start feature that I really like. Wanting to do a decathlon or christen eagle for some scale aerobatics and then just hang it on the prop for fun. I think this engine will do nicely.

there has always been a need of a good 60-70 twin for the 30% planes.
myself I like the way a 30% plane responds,verses a 35%.
I just don't see a advantage, or have a need to go to a 35%
so with all of the new twins out it is just that much better.


nice to see some reports on the EME70 now.

35% are bus like and slow to respond compared to a 30% or even a 25%. I prefer the 25% and 30% sizes. They're cost effective and a lot of fun. Bigger is just a plain to store, transport and maintain for a lot higher outlay and they're a lot less fun. Hence a good 40cctwin for 25% ers and 60-70cc twins for 30% is a really nice option. Weight of the twins doesn't bother me since I love MVVS engines and they're pretty weighty

We have flown a eme70 about 14 times now on a 3dhs yak. The power is good, tachs out very good. It does not have the same quick spool up of the gp 61 on bender pipes on that same prop so the pull out of hover is a little slower. I think that motor will be crazy on properly sized pipe but then we add more weight
