The 61/123 have only been around since summer now and they are just now starting to get out there but we have had our 88/176cc engines out for 2 years now and they have really proven them selfs, Brian flew my prototype and Joe Nall this year and pretty sure he liked the power.
I am send one to Gyro to do a full review on hopefully this week but they sell faster usually then i can get them in.

Ive got one on the way, very excited to get it and beat it up in my EF 300. After seeing Gary's run and RIP a 24/9 prop, not even broke in yet, I had to have one. The numbers I'm reading online from posts are showing this engine to have more power then the OTHER brands Cant wait !!!

Going to take it out this weekend with the 24x10 and lean her a little. Over a gallon through, time to set the engine free! I bet once I get the mixture right, we break 6700 on the 24x10 rpm.

You want to join us?

I'm getting some reports of guys swinging a 24x10 standard Mejzlik on stock mufflers, and a decent mid-range pull on this engine. As I mentioned on the EME thread, a lot of air seems to have come out of the EME-60 balloon. I was wondering how this GP61 has lasted with the 3D pilots since its release, and if it can really swing at least a 24A Vess or 24x9 Falcon, to at least 6700 on stock, or a 24x10TH to at lease 6800.
