It was the wood. Can't wait to get another 88 for my next imac bird. Why mess with stuff that works well for competition. Ps can't get any better than limitless aero for their customer service after the sale.

Would a Vess 27 B prop be too much for my GP 88?

Hi Brian, For the DA-85 and or the GP-88 (Standard) a 26X10, 27X10TH or the Vess 27A will work great.
The GP-88EVO will rock the 27X10 or the Vess 27B as it has about 300 more rpm. Now this is based on a Dump Muffler or Canister, A pipe is a whole different world.

Both engines like the xoar best but noise is a concern when going to full throttle. I usually fly half throttle and only use full throttle on uplines. The menz was quieter but had less verticle power. Mezlik was probably in between the two. The evo88 prop for prop has 10-15% more power. Love the engines. Toby
Toby, what kinda rpm do you get on your 88 evo on the xoar 27x10?

Mac, I rarely tach engines. My best way to evaluate performance is come to a hover, then punch out at full throttle and be able to do 3 snaps separated by 50' per snap. I want to be constantly increasing speed. I find this a valid way to see if you have enough power to fly imac sequence in 20+ mph winds. If I would estimate it is pushing 7000rpm. I have a standard 88 in a h9 sukhoi and several people thought I was flying a 40% it presented so well at the nats. Now if my flying was as good as the plane. ��

The 88 is one of my favorite all around engines.

Ive had some real aggravating instances with mine. Kole its the one I sent to awhile back because of the crank pushed back... I got some issues with the transition that i really cant figure out I thought i was pretty good at tuning an engine but i cant figure this one out. When i go from idle to full throttle with it it'll either die or almost die everytime unless i have the high needle extremely rich.(misses often at full throttle rich, like rich rich) and i know it seems like the answer would be in the low needle but ive tried that and the low needle seems to have no bearing on the problem... I think i have to run the high over 2 out before it'll stuart running even tho it will still hesitate and i run my low needle about 1 3/8 or so.... Dont think it's setup I just replaced it with gp 61 on a 91 extra and the 61 runs awesome! I'm gonna put that 88 on a test stand and see if i can fiddle with it some more...
