As ugly as they are, I've decided to get another profile to help improve my 3D skills. Been flying a profile on AFPD and it's crazy the way that thing handles.

I've decided to get an OMP plane, due to their reputation, and they have ARFs. Got too many other projects to screw with building a kit right now.

I'm at high altitude, so the 46-50 size engines aren't going to give good performance on a 4-5 pound plane. I loose about 20% power up here. I need to know whats the biggest 2-stroke anyone has stuffed into one of the OMP ARFs. What mods, if any, did you have to do in order to get the motor in there?

I really wanted to use a TH .75. My favorite engine, but I don't think I can stuff it in there without doing major mods to the plane.

Whats the most powerfull engine that can be stuffed into these planes?

Thanks

Don't have one but, guys have put .90 size 2 strokes on the 40 sized yak and edge.

Now THAT, I'd like to hear about!!

I guess if they can put a .90 in it--I can use my .75

Would like to see pics of the install and any comments from people who've done this.

Thanks

You NEED to overpower a profile. That's what it's all about!



85" span Ultimate. ZDZ 120 for power. EDIT- it's sitting next to a 1/4 scale, Midwest Giles 202.

I know it. There's no point in putting a 46 or 50 on a 4-5 pound profile at this altitude. It'll have almost enough power to fly like a trainer.

I like the Giles. I have one in the shop. Have never finished it. It needs at least 1.50 for sport flying at this altitude, and I don't use glow engines that big anymore. I'm either flying gasoline, or glow .75 and under. I'm not buying another glow engine over .75 in size, so the MW Giles will probably never get finished.

I guess I'll order the OMP and slap the .75 on it. If they really only weigh 4 or 5 pounds--it'll be just right with this engine.

Thanks
