Just some of my experiences with gas; I wanted to get into gas for two reasons; Economy and cleanliness. My original goal was a small plane ,(60 to 90 size) on gas. I took the plunge; converted two homelite 25 ccs . one on a H9 ultra stick. One on a scratch built). Flew well. I Forgot a Dynaflite PT19. It Flew O.K.. too heavy. Obviously I am not interested in flying 200 M.P.H. I am not interested in flying straight up 500 ft. in 1.2 seconds. Just normal, sport Sunday type flying. Then I put a Homelite 25 on a Sig 4 Star 120. It flies great! A G26 would fly it faster and more arobatically, butt......I am now on the 5th flight with a FPE 1.3 on a 4 star 60. I love it. Typical 4 star charactistics.. Again; not a speed demon, but a nice easy flying plane that is cheap to fly. Feels about like a 90 4 stroke on it. I had a G26 and it is naturally a lot more power, but more money. A friend is currently building a 4 Star 60 with a RCIGNITIONS modified G23. It will be a great combo, I'm sure. My only reason for this information is to let anyone know, who is thinking about gas; GO FOR IT! It's clean; cheap; fun; easy. If all you are interested in is go fast straight up, and have a lot of money, then buy a large glow two stroke and have a ball. Oh there are fast gassers too, but we are talking bigger and more money. It all boils down to what you want. I have a feeling there are a lot of people out there who just want to have fun flying and do it reasonably. GAS IS THE WAY. Some people say you can't put gas on a small plane. Hmmmmm O.K., I guess I shoulden't have done it.

Well, Hubbajer, I have an Evo 26 on the way and am putting it in my Funtana 90. Already have an FPE 2.4 in my Sig Extra and it flies wonderful.
But, take a look at the Evo gas burners and the Roto's as well. They are very light compared to the usual gas engines, roughly 20 ounces lighter. This means they can be installed and flown in some of the 3D aircraft such as the Funtana and perhaps QQ's 72" span Yak 54.
I think bringing these light but powerful gas burners is going to change things a lot and suspect there will be aircraft designed just for them.
The Evo 26 is in the same weight range as the Saito 150 I had originally installed in the Funtana 90. And, it will be cleaner, cheaper to operate and just as strong for hovering.
You're right. This is the way to go. I've always hated having to lug all that stuff in a field box for glow engines. Now, just the airplane, some gas and the TX. And, maybe a screwdriver in my pocket.

VERY roughly lighter...20 oz less than a converted G26 would be a 20 oz engine...

Just checked, evo 26-32.8oz I aSSume that is with out igniton etc. My g26 converted with ignition is 40 oz I would call it even. Now it's time for me too start looking for another plane to put it in.
