I know this plane is a little old, but I aquired one just recently. Thought I could put a G-23 on it. Have second thoughts. I think it might be to heavy!? Anyone out there can help me. If the g-23 is to heavy I think I'm going with a supertigre 90. Please advise! Thanks, Mike Geracci

Mike,

Not only is the plane too heavy, the cowl is not wide enough for the motor to be concealed with doing some serious butchering to it. Try looking at one of the physically smaller Evolution gas motors, like a 35 for it since the motor is smaller than the Zenoah.

Most any gas motor would be too heavy and not fit under the cowl. I have a Saito 150 on my Ryan and it flies it very well. You'll probably end up putting a lot of lead in the tail if you use a gasser.

I have the GP Ryan STA. I'm using an OS 91FS. Flies very scale like, with big round loops. It also does some of the nicest slow rolls you could ask for, you just have to feed a little up and rudder when doing them. The plane is a ***** cat to fly. It doesn't have unlimited vertical but neither did the real plane. I ditched the wire struts and installed the Robart Struts, which makes ground handling a breeze. In fact, I love doing touch and go's with it. I land the plane with just a tick above idle as I past the threshold of the runway I touch down and then keep the tail up until I reach the other end of the runway where I add a little juice and she is airborne, ready to do it again. Most of my flying is at 1/2 throttle unless I want to do a wing over then I use full power into the climb. The STA on a clear blue sky stands out and looks really nice. I wish GP didn’t discontinue the plane.

Thanks so much for getting back! I just wanted to stay with gas. I will get into glow fuel one again! Mike Geracci

Thanks so very much for geting back! I've been flying a number of years but I just wanted to stay all gas! I'm going to glow fuel once again! The only thing is that I just hate to buy an OS91. Do you think a supertigre 90 would work. I had a supertigre way back when they where made in italy! Ran great! What do you think. Should I bite the bullet and get the OS? Did you get struts from Robart. They have to be unique to this aircraft. Let me know. Thanks again!

i have a ryan sta with a ys120sc on it and its unlimited performance and its a blast to fly

I have an STM that I stripped for a more scale looking recover in solartex and chrome Ultracote or Monokote. It's still unfinished becasue I had to move in the middle of it. First, I was looking at the Evolution 26gt but now I'm considering going electric because there are really affordable motors and ESCs coming out now. Affordable like $100 for the motor AND ESC! Batteries are getting cheap too. Probably another $200 for the batteries that will fly it scale for 15 minutes with a 15 minute recharge. This prospect is mighty tempting to me and actually cheaper that both gas and glow.

Thanks for getting back. I guess I'll have to bite the bullet and go back to glow fuel. Thanks again. Mike Geracci

Good point! However, I know nothing about electrics, and really not interested as yet. That's a whole knew world. Thanks for getting back. Really a bunch of great guys out there. This is the first time I used this forum and I'm really pleased. Hope I can help someone out in the future!! Thanks again, Mike Geracci

Yes getting started in electrics is intimidating. I have 3 electrics now and several glow models. I find myself flying the electrics and dusting the glow airplanes. Electrics are just so much easier to care for and operate. The electric planes stay in a NEW condition as long as you don't crash. No wear and tear and never dirty. I am no electrician either but I am a great imatator of others and haven't had any problems getting great performance. Now that the larger scales are getting cheaper to equip I just can't see myself mounting another glow engine on an airplane.

Wow, That's pretty good! I just don't like the idea of charging and waiting on batteries!
Did that with electric cars! Pain in the a__! Oh well, each to his own. Going to hit the sack for now. Good talking with ya! Mike Geracci

I've had one sitting in my workshop for a while now too, I put a G-26 up front, and I can tell you after about 20 flights it is definatly not too heavy!
The plane flys awesome with the gasser up front. I used one of Bennets headers (fits in the cowl with only one cut for exaust exit) I opened the right side for the carb. The plane has more than enough wing to carry the weight. I mounted my battery aft of the rudder and elevator servos. It balances very nicely.
The G-23 will need firewall standoffs of about 7/8 of an inch. No problem with engine cooling. Give it a try.... you won't be sorry

There been one in my shop for the last 6 years. I have a Enya-155 & a G-20 that may work. If I never woun't to do something , this is it

I fly mine on a G 26 works fine, Very scale flying....Good Luck
