tiger moth 1.20
 

I just had a friend give me a super tiger 2300 it is a 2 stroke 1.41.It weighs 32oz.without muffler Will this be ok in the tiger moth or is it too heavy.It is about 3oz heavier than the engine I was going to use but I like to overpower a little because it can get you out of trouble sometimes.

I'm going to put a 3.5# Ryobi 31 gasser in one, so I wouldn't worry at all. Your motor should give great performance, but keep in mind the full scale plane was slow and didn't have a high roll rate.

Hey Wildeone,

Did you get your Tiger Moth with Ryobi done? I have one done that way. Flies quite nicely. My Ryobi is running on what we call "Gas/Glow" (without an ignition system) so it is a light one. I had to add a couple of ounces of lead weight to the engine to get the plane to balance as specified. I also very carefully cut ailerons out of the top wing and made it a four aileron setup. Worked REALLY nice and gives a much better roll rate. I know it's not scale, but that doesn't bother me. The only problem encountered was that I couldn't find covering to match; anywhere. I just used a yellow that was close and called it good.

It flew very scale-like with the Ryobi. I only have one outing with it and the Ryobi was just breaking in. I've since put more time on the Ryobi and it's gained some power. It's turning an 18 x 6 prop at about 7300, or a 16 x 8 at 7500. It didn't have the excess of power I liked when I flew it, but it should be better now that I've put some more breakin time on the engine. Some guys claim more power with their Ryobis than I seem to be getting. I may try an 18 x 8 prop to see how that works as that's about the size most use on this engine.

How's yours doing?

Thanks,

Sad to say, mine is still in the box. I have a big SPAD with a 19CC leaf blower motor that is almost ready to fly, then I will build the TM 120. Glad to hear your's is going well.

Well, it's a nice looking plane once it's all together, and an impressive size for a biplane. I like mine...

Where the main upper wing struts attach to the fuselage is a bit weak. I installed my wood screws with epoxy to help. A better solution would be bolts with flat washers and nuts if you can do it. I can't really remember any other specific issues other than the horrible instructions. Hell of a good price though...
