Default super chipmunk 120

Im buying a GMS 120 from a guy for a real good price, so iv been searching for a 120 sized plane to put it in. Iv got my eye on the CMP 120 super chipmunk from nitroplanes, heres the link to the plane http://www.nitroplanes.com/gisccmpsucha.html It says it requires a 90 to 108 2c. I cant find a thread on this model anywhere in RCU. Just wandering if any of you guys know anything about the quality of this plane. And also even though it recomends a 90 to 108, would the GMS 120 be to much engine? Thanks........... Tony

Ha! This is funny because I just bought a GMS also for a real good deal and I am looking for a plane to put it on. I just came from looking at the chipmunk myself- good looking airplane, but I'm leaning towards the seagull yak for my 1.20.
Good luck with yours!

What kind of experiance do you have with engine to plane ratio? Think the 120 would be to much?

I think the 120 would be a good match for that plane. If it weren't for the fact that I really like the seagull yak- this would probably be the plane I would buy for my 120.

Big price difference, but the GP Super Chipmunk is much more scale, looks better, larger wing, and could handle the 1.20 much better than the nitroplane model. Of course, it's a lot more money as well.

I've flown my several times this past summer. It flew with a Enya 1.55R 4-stroke. With this set up I cut a hatch in the rear of the plane and put the battery (3000 NiMH) alone with several oz. of lead to balance the plane. It does fly nice, but BEWARE, because the plywood that holds the landing gear in the wings will crack. Plus they are not glued in very well.
The first time I replaced one I was able to pull out the plywood with a pair of pliers. One yank and it just popped out. I have since replaced them both. First the left one let go, took the plane home repaired it. The next weekend the right side let go. Several weeks later back to the field and the planes flys nice.
Now with winter I'am taking out the Enya and putting in a Super Tiger 2300 2-stroke, just to see if I can get some of the weight out of the backend. I had a Goldberg Super Chipmonk with a Super Tiger .90 and loved it. I wish that the CMP Chipmonk flew as good, but it doesn't.

That is interesting, I reread my instructions and they dont say anything about having to add weight up front. Even balanced it with a Great Planes balance stand. It didnt seem to fly tail heavy when it was flying, so I'am guessing I got it right.

tailspin, you must be referring to the GP super chipmunk - it requires weight. This thread isn't about them...

Hey all. I have the CMP chipmunk 120 with an ASP 120 four stroke in it . I have to say that it is the perfect match for weight and performance. Plenty of reserve power yet not over kill. With a 6 volt 1200ma battery mounted right aft of the servo tray, behind the wing mount, it balances perfect with neutral elevator trim. This is typically further forward on cg than CMP calls for as they usually post way aft cg's. Only advice would be to make very sure you install the gear tight and facing forward. This plane flys like a charm. Goes where ever you point it and lands so slow and soft. Flaps make it really sweet. Great plane for the price!!

A lot of us installed gassers ranging from 26 - 40cc in the GP models. Should be no problem and helps get the weight forward.
