I have the right main gear. The left is broken. It is in pretty good shape. I also have brand new, unused wheel pants.
Not sure what the postage to France would be......

CMP/Nitroplanes 1.20 or 1.40 Cessna 182
Big alert here. Before you fly Check your wing incidence relative to the horizontal stabilizer when it is neutral ! The Top Flite kit is about +.25 degrees positive. My CMPro/Nitroplanes had +5 degrees ! ! ! I have had two of them and they have BOTH had +5 degrees. This renders the plane virtually unfliable. I had to raise the trailing edge by 5/8 inch to get it close to 1/2 degree positive. I did that by laminating balsa and very thin lite ply in a horshoe shape and the plane became a BIG trainer.
Other posts have siad it was a CG problem and moved theirs WAY forward but that is wrong. With this solution it is one of the nicest fliers I have ever owned..... until..... radio failure. Rx died.

The Build - Took way too long and required way too many modifications - Done!
The Maiden Flight - finally after all this messing around - Done!
Thanks to all the preceding build notes and modification ideas, and most importantly the configuration notes from flyers, the first 5 flights went flawlessly!
Definitely a very solid Scale Flyer. It looks and flies like it should.
Thank You All!

hi
Someone already flew to the modification of the angle of incidence?
which is used CG?
I already change the angle but I need to test in flight.
any information is appreciated.

Hey Fabian,
the measure is 10 cm from Leading edge (about 7 cm if you want to measure on the center section that has not the LE, trim)
i fly with about 0.5 deg, and it feels great, especially in low speed with flaps and landings.
warm greetings from Israel

Thanks you very much for bring me measures ..when you have some time .can you show some photos from the modification and how much you have elevated the TE to obtain 0,5 degrees?
greetings!

Resurrection time!
I needed to rebuild my Cessna. This time it is going on floats. Hangar 9 just came out with 1/5 scale floats and the are due I think in March or April. My cowl was trashed due to a couple of different engines I tried with this plane. I bought a new cowl from Tower, the one that fits the Top flight arf. It fits! a little large on the diameter but when I cut out the bottom for the engine it will squeeze to fit just fine! I bought a new DLE 35ra, yes, a 35! I need the extra power because of the extra weight of the floats. I am hoping to get her back in the air soon.

I stripped the wings and wingtips. The wingtip light lenses were hammered. I made a mold and created new ones. Not the greatest but better than the old ones. I painted the wingtips today, came out very nice. I will try to get some pictures soon of my re-build. Oh, the top flight cowl works but is a little too wide on the bottom. After I install the engine and cut the hole for it, the cowl will snug up just fine. Covering the wings today.

I just got my 182 down out of the attic after about 4 years of sitting. For the most part everything looks to be in good shape, but I do need a new cowl if anybody has one laying around they want to part with.

Hello, I am preparing 1st flight of my 2m10 Cmpro Cessna
I still have a doubt with cg value...
From where do you take the dimension ?
I calculated cg with software and found 120mm !!!
Very far from suggested 70 or 80mm
80mm is applied on the middle wing ( bolted on the fuselage ) or in the side wing
There is 30mm between the middle and side wing starting edge
Thanks

The lower pic would be correct though i am not sure why you have two different measurements (80 vs. 110 mm).
Whatever the manual specifies, that's the one to go by...
Usually the designers of a plane know a lot more then we do and have a reason to spec it at a specific location.
However, once you put some flight time on the plane, you may want to move it to to better suite your flying style.
As the saying goes, a nose heavy plane will fly again while a tail heavy plane will only fly once (or something like that).

I misunderstood when you said to do measurement on fuselage side and not tips side
As you can see, central part of the wing is 30mm shorter than the 2 wings
So I understood that you told me to do measurement on central wing part
Finally, you and me are doing measurement following same way
I cannot mind that everybody do the same measurement way because on this forum, cg is around 70~80mm but sofware I used gave me 120mm
This software is very accurate and usually give the correct cg
50mm is a big difference !?!
I think that you don't have this plane, Bill ?
If I can have answer from people who have this plane, it will be very useful because I don't have the manual and to be honest, if I had this manual, I would never follow it
I had a glider from this factory ( cmpro ) and cg indication was very bad

Actually, i do own the model, its still sitting its box buried with other planes i haven't gotten to yet.
Every R/C plane i have ever owned (kit or ARF) always say to measure the CG where the wing meets the fuselage, and i have been flying since 1988...
