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......

Default 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.

I hope they will work for you Steve. The antenna metal is a very thin tube and not piano wire. They look very nice. I plan on making a groove in mine to install an "O" ring to hold them on.

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!

Reost 1207 . With the wing incidence changed, where would you recommend the new CG? I will be changing mine as per your recommendation, just need to know about the CH. Thank you in advance.

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

Hi Minare

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.

The top flite arf cowl fits very well. It is a little large on the bottom but after you dremel out the hole for the engine on the bottom it comes together very nice. The windows do not fit, and the struts need a bit of modification to fit.

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 CG is measured near the fuselage, not the tips.

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...

Unfortunately, I still cannot understand why so big difference between 70~80mm cg ( advised on this forum ) and 120mm ( found with theoritical calculation )

seems that cg must be at 25% of wing wide instead of 30%
