Almost full line of CMP kits.

Oh Yes the famous AKM SU27 , now that is a plane !!!
If you were a really nice guy you would PM me on a builder that I could pay to be me one , love the kit , love the quality of the lasor cut parts , ect ect . but just dont have the time .
Oh and one more plug for AKM , there prices are great , I drove up to CMP/GSP HQ and paid $279 for the 73" P40 AKMe is selling it for less with shipping at your door

I have a .40 size P51 by AKM and it's the best flying warbird that I have owned. It doesn't look that scale but, it is a great flyer. I did a review of it here on RCU.

what about the Super chipmunks has anybody had experience with them from CMP?

Hellcat56,
I am in Texas as well.. am interested in your FW190 from GSP/CMP ...with a G-26 sounds great... What prop are you running and also do you have any more pictures showing the front of the FW190 with the G26 mounted on it??? How much sticks out and is it mounted inverted or sideways??
Thanks
nemesis4u

I totally enclosed the G 26 inside the cowl, I did open up the vents on the bottom side of the cowl to help cooling-not sure I needed them
I was running aAPC 16-8 believe me with this engine you do not need anything resembling even 1/2 throttle to burn up the sky.
I was going to switch to a 3 bladed prop just for fun.
Attache one front shot you can see the motor neatly tucked in but it is the best shot I have of front on.

I will not buy another product from CMP until they step up and resolve the issues that I had with one of their planes. Below is the email that I sent directly to: [email protected] at CMP. The email was sent yesterday afternoon and so far I have received no response.

Dear Sir/Madam:

A couple of weeks ago I purchased on ebay a Zero .50 that is a CMP product. I assembled and balanced it per the instructions and have had serious problems with how it flew. There are either design flaws in wing incidence with the plane and/or the recommended CG is way off. I just got back from the field from the second flight which ended with the same result as the first. The plane went in after a brief flight which exhibited that the plane was extremely tail heavy. On the first flight I balanced the plane at 95mm from the leading edge of the main wing at the fuse w/o any adjustments for downthrust and left the plane 1-2 ozs. nose heavy. On the second flight, I balanced the plane 5mm closer (90mm from leading edge of main wing at the fuse) to the leading edge of the wing than the shortest distance in the recommended CG range (95-110mm) in the instructions and left it about 1-2 ozs. nose heavy and added 2-3 degrees of downthrust.

This is frustrating and obviously a problem with either of the above. I have built and flown successfully nearly a dozen warbirds to date and I have experienced problems with CG before but, none so bad that I couldn't get the plane in to correct the problems.

I had purchased 2 of these planes and still have 1 in the box which has not been started yet. I was also planning to purchase in the near future an FW190 and a Spitfire but, I will not buy another of your products if you don’t address and resolve the above stated problem. I will wait to review this plane on RCU until you respond and this matter is resolved.

Hi Bob,
Did the kit come in full color box or the plain box of some kind?
Does it look like #1:

or #2

Jackie @ CMP is at Hong Kong. They have a 1/2 day time difference. This is not something CMP can give you a brief response about. I have the larger Zero 120, and it flies great on the instruction CG. Zero's in general will end up tail heavy, due to its short nose moment and long tail moment. You usually have to use a heavier than recommended engine, or add a lot of nose weight. Maybe the smaller CMP warbirds are inherently unstable because of the higher wing loading. Well, make it nose heavier, at about 85 mm to see what it does. Or perhaps your control throws were too large.

Anyway, you can check out my CMP Zero 120 video here:

I have 1 of each but, the one with the problems is like #2. #1 is still in the box unbuilt. What can you tell me about each? The instructions are the same for each with the same recommended CG.

The control throws are/were all at the recommended settings. Again, CMP is in the best position to give the consumer the correct information. It is simply irresponsible for them to promulgate information especially information as critical as CG without conducting extensive testing to insure its' accuracy.

Yours flies great and sounds awesome. I should have just bought that one. I have a new YS 120AC that I could have thrown in it too.

#2 is a CMP kit. #1 is a copy of CMP kit and they do look different, compare fuselage paint (mate to gloss), also covering must be different #2 is no sag or wrinkle and #1 could have both. CMP kits are much better quality over all.
#2 is genuine CMP kit and #1 is what Raidentech sell - copy.

Good luck.

Mine has a YS 120 NC. Your AC will work great.

For reference, my CMP Zero 120's CG is 145 mm. Assuming the proportions are the same, the Zero 50's CG @ 95 mm does not sound out of place. Maybe their Zero 50 is just a squirly flier even at correct CG. I heard their smaller P-40 Warhawk flies pretty bad. The larger one, however, I haven't heard a flight report.

The one that I had the problems with is like the one in your pic. #2. Which is the one that you just stated was a CMP kit. So, it IS CMP's problem. I am now pissed about getting a CMP knock-off plane.

I will probably get that zero or a spit or both if they do something for me to correct the problem. Do you have the spit?

The problems with this one goes way beyond just being a crappy flier. I've had a few of those and just dealt with it without whining but, these problems irritate me so much because of the time factor involved in building/assembling it and to a lesser extent the money involved. To add insult to injury here, I wasted a good new set of Robart pnuematic gear as the nylon housing on both broke. CMP just simply did an irresponsible/lazy job in testing the information and updating whenever possible to keep the consumer informed and protected.

What motor do you have right now on that Zero?

Saito 82a for the second flight.

Are the CMP planes that you have on your site the genuine item or are they knock-offs? I would rather just order from you if they are the real CMP's. I bought a .46 P51 from you that flies great. On this P51 the CG needed slight adjusting but it wasn't a problem to simply land it and make the appropriate adjustments.

Yes, I import them directly from CMP.
Can you confirm that your kit ( the one you have problems with) comes in full color box (pictures on all sides, all perfectly boxed and taped for shipping, internal boxes to hold parts in places) Kind of like this:

Can you post any pictures of your plane?
I just want to be sure that your kit is a CMP kit.
Thank you.

Is this what you got from user: uce-techcom ?
This is not CMP kit, they use CMP box labels but kit is not CMP.

I am sure after reading your post about the differences that the plane that I had the problems with is in fact a CMP plane whereas the plane still in the box is obviously a knock-off. I'll look for the link to another post where I posted numerous pictures during the build and first repairs. The CMP plane is of much higher quality and much greater detail.

Are ALL of the Raidentech kits knock-offs of CMP models? I intend to purchase the F6F Hellcat next month, and they were recommended to me. I wasn't aware of that, but I'll stay away from them if that's the case.

Do you have a CMP F6F?

Hi Mike,
I can not say for sure if Raidentech has CMP kits or not.
BUT, I would think that they are not CMP kits.
Their supplier (I think) is http://www.fly-model.com/
They are also my supplier for allot of kits, BUT our CMP kits are direct from CMP.
I actually have two versions of F6F one is CMP one is a copy same as Raidentech. This is how I know the deference.

AK: Will CMP stand behind their product or will they just jerk me around?
