I keep looking for info on the CMP P-40 in the 40 size plane ..The one with the 54 inch wing span . I cant find much out at all except like CMPs smaller P-40 . A few things like somebodys brothers ,cousins uncle said they flew bad .Or I HEARD the paint comes off some of them .I found on this forum a build of the bigger one . Also found out that on thier smaller Zero the instructions are wroung as far as the CG location .So I guess has anyone out there PERSONALLY bought one built and flown it or is in the middle of a build and can tell me something from first hand knowledge about her ??? They sure do look sharp .. I looked at the H9 P-40s and wasnt impressed .Exposed servos ??? Ive seen a few real P-40s and never saw servos hanging out of the tail .And at almost twice the $$$ of the CMP ??? I was also considering Thier Super chipmunk ..

I have three of the CMPro products but the P40 is not one of them. I have the 40 size Super Chipmunk, 40 Size Staudacher S-300D, and a 50 size Katana. Generally I've been pretty happy with the products and even more happy with the distributor I bought them from (www.jet-hobbies.com).

I built the Super Chipmunk already and had a problem with the landing gear that is wing mounted.

See this thread for more: http://www.rcuniverse.com/forum/m_34...tm.htm#3497302

Other than the LG, it's a nice plane and flys well with an OS 46FXi in it. Fairly simple to put together (took me about 40 hours). I crashed it the other day and it's in a bit of disrepair but I can get it flying again. I'd be careful about getting the Super Chipmunk until the manufacturer beefs up the wing area like I did on the thread. They are supposedly looking into doing this but it'll be a while before the improved version hits the marketplace.

I'm currently in mid-build with the Staudacher S-300D. I'm putting a Saito FA82a 4 stroke in it with JR servos and receiver. I replaced the stock rudder hardware and put in a pull-pull system. This plane is beautifully manufactured and I think it'd be a great choice over the SC. It's a pretty straight forward build and not too expensive. I can't wait to get her in the air.

The Katana 50 is still in the box but I've looked everything over and it looks as nice as the Staudacher.

Generally speaking I think you can't go wrong with CMPro products. They're manufactured nice and very affordable. The SC LG is a design flaw, which they're fixing -- not poor manufacturing. The distributor communicated this directly back to the manufacturer and they were pretty open to the criticism and I believe will fix the problem.

As for the instructions, I have found that they aren't that great for either plane I've built so far and I give them a C+. If you have any building experience at all though you shouldn't have any problem. Just read through carefully.

Good luck.

Thanks ..I did find the post on your Chipmunk before .It looks like a nice plane .To bad about the landing gears thow . I find on most ARFs your wise to change a few things before you fly it . The Chipmunk does fly nice ???
Anybody else know about the P-40 ???

The CG on the CMP P-40 listed in the instruction as 85mm for the leading edge , is wrong. I converted one to electric and found this out the hard way. I emailed raisen tech about this, and to this date no responce. I would not attempt to fly it without calculating the correct CG location, using a CG calculator.

Here's the thread that I made on it:
[link=http://www.rcgroups.com/forums/showthread.php?t=375831]http://www.rcgroups.com/forums/showthread.php?t=375831[/link]

Go to the last pages, in there some one posted a link on a CG calculator program. See if you get the same results as I did. To date no one has verified my calculations, and I pretty much gave up on pursing it any further.

Bobo,

Have you looked into this one thats coming out?

Hi Cubano8 .... Boy she looked real sharp in the pictures you had .Thats what I like about this plane .I think its the best looking one out there . When I started flying I bought a Top Flight one someone had put together . It looked beatiful but being new I was scared to fly her . Then somebody made me an offer on her I couldnt refuse so I sold it ...Wish I hadnt now ..I can now fly the wings off of 2 P-51s I have now and a Texan .Litterally fly the wings off one time .I was getting to brave and was doing a flyby so the wife could tape the plane .I was coming around 25 feet off the deck banked and never noticed the 27 foot tree . OPPS >>>L.O.L... It made a pretty cool video thow .Old Super Tigre screaming away then WHACK SMACK BOOM BANG ..I still jump everytime we watch it ...Anyway . Did you like the way the plane was constructed ?? Everything look glued solid ?? Does it look as nice in person ??
There was a link I found on another site that mentioned your build .He thought that part of your problem was being electric in yours he said with a Fuel powered plane you balance them with the tank empty . Then you add 10oz of fuel to her that adds weight to the nose . With electric you wouldnt have that extra weight .So he sugested moving the CG forward I think 1/2 and adjust from there ..With the tank empty of course .Does this sound reasonable to you ?? He said his flew well ..
I have read a post on the CMP Zero in the same size range and that fellow also said his CG was off to ?? Makes a guy wonder whats up .Maybe CMP should address this ..My Texan was a Ebay Special ..The instruction were terrible ..The CG looked way off to me so I moved it forward about 3/4 of an inch .It was a little nose heavy so I bounced it back a 1/4 and it flys pretty nice .It isnt a CMP I dont think ((( Came in a no name box ..But a real nice plane ))) Had a bunch of World Model parts with it ...
Ive got a OS FS48 looking for a home ..That should power the P-40 pretty well wouldnt you think ?? Think it would have enought room in there with out butchering the Cowling ?? I also have a Super Tigre 45. The 4 stroke would sound nice thow ...
HAPPY HOLIDAYS !!!

Man, that KYOSHO P-40 looks really good.

Trouble is, I think the deal with KYOSHO is that they're not presently being imported and nobody is planning to do so.

bobo,

I've converted a few glow to electric, and used there recommended CG, and they flew great. One of my best conversions was a Sportsman Aviation Corsair, and I used there recommended CG, and she flew very well, with minor trim. With glow yes the CG is going to move forward because of the location of the fuel tank, and the weight of the fuel. But they consider an empty tank scenerio, where you run out of gas and still the plane is flyable.

My biggest concern with a new product that's new is the correct documentations. Most of these planes come from China, and we know the language, and translation thereof can be difficult at times and misspelled, and eventually misprinted. So it is critical to double check there calculations. In this plane, I followed there instructions and it was off by alot.

If you do use a fuel setup with that CG listed of 85mm, when you fill up the tank your CG will be foward, but then when it starts going empty it shifts rearward, and thats when you could probably lose it.

As stated in the other thread, I have nothing against the plane itself, It is a beauty. It's just a pitty that I couldn't enjoy it.

darock,

I went to my LHS yesterday, and they told me that they should have it any day now. So I left them a deposit, and I will call them next week. BTW I ordered the spitfire, and then I will get the P-40.

Cubano 8 Please dont take what I said in the wroung way . I in no way was implying that you goofed up or didnt know what you were doing . In reading your post and seeing your work I could tell you are a fine builder and know your stuff . I was mearly passing on what a guy on a different post had said might have been a factor in your crash . I feel bad for you .It would have been great if it had worked out for you .Not to mention your loss in $$ . And ya your right ..Ive moved a few CGs back and when that tank got low on fuel you knew you were to close to the edge .
My flying budget is limited so when I see a plane I like iI poke and prod around and get all the facts here that I can . So I really apriate you sharing your knowledge with me .I do believe Ill pick one up .Move the CG up 3/4 inch (( You think that would be a good start ??? ))) Then Ill set my duel rates at a bunch of elevator incase its nose heavy ..The CMP is no Top Flight but I wont have a zillion hours of my life invested in it neither and I found one for $149 shipped ...Thats hard to beat .
The Kyosho is decent but I had bad time with one of thier planes and personally think the CMP looks alot more scale .
On my other ?? Do you think a OS fs48 would fly it nice and fit under the cowling with no problems ??
Merry Christmas to All !!!!

1)I have the 73"CMP P40 , very nice plane
2)I have seen , touched and examed the 54" size at the GSP Shop .Very very nice . Based on the young guy at the shop -he siad "there great little planes , keep them light , error to the nose end for CG until you get it correct and you will have zero problem
3)The Kysho P40 will fly (based on proposed weight )like the H9 P40 A SPORT PLANE. Now I am surprised you would even consdier this plane if you are so quick to bash the H9 P40 . With a littel work on the H9 you can put the servos inside, add struts , evev tweek the brown to a more tan .... after all the plane flys like a dream !!!!
4)The CMPs are warbirds, they all average more weight then there ARF competitors so they are more difficult to fly .
If you buy a CMP plane -try AKM modles they are way more reliable them Raidentch and cheaper then GSP on shipping

bobo,

No offense taken, I hope that I have helped people when buying this product to take that matter into consideration 1st. I too love the way it looks. $149.00 is a good price. I paid $199.00 plus shipping and handling, when it 1st came out.

I think the OS 48 will fly it fine. I have a sportsman aviation P-51, similiar size and weight, and it has an evo 46 in it. It goes fast with that setup.

Gentlemen,

The Kyosho .40 warbirds have been out for years. I've got a P-40 that I've been working on and off for about two years now. The problem was that they are known for shedding the horizontal stabs in normal flight. Do a search...... Also, the covering is not monokote type but the older sticky back shelf-paper type stuff that looks like crap after a few minutes in the sun. It does not shrink back well or easily. I doubt any of this has changed but maybe. Tower/Great Planes stopped importing these planes almost immediately due to the many problems/returns they were getting. Its only now that Kyosho has its own USA distribution center are these planes going to start trickling in again. I would like to see a current kit.

The thing is though......;
They fly GREAT! So having said all that I've been tearing off the old covering, rebuilding a new/stronger stab, and am recovering in a more scale color scheme. Whoever said that the CMP is more scale is WRONG! While the Kyosho is no master scale competitor it is a bunch more true to the three views I have than the CMP. The spine on the CMP is not curved enough, The rudder is too short and fat, the cowl is too curved (slopes) on top and bottom, the canopy side window shape are too long and flat on top. While it looks like a P-40 and has a more scale color scheme it's not really as true as the Kyosho.

If you really compare this three view you'll see what I mean.

Mike

I'm just curious to know if the Kyosho P-40 you have is different than this one?

[link=http://www.kyoshoamerica.com/Products/11822B-P40.asp]http://www.kyoshoamerica.com/Products/11822B-P40.asp[/link]

Looks almost like the same plane. The covering looks like plastic film now instead of the shelf paper. However, the colors look even less scale than the previous versions.

Looks like the side windows need some trimming around the frame.

Mike

It looks like Kyosho did the same thing that sportsman avaiation did , they used a color that was good for the spit and just covered the P40 with it .
There is one more option on a very nice P40 and that is VQ .If there still for sale you get one for $199 and this is what you get
1)Flaps , scale tail airfoil , scale rudder , ability to add retracts and contains scale retracts houseing bays , cowl is close to scale and so is canopy .
Tons of rivit detail, panel lines , and fule markings .
The only down side is the shark mouth and most will paint there own like I did , just do a search on RCU , I posted my pics under LDM and there is an entire on line build under Richard L .

Getting back on the track of this thread, has anyone got any feed-back on the 40 size CMP P40. I'm considering one that I saw at my LHS. The finish looked good, with lots of scalish plastic bits to add. I can't say I compared it to a 3 view but if you go by other CMP stuff (particularly the 120 Spitfire) it's probably a bit fat in the fuse. 1st hand feedback on build and flying would be great.

Hmmm I haven't seen any build info on this 40 size either... and it has been a while since any posts about it. What's up?
I'm thinking of doing one... pretty basic with GS40 Supertigre ringed engine..econo all the way.
any Updates?
Nick

Same here. I just ordered one tonight and I was hoping to see some build threads on it. I keep hearing about wrong CG's on CMP planes but I hope they fixed it. That's all I'm worried about.

--------------


LDM, did you use their retracts in your 73" CMP P-40? I bought a set, but haven't looked at them as yet. Can't reach them at the moment. I was curious if anyone has been happy with the retracts. Which engine did you use in yours?


Ed Cregger

I found out the CG is 45mm instead of 85 like the book says. I am trying to decide what motor to put in her. a 72 saito or Tower 46? I will probably get the 46 due to costs. I want to get retracts also but they are out of stock for now.

I had the plane out of the box while the wife was out.(she doesn't know about this plane yet) and my daughter opened the door and startled me. I stepped back with my left foot and crushed the whole left wing![:'(] Now I'm waiting for a new wing to arrive.[&o]

I have built two of the p-40s for warbird racing and have found a couple of problems with them. The CG is too far back,The landing gear is fragile. The mounting blocks need to be reinforced using either landing gear. They only go between 2 ribs and the way the non-retract gear wire goes is back toward the trailing edge. It is best to make these changes before trying to fly it and tearing out the landing gear.The cowl mounting system needs some reinforcing blocks to properly mount the cowl. The covering does look great but makes it difficult to match repairs.

I am speaking of the earlier models, since it was probable ten years when I purchased my CMP P-40 40 size with 54 " wings ( from recent photos from Nitro, the thing hasn't changed any, except the color), then it was offered in a plain silver paint and covering. The aileron servo consisted of the original single one in the middle of the wing, I do not know if that configuration has been changed in the newer versions. I painted mine Camo (Army) green on the upper surfaces and added my own guns, pilot, dash board, and other details. As someone said in a previous letter, keep it Light, this aircraft is all ready heavy for its size...that is why mine was so hard to land, because of the wing loading, its loaded up. Fast speed is the only way to land this thing, so good luck! And the landing blocks do need attention as earlier posted, due to the fast and furious landings ( I luckily made good landings, so I never busted out the blocks, but I foreseen that it would of could of). Mine was a good flyer, but it was quick and snappy, I really had to pay a lot of attention when flying, or she would get away from ya, this is by no means for the average flyer. It is demanding and actually not a lot of fun to fly if you prefer a hands off flying aircraft. To sum it up, this aircraft is Fast & Furious as well as a Beauty if detailed out....
