As usual I'm a late starter. I managed to find this plane at Chief Aircraft (they had all of one in stock, no where else I called had any at all and had no idea if they would be getting any more....is this plane discontinued?...guy at Horizon I talked to seemed to think so). I wanted a easy flying P40 (as opposed to the great looking CMP 60 size Curtiss P40 Lawn Dart, rare model...get um while they last), about the only allied plane I like...I usually go for the German birds. Anyway, the firewall will be glassed for strength to halt separations (Saito 100). My other concerns are the stories of stabilizers snapping and the plane doing a CMP P40 impression. Can anyone give any advice on beefing this area up to avoid this problem?, light glass and recover maybe? I'd like to have this plane around for a long time. I've already dodged a bullet and got an undamaged box from the brown truck today, I paid $115 for next day, figured the shortest amount of time they had it in thier possession the less they'd be sitting on it to eat lunch or playing soccer with it in the warehouse wearing steel toe boots. Opened the box....pristeen, I wept (my wife, however, did not when she saw the outer carton and stared at me with her hand on her hip and said, "another one?" , of course I also credit Chief Aircraft for properly labeling and packaging it.

If you avoid flying the plane like a 3D machine I don't think you will need to beef up the stab.

Use the soldering iron method to remove the covering in the area where you will be bonding it to the fuselage.
That way you avoid scoring the balsa wood.

I flew the crap out of my H9 P-40 and the only reason it crashed was due to ME being stupid.
I tried a split ess from too low and ended up leveling out at -5 feet of altitude.

If you look earlier in this thread you will find a video I posted of my H9 P-40. Notice that the way I flew it in that video is how I flew it till the day I crashed it, and it held up just fine.

I agree with Tommy Gun. I've flown mine like crazy too with a Saito 100, used the soldering iron method for the rear feathers and had absolutely no problems with about 75 flights on mine now. Unfortunately my Saito ate a exhaust valve, but I managed to make it back to the runway (barely!) and saved her. Now, do I replace the 100 with the 125a or maybe a YS 110? Hmmm, choices, choices.

Hi fellas. I just bought one of the only H9 p-40's I could find, and I had a few questions for some of you experienced flyers. I have been flying a parkzone p-51 for a year and I decided to take a step up to the larger scale. I was just wondering how big a change it would be flying this larger scale. Is it something that I should have a more experienced flyer take up to trim out or will it be fairly comparable in handling to my smaller warbird? Also, I bought the evolution .61 - does anyone foresee a problem with this smaller engine powering the plane? Thanks for the advice.

In reference to your engine question, The .61 will be fine for flying this plane, the H9 P40 is quite light. Actually if you like scale takeoffs you'll probably have to fight to keep it on the ground, these planes like being off the ground. As far as flying the larger plane as compared to your Parkzone, larger planes are easier to fly. If you can fly the Parkzone successfully I have no doubt you'll be absolutely fine, still, everyone has the maiden jitters. You can have an experienced pilot take it up and trim it if the jitters get the best of you, personally I've never almost crashed because of trim, I just eyeball it on the ground, I've never needed more than 2 or 3 clicks to trim out a plane. Good luck with your plane, let us know how she, and you, do!

I bought the Evo 61 for my warhawk as well putting together this week. This is my first nitro plane,i am sure the guys at the field will give me all the help I need.

thanks for the information. I am glad to hear that these planes fly well. I will hopefully start building this weekend and get to flying sometime in April. In reading all of the posts in this forum, I see that many people say that the center of gravity should be around 3-1/2 to 3-3/4. Is there any reason I shouldn't set the CG around these instead of the recommended 3 in the instructions?

when balancing the P-40 I went with 3 3/8 and it was still a little tippy wanting to nose over a bit once I got used to it landings are fine,in the air the plane is just great fun to fly and solid.
mine is powered by a OS91 theres plenty of power in that range of engine,and it balanced right where I wanted it without any extra lead in the nose, with the evo you might have to move some weight forward to get the right balance.

Help!!!!

I'm building my H-9 P-40 and need a decent pilot for it. I went to Tower w/o luck. Remember, it must be a WW2 american pilot bust. If you know any please let me know.

Thanks!!!!

I got a couple of these for my 2 H-9 birds there sold out but you might want to check with nitromodels to see if there going to get some more there pretty good looking for the price.
http://www.nitroplanes.com/rcmodelpilot5.html I did repaint mine for each plane so they looked better just some minor stuff

So I picked an ebay special $175 H9 P-40 and $80 Evolution 60.

I love my PTS Mustang (my first Nitro plane); I fly her fast with a 10x8. I also picked up a cheap F22 PTS, I put a .54 and 10x8 prop on her and she fly pretty good as well.

I love P-40s like most of you and have been keeping my eyes peeled for a good deal, I've had success with H9 so I bought this kit. I've started building and am at a point now where I need to make some decisions.
How should I mount the Evo .60? I mounted it as per the 2-cycle instructions but with it mounted upside down it appears that I will have to cut out a profile of the big muffler out of the cowl. I guess I could make her ugly from one side but I really don't want to. Can I use the same firewall holes and flip the motor sideways with the head possibly sticking out the cowl slightly but with the huge muffler fitting underneath and in the cowl? Are there any cool mufflers or adapters I could use? ANY 2- Stroke P-40 Pictures would be highly usefull, I would love to see how anyone has mounted their 2-stroke!

Second question, can I put the standard JR BB Servos in the tail as per the instructions while mounting the battery under the fuel tank against the fire wall? The Evo .61 with muffler is 25.44oz; a Saito 91/100 is about 20oz.

I have already mounted the horizontal stab, should I cut it out and put some carbon fiber through it? If I modify it, it will look pretty bad I'm sure. Has anyone flown their P-40 at about 7.5 pounds and actually flown it like a sport plane (full throttle dives, snap rolls), without the horizontal stab ripping in half?

My questions are:
1. How should I mount the Evo .61 for the least amount of cowl distruction, (please refrain from saying that I should have bought a 4-stroke)?

2. Should I mount the servos in the tail? If not, how do I drill guides for the push roads through the fuse and what is a slick way to exit the rear fuse with push rods?

3. If the rear horizontal stab seems rigid should I modify it to prevent inflight failure?

Thank you!

brady...you could try looking for a "Pitts" style muffler for your Evo...
They are available for most engines, and I think I saw one somewhere (try a search ) for the Evo .61?
There are generally 2 types...for either side mounted or inverted engines.

You could strip the covering from just the bottom of the stab and sheet it with 1/32" ply and that would greatly increase the tortional rigidity and over-all strength. (that's what I did with mine, after it was installed ) Glue it on with yellow furniture glue (Titebond, Elmers cabinet makers glue, etc. ) or Gorilla glue.
