Try the 2409-12:; you will thank me forever !!!

The motors coast less than $20, wears like iron and goes like hell ! (On the P-40).

In this case, the motor is shown on a Corsair. Modifications to the mounting stick must be made for the P-40.

A speed controller of 25 amps (Minimum) should be used.

[B]Warning !! -- Do not cut the motor shaft off --[B]

Pete: Will the motor be able to perform on the P-40? The P-40s wingspan is 5" more and weighs at least 10 ozs more than the smaller Corsair. Traditional GWS powertrains may not be applicable with the new larger GWS planes.

I am 78 years old. Have been flying RC since the beginning. I have a beautiful VCR: My wife can't get the VCR focused and I am having trouble finding someone to take the P-40 video smokin' across the field five feet off the ground whilst upside - down.

What, oh what does one do ????[IMG]

RCDad,

Here is a photo of my P 40 that I have not gotten the nerve to maiden yet

It is really pretty sad. This plane has been on my table completed since the end of May.

The P 40 ended up being pretty nose heavy with the Himax 3510 motor and 3" spinner. I had to hack the plane a bit and push the 3 cell battery back to the pilot's seat. I also added retracts (something I never did before, but always wanted to try). I really like this P 40, I hope GWS reproduces all of the older warbirds in this size of a plane.

I am currently working on a second P 40 to keep in my trunk for quick flights after work. It will be built from salvaged parts from other less fortunate GWS planes.

PuddleJumper,

mine also ended up nose heavy, even without the dubro spinner (only took some photos and removed it before flight) and I had to put some weight at the tail.

Have did you hack the battery compartment? Is it a clean job? Can you post any pictures?

You see the cockpit in mine is occupied


Thanks

Glaros,

I was fortunate enough that a friend of mine built his P 40 with a very similar setup first. He warned me not to put the canopy on until the battery was moved back far enough to get the C.G. right. I used a utility knife to cut a hole (just large enought for the battery to fit through) from the cockpit forward to the battery compartment. The battery pack is laying on the pilot's seat and pushed back all the way to the back of the seat. I also used a Dubro 3" spinner. It is too heavy.

On my second P 40 I used a Great Planes 3" spinner with the aluminum back plate. The second P 40 still ended up nose heavy and I had to push the battery back again. This time I used a dremel tool instead of the utility knife to remove the foam.

If I ever build another P 40, I will cut the battery compartment out before I glue the two halves together.

This is weird guys. I used a DuBro 3" spinner on a Scorpion 2215 outrunner, and 3S 2200 lipo. My CG was at 48mm and it flew great. I did not have to mod the battery compartment at all. In fact, I had later moved the CG back to the recommended 55mm, and it flew worse so I moved it back. I'm surprised to hear you are having CG problems. How big are your packs?

Mine is a 1700mAh 3cell lipo pack. Would like to use 2200mAh but it would make it even worse...
