Just saw this ESC on Hobby King:
TowerPro H40A Brushless Speed Controller

Doesn't look like a bad deal for $10 bucks. The onboard BEC looks like it might be a bit wimpy but I tend to use external BEC's anyway. I like the idea of the external heat sink.

Even if you use an external BEC the cost is still under $20 bucks.

Not yet, the weather keeps ruining my plans . Just when the winds are low enough, it starts thunderstorming. When the storms stop, it gets windy. That's Kansas for ya.

Worry not, today I believe is the day. It's 75 degrees out, clear skies, and wind 3-5 mph. I will be leaving for the "field" within the hour. (Taking my EDF F-15 also). I don't know if my wife will take any pictures but I will post flight report tonight.

The good, the bad, and the ugly...

I maidened the GWS P-40 today and I have to say that once this baby gets its airspeed up it likes to go. The stock motor really performed better than I expected and man does it look big in the air. My Scorpio FW-190 has the same wingspan and does not seem to have anywhere near the presence this plane does. I had a bit of time getting down on the deck to land because it just wanted to stay in the air. It took a few clicks of right aileron and a few clicks of down trim for level flight and it cruised just fine. Like I said, I needed to set up my landing a ways out as even with power nearly off it just chewed up a lot of ground to settle in to the ground. First flight was only about 5 minutes. That was the good.

The Bad: After flying my F-15 around the patch I decided to throw a second battery in the P-40 and give it another go. I was feeling good and even though deep down I felt I was pushing my luck I thought might as well, I didn't come out here to look at it. After a successful range and flight control check, I lined up on the runway, throttled forward, steered straight, ever so slowly eased in the elevator and the plane's nose popped striaght up, then subsequent nose over with enough altitude to level out, but no airspeed then came the tip stall but I recover. Damed if I did. So mad because I leveled it out and reduced power for an emergency ditch in the grass. The worst that would have happened is a nose over in about ankle high grass. That's when it hit a !!! PVC pipe sticking about a foot and half out of the ground!

The Ugly:...the pictures say it all. It doesn't look too bad to me. It should be repairable right guys? Please someone say yes, because the wife was there when it happend and delcared I can't buy a replacement and need to find a cheaper hobby. I suggested beer drinking and shooting pool, but I think you all know how that must have went over .

looks like she should fix up just fine if you have most of the pieces and if you dont go find a cooler or some packing foam to fit in. i prefer an old gws plane that is beyond fixing as this foam is a lot better. anyways i have fixed worse and she flew just fine. good luck. andrew k....

hi guys, I bought myself a p40 a few days ago ... this is my second plane my first is a 1300w funjet

After reading the last 20 pages or so of this thread I decided to buy the Tower Pro 2409-12t motor but I have been scratching my head over this one as it seems the shaft is sticking out the wrong way. It comes out of the same side where I need to mount the motor! I have tried loosening the grub screws to see if I could slide the shaft through so it comes out the other side but it wont move easily. Do I need to mount this motor the other way or should the shaft be turned around/slid though?

Thanks guys!

Are there holes on the other side of the motor too? You may need to buy a different motor mount that screws directly onto the bell.

Here is one of mine that has the motor mount coming out of the same side as yours. There are screws to mount a prop shaft to.

no there are only screws on the side shown, also if I did mount itfrom the other side then wouldnt that mean that all the cables are spinning round and round?

Looking now there is more than one version of this motor and I think I should have gotton this one that has the same model number!

You just need to get the GWS outrunner stick mount, shown in the following picture. It's much easier to mount this way on the P-40 than with a firewall mount. To get the correct prop clearance from the cowl, just trim off the front of the stick if necessary. Then get a collet-style prop adaptor that fits your shaft... probably a 3mm or 3.17 (1/8 in.) collet. That will give you a 5mm shaft diameter on the prop end, so you will need to use an APC prop with the different hub inserts to fit different shaft sizes, or drill out a GW DD/HD prop to 5mm. Here's the pic:

Hi est1976

I have one of these 2409/12 (not for the p40) and it can be configured in pusher or tractor mode, by changing the prop shart orientation. So carry on with what you started doing and you should be fine, it will reverse.

i have this motor in another configuration. i remove the alan screws one on the front and back. then i pull by hand the outer case off, its a little tuff because of the magnets. then i take the outercase with shaft to the drill press. i put a hole punch in the drill press that has a smaller dia. and press the shat out with the punch.. i then reinsert the shaft backwards and line up the flats for the set screws and walla.. they fly all the same out the front or back.
