I think your GWS-40 will feel a tad underpowered with that motor. I personally was only satisfied with the power I got from the motor below paired with a 30A Turnigy ESC and a GWS HD1080 prop ;

Another spinner idea: could you use cowl snaps placed on the bottom of the spinner and on a base plate so that the cowl could be snapped on and off the base plate?

The last one is a combination of both above. More powerful than the first mentioned above and more efficient, but a little heavier. The 35-36C is a good powerful motor but maybe to heavy for this application. Plan on building a motor mount on the firewall, at least that what I did for mine. I use a 10x8 E prop from MAS

Roger Lombard reports good results using the Hextronic DT750 with the GWS 10 x 6 x 3 blade propeller. His report is No 9 in the customer ratings.

I have received my Hextronic DT750 but have not had a chance to test it yet because I did not have a spare 20 Amp ESC.

Edit:- I borrowed a 25 Amp ESC and got some preliminary figures.

Hextronic DT750 with a GWS 10 x 6x 3 blade propeller and 2200n Mah 20 C three cell battery.

!!.34 Volts
12.7 Amps
!44.06 Watts
970 Grams thrust (34.6 oz)
7,220 RPM
41.0 MPH pitch speed

I build light... this one has this HC outrunner in it. GWS 10x6 prop and 1300 mAH 20C 3S lipo. A 9 in. prop could get a little more speed, but I prefer more thrust for the nice vertical climbs (not unlimited, more scale-like). Here's a link to some recent video This video was mostly to catch some low passes with some rolls and a hammerhead thrown in.

Thanks everyone. Looks like a lot of good motor options. Nice video Tom. It really showed the area it needs to fly.

Is the epo version better somehow? It looks more difficult for paint to adhere? I'm leaning towards no landing gear due to the noseover tendency. Does the bottom get beat up quickly?

Yes, the bottom will take a little beating. I reinforced the lower fuselage with a couple layers of 3/4 ounce fiberglass.

For me EPO is NOT better. For one thing, it's about 10% heavier, which doesn't sound like much. But that's about 2 oz. more weight with a plane this size, and that can mean the difference between a nice vertical climb and not much climb at all, unless you add a bigger motor (more weight) which consumes more power and usually needs a larger battery to get the same flight times (even more weight). This plane already has a high wing loading... keep it light for easier landings and nimble performance.

If you land on a nice grass field like in my vid, a strip of packing tape down the belly will protect the EPS foam. Mine has sustained no damage from bellying landings.

You've read about the paint issues. There's also glue issues. It CAN use regular CA glue if you consider that a plus. I don't use much CA glue at all on my GWS foamies, so that's no concern. But other glues I DO use don't adhere as well to EPO foam.

Bottom line is if you crash a lot or fly in high winds, the EPO foam is probably your friend. If you don't, build light and it will fly right.

For flying in the early morning when there is little or no wind the EPS is superior. But here in Darwin, in the middle of the day, we have winds up to 20 KPH and under these conditions the heavier EPO model is superior. As well the EPO Model survives crashes a lot better.

Here are a couple of shots of my P-40. It has drawn a lot of attention at the airfield and has prompted a bunch of the guys to get these or the FW-190 to have a little combat and racing. Mine's done as a 325thFS Checkered Tail nicknamed Trixie. Unfortunately I cant find any picture of the Trixie pinup nose art to add to the front...still searching. It runs on the GWS 2215-12 with 3S and 4S 1320 batteries. I really like the power on 4S but the motor gets pretty hot with the 10x6 three blade. I will be going to the Turnagy 35-30C-1100 once it arrives which should be quite nice. Last item to get is the pilot of which I'm still looking for. Trying to find something nice and scale. Other than that I'm having a great time doing scale looking maneuvers and making mock straffing runs on the other planes in the air. Let the games begin!
