Subscribed. Looks like the covering and cowl match up pretty good in color.

As was discussed in the previous thread, can you tell what the purpose of the oversized cowl flap area? Is it that way for cooling?

What power setup are you going with?

the oversize cowl area dose not appear to be used for anything. when it was molded it was done in the open cowl position. i wish it was done in the closed position. in the electric set up on the manual the esc is located on top of the electric motor box instead of the bottom for cooling.

as far as my setup goes i haven't decided yet. i was hoping to hear what others have done for 50 size planes.

So are you installing the power 52 or the power 60? Also, are you going to run 5S or 6S?

I've run the numbers through ecalc on the 52 for a couple 3 blades. Also flight tested the 52 with the 14x9x3 on 4s in my 190. It flew it ok, probably about the same as the P-46 turning a 13x8x3 on 4s, maybe a hair faster. The 190 has way more drag with the open cowl than the P-40 will have though so it may actually be a good scale setup.
I just ran the numbers again for a 5s on the 52 turning a 13x8x3 and they look pretty good. It's saying 69 amps( my test numbers have been coming up 3-4 amps less than the calc) a little over 7 minutes run time on a 5s 5000ma, should give just under 10lb thrust and a pitch speed of 66-68 mph. Looks like I need to buy some 5s packs as well as some of the Graupner 3 blades to do some more testing.

I think the great setup would be the power 60 on 5s with a 3 blade prop. The same setup whats on my friends Kyosho P-40 and flies it great.

Do you know what 3 blade he is running? I just ordered a couple of the 15.75x13x3 APC's and a 16x10x3 MAS. I think I'll spend the money I was going to use on the Graupners for a couple 5s packs instead.

I built the 50-size Hanger 9 Corsair, and use the recommended .46 brushless motor on 4 cells, and it provides excellent scale flight; I have no desire to fly a scale plane at rocket speeds.

Staying away from a bigger and heavier power system keeps the weight down and the landings easy.

I would think their recommended Power 52 brushless motor would be more than adequate.
