It flat out hauled until the wings folded on it's first high speed roll . I just ordered 2 more P-40's and 2 P-47's to experiment with making one hold up to the power and then playing with lightweight setups in the others .
Park 370? Whoa thats complete and total overkill?
I'm not surprised the wings folded...

Heh, it was all I had here, so I gave it a shot. The plane actually flew better than expected at that weight, just didn't slow down too well- it dropped like a rock at low speeds . I am going to build another one with the same setup, but reinforce the wings with CF and see how it goes. The other ones are going to be more practical setups.

I tried the plane with the stock brushed motor and 800 2S and I just could not get it airborne. However, I did not have a manual when I built that plane (friend gave me the cox kit missing the manual) and I think I had too much throw in it, causing it to overcorrect and stall easily on launch.

Here is a video of my Cox Corsair @ 3.8 oz AUW with a AR6400L receiver.

Just wondering what ESC are you using with the AR6400?

Is your motor 2S?

I'd like to do a setup with an AR6400 however I can't find a light weight ESC that lets you use 1S for the RX and 2S (or more) for the motor.

This Turnigy ESC does the opposite: runs 1S motor but has a switching BEC to supply 5V to the RX. Neat! If only I could find a suitable 1S motor for these COX warbirds. I was thinking that this Turnigy 16-06 motor has a good KV but not sure if it would be enough? Probably something more like 3500-4000KV would swing a 5x3" prop fairly well.

This plane is too heavy for a 1 cell setup. You have to use a 2s lipo. No one has done a 1 cell Cox warbird that I know of. The AR6400-AR6400L has to be converted to 2s operation. Its all here https://www.rcgroups.com/forums/show....php?t=1269743

Ok, that is a long thread and shows a AR-6300 setup as well. Here is the post that shows how to convert the AR6400L to 2 cell operation.... https://www.rcgroups.com/forums/show...6&postcount=51

Maybe clear your cookies and try again? I just checked it out and it is working fine for me as well.

I live well within the US. I still get a blank white screen no matter what computer I try, but I can access it through my iPhone. I'm just not computer literate enough or something.
