And tell me what you feel?

Mr. Lin
but is the 400 motor a 6 or 7.2v?

GWS is not call the motor in that way.

So I am not sure what a EPS400C motor should be called? But if this is from a GWS EPS400C D gear drive power package, just do what I said. match with EP9050HD, 3 cells GWS 1300mAh Li-Po.

Try this way! We flew under this combination, and sound like BL performance! Make your GWS WW-IIs alive from a gentle sheep turn into a wild cat!

I maidened my corsair last night with the EPS-400C D gear, EP9050HD prop, and 3 cell GWS 1300 Lipo.

WOW was that thing faster than I thought it would be. I did about 2 5 minute flights on the battery at about 3/4 throttle and the battery never even got warm at all. It looked so nice in the air and flew very well even though it was a bit tail heavy. I thought the CofG was at 55mm but with my fat fingers it might have been closer to 60mm. I'm going to move it forward either way.

Great Times.

I posted a video of the maiden in my gallery. The video is not so good due to it being from my digital camera but you can get an idea on the speed. Thing climbs great and is very responsive. I love it.

Thanks for the tips Mr. Lin and what a fun plane to fly and build!

eran k,

i have an e-starter with a simlar setup to the 400 warbirds and i am currently changing from the stock motor (i think its a 7.2) to a zagi 400 which i know to be a 6v motor

i'll post my findings as soon as i can

I'm also considering trying a tuned zagi 400 which has been timed for reverce rotation later

You got it! Glad to hear enjoy the same result like I had!

Wish there will be more Ezoners get this tip apply to there GWS WW-II and Formosa.

I have been flying GWS 400 motors in my Spitfire and Spitzeo for a year now it helps in C/G
Thank you Mr. Lin
I have not seen the P 40 on sale yet.

A slow flier prop? On a warbird?

Yes, that is all I have. Bags of GWS slow fly


Not running with the big dogs yet

Wish to see more reports about set up GWS WW-IIs to be with EPS400C D gear drive!

Pls share your happy experience here!

Well, I got me a 400 D and thought about where to put it bearing in mind it's 50% heavier than the 350. Seemed a pity to weigh down the Zero or the Corsair. Now which warbird needs weight up front?

Right - my ex-350B and now 400D Spitfire is at scramble readiness - tomorrow may see the maiden. I don't have a 9050HD so its got an APC 9075 thin electric.

The ZERO absolutely needs more weight in the nose.

As I mention in the beginning how to match the system and props, You may try EP9050HD for 3 cells, or other similar size prop near 9050.

9075 is a little too much heavy in this application.

Overload will make you feel the performance like soft, yet battery energy lost quicker. Unless, the above set up is too hot for you, you may try 2 cells with EP1060HD.

Sorry Red61 - my Zero has the lightest front end loading of any of my warbirds but it DOES have a little more downthrust than standard and it has the wings reset to the correct AOI.

I'm assuming you've reset your wings?

And thanks Mr Lin, I'll bear your advice in mind

How did you reset your angle of attack??? I'm going to leave mine std to take advantage of the "automatic lift" that red 61 has mentioned, but am curious how you adjusted yours; shims??? recarve fuse??? or..... ?.

thx,
