View Full Version : GWS Tiger Moth 400
08-18-2005, 05:42 AM
New to the site.
I just finished building the GWS Tiger Moth 400. The instructions leave alot to be desired, but the plane went together pretty smoothly. One thing I'm having a problem understanding is the center of gravity. The manual says between 0-10mm from the leading edge of the lower wing. It does not say exactly where on the wing to make the measurement. (The wings are swept back.)
Do I balance the aircraft at the center of the lower wing?
Any input / advice would be greatly appreciated!

From the leading edge where it crosses the fuselage.

Thank you for the replies! I hope to take her on her maiden flight tonight if the weather is good.

Good luck with the maiden RW.:) Let us know how it goes.

Several of us fly the Big Moth. Be aware that the landing gear is the weak point. We have cut 1/16 ply and added it to the area around the landin gear struts and covered the black plastic part. Like anything you fix, another place lets go. It does fly well, keep the power on and the nose up on landing.
Good Luck and have fun.
Some leave the gear off.

Too Funny, George! The maiden flight was beautiful. She handled great, even did a few rolls. Very responsive! I lined her up for the landing and brought her in fairly slow. The landing gear hit the grass and off they came. No damage though. I reattached them at the field and took her up again. This time, the gear stayed on during landing. Thanks for the tip. I'm going to reinforce the gear before going up again. The Big Moth rocks!

Thanks for the update RW! Glad to hear the maiden went well and that you seem to like the Moth.:D

Gotta love how graceful a biplane looks in the air.

Well, as of last night she has had 4 successful flights. This is a great plane. Very graceful. I also had a few good flights with the GWS Corsair. Gotta love foamies!

What did your CG end up being?

Right about 8mm from the leading edge where it meets the fuselage.

I have been thinking of buying the 400 version. If it flies as great as the Pico TM I'll be very very pleased with it.

You will love it! Blows the Pico Moth away. I fly mine every chance I get. I'm thinking about going brushless with a 3s LiPoly . Ought to rock!

yea what RW650 said ,
It's gotta be somewhere in this cornfield.....
or .........It's gotta be somewhere in this beanfield.....
I certainly have searched for downed planes in both crops,,,only once or twice of course :rolleyes:

I think we all have done that a time or 2!

I've had a blast with my 400, Started with the stock dia wheels and had trouble landing on grass, then went to 2.75 dia wheels. My TM would nose over every time. Off went the landing gear, problem solved.
