Tigermoth 400 questions?

Hey Guys,
I have been planning on building a GWS TM 400 for a while now, and I really want to do this right. What I am looking for are the best components so that I can start getting everything together. What I need are the following:

1. I seem to be having difficulty finding a source for the kit in the WHITE unpainted version.

2. Choice of brushless motor / ESC. Recomendations ? ( I was very happy with a Mega 16/15/4 in a 48" Unicorn) or should I stay with the S 400? I'm not trying to tear the wings off the plane, I just want it to fly well, and be aerobatic.

3. Choice of battery packs? I am looking for flight duration, and adequate power. I am also looking to get into Lipos, but maybe not until spring, depending on whether it just makes sense to go the Lipo route from the get-go.

4. Alternative prop choices other than the 10 x 6

5. Looking for info on building mods, so that I don't have to retrofit later, I.E. strengthening weak points, improvements, etc. There is a lot on the smaller version but not too much on the larger plane. I also have not seen anything as to landing gear reinforcement issues. I know this was a weak point with the smaller version.

This is my winter project, and the plan is to build it slow, and have the best possible result. Your help is much appreciated.

I glassed my tm400 and most recently installed my mega 16 15 3 with a top creations gearbox ,only 1/2 oz heavierthan eflight 400. Your 4 turn and 2.5 gearbox with 12x6 propwould be a great combo . I also cut ailerons in the top wing for a better roll rate,you can always do that later .

I appreciate the tip on the motor/prop. The Mega that I have is staying in the Unicorn. Should I consider getting another, or is there a better choice?

I like the 3 turn the best for flexability . Upto 320 watts on my formosa only 240 watts for my moth . I fly sp300 sp400 & sp600 planes with these motors 350 whatts is possible with 4s packs . Also this motor is only 1/2oz more than my eflight pork400 brushless.

Should I consider the Phoenix 35 ESC or swap out the Phoenix 25 from the Corn? I could then use the 35 in the wing.

I'd swap the -25 or get a new -25, as you prob won't be needing more than that!

Hi,
I will get the TM 400 in whatever setup you want. I have the Yellow ones in stock with the 400 motor. They fly very well stock. I can also get the white unpainted version for you too. I will be placing a follow up order with GWS soon and and would be more than happy to add anything I dont have in stock to the order!
Peace and Happy Holidays
Vammy

Appreciate the feedback. I will be placing an order soon, but I have to hold off for now, as I don't want to rain on my wife's parade with whatever holiday shopping she is currently doing. She knows that I have been planning this since late summer.

Thanks,

Bill

I just finished the TM 400... Everything per kit... motor, prop, battery..8x800 Nimh.
All up weight 22 oz.
Flies well, much better than I expected.
It does need (apparently) a lot of aileron differential.. the nose pulls to the outside in an aileron turn..
And drops to the inside with a rudder turn..
Looks good in the air...

I expect the gear may be a problem, but so far it's been good. I changed the ailerons to differential last night.. maybe fly today, weather depending.
It does handle a mild wind nicely.

I know when I was flying my nitro bipes that I had to use rudder and alierons to get smooth turns. FYI

The differential I put in last night improves tracking in rolls, the nose doesn't go out as far.
But the roll rate has noticeably decreased.
I cut up a servo wheel, as there isn't a wheel supplied for the Cirrus 09 I'm using, and screwed that to the existing straight arms as shown..
There's about a 50% differential now.
On the full-scale TM, it's rigged to almost no down aileron at all..
