I have a 700 mAh Etec 2cell that weighs 1.4 oz (40g) and am about ready to purchase one or two additional batteries.

Not having had a model that has a small area for adjusting the battery placement, my concern is getting the appropriate COG without adding lead.

So, any suggestions for a good battery for the moth to set the COG correctly, or am I being too concerned and any reasonable battery that fits will get the COG close enough?

The moth was the first plane that I looked into here on rcgroups way back in 2002. It's nice to (nearly) finally have on flying!

Thanks,
I wish I had known, back in 2002, when Judy & I built our Picos, (her's pictured), that almost 5 years on, we would still be enjoying them. Absolutely the best R/C model I ever had!
(That's the 2S Lipo, in the front seat).

Beauty is only skin deep!! OK, with one or two notable exceptions, one being Little Fishy which is a work of art through and through. The Moth is as beautiful the next morning as it was the night before!!

Agreed, and very eloquently stated. Thanks for sharing....

Oh man, didn't mean to ruffle feathers! I need a new slope glider but none are to be had so GWS is forcing me to go to e-flite! My current moth had the bottom of the fuselage tore up by a prop strike from underneath, now it whistles as it fly's by!
Since I feel I need redemption, here is mine flying at e-fest last winter at the mecca of RC-- Champaign, Ill.

Is that decision cast in stone?

If you ever DO find out what is causing the altitude limitation, I hope you will keep it a secret! The mystique of your 25 ft. Moth is now stuff of legend, not to be questioned.

Well, that's much better. Now, go fly and sin no more....

Great photo, by the way.

After it gets to it's ceiling, I can back off the throttle and that's where it flies best.

Doug.... no, it's cast in cement! Haven't you ever seen a concrete block?

If I can figure out what the problem is.... you can bet I'll post it here...

In the meantime..... here's a couple of pics of it in all of it's glory.

Still looks pretty dang good for a five year old plane!

Well, of course! That, density altitude, methane/hydrogen blast-pockets, being on the western edge of the BM triangle, and that cowl flappin' in the prop, would keep even a GWS Pico Tiger Moth, (which, I hear, are now history), down!

The cowl doesn't flap in the prop. Sometimes it blows off.... but it doesn't interfere. See those two bamboo skewers that hold it on? If I really want to keep it on all I do is hook a rubber band to one skewer and pull it under the nose to the skewer on the other side. The cowling is fastened rigidly that way.

Yeah, Doug.... I'm looking at that down thrust too. When I first got the moth, I broke the stick.... and it moved before the epoxy dried. I believe that's a major problem right there. I'm going back to "A" gearing and a 9070 prop. And, I'm going to move the motor stick up. It's still odd though... it flies so well to it's ceiling, it doesn't appear to be affecting it until it gets higher up. It ligerally jumps off the runway. I also found another problem with a control rod. Between the two of them, that may be the answer.

When I find the time to move that angle up and repair where a control rod is sticking... we may see a new and spirited moth. THEN, if I decide to go BL, it won't be any big deal. 8-)

For comparison purposes, I took these shots of my Moth, showing down angle and right thrust angle. Not the best pics as I didn't have anyway to show show a ruler or some other straight edge as a reference line. You might want to look at the inner cabane mounting line to get some idea of the down thrust that is set up with my Moth. As noted so many times before, in jest and as a matter of record, the plane has no problem obtaining good altitudes. One thing I don't do is loops and other semi-aerobatics. The IPS has just so much power, and the plane is weighing in at the upper limit, 9.1 Oz, AUW, less altimeter. Hope these images may be of some interest and help.

Can you tell me a bit more about your Feigao motor? What type, gear box, how it's mounted, etc. Thanks.

Hey folks,

I'm looking for advice from those of you who've built a TM 400 and added ailerons to the upper wing. Specifically, how'd you connect the ailerons together? A pic would be fantastic (hint, hint)

Thanks, Dave
