Somebody else thought of it first and started, but got stalled some months ago. I think their design was lacking practicality.
Have you looked at the Armattans?
I've been flying one for awhile (lost it so a new one is on the way). I'm looking at building one with the multiwii pro with GPS (return to home for safety) as a stable flier for cruising around doing some video and wearing pretty lights for the night sky.

With no way to adjust that, not sure where to go from here.

I'm going to feel really dumb if I have to start putting weight back on...

I hope the DD mod fixes it, still waiting on the parts.

Is your tail actually wagging a significant amount? Mine just sort of twitches no more than about 1/4" if even that much. I thought maybe it was due to flying in the cold as jkoosh27 suggested, but I just tried it indoors and it did the same thing. It doesn't do it steadily either, just intermittently.

Not sure how a 9116 would handle the extra weight.

It might work mounted on my 9116, since it weighs 191 grams

250 huh?, Vader have some stuff for that size? I'm petty sure my saber can handle it.

Mine was like yours is now before I trimmed the blades again and removed
another 8 grams.

Now it wags by over an inch.

I just tried taping two nickels (10 grams) to the 9116 and flew it
around. Still had wag.

Then, without shutting off the radio or heli, I pulled them off to see
if there was a difference, and the wag went away ?!?

I'm stumped.

it really sounds like the gyro acting up mine did that off and on for awhile till the pcb burnt up the new pcb i don't have that issue i can hover for about 6 sec without input of the sticks and the tail follows in a straight line when flying

My tail motor is dying, it's on 40+ flights, and started acting
up after 20.


Probably the problem.

At least I hope.. The parts to replace the tail are already paid for.

It also could be the way I mounted the battery. I skimped on servo tape,
and was just using velcro straps. One of the nickels was under a
strap, so when I pulled it off, it probably changed the way the battery
was mounted. It's really the only logical explanation for the change in
fight behavior. Nothing else was changed.

[ UPDATE ] It's not the battery or how it's mounted. Tried all kinds of
positions and mounting "tightness".

I suppose a bad gyro is possible. I flew into a fence the other day at WOT.
But I had slight wag before that.

Looks like my direct drive tail conversion is the next step, if I ever get it.
I ordered it a while ago.

then it has to be either the gyro or tail motor failing

The Phantom has all of that RTF.
Makes sense! I'd love to know how it goes!
