IceWind:
I'd say you're already progressing.
Nice flying you already mastered it. :)

Sorry then, I didn't knew you plan was to do FPV with a plane.

I use goggles, I've been working to hack the MultiWii code to feed sensor data into my OSD to show a Virtual Horizon. That will help to identify the tricopter flying attitude.

Btw, for the owners of the PhoenixRC simulator and that want to try to fly a quadrocopter that is already possible. The last update adds the Gaui 330x.

Happy Days:
I read an interesting article the other day, (well, I found it interesting anyway) about tri & quad copters. The author recond it was better to have small diameter props rotating quickly, than large props rotating slowly.

His argument was that although small props aren’t as aerodynamically efficient as slow rotating larger props, (and therefore ’waste’ battery power) they have less kinetic energy. Therefore they can slow down or speed up more quickly and offer more immediate response to the pilots input.

Don’t know if that little gem of info is of any interest to you ’copter guys :?: . I thought I’d just throw it into the arena :roll:

Hi Keith , I used 1100 KV motors with 8x4DD props, the norm in tricoptor would be 750KV-950KV motors with 10" props.
I was working on the theory that this would make my coptor smooth for slower style of flying.
I think it works    :?:
Now for an interesting observation,
I have 7 x 2100 3 cell packs.
The older packs are well used and I get about 3mins flying and then the coptor looses its steadiness, it goes completely out of trim.
When I use a new pack the coptor is rock solid for 6min .
I now need to buy several new packs. broke again
 :wink:

Happy Days:
It seems you’ve come the same conclusion the author of the article I read did: For better control, small fast props are better than slow large ones.

Re Your older Lipo’s. I’m wondering if, being older and less able to hold their voltage under load, whether  they might be adversely effecting your gyro :?: . (Assuming that you're using a gyro that it.)

These copters are not something I’d be interested in flying myself, but they do seem to offer good camera platforms.
I enjoy reading how you venture is coming along :) .
(In fact I was so impressed with your first attempt I spent yesterday morning re-cutting it to see if I could make any improvements.)(Not sure I did a very good job :oops: )

Good luck with buying 7 new 3S lipos………they aint gonna be cheap! :evil:
