Menno,

About 10 years ago a friend took 2 AXI motors, one with a hollow shaft and made a really nice motor with the props contra rotating. We put it on a model simular the Convair XFY Pogo and were able to take off and land without any problems on the tail. The lack of torque made it pretty easy to do and didn't have to have huge surface deflections to get the job done. Spektrum has a new set of receivers with stabilization that I want to go back and try and fly it again but I unfortunately gave the motor away.

The large pancake motors that are made to have a slipring in the middle should be good candidates but would have to be rewound.

Max,

I didn't want to have to add another four motor drivers so I just put them in parallel. Not very efficient but it flew fine. It weighs close to 70 grams with battery so when all four props were off it was struggling but controllable. I pulled off each prop one at a time and it just got a little weaker each time. No control problems at all and it was just our normal Quatos.

I found a cheap Quad at the local drug store, 40Euro (with radio, Video cam with 4Gb micro mem card).
I put the M4 inn, with 600mah LiPo and Blue Tooth module.
total weight 95 Gram.

Very nice find, flying good - a bit noisy, though.
What´s the flight time with 600mAh @ 95gr?

At a drug store? They obviously know how to please addicts with drugs of all kinds.

I know, not common to find it there.

It flies 6min with this setup.

Here is my newest M4 build. It is a FPV H-Quad.

Nice one, Dirk!
Flies smooth and agile.

btw: how´s the VA1100 coming along - do you get a proper image on your goggles?

I was quite surprised that I could get a GPS lock in my house so I had to see if it would be able to hover in Alt/Position Hold.



The quad has a M4 v1 board, 8.5 Hubsan motors and props and a custom 3D printed frame.
