I thought that as I have a flamewheel sitting here doing nothing I would use it to test the latest release. Not bad. I would say that the camera outputs were better than the Naza.

It seems like you had some other problem with the ESC's as the motors were pulsing the whole time which would suggest maybe wrong timing.

Thats ripper mate!

I use Electriflite.co.uk Zippy's are ok.

Charlie All I can say is good luck with it. If you can get 30% then I should contact all of the major aircraft manufacturers. you will become very rich. Here is a large quad with four bellmouths, these are actually refined ones that give better performance in a crosswind yet I took then...

Bart If you are seeing frequency dependent oscillations, it is probably due to insufficient rigidity in the motor arms. Although prop. balancing is essential, aerodynamic disturbance (usually seen in the descent) can twist the motor slightly and cause an eccentric movement which magnifies the...

Bart I cant explain what Charlie is doing with his own test evaluations. What I can say is that I have a test rig that gives very accurate results. As the bell mouth is an obvious experiment for anyone with a little knowledge of aerodynamics it was done to death here. In fact if you look at the...

The only way that you can get more thrust is by using the bernoulli effect to create low pressure around the rim AND have full pressure recovery on the back side of it. The velocity is simply not high enough to make a significant difference. The other way is to move a greater weight of air...

Ah! another case of someone trying to change the laws of physics. If you believe that you will believe anything. I have played with bell mouth designs for a very long time. It was the fundamental element in the design of air intake systems on formula 3 race engines where all of the air that the...

Yes T-Motor 4008's HiModel ESC med. timing.

Paramount to stabilisation at this level is the torsional rigidity of the arms and the weight of the props. You cant do this with motors on a long stick whatever you do electronically. Balance is not just about static balancing of your props. when the model gets into a descent with turbulence...

Herewith a couple more shots of what a finished one looks like.:tennis:

A better solution would be 4 high performance racing RC car engines that run at about 40,000 rpm and give a lot of power with very good throttle response. You gear them at about 8-1 and then use a variable pitch rotor hub. idle-up throttle and normal fc control on the pitch. Any difference in...

That did not happen in the sky. that damage came from hard contact with cumula granite. I have only seen a breakage like that after a fall from about thirty feet.:upset:

I have been using the 787's for some time now. Not as smooth as the hitec HS-M7990TH but a lot faster and half the price. Hence I don't use high reduction gearing.

I see a few people are using these motors. I wonder if these are yet another rebadge. http://www.brushlessmotors.co.za/index.php

I am using the DX-8 with the telemetry link to monitor the battery. Bought it while my MZ14 was being repaired and now I wont go back.

Interesting how much the motor arms flex! Even more on the Flexacopter.

Nice. Simple but effective approach to getting the best out of it. Freedom to go where you want.
