Henning,

It will be interesting to see what curves and settings you like once you have a chance to fly and adjust the D3. I found the curves needed to be quite different between normal flying and...

As the amount of side area increases, the distribution of side becomes more critical to avoid yaw wiggle in turbulence. The affects of CG on yaw also become more pronounced.

Henning,

I have completed some flights with the V4 and the D3 ESC and the 18SZ transmitter. Falcon 23x20F and 23x22R, Pyro 600-970, Allure @ 4550g with TP5000s.

The endpoints for the throttle...

Interesting.

The smaller diameter rear prop is to keep the tips of the rear prop out of the tip vortices of the front prop. The folding aspect.....it is a "buffer" per se. Flexing of the prop...

To echo a bit,

Yep, the 23" props definitely increased peak amps static and in air. However, for flights of equal size/distance/pace, the 23" props are more efficient. If Throttle Tech were used...

Henning,

Specific to flight performance -
I have run the Brenner CF 20" props back to back with the APC 20" props. With a small shift in the motor batteries to keep the CG the same, I don't...

Hi Pippy,

I switched to the V4 drive before trying the 23" Falcon props, but, based on the data I have collected from both the V3 and V4, I think they would be suited equally to either drive. ...

APC Props?

Hi All,

After speaking with APC at the 2016 US NATs, this past fall, I sent a bunch of prop data to APC. APC did some modeling/design calculations for a new set of props - target was to match...

I don't think any of the sensorless ESCs can record RPM when the brake is engaged. Most radio brands (and Eagletree) make a variety of RPM sensors...it would need to be of the optical or magnetic...

Hi Vince,

I generally use the stock setting of 20 for the compensation factor. On the higher power setups, I might increase it a little bit to 22 to 24. Depends a lot on batteries used, flight...

Bill,

I would definitely look at improving your cooling to your motor. From the ESC side, PWM can affect motor temp. If the ESC is running cold, you might be able to increase PWM and get a small...

Processes inside the ESC and motor are happening at hundreds and thousands of times per second. Peak amps on a watt meter, or ESC log can be misleading as they are not logging / displaying at such a...

Hi Robert,
Catching up on this thread and just saw your post.

My Allure at the 2015 NAT was setup with a V3 with Neu 1512-2Y (1380 KV), 10.15 gear, 22x20F and 21.5x20R, and of course Throttle...

Correct. The current 4.22 Castle software will have problems with the high commutation rate needed for a 14 pole Pyro 600 with the V4 Contra. Max achievable prop RPM will probably be about 3900...

With the relatively warm winter, and generous loan of a few motors from Brenner, I have been able to accumulate quite a bit of flight time on a V4 system with several motors.

I have used alum bolts on several planes for weight savings. Haven't sheared or deformed any yet, and most of my flying is from grass fields that most people would call "rough".

Brenner,

For sure the Contra is a positive.

I'm not sure the Contra helps the KE Top Hat anymore than any other maneuver, per se. For me, when the Contra is in a well matched and trimmed...

I think we are in violent agreement. As this thread is about the Allure, I kept my comment on the noise issue brief - my intent was to point out where I believed the basis was for the zero...
