If it is the newer style collet that extends back to the front bearing of the motor, it is not intended to be removed as you described. I believe the motor should be removed from the plane and...

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...

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.

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...

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...

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...

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...

Isaac,

From my experience with the Contra, I would not change downthrust.

Side thrust should be zero. ....or very close to it. While the torque is balanced, that does not necessarily mean the...

Thanks! Re-reading my post, I agree with you that I should have stressed a bit more that my setup is very capable of abusing the lipos if not used judiciously. A couple relatively simple...

1. I use throttle as needed based on my perception of the airplane speed; not the attitude of the plane. Ie, I don't go to full throttle in every climb simply because the airplane is in a...

Matching the apparent :) speed with any of the prop sets is not a problem. For my plane, I am finding it can be flown at a very slow constant speed even with the higher pitched props,...

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes
