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

Hi Brian,
Saw the model on two WorldCup events and could peek into it and ask Peter some questions. For 'real' info please ask Peter.
Hi Brenner,
Yes it flew very well.

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

A lot of innovations are built into this model.
As this is the contra-drive thread, the motor is a Pletty Advance with own build drive. Props are direct driven.

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

Hi Malcom, have two new types from autumn last year. They feel the same. Cogging is mild like what is felt with a Plettenberg.

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

Hi Vince,
Have flown the Gaudius now for two years. This first thing two years agoI thought that this uphrust could not be right so I eliminated it. Could not fly straight up any more.

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

Hi Brenner,
Thanks for the suggestion.
I do not exactly know how it should look like, but think it looks OK.

No paint, it's Oracover. Photo's do smoothen things up.

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

40mm wide on my Gaudius rudder. Makes the plane very stable, no complaints.
However the drag it generates makes me hit the throttle too much to reached my preferred pace.
Have to experiment with...

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

Hi Brian,
Thanks, so have to ask Brenner for a Hacker to Neu conversion.
Just bought the Schulze l-32.115 to tackle the power problem so that one that must do the job.
The YGE must then be very...

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

Don't think that it got that hot. Measured about 70 degrees. Thats still fine but the outside temp is 10 degrees. It wont be fine in the summer.

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

Anyone with Amps usage on the 13XL?
This week started to use the CD again after the winterbreak. Used it only for a few flights last autumn.

C5013XL, - 22*18 front 22*20 rear, Schulze 32.80KA,...

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

The WindSPRO has a relative tall vertical fin and it is reported to respond well to the contra. Perhaps this is something that works. Just received the Arixtra kit, it has an exceptional tall fin...

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

Hi Brenner,
Just a bit of speculation...
Already with single prop setups I have the feeling that when the intersection of the vertical fin looks more like a 'real' profile (e.g Winds PRO) the...

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

Hi Brenner,
Thanks for all the input. I was triggered by the remark of Dave about exiting a maneuver where I exeprienced it the most too. That made me think of being power on-off related. Time to...

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

Maidened the CD today. Now I know what many of you have encountered and are trying to eliminate.
Obviously the Gaudius is susceptible to this phenomena too.

My other Gaudius I fly with the...
