hello all

here are some pics of a fellow flyer's (frederick of singapore hobby) new plane, the Seduction WCR made by OKmodel. it's basically a balsa constructed plane which is designed around the seduction line of airframes (wildstyle, freestyle, streamline, etc). the plane is powered by Tahmazo's prototype Contra Rotation motor running a 6S lipo pack per motor. propellers are a custom 15x10 for the front and 15x10.2 for the back.

weight is about 4.75kg including battery packs.

two more pics...

Had a 25 size low wing Seduction with a OS32 in it a few years back. The best plane I ever owned and I had the best day of flying ever with it.

By the way, what does WCR mean?

W for World Championship series, CR for Contra Rotation, hence the name "WCR"

hello

do you have information about the price and the avaibility of the model

regards

I am surprised at the apparent lack of interest in the counter rotating out runner motors for F3A.

Though I have very little to do with F3A, I fly quite a bit of full size acro. The forces emanating from a propeller are tremendous, even at the comparatively poor power to weight ratio of full size acro machines. Without the ability to feel the forces by the "seat of the pants" flying R/C acro, I often wonder how we manage to trim F3A planes so well.

Very neat.
Good to see Counter Rotation is taking off.[X(]
It's gotta be THE way to go.
i'm sure it's these types of break through that'll revolutionize the pattern planes in future, allowing us to escape from the traditional design, tweeked over decades, to perform with a standard, traditional propellers and their effect on the airframe.
Thats already a thing of the past.

As a side note it's interesting to to where the future's going.
It used to be big $ F3A that drove both model technology and flying forward. Now, its ironically youngsters and cheapo indoor foamies thats showing the way.
Counter rotation, reverse thrust and thrust vectoring are allowing a whole new dimension to how we fly, what manouvers we fly and the airframes that'll perform them.

i've seen fred fly it, its downlines are incredibly slow!

here are 2 pics of the red scheme :P

I think people are quite interested, I think its more a case of dealing with the additional weight and complexity of the system and is the trade off really worth it in the long run.

I am looking forward to hopefully seeing a counter rotation prop drive at the WC's in a couple of weeks, at which time I will better be able to evaluate if there is truly a "significant" advantage to going in that direction.

Clockwise, or counterclockwise?

the singapore team will be at argentina this year, a fine time to see the plane in action.

do note that despite the additional motor and the need to use a 12s pack (2 6s packs), the plane still comes in at a very impressive weight of ~4.7kg!

Isn't a 12S lipo pack over the FAI limit for voltage?
