I recently found an online store with one whole double tail set in stock. It was not cheap!

This was all the brainchild of Don Chapman. It was a mean to use longer blades and/or reduce the head RPM without loosing tail control. I flew/practice a lot with Danny Chapman back then.

Later MA came out with a tail speed-up which preety much worked as effective without the complication of TWO tail rotors. They were cool looking though.

They work/hold really well. As far as sound I can hear no difference but then again I dont push the tail hard. Just basic aerobatics with this machine.

Dual rotor setup

I heard that they make the tail feel real solid I have a Dual rotor setup for my JR Ergo 50 Heli but never tried it at least not yet

The pictures are not what I expected. I had envisioned them as 90deg apart.

I suppose the largest down side would be one of the rotors runs in the wake of the other making it less efficient - that along with the added parts, cost and complexity already mentioned.

Really cool though.

The big thing about this setup is that they where tunned in such way that during hovering with no crosswind one side is holding the torq the the other is set to 0 degress. That way, it is something like having a huge vertical fin. But when turning the heli sideways to the wind and applying tail rotor input to hold that it was like reducing that side area effect. You have theoretically a bigger stability withou losing control power....

As I said that was the theory that time, but I never tried. It was used maily by the F3C guys... No real 3D back there...

If I remember correct Don chapman was behind this in helping MA the goal was to take some of the tail wondering tendencies out during some of the FAI manuvers. I had one on one of the first gen XCell pro's. Worked well. This was also back when the best gyro available was a Piezo, which still required tail rotor mix in the radio.

The idea was less surface area presented to the wind and more authority.
