Motor driven tail rotor spin the same as belt driven tail?

Im trying to rebuild all my micros to fly indoor at an indoor funfly and im not sure if the direction of the tail rotor is spinning the right way.

Its a blade CP pro with a brushless Park 400 main, eflite G90 HH, GWS tail motor and carbon blades and rotor.

Do the motor driven tail rotors spin up into the downwash like the other belt driven tails like on minis?

If you are running a direct drive tail (you didn't specifically state), with a normal pitch CCW tail prop, it is not possible to have the prop rotate up into the downwash when you have CW rotating main blades.

oh dang, i forgot to put how i have it setup.

Im using the GWS motor and the stock rotor and gear setup. Its pretty much the same setup as the helimax Axe CP tail. The longer GWS type motor with a pinion on the shaft the same as the little stock motor but alot more power and athority.

Geared rotor setup like you have will spin up into the downwash (top moving toward tail). That's how it's set up stock, and you just swapped the motor, from what I understand.

DD with pitch going the same direction as the stock rotor will, as Martyn said, spin reverse, with the top moving toward the nose.

I did swap the motor but you cant get them with the little gear on it. The motor and gear is 2 seperate parts.

I think you can get the axe CP motor and it has the gear on it but they want 2X more then if you just build it yourself.
