Jorge, I will really be surprised if you get a response from TTE or anyone from TT.  If they haven't responded by now they are not going to.  The only way you will be able to get anything is to call them as they are trying to ignore you.

I am going to put a 12X8 prop on it and see how that runs on a Hangar 9 40 size Super Stick.  I pick one up used from one of my club members for $50 US.  I am thinking of mounting the motor sideways.
