O.S. is on track designing engines to compete with today's demands for POWER. O.S. has their newest line of engines 105HZ and HZR version engines. The R version has a regulator attached to the carburetor system to meter the incoming fuel. O.S. calls it DRS (Demand Regulator System).
The 105HZR produces 3.75HP on the DRS system, this is enough power to fly smack without the loss of head speed compared to the previous O.S.91s. The use of 15% fuel will also save on the wallet in the long run.
The O.S. 105HZ at 17.17cc can fit in the engine mount dimension designed for 61 to 91 size (10 to 15 cc) engines. The 105HZ is the a engine you have been waiting for to install in your nitro 3D helicopters.

I'm seriously considering one of these for my N7 build but I'm torn because I recently flew a buddy's N7 with the OS 91HZ-R 3d and that heli felt amazing. It was so quiet and smooth and had loads of power. On the other hand I haven't had a chance to fly the 105 and I'm sure it has even more power 3.75hp is a TON of power out of such a little motor. Choices choices choices.
