Hi Atull
Steph uses 5 % and 7 % oil with 20 % nitro (propeller is APC 19x11).
He did'nt test lower nitro. But there is no problem of reliability with 15 % nitro, only engine will be less powerfull.
I saw his flights. With normal 170 duration is about 9 mn and with YS170 cdi duration is about 17 mn.
After flights no need to clean the plane.
Regards
Thanks Papaone. The 17 min flight duration is very encouraging. Clearly, this is going to be one great, and popular, engine.
It should ship towards the end of this year in Japan. Yamada is known to normally slip its estimated shipping dates by a month
or two..
