I have stacked in Ashura the counter-rotating propeller engine ASA210CPI. By the way, the engine body (mount included) is the total weight gain of about 70g +20 g of about +100 g, spinner is compared to the normal propeller for. In addition, it is the weight gain of about +130 g When it is compared with the YS170.
I was going fly if the wind is good, but it was the only engine adjustments in high winds the 1st unfortunately.
Two counter-rotating propellers for F3A you are experimenting over 10 years, this thing will be the third generation. Because there is the word "third time lucky", I just want you to practical use soon
Further down, it looks like the various incarnations start life as DLE head/cylinder grafted onto a machined crankcase, with regulated Heli carb??
