The RCS night weigh what the os 1.60 wieghs, but add ignition, ign battery, and ign switch and you are 40 + oz with battery.....oh and less power. I found one guy that had pretty good luck with this combo, he is running it with no muffler tho! more rpm, but DB's are in the 110 range.......LOUD!


Using a Satio 150 on mine, getting prop numbers real close to the 1.80 hear at sea level, but much better on fuel with the smaller carb.


I agree that this plane should have a four stroke on it! I love os engines, but you can not beat the sound of a four stroke.
