Rans S-9 Chaos (54″) – Plan

Full Description

The model is about 1/5th scale, which gives a wingspan of 54”. Peters favourite combination of a 3541 1070 brushless motor, a 40-amp ESC and a 3S 3000mAh LiPo would be the right power set up.

So here we have a model that looks great and is pretty easy to build. It weighs 3 lbs 13 ounces ready to fly. This is one of the nicest, best-behaved models that Peter has flown in a very long time – and he’s had quite a few favourites!
