As you may know I have two Bob Cats. One is stock and being built without retracts. The other one has been sheeted and painted and flown once with a turbine.

Today was balance day.

The stock Bob Cat without retracts needs 4 oz. of nose weight. It has a .45 engine.

The sheeted/painted Bob Cat weights 2 pounds more and is very tail heavy even without engine. It needs 11 oz. to balance w/o engine and 15 oz to balance with a .45 engine. A .45 is probably not enough engine.
