gas sipper!
You will love the gas milegage that RCS 1.4 gives you. I ran mine with a 8 oz tank and can get 12 minutes flight with 1/4 tank left. I will be pulling mine off the present plane and installing her on a DA Funtana kit next year. I presently ran an 16 x 8 apc but i think i will try the 18 x 6 and see how that combo works out......
