Yes, thanks RC Sumo, this i am aware of from reading other posts in here, what i am more concerned about is the added weight, the prolonged flight times are obviously what i am after, but i am wondering what the extra weight will do to the flying. The battery pack i have is only 90 grams, but the larger mah, something like the 1100 is 165 grams, and although only 75 grams extra i have heard this can seriously affect the planes flight characteristics.

Thanks for your reply, have you any thoughts on the weight factor for this plane?
