You say your twinstar wouldnt fly with 25 la's.. well it turns out i'm the guy that bought it and it had 40 la's but you lied to me about the fuel tanks cuz there were 6 ounce tanks in it and you cut the upper spar destroying the wings complete structure!!!!! plus you had so much glue it must have weighed 50 pounds!!! i own 7 twinstars new and old and best power source is 25 la's or fx's one had 46 fx's and crashed when wing disintegrated on 3rd flight!!!
