hmm... would anyone like to trade me my .61 mag for a .40... cus i dont have the money to spend on a new one... i do have three radio systems and two mag .61's and the plane came with the mag... i wasnt aware that the tank would be too big ... it also came with a 24 ounce and i went to a 20 ounce thinking the 24 was too big... hmm... what to do... do you think that the 61 and 20 ounce will hinder my learning that much... i mean... will i just learn to use my left thumb and/or take longer to learn... or will i really run a risk of crashing or learning bad flying habits... thanks for all input...
