ok. one question. what does seal the gap of all the hinges with clear tape mean?  ill do it, but im not quite sure what it means. all this is good stuff, im copying and saving it all! oh, and im pretty sure i have 2 3/4 wheels on the  back, and 2 1/2 on the front. should i go bigger? i got what the instructions told me to, but experience beats general instructions any day, so tell me what you think. you guys just dont know how much you have already helped me, and i appreciate it so much.  i want this to be the the best plane out there to train on, and to be able to use it to help others get into this hobby in the future.
