I learned everything I know on bluecore foam.. Go to hobby city and buy a complete power set, a rick of foam from lowes, an exacto, and go for it..!!That helped me alot.. From there I graduated to 2 .40 size katana profiles, a hangar 9 funtana x-100, now I am flying 100cc-150cc on the deck.. I just graduated in baby steps.. There is a lot of good advice on this post and many pointers and tips.. But here is the best tip, FLY !!!BURN GALLONS of fuel. I also learned set-up is critical.. My extreme flight 110 yak would always fall on the nose in a hover and I had to fight it every flight. Moved my batteries back 4" or so and now pop it into a wall and it stands there.. I learned the hard way as I was the only guy in the club trying 3d that bad set-up can make a good pilot look bad!!
