Your first 1 or 10 planes may not last long while you are learning, but their life starts to get longer as you get better at the sticks. Although, at 7 years in i still make some stupid mistakes and fly them into the ground or a tree will reach out and grab them. The very first plane i bought was a mistake, a warbird that never flew except out of my hand and into the ground. Then i found rcpowers, i built an su-30 and it flew, i was so proud of myself, it lived maybe 20-25 flights,by the time i retired it it was mostly hot glue.
I built a few more planes and destroyed them, then i built a profile Mig29 out of coroplast/corflute and it was virtually indestructible, yes the nose crumpled and the glue gave out but it was easily fixable.
I also built another rcpowers plane, an Su-34, it was such a sweet plane and here we are 7 years down the track and i have only just decommisioned her, took her electrics out today and hung her on the ceiling. She would easily have 100 flights, it was always my favorite plane, like my first plane, lots of glue.
I am currently working on build number 63, honestly i love building almost more than flying.
Keep em flying people and have fun
