I've built and flown two of the Phaeton 40's and two of the Phaeton 90's but quite some time back. I do not recall any problems with the die cutting or anything else. They are not a beginners kit, you need a little experience or help if this it your first kit. All flew great, had a 1.20 on the first Phaeton 90 the put Quadra 72cc on the second. Both were a ball to fly, especially the overpowered (and beefed up landing gear and firewall) with the big Quadra.
