Kit build
A year ago I started in the RC business because, like you, it was a scratch I had to itch. My first build was a Sig Kadet LT40. It was a great experience. Very detailed build instructions with nearly all the parts in the box. I put an OS Max 46 nitro motor on it. It was not a cheap experience but very rewarding when it was finished. And, it's been a great trainer to learn with. I've crashed it a few times but the fixes have been relatively easy. Highly recommend that you get a computer simulator and flying instructor to assist in starting. My many winter hours on the simulator were not wasted. I'm a newby but thought I would throw in my two cents.
