Jolly I guess we were posting at the same time. The LT-40 was almost bought instead of the LT-25 that I ended up buying. I don't think you would regret finishing the LT-40. And flying a trainer is fine with me. I don't have anyone I need to impress. Plus I like to let interested people get a little stick time if they are interested. Nothing like a self correcting trainer to make a new flyer get a taste of model airplanes. Plus I just don't like to have to correct a plane constantly or turn around every few seconds because my speed demon has crossed the sky and is getting out of sight.
When Balsa USA came out with the 1/4 scale J-3 cub I had to have one. The kit was $90. (about 1979) That should give you an idea of how long ago that was. I flew it with a Kraft .61 for power. I would trim it to fly in a big circle over the field. I would set the transmitter on the tailgate of my truck and walk around and talk to the other flyers while my plane cruised the sky. That was fun. It would fly like that until it ran out of fuel.
Only once did I have an incident. I forgot about my plane and it was nowhere to be seen. Finally some one shouted "there it is". It had made its way east of the field and was out of fuel and in a thermal. I had to tilt the wings to figure out if it was heading away or toward me. If it had been a smaller plane we would never have seen it. Thankfully I was able to glide it back and landed it right in front of me. I was a little more careful after that.
