Well, after reading all the advice and re-reading your question and monetary circumstance, I'd say if that is what is in your budget then go for it. Like Jaka, I've got a lot of years under my belt so I feel that I can give some informed advice. I built the PT40 and it is an awesome plane. I eventually gave it to a club member for his son and I believe they are still flying it. Granted, you probably could get a friendlier engine but at a higher cost. I have a couple of SuperTigre engines and there is certainly nothing wrong with them......they have been around a long time.....they just take a bit more breakin, but that will teach you something and yes it is more powerful than you probably need but that is what a throttle is for and it can go on future sport planes as you move forward. As for batteries and props, yes you can get better but they are the least expensive things to replace and the combo seems pretty complete and you say you have help. This will help you avoid chasing around for all the individual pieces and getting back to your initial question and your response this seems like a good combo with a proven airplane and a good brand of radio gear and if it fits your budget and you want to jump in then I'd repeat myself and say go for it!! Hopes this helps amid all the other advice you're bound to get.

Cheers,
Andy
