I looked at your profile. looks like you have some 2 stroke RC experience. I'd say get a Habu from "Parkzone". It's an EDF ARF that looks like it's a quick fix winner with good reviews by nearly all who have flown it and it's cheap for a plug and play jet. Fly it a bunch, if you really like what it's all about, get a high quality composite EDF with pneumatic retracts, flaps, high performance and some level of building or higher level assembly required while you still fly the heck out of that Habu. The composite EDF will give you everything you will get with turbines but it will still be a jumping off point if you have second thoughts and you won't be left with a half baked $$ turbine project if you end up not liking all the fiddling involved. Jets are "attention to detail" projects. Awesome once you get into it, but some guys don't like it. Once you start in on EDF's you will know much more what you like in jets and go from there as far as turbine projects. If you really like the composite EDF and you have a chance to go to a few jet rallies to see the turbines for yourself, then get your turbine waiver on the higher performance composite EDF. You could start in on the turbine project you like, based on what you start to identify with at the rallies, friends, RCU, etc while you still fly your two EDF's to stay sharp. Take it a day at a time, enjoy the process of getting into jets. You will be more self sufficient and will enjoy jets much more if you take it in steps. I think you can do it from start to waiver in a single season (two seasons for sure) if you are motivated, fly a lot, are ready to work and are already experienced in the fundamentals of good flying skills and decision making. Have fun!
