I built one of those GP extra's years ago. It was a great flying plane. In fact at the time it was one of the best I had ever flown. It was a little heavy though compared to todays standards. Typical of the older kits. If you just want to fly around and do some advanced aerobatics, it will be fine. It was not designed to 3D. It was designed before that era. The ailerons are too small and it is too heavy. I had several different engines in it, but a Super tiger .60 was my favorite. a good ,90 four stroke would be a good choice. Enjoy the plane. You will like it. Also, good to see you wanna build. Not much of that anymore.
Also, your list of planes is perfect. The Kaos before the Extra will be good.

I thought Karol would join in on this one. As speed mentioned, a lot of people have been using gassers in there 60 size kit built Extras, usually the DLE 20 though, it's just a gas 1.20 engine. Karol and I both are lucky enough to have the old Goldberg 60 size Extra kit built planes, his is gas and mine is glow. I used the YS 1.20 in mine and I think Karol is using the DLE 20, it could be the 30? This old kit is a 68 inch span and one of the better flying Extra ever built. The kit does show up on ebay once in a while but a few mods should be made when building. The GP Extra kit is my second choice and is also a nice build. I once had a Creek 1/4 scale Extra and found no difference in flight between it or any of my others. Mater of fact it was the only plane I could do a rolling circle with. I think it was because I didn't care at all if I crashed it. As nice as it was it was just a used ARF and I flew it as such.

Some very good advice here. Looks like you're on the right track. The Extra 300 has always been one of my favorites. This past fall I got one from Horizon that has turned out to be one of the planes I take to the field nearly every weekend.

This plane is very reasonably priced and put together well. Mine has a Tower Hobbies .75 and flys great. I would suggest an OS 75AX with a Bisson Pits muffler.

A lot has to do with ones ability too. I started flying in '87 or so with a Royal 40H. next was a used VK Cherokee then against all recommendations #3 was a Pica Duelist. 26 years later I still have all three planes. I flew and rebuilt that trainer more times then I can remember, has to be well over 1000 flights. A few wing repairs to the Cherokee over the years as well. Wore out the original Merco 60 duel plug till it free wheeled. The duelist is ready for a recovering if the oil damage isn't too bad.

I few the first two till I was almost bored to tears but I took my time and felt comfortable with the next choice.

Take your time and the extra should be fine after the Kaos.

I say go for it! Get the Extra and have a blast! Then get the glue and covering and replacement parts out and have a blast fixing the Extra. All kidding aside, the advice already given here is good stuff. If you want an Extra, get one, but get HELP with it, and it will be fun to fly for a long time.

Thanks for the advice everyone, I will most likely get the .40 size kit and then get bigger planes once i get a job lol "I'm 15" KaP2011 I noticed your from Calhoun, were only about 15 minutes away, where do you fly?

I fly at the Dalton RC Flyers Club in Dalton, been there going on 3 yrs now. I'm working on getting a field in Calhoun that's only 10 miles from my house. Where do you fly?

I joined Taildraggers in Cartersville/Euharlee about this time last year, definitely let me know if you start a club in Calhoun, where is it approximately?

Sent you a PM.
