Default RE: Complete Newbie building a GP Skybolt. Idiot?

Marcarleno......I will agree and disagree with you. I'll just make a list.

#1 Strokes are cheaper yes, and they are a good way into the hobby. I personally love my supertigers, but haven't tried one of the newer models since they were released.

#2 2 strokes can be easier to tune, but with a tach, a 4 stroke is just as easy.

#3 Maintence on a 4 stroke is no more than a 2 stroke. After initial breakin, you have to reseat the valves, but you should rarely have to reset them after that. I just did mine for the second time in two years. Saito 1.00 by the way. Havine way more problems is not true. I find I have less problems with my 4 strokes and they are more reliable, but then again I've never tried anything but a saito for that reason.

#4 A plus to 4 strokes, you don't have to retune them every trip to the field. I never, and I mean never retune a 4 stroke unless I change nitro percentage. It's just not needed. Once you get the needles where they need to be, don't touch them.

#5 A 4 stroke can be more costly to repair after a crash, but parts are usually reasonable, and they really aern't that hard to do yourself with simple tools.

#6 Stayaway from the RCV SP engine. The swing such a large prop, I highly doubt you would have the clearance for it. My buddy has a 1.20 RCV SP and it's swinging a 18x16 over 5500 RPM. It is a horse for sure.


I'm sure I'll catch some flak also, but that's what a forum is for.....LOL

just thought of one more thing.....and I'm not sure if this is still true or not, but the O.S. front bearing used to not be sealed, so if you hang it by a tail, you get unspent fuel and oil dripping out the nose of your plane. If this is not the case, please someone correct me.
