Beginner Giant Scale RC Questions, Let's hear them

Higher octane, no ethanol. I personally don't find it necessary. I run pump premium and where I live it all has Ethanol. Never had any issues, but I don't fly as mush as a lot of guys.
To each his own as they say.

Same here.....premium auto for me. No issues whether I fly a little or a lot.

Avgas is supposed to have a longer shelf life. One engine guru here claims to not have carb issues or tuning issues after a plane sits. He has a lot of planes that he rotates through his trailer, and they all run great. I personally don't use it though.

If it evaporates it leaves a lot less crap behind then the standard pump gas we get around here.

Ok, i am a beginner giant scale builder, and a beginner kit builder. I recently aquired a ziroli p47 - 92" wingspan. Any particular hints,tips,tricks from people that have built this or something similar? I already have one wing half and the fuse formed up. From what i have followed with other build logs on this, i see people glueing the balsa sheeting together before glueing to the wing or fuse etc. is there a purpose for this or just personal preference?

Gluing the sheets together before you install them on a wing for example makes it much easier to sand the joint smooth. Otherwise you are trying to glue and sand where you have very little support. A fuse can be a different animal. With all the curves smaller pieces are needed, or even planking.

So I have heard that if I use Ethanol it wont hurt the engine but does not give as much power. Is true? I also see that it's a bit more expensive so not sure of its worth trying.

Thanks Guys.

Where I live there really isn't any choice. There is Ethanol in all the fuel around where I live.

I doubt the average guy could tell much of a performance difference.

Thank you, good to know.

I'm the same way, not much choice for ethanol free. I try to find a gas station that's always busy so that you know their gas is not sitting unused for long periods of time before you get it.

Plane ol 87 at the pump where it is the cheapest. DA 120 likes it EME 60 likes it DA 70 should do fine too once I get it running.
32:1 for all of em too. I happen to like redline oil.
