Electric gets real expensive real fast at larger sizes, and if you like to fly, you need multiple batteries, or you're spending all of your time waiting for batteries to charge.
Back to your engine. If it's a Saito you're talking about, you MUST adjust the low speed needle. On my 1.80 it took about 3+ turns in to get it leaned from the break in setting. I always get my needles set on a test stand first. On my saito's I peak the HS needle WITH A TACH! then leave it at peak, for now. Lower the throttle setting to the lowest idle possible, then start leaning the LS needle. let it run for a few seconds after changing the needle. Check transition after you lean it each time. Keep leaning until it stumbles on transition, then richen about 1/8th turn. Re-peak the HS, then richen 300-400 rpm for flying. If you don't lean the LS on a Saito, it will idle poorly, run rough, and use a lot of fuel. My 180 will idle as low as 1350 rpm and all day at 1800rpm, and my .40a will idle as low as 1600 rpm an all day at 2000.
