Well, I'm a Slickless man again. There's a hole in my soul now. Anyone wanna trade an EF 60" Extra airframe for a 59 Slick airframe? LOL
The 51" will fly more like the 71" or 89". The 59" flies a little more "patternish" IMHO.
He has the gear for the 59 it sounds like.
You'd be correct. Although, stuffing a 4315 under the cowl of a 51 sounds exciting....
