My E-90 is my favorite plane, by far. I'm running a well broken in YS110, about 200 flights on this airframe and about 150 on a previous plane. I think the all in weight is abount 8.5lbs.

I fly near sea level and the YS110 has incredible power. I've run Coolpower 30% Heli fuel, but the extra "umph" isn't necessary. I'm running an APC 16x6 prop at 8,900 rpm (about 200 rich of peak) on Powermaster YS 20/20.

I replaced the stock LG with the Bolly carbon fiber FAI as suggested in this thread and that gave me all the clearance I needed for the bigger prop. I also built it with the HD Dubro hinges and larger control arms to achieve good alignment of the pivot points directly over the hinge lines.

This is my first pattern style plane, and I've flown it hard. I've had to patch the wings a couple of times, and remount the LG plate after a couple of hard landings.

Bottom line, this is a Killer plane/engine combo.
