Hi, I've just helped a friend build one of these. We flew it yesterday and today.

After reading up about tail heaviness, we did the following:

1. Removed the installed engine mount and filled the holes with epoxy mixed with milled fiberglass.
2. Installed a GP 1.20 size adjustable mount for an inverted engine installation (OS .91 Fourstroke).
3. Used a Hitec HS-81 servo mounted in the switch location in the servo tray for throttle.
4. Used Hitec 425BB servos for each elevator half and for each aileron; a Futaba 9202 for the rudder.
5. Tossed the supplied tailwheel stuff and used a Sullivan instead.
6. Tossed the supplied fuel tank and used a 12oz Dubro instead (need to cut a little to get it in).
7. Used a piece of light ply to create a shelf under the engine box for the battery (5 cell 1650mah NiMH).
8. Tossed the supplied wheels and used Sullivan Skylite 2.5". I recommend using 2.75". The wheelpants cannot be used with the bigger wheels.

When mounting the engine, we moved it forward on the longer (GP) mount, so we also had to move the cowl forward a bit. No problems doing that. With an inverted engine installation, the cowl stays looking nice.

Control surfaces are set up as follows: Ailerons: 25 degrees up and down; Elevator: 13 degrees up and down (does not snap when elevator is pulled hard at this setting); Rudder: Set so that rudder is parallel with edge of elevator at full deflection.
Expo: 35% all round. Next time out we'll increase the expo on the rudder to about 65% for more subtle yaw adjustments.

No added dead weight at all. Using a spinner nut, not a spinner.

After two days of flying this plane I can report that it tracks very well, does great knife-edge and in my opinion makes a really good entry level IMAC plane (Basic class). The only issue I have is that the snaps rolls are way too fast. These are not done in Basic, so no problem there. With the OS .91 FS it has more than enough power.

Very good value for $$$ indeed.

Craig.
