Ty,
Since I helped set that plane up. I feel I can answer that for you. That timer is an FM-7. It can be switched between "SET RPM" mode and pure "GOV MODE". In pure "GOV MODE" one pot is for flight time(2.5-6.5 min). One is for start up delay(I believe 2-30 secs on that one). One is a course adjustment for RPM and one is a fine RPM adjustment (+ or - 200 rpm) so we can make fine tweaks on the flightline without going too far. Since I (Ron also) no longer fly in "SET RPM" mode I can only remember that the Time pots stay the same and I believe the course RPM pot lets you choose between your 3 settings. I do not remember if the fine pot had any function.
  BY the way , I had the pleasure of flying that plane on Monday and I can say that it flew very well!!! Ron has another WINNER here.

Crist,
The wing was cut down and is 51 inches long. My guess is about 550 square inches.

Looks like another winner Ron - WTG!

Thanks Dennis. It's a fun plane to fly and handles like a dream. I plan on bringing it to Brodaks along with "APACHE".

Ron

Ward,

I use 3/4" cup hooks from Home Depot or any hardware store.  White glue is put on the threads, after making a starter hole with the drill, they are screwed into the 3/32 plywood doublers. There is really no pressure on these and the rubber bands hold the batteries in place just fine.
