This is the latest addition to my electric squadron.
The foam wing is from an old "Miss Poppy" kit that I won in a raffle back in 1976 and never used. It is sheeted with 1/32 balsa. The flaps, stabilizer, elevators, fin and rudder are made from 6mm Depron and sheeted with 1/32 balsa. The controls are from Tom Morris (fiber carbon control rod, ball links and locking clevises) It has adjustable wing tabs, covered with Black Baron - metalflake red, black and white. Here are the specs:
Motor - Turnigy SK3542-1000
Prop - APC 11X5.5 Pusher
RPM's - approximately 9600-9700
Battery (not shown) NANO Tech 3300 4s
Speed control - ICE 50
Timer - Will Hubin FM-7
Lines - 60' eye to eye
Lap time - 5.5 sec
Total Flying Weight 53 oz.
I am very pleased with the results.

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.

What's the wing area of the plane?
-
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".

I've noticed that most of you folks are using screw-in cup hooks as battery hold downs. Now I suppose that's because you know that you are screwing into hardwoods. Yes/No? While at the local HD yesterday I was searching out hooks to Bolt thru the nose. Best I could find was 8-32 eyebolts. Pretty big and heavy, and of course need to be opened up. I'm not sure what's behind the ply in my P' Force but I guess I could find out with my dremel. What say you, Screw in cup hooks? or keep looking for smaller bolts?

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.
