Hello,

Did some work over the last couple weeks. Mounted the tailwheel and flying wires for the tail surfaces.

Mounted the smoke oil system. I'm using a TME smart smoker on a 4.8V 500 mah nicad. I mixed the radio by retract channel to channel #6. With 5 to 6 mix at 100% the retract switch on the transmitter turns the pump on/off and flow can be adjusted by the flap knob. This control works very well. The pump seems reluctant to prime, small pockets or bubbles of air are passed through but a 2-4 inch pocket of air does not clear. I did make this pocket intentionally to check prime ability. The loop I rolled into the tubing does not exist in the plane. I choose the TME because Sullivan and Slimline both recommend 6V and I have several 4.8V nicads but zero 6V. The pitts muffler is a Slimline with their smoke heater. Oil flows in machined spiral passage that sits in the exhaust discharge. Should pick up alot of heat there plus the muffler volume is large. If smoke is not acceptable I could wrap copper tube around the exhaust stacks. Picked this up at [link]http://www.rcdon.coom[/link].

Tank in picture is fuel mounted on CG. I mounted a Perry carb and pump on the ST 3250.

Paint for pants and cowl has been a problem. A couple weeks ago decided to try and cover the pants with Ultracote. This did not work. Broke the pants trying to remove the Ultracote. I ordered another pair from Fiberglass Specialties. Very nice. Using the old pant for experiments, I worked out the follwing scheme to give an acceptable match to Ultracote Pearl White. Prime using Lusterkote, two coats of Lusterkote white to provide coverage and hiding, two coats of Pactra Pearl White polycarbonate paint then several coats of Lusterkote clear for gloss. The Pactra is meant to be applied on the inside of clear lexan car body. Here the lexan provides the gloss but the paint surface dries to a dull finish. The paints appear compatible, I applied several coats in one night. Now that I got the technique the next few days will be painting the cowl and pants
