Default RE: New Pentathlon Flies!

Hi Wayne,

I'm planning to go to Sheffields barring any unforseen difficulties, so I'll see you there.

The gasser conversion runs a Walbro carb and since I didn't change any bearings , I'm using 16:1 oil mix.......puts out a pretty gooey black exhaust. That is the downside for me. I'm used to electric with no cleanup....but hey it's no worse than a nitro slimer.....
I'll attach some photos of the motor. The conversion is pretty straight forward:

Drill a hole in the thrust washer and press fit the magnet
Drill and tap a hole in the crankcase for the walbro pressure line
Drill and tap the walbro stem to hold it in the OS case
Mount the pickup sensor on the front of the crankcase.

Optional: Solder a tube on the front of the carb to extend the "neutral pressure port" to just over the carb intake....recommended by Duarte who has been doing this a while.

I've got another one on the test stand now...so if you wand any specific pic's let me know and I'll take them.

George
