Fuel for Brodak .35 Speed Events?
« on: January 22, 2018, 04:02:44 PM »
Question for Paul.  It is understood that we will use 5% nitro fuel this year but will fuels with different oil contents be available or just one for everything?  If one,  how much oil??   Thanks, TS

I will host three speed events:

Perky & Fox 35 will use the fuel that the rules specify.

The Sportsman event is a Brodak-only event without established rules.  I will provide a few different 10% fuels with different oil contents. 
Perky has 20% oil.  Fox 35 Stunt has 25%.  Brodak Clown & Foxberg use 22%.  So if I bring some 29%, that should cover anything anybody wants.
20, 22, 25 and 29.

No.  We will use the published rules for each event.

For Perky, 10-20-70
For Fox 35, 5-25-70
For Sportsman, any blend with 10% nitro.

I have avoided changing the rules of Perky and Fox 35 Stunt. 
Sportsman is my unique event, created at the request of those who want to compete without machining a special Fox 35.

The Max III was a powerhouse for a plain bearing blackfin engine.  Not much good for hot starts, but that's no problem in Speed.  There might be a good number of healthy old ones around, since they were retired by the ST C35 & the G21.

I've got my Sportsman Speed ship all finished. Waiting for clear weather to do some testing. I had some trouble with the decals, as the decals refused to lay down on a slightly curved surface.Has anyone experienced this with Brodak water slide decals? In any case the bird finished up at 28oz rtf. Pics to follow.....Skip
