Congrats Buck on your Atlanta heat racing victory. Were you able to maintain your testing setup for the win? IE R-4, 008 HC, 2219 and pipe at 9.5. Thanks again for sharing!!!

I used an O’Donnell 287 glow plug. Added .003” for a current total of .011” head clearance. 60%nitro w/18%oil. ABC2219-19-38. Pipe at 9.75”. Narrowed the front sponson spacing to 7.5” on each side w/1/8” toe in on the turn-fin sponson.

Wow everyone that's more critical setup info your ever going to get. 287 for heat, 9 3/4 to turn that high pitched 2219 and expanded head clearance to reduce that pre ignition look of the piston and head button. Thanks Buck.

Hey!! Is that the boat you said, wouldn't turn? Congratulations on the win.

 

[timothy johnson]

Already got a plan….

Buckshot where did you find the shorter rudder bracket? Thanks Tim

Buckshot where did you find the shorter rudder bracket? Thanks Tim

It is a CMDi Andy Brown rudder bracket that I had in my parts bin.

Here’s a heat from New Orleans last month.

 

[timothy johnson]

Nice heat Buck, wasn't in that one. Great race overall. Thanks for the rudder info, just sold one of those.

Nice start. Perfect water conditions.

By the way Buckshot, Zipp Kits 45 short kit is out of stock. I guess Joe didn't see this coming.
If you wanted a JAE 45 and A K45 for Christmas you may have to wait.
JAE short kit $99. /// Crapshooter $3000.

 

[timothy johnson]

Don't forget Joe and Zipp Kits has a 67/80 JAE short kit you can buy via special order.
The boat also will accept other motors like a KRE 90.

Hopefully the Hammons will have a new rigger available soon as well.

 

[TJ Hammons]

Hopefully the Hammonds will have a new rigger available soon as well.

Soon! The built up sponsons are going together very well! We have one F hydro out in the wild that will be tested shortly, working on a 67 and two gas twins to go out relatively soon as well. It’s taken a little time but the pieces are finally coming together.

After more than a gallon of fuel through it this week, I pulled the engine down this afternoon to see how things were holding up.

+85mph with a stock ZippKits and an unmodified K-45 engine…life is good.

I think your build and years of boating have something to do with that speed ! Sweet !

 

[stefanmackey]

Has anyone converted this to FE?

 

[RaceMechaniX]

There are a few 45 size JAE riggers running FE power. The smaller 21/P JAE is quite a bit more populous from the build volumes.
