Grim,

Did you notice that they had typed the kit number (900) in the border? Nobody would take the time to do that today.

Carl,

I suspect this is kit Number 900.. not the 900th made.

I am friends with Ed Rogala so I can ask him.

 

[Carl Van Houten]

I would be surprised if they sold 900...

I wish I had kept all of the magazines I had but dang...they just pile up everywhere. I did go through them and cut out some ads of mine before I threw them away. Fun times for sure.

They seemed to come out of the woodwork back then; the Dumas Hot Shot, Midwest Klampon Kai and possibly the Hughey all came out about the same time.

I still have a Dumas Hot Shot (the glass one after the original blunt nose) that I am building now. I bought it in the early 80's. I like the sort of scale open cockpit look. But I do not like the cowl. I went through the trouble of making a plug, and molded a few cowls for the boat. The boat looks better with the new cowl and it is lighter too

The next step is to change the tunnel depth and AOA. I am making a plug for the sponson riding surface. The sponsons will have more dihedral

I have a 1966 America’s Hobby Center catalog. It has Dumas boats in it but no Tunnel Hulls. Ocutra White Heat V 42”x15 1/2 “ $ 29.95. GEM Fiberglass Boat kits.

66 is way to early

Did anyone else run a Fugi 15 Outboard before K&B came out with the 21? I stuck one on a cabin cruiser called the Avalon. I think it was about 25" long or so.

I think Jay Shelby had a Fuji. I never saw him run it, but he mentioned it to me once.

Thanks Grim.

This is my Sprint 7.5 built in 84 and invoice of the K&B 7.5.

Cool looking old boat.

I had a Klampon Kai. I thought the Dumas Hot Shot was the first production Tunnel.

KK was after the Hot Shot

I put an out board On a JVS CLAIM JUMPER. Took to my first race in Dallas with FIRST QUARTER WAVE STUB PIPE and took 2nd.

No one had seen Quarter wave pipe on an out board. We were flying Quarter Midgets with quarter wave pipes and though it work on the outboard.

Clee Moreman helped and engineered it.

Clee’s name is on the IMPBA EXCELLENCE OF PERFORMANCE TROPHY

Couple of months later someone did an article in Flying Models on the pipe. Had pictures of our set up. The author implied he had come up with the idea.

Just some historical musings

Not to hijack thread but does any body know what brand of boat this is. it was my first one around 82/83 era. I was about 11 years old. so I don't remember what it was

 

[Jerry Dunlap]

Looks like a Prather 20 Lap Cat.

[Grimracer]

If its "orangeish" inside it could be a prather.. hum.. I am not sure what that is.

Grim

 

[Kez]

I do not think it is a Prather. The nose and the cowl are different. Also the sponsons looked too deep to be a Prather.

The hotshot fiberglass actually runs well with a stock k&b 3.5
