You'll get a better result if you clean it before sanding. Don't thin the epoxy. open the crack a bit and clean it again. Acetone works well as does fuel alcohol. cut your pieces to fabric and test fit them. brush on neat mixed resin and fit the first of your cloth pieces. the rest of the steps...

Just thought I would throw this out there..... Venmo is another person to person payment method. You know that they are owned by PayPal. Phil

The epoxy film is amine blush. easily washed away with a mixture of ammonia and water. wash it before you sand the epoxy or you will drive it deeper. Having glassed decks on full scale hydros, I've worked with gallons of the stuff.

The material of the fins and rudders have changed on the U boats too. Look at one up close, they are beefy to say the least. Most of the turbine boats are running a huge fin. Width of the fin has been growing and growing as years go by. Anchoring hardware are at minimum 1"d and high tensile...

There is a ton of excellent information in this article. I have experience in the full scale hydros. (S, E,A, F(NM) and GNH) The same factors we see on the scale hydros also have an effect on the big boats. A couple of things to note: The turn fin must be stiff and unyielding or it will unload...

One way to find out would be to talk to Dave Villwock. He drove the T4 (I believe) and would know when the sponsons and shoes (those rear things) changed. Dave is on Facebook and is very likely to respond to your questions on the hull configuration. Phil

I would contact Dave Williams at the Hydroplane and Raceboat Museum. Dave is the curator and GM HARM in Seattle. A very nice guy and I'm pretty certain he will help you out.

Olav AAen was the master of 2 stroke snowmobile engines. You might look at aaenperformance.com to see what they might say.

It was likely your air pressure and the reducer you used. Reducers are temperature specific. The boat looks great!

Thanks for allowing me into this forum. While I'm new to model boat competition, I'm not at all new to race boats. At least the full size ones. This is one that my partner and I currently own. Built in 1987, it's of the 7ltr class now called GNH. But, the travel to transport it to events and...
