Please add me to B Hydro - shirt size is L

I am signed up! I thought it was tricky to scroll past Little Thunder to find Spring Shootout. Same name, different club.

Merry Christmas Happy Birthday Kenny!

Thanks Everyone for the Birthday wishes!

I ran my .12 outrigger hydro yesterday for the first time this year. It's such a fun boat, I wish the class would take off! The Sport 20 boats are really pickin up in numbers, and theye look like a lot of fun too. Sport .12 might be hard to find a small enough prop though. I know there are...

Hi Ray, I will take that pipe off your hands if its still for sale?

We had a fun weekend & it was worth the trip. It was nice to meet everyone and see some fantastic running scale boats. Thanks to Marty & Al and everyone else that puts this race on!

I drove a 1992 Budweiser 1/8th scale last weekend. Its a very pretty boat especially in the sun. I can get you some pictures of the model & maybe the paint codes next week if you like. The boat I drove was a T3 just like the picture you posted. It belongs to Mike Board and is currently in a...
