BBY's 1/8 Pro Boat build

[RandyatBBY]

This is the start of the build for a Sport Hydro to run against the gas guys. I wanted a hull that I did not care if they got excited and ran me over again. This Pro boat was aquired on RR for the price of a 8L Hacker motor about four or five years ago.


Hear is the motor that will be pushing the boat. Retail $169.00 from me, so this will be a inexpensive build. Not sure of the ESC I might use a China 180 or 200 model. I have two 40.160 but one is going back for repair.

Yes a big chamber! I will be building the hardware tomorrow. I am going to test the bottom as is in Primer I think that the botorm will need to be modifyed to keep from blowing over at high speeds.

Any updates? I am looking forward to your build thread, to continue.

I am still fine finishing the hull. I sand blasted the paint off the hull and Patched the rough parts with Epoxy resin and Milled CF with a small amount of Cab-o-sil. Then I have been Bonding the surface for the fine finish. I filled the Pro Boat strut mount with the resin and bondo. I probably should have taken some pictures of the bondo area. Sorry I forgot. Durring the finishing I re primer I do have a few pictures of that. I sprayed the top yesterday and the Bottom today.

Rough spots like this will be bondo.

I am still thinking about that not decided yet, It will be run in the Gas Sport class so it is a little open.

I have over 130 boats and 40 to 50 cars. It is packed a collection from 1985 and I hate to sell anything. Oh and that is just my sky light.
