Blazer Marine Sport 20 Electric Build

[InspGadgt]

I used a piece of marble counter top and my 2 Hudy setup boards to make sure I was always building on flat surfaces. I started out using right angle clamps to make sure everything was aligned properly.

I drew a centerline down my 1/8th setup board, marked the centerline on all the frames, and taped it down to my setup board to make sure everything is straight.

Trying to get the curved pieces to hold and gluing on the bottom sheet:

I saw that previously and thought about doing that too. But now that the UL-1 has been discontinued it is going to get harder to get replacement parts for it. I assume you cut off the center nose parts and reshaped the form so it was uniform across the front. I was concerned that might move the motor too far back.

My current thinking is that I am going to build my own cowl. The stock one isn't fitting properly and I don't want to do too many modifications from original until I get more experienced at this.

Yeah, you are probably right. They might become scarce. ...but maybe that means the price will go down! :) They usually want $35 for that nose piece. Anyways, regarding the mod, I wouldn't worry about the motor position too much. It's not too late!! ha ha. It's a proven set-up. Been running it this way for at least 3 years now. The boat has been in the top 2 in our club the last few years and then took a first and second during the nats in June in the first two heats! Then, driver error!

Well I'm getting ready for the IIC now so I'm going to have to set the boat aside and work on my cars for a bit.

[InspGadgt]

What electric class(s) does this boat run in? Where do I find the rules? I'm planning on using the Aquacraft 2030kv motor with 4 cells...maybe 5...what prop should I be running?

[Shooter]

Boat runs good in the spec sport class with the motor you mentioned. 4S. Spec Sport Hydro or Limited Sport Hydro (LSH).

Back from vacation, finished my combat plane, so now I'm back to working on the Whip. Started epoxy sealing the underside of the sponsons since I figured it would be pretty impossible to do once the bottom pieces were on. When browsing at the local hardware store I found some pigments that can be mixed in with epoxy to give it color so I picked up some white. I figure that it will help me see better if I have a good enough coating of epoxy to seal it. If any wood shows through I know the epoxy didn't seal that area. Plus I thought it would look interesting.

Nice idea!

I might build one I have for Limited power

[Shooter]

Cool. Let us know how the pigment works out!

[InspGadgt]

I think it worked out ok...though I may suggest using a different pigment if someone else wants to try it. The hardener in Zap finishing epoxy is brown in color so the white comes out a bit muddy looking. But I can definitely see where the boat didn't get enough of an epoxy coat on the first layer. Other than the color being a bit off I'm pretty happy with it. I need to pick up some new brushes on my way home tonight to finish up. I'm finding I don't like the foam type brushes...they are difficult to work with in tight areas.

Thanks Randy. Yours is one of the threads I've been following. I like the cowl you used in the pictures initially before you went to the Blue Blaster. How well did that cowl fit the curvature of the Whip? Where do I find that cowl?

By the way...never did get to see pics of it finished :)

[TRUCKPULL]

I have a mould for a cowl that fits the WIP 20/40
I am looking into vaccum moulding with fiberglass or carbon fiber.
Let me know if interested.
The one in this picture has been cut down, the flat surface on the cowl is much larger, so it can be trimmed to fit.
