Dumas 45" Scarab

That being on hold it is time to move onto the rear of the boat. I dug around and found this old school(Hughey I believe) gear.



That is about where I am at with this one now. I am leaning toward making some kind of cover that looks like an outdrive leg or something just to clean it up back here.

Are you concerned at all about the flex in the well nuts?

I thought that was a bonus. A little vibration damping. That is all there would be.
Do you think otherwise Rick? Have I misthought ?

[rickwess]

I've used well nuts in a non-RC application and the bolt tends to "float" a little. Looking at your pic, I can't see you being able to compress the well nut much either. I'm picturing how much a full size car engine moves under acceleration. This won't move even close to that, but this a big boat with a big motor so you have to expect some movement. Aside from having someone hold boat in place in the water while you hit the throttle, I don't know how you could even observe the movement.

The wear point will be where your flex exists the stuffing tube. Maybe assume some movement and think about how to deal with the wear area.

[srislash]

That makes sense. We'll see how it all fits together. Those rails are about 1/4" thick so they should get a firm grasp.

[rickwess]

It'll be how comfortable you are tightening the screws into the well nuts. The tighter, the less float you'll have.

Well this project made it back on the table. I had another boat started for the winter but my custom parts will be awhile I think.
Winter has also had different things in mind for my time, haha!
I changed my mind on the S bend in the flex and redrilled holes for the more standard straight shot. The motor is mounted! I also picked up a 5” extension rudder for this one and got it mounted. I’ll tidy the steering gear next and then setup batteries based on CG.

Well I have this one down to paint work on the lid. I got a UBEC wired in and wired up a Flier 300 for 12s operation. Stuffing tube in, servo and rod in.

Foam in for locating batteries and Rx in. I’ll get a couple more pics. So now I’m waiting on a 1/4 flex and paint and good to go

Oh yeah, built a funky oil reservoir

Wow, that's a blast from the past. And I thought I had projects sitting on the shelf 😂. What size is the Proteus motor you've got in there?

[srislash]

It’s bigger than the 2028 I believe. I’ll go measure.
Yeah I have a scratch built jet boat here too that just needs the gear installed. Built it in 2008 as I recall?? Lol .
Never seen water!!

[srislash]

Alright boys. It took some patience but I think I have a pretty good match on this thing. It needs clear yet.
I still have the cockpit and windshield to do but it’s close

[bogieboy]

Looking real good there!!!!!!! can't wait to see it finished!

LOVE the older hulls ! Great job !!

Gonna hand paint all of those gauges?

I actually have some airplane decals. But i will be doing something.

And thanks guys. I was reasonably impressed with myself. Ive never done any free hand airbrushing.
