BBY's 1/8 Pro Boat build

[yurkanip]

Looking good...keep up the pics and build info...can't wait to see it wet. Speaking of shipping damage, I had a similar problem with fedex delivering a broken shovelnose. Entirely the shipping outfit was to blame, stacking my box....resulting in a completely caved in nose on this 1960s Dumas hull. It was easier to knife off the skin and fix the internal bracing, then start from square one rather than fix just the broken nose and work around blending the repair. I am in the process of reskinning the entire hull now...(its wood, obviously). Your boat is looking great, and its fiberglass which is very easy to work with...

The transom damage was from me removing the metal bracing for the POS strut. Not UPS faulght at all, they just cracked all four conors.

This mount feels good and strong I picked up the boat by the motor and shook it, it felt solid.


Strut mount built and installed


Strut in place. This one is 1/4 shaft.

Why not mount the strut to the transom?, Well, I mean the outside of the transom?

If I want to run the boat in the scale class it needs to be whare I mounted it to be legal, All I will have to do is add wings to run in NAMBA.

Ahhh, gotcha. Is it water tight? I'm assuming it's not since you'd want it to be adjustable. If that is the case then the rear area must be sealed from the rest of the hull, no?

Yes it has to be sealed. One of the reasons I hate the rule. I have thought for a long time to build a water proof box around it to seal it from the rest of the boat. But I just put RTV Sylcon all around the strut arm on the bottom of the hull, inside and out.

[j.m.]

So when you adjust the strut you have to reseal it?

Or is the RTV flexible?

[Rumdog]

Might be cool to box it off and add a autobailer!

The problem then is getting to the adjustment screws...

I do not have to adjust it much most of the time so the rtv has enough give .

I got the stuffing tube in yesterday. Too many vistors today to do anything today.

[KillerDave]

Good build so far, I am building a 1/8th Bud' to run Nitro but would love to take on a build like yours!!! Keep it going!!!!

Why three oiler tubes on the stuffing box?

The one close to the motor is a oiler the other two is cooling for the stuffing tube to save the epoxy.

[RandyatBBY]

Little more work done yeaterday.I missed one of the metal Plates in the transom and it took a little longer to drill all the holes for the rudder bracket.

Servo mounted it was a stanard setup good thing it had a good base of FG that I oput it to rebuild the transom and floor of the hull.

I am going to break from this I have to build three riggers lay up one Lift master today. I need some 7071 .125 plate for the turn fin.

It will look like this less the wings for a while.

[Brushless55]

very cool, and I cannot wait to see this motor run!

[tth]

Looks great Randy. I know alot of us are waiting to see what that Big Ole' motor will do.

[RandyatBBY]

Ran the boat yesterday. It looked like it was going to run great but the repair on the Schultz did not hold up and it poped. I will try the CC HV Next or the M-2000 one of them must do it. I am just afraid of the first run CC HV.

[sailr]

I thought this motor wasn't supposed to be much of an amp hog?

[crabstick]

What motor is that Randy?
