Scale Scarab 38KV scratch build

[70skid]

Looking good there skid. But, somebody forgot the popcorn..... waiting for this build to hit the water, and hopefully not sink.. stern gonna be a tad heavy ya? lots of floatation . Battery size a concern. when I converted a Dumas gas 1/10 AVL to FE , I made cardboard blanks of the three battery sizes i wanted to run. trying to determine what type of use, race or recreational running... times and prop will dictate which you use , resizing the bulkheads to fit the batteries I chose was perplexing ... since no clubs near so no racing perse' , but SAW is always a throb... last minute changes for battery placement could mean ripping out bh's and reworking that strategy.

It’s always fun modding an existing model, especially interior bulkheads. I’m doing my best to design a flexible layout in the hull for some battery fitment options. I had a stack of existing batteries laid out the other day on the plans. Using my eyechrometer I did my best to eyeball the balance point in the hull. Having the outdrives/motors full aft gives me hope that the batteries will be happiest ahead of the midway point of the hull. It’ll be confirmed soon enough once the physical hull materializes.

2850 motor also saved a lot of weight, a bonus.

Many thanks for the tip!
I'll definitely be looking into this motor option.

P.S. Love the tender. Is there a thread on this model?

Such a cool boat you are doing.

I had the 45” Dumas. There is a thread on here somewhere.

Great build so far.
Some ideas for ya:
Bulkheads: Have you considered fiberglass construction? If you make a model of the hull with all the detail in it you want, it would not be that hard to make a mold of it.
A fiberglass hull will capture all the chines and detail you want. If you make it with a core material like a 3d hex core, even 3 mm thick, it would be quite strong, and really light

Out drives:
Another person on the forum is addressing the durability of the TFL Outdrives by making them work with a flexshaft.
It may not have the look for a purest, but it will have a greatly increased durability, and will out perform the base unit.
