Vision FE Tunnel Build

[sailr]

How do you keep water from going in through the esc wire tubes?

Here is the E.S.C. shelf made from .050" carbon fiber sheet. This will butt up against rear bulkhead. the wires go up and out the top and there is good clearance for any cooling line configuration. Next I am going to copy Kris's tube idea for the esc wires.

12. a lip is installed using scrap glass, once dry I will sand and true it all up straight.



salir, shrink sleeves and goop should seal them to the tubes.


And to all a good night!!

I am going to credit Mike L (cybercxt) for the tube idea...I just made it go through the cowl instead. Also, you wil want to use aluminium tubing (or brass) which your plug (I use 5mm) just fits through. You also need to use the shrink tubing which is lined with epoxy or silicon (which ever it is) this seals the hole properly and also holds the shrink and cables in place really well.

roger that on the shrink...

13. here is something I do to all of my models. fuel dots from central hobbies as drain plugs. Helps air out the hull as well. More crucial for wood hulls.

14. rear bulkhead is fitted and glued in place. Top of bulkhead is approx. 40mm from back edge but I have about a 10degree tilt leaning back to give that extra 10mm or so of room for the steering system travel.

15. Wire tubes installed. Gonna shelve it a week or two til more parts come in.

16. Cooling line access. s.s. tubes will seal using pushrod bellows against the carbon bulkhead. This is the easiest way I could think of while keeping the lines minimal and simple , also this allows for other esc's later on.

Nice work Sandy!

Sorry to be a goofball but...is the cowl mod so you don't need to build a radio box?

[Cat-Boi]

yup. saves weight too. Just makes everything simpler and more roomy.

[teach]

Neat!

[Cat-Boi]

well, ups must have read my mind, because a pair of these showed up today!

I will fit them later this week...

18. I use an anlge finder to make sure my bolt pattern is straight!

19. I decided that 4mm bolts would be just right and this boat does have a transom doubler made out of alu to accept threads... but this is really good for rudders and strut mounts that get bolted down once or twice, but with constant tuning changes in height for conditions and props I thought it would be nice to have something I can put a little more English on. I cut the heads off some 4mm x 20mm s.s. bolts and made up these studs. Now you can use 4mm locknuts with washers to tighten and adjust with the studs taking all the load instead of the alu plate.

20. Here they are installed ready for action.

[Cat-Boi]

Kris, how far foward did you mount your servo from transom?

waiting on parts, should get back on it shortly.

[Kris Flynn]

I will get back to you tonight/tomorrow! At work right now.

I was just about to ask how this was going...you should get you parts from Ray soon.
