Printed out a radio box for the scale.

This was my most recent 3D printed project. Turned out pretty good and performed as designed over the weekend. No water intrusion at all. Even after being upside down a couple times!

SAWEET
What make hull?

 

[longballlumber]

It was a used Velasco that I purchased and pieced together for my first scale. I will get a picture of the full fitted and installed box tonight

You doing it as a U-4 or a 7474 hull.
Look forward to pics.

VERY cool Mike! Did you weigh it by chance before you started fitting parts?

Awesome Mike !
Did you use PLA ?

the original builder did the U-13 Miss Natural Light (MHR 7474)

i didn’t weigh it, but I wouldn’t expect it to be that much different than a wood box…. If anything a little lighter. I did add some wood squares for additional taping surface area.

PETG+ is what I used.

My short term experience... The answer is no. I did coat the outside of the box with epoxy, but that was more to make sure it's water tight.

Long term is unknown. I have parts on my 40 hydro that regularly see raw fuel and I haven't see any issues yet. Fingers crossed.

Mike.. take a length of filament and place it in a fuel sample.. let us know. I will do the same with the TPU I have been using.

Mike, what is tucked under the throttle and mixture servo? A voltage regulator?

Hey Tyler, It is. I am using a Lipo RX pack so I didn't want to feed the throttle and 3rd channel too much voltage.

S9650's and S3150's are really sensitive to voltage. I have burned a fair number of those out even on the old 5 cell NiMh packs. I am running an old Castle CCBEC to drop the voltage to 5V for boats that still use those servo's.

Found a PETG chemical resistant data sheet
