RC Trailer 1/10 Scale by frogfish_42

Last crawled date: 3 years ago

ATTENTION - WORK IN PROGRESS!
RC Trailer in 1/10 scale - customizable
Specs
Will fit an 1/10 scale EP touring car, HK's Swamp Dawg, maybe other vehicles, too
Can be built with tilting ramps or tilting loading area
Reuses a lot of Tamiya TT-02 parts that I (and I guess many of you, too) had lying around

Needs these additional parts for trailer with suspension
Rims+Tyres
Wheel hexes and pins (maybe print this hexes: https://www.thingiverse.com/thing:3677390 )
a bunch of M3 screws
4 Wheel axles, like TT-02B's N2 or TT-02's C3 (Tamiya #19115153/1)
8 Plastic bearings, like TT-02B's BB2 or TT-02's BB3 (Tamiya #10555015)
8 Step screws, like TT-02's MB4 or TT-02B's MB3 (for shocks) (Tamiya #50582)
4 Screw pins, like TT-02's MB5 or TT-02B's MB1 (for arms) (Tamiya #19805573 or #19805755 (the latter is shorter and fits best))
4 Friction shocks, like TT-02 (Tamiya #51528) with kit springs (Tamiya #19805699)
I used the softest springs I could find in my parts drawer: PMM racing dark green, but the stock ones are just fine
Standard-size servo if you want to make a tiliting loading area, like MG995 (cheap and strong :) )

Tilting ramp
2 * Tamiya A12 servo stay
Even more parts
Some plywood:
I used 420 x 200mm for the tilting loading area
420 x 225mm for fixed loading area
TBD x 225mm for tilting ramps

Programming your remote
I like to use a FlySky GT3B or, even better, GT3C for controlling crawlers.
I flash them to get 6 or 8 channels and many cool options (slower like servo speed) out of it. Learn here how to do it: https://www.rockcrawler.de/thread/10395-flysky-gt3b-3-kanal-pistolenfernsteuerung-umbaubericht-auf-6-8-kanal-diskussione/
After flashing the remote and binding, I use this to setup the fourth channel:
Press NAME long to set channel-count. Default is 3, I set it to 6 since I use a 6-channel receiver
I used the CH3-Button on the handle, set it up with pressing REV long, enable "C" and choose channel, set MO (momentary)
Since servos are much tooo fast to look scale, I love slowing them down by pressing D/R long, choose the channel and reduce it to 20%
