Micro Rock Crawler BTA using stock parts While taking pictures of the DP torsion chassis, the light bulb went off, and in 10 minutes I had the BTA mocked up, and a half hour later it was together. Thanks to Papa Snachez and his TBit2 build, for showing BTA with an aftermarket servo and custom steering links. This set-up was possible because the DP chassis allowed me to remove the front shock mounts. It may be possible to move the servo up and make a custom link to run BTA with shocks. YMMV. The spacers I used came from a helicopter hardware set I bought at my local Hobbytown. Here is the specs from the package: Align, www.align.com.tw, AGNH1150, Hardware Set, #H2027T, $3.99 The steps: 1. Cut off the shock mounts (I used wire cutters) 2. Remove the servo and steering link 3. Trim the bottom of servo horn 4. Reorient steerng link so it faces down and right 5. Attach steering link to back of servo horn 6. Rotate servo 180 and reattach one hole up 7. Flip knuckles 8. Add spacers between knuckle and steering link 9. Reatach stering link (the hardest part, I needed to file the one hole slightly larger to get it to pop onto the ball on the knuckle. 10. Enjoy how great it crawls And on to the pictures!

I wish that my 2.2 would run as well with a $25 investment (chassis, hardware, and shipping). :) |
well this is why I think this rc micro crawler is the best , cuz so ship to do things to it and you dont have to get out of the house, you can do this in the roon and have fun... lol |
im gonna have to disassemble my new torsion chassis to put this in?:x |
Thanks for taking the time to post how to do this! I've been thinking of shaving the screw off the rear axle too. Have you noticed any weakening of the axle without the screw? Quote:

IMHO, it's very worthwhile to shave the axle housing to make it slide over terrain easier. |
