Vectormatic Posted October 17, 2015 Posted October 17, 2015 Hi Guys Over in Chade's 1:12.5 scale RC car topic i got into a very informative discussion, and ended up ordering my own PF kit once double points hit my side of the pond. I decided to convert my 42022 hot-rod first, seeing how that is the best suited chassis i have ready-made for this, i might try my hand at modifying 42039 in the future, but im not sure my single L-motor will cut it for a car that size. I failed in my initial goal to keep the fake engine as is (i had the pipe-dream of somehow having it linked up to the rear wheels to it would spin, but i knew that was going to be impossible), but i think it still looks pretty nice It moves quite quickly too, but sadly the steering is rather inaccurate, i think the steering mechanism used in this set is ill-suited to servo-ing, it will recenter well in one direction, but not so much in the other, producing a small left pull. This was a fun first exercise in trying out RC-ing stuff, ill certainly do my own chassis next, but having this one laying about, i figured, why not? Quote
Andy D Posted October 17, 2015 Posted October 17, 2015 (edited) Very nice. I consider it quite an accomplishment to stuff an "L" motor an a servo motor into such a small chassis. Do you have a video of it in action? Andy D Edited October 17, 2015 by Andy D Quote
Vectormatic Posted October 17, 2015 Author Posted October 17, 2015 Very nice. I consider it quite an accomplishment to stuff an "L" motor an a servo motor in ugh a small chassis. Do you have a video of it in action? Andy D The L-motor was easy, once you rip out the HoG steering and the link between the fake engine and rear wheels, the motor slots right in, the Servo though, was another story alltogether, spent a good few hours trying to fit it anywhere, before finally settling on truncating the fake engine, as i said, im still not entirely happy with the steering, but i havent thought of a more accurate mechanism with the parts i have. No video yet, but take it from me that with an upgeared L-motor, it moves nicely, takes a second or so for it to get up to full speed, and its quick, although i havent tested it on longer stretches.

Rishab N Posted October 17, 2015 Posted October 17, 2015 I'm amazed that you managed to cram it all in there. Nice work Quote
Chade Posted October 18, 2015 Posted October 18, 2015 Wow, that was quick. Nice job! Can't believe you got a L motor in there. Are you posting a video? Quote
rollermonkey Posted October 18, 2015 Posted October 18, 2015 Bravo, sir. I too, am impressed that you fit in full RC control without any increase is size on such a small set. Quote
Vectormatic Posted October 18, 2015 Author Posted October 18, 2015 Wow, that was quick. Nice job! Can't believe you got a L motor in there. Are you posting a video? Took me about 4-5 hours, 90% of which was figuring out the steering/servo placement. The L-motor was easy, i suspect easier then the M would have been considering the L has nice side-mount holes, which lined up nicely with the existing chassis. Im not doing a video right now, i dont have a decent filming setup (and i dont want to fumble a phone and the remote with one hand less then needed), and im not yet 100% happy with the steering anyway, ill see what i can do in the coming week though, a straight acceleration video might be easier to pull off.

zux Posted October 18, 2015 Posted October 18, 2015 Wow, a very nice try getting all PF stuff in such a small model. I would suggest swapping gears for steering and see how it goes. Quote
Vectormatic Posted October 18, 2015 Author Posted October 18, 2015 Wow, a very nice try getting all PF stuff in such a small model. I would suggest swapping gears for steering and see how it goes. It is not a gearing issue, in fact, the gear reduction is actually needed to make it steer nice, as the boom steering has nowhere near a 180 degree range, putting a 1:1 ratio in there would result in the servo pushing the mechanism even more.

Kman860 Posted October 18, 2015 Posted October 18, 2015 (edited) Nice job not only motorizing it, but making it still look good too. I know about the steering, even the manual steering is quite hard, and I was going to ask about that. Great job though Edited October 18, 2015 by Kman860 Quote

I know about the steering, even the manual steering is quite hard, and I was going to ask about that. Great job though Thanks! Im pretty happy with how it looks. On the steering, im not entirely sure if i want to try and fix this chassis (which would be hard considering the placement of the engine), or just take this for a relatively OK first project and move on, to either a completely scratch built chassis, or getting 42037, or 42041 (for the B-model). Im kinda affraid that trying to fix the steering on this model will just ruin the characteristic Hot-rod front end Quote
xyz Posted November 3, 2015 Posted November 3, 2015 Hello, I've also made 42022 RC PF mod. Unfortunately I don't own L-motor, so I've used M-motor which is really crappy thing to mount. Mod contains 1x M-motor (main engine), 1x Servo Motor (steering), 1x LED lights, 1x Power Box, 1x RC receiver, 1x RC pilot. Below video and images of my mod. Currently I plan to disassemble this and make RC version of C-Model Truck. https://www.youtube....h?v=BxP1osSGT2U Quote
