Has anyone pulled the front and.middle driveshaft making the truk a 2wd? Power speed gains? Or does the front help drag it along

suburban_hooligan

what truck are you running.
i have minimal experience with this. i did it with an 1/8 nitro buggy and 1/10 nitro touring car about 15 years ago. in both cases, acceleration was slower do to having less grip and top speed was unaffected.

4WD will perform better in every application, simply add more power to get desired speed... converting a 4WD to 2WD is VERY difficult because the geometry will be vastly different... most 4WD go with a 50/50 balance ratio and 2WD's tend to be closer to 40/60 ratio from front/rear.

I've had grub screws come loose on my center CV driveshafts on my 1/8 MTs causing a 2wd only condition. Needless to say, control and power sucked in 2wd - front wheel drive or rear wheel drive. Tirespin was rampant, and control was horrible. I'd not consider "converting" a 4WD truck to 2WD without seriously revamping the chassis. You *will* be disappointed.

in that case you'd want to lock the center diff with either a slipper or spool to get better results, but would also want to move the battery farther to the rear to get more rear weight bias

Totally agree. I had similar situation with 1/8 truggy. I ended up locking center diff so I did not have to worry about front end drive line breakage every run. The truggy was not even close to being enjoyable while running in "2wd mode". I'm sure a 1/10 scale platform will have similar results with extra weight up front.

@ Justwayne: Not sure about why you want to take out front drive line. Like bill_delong said, chose appropriate power/motor combo for speed. If wanting to enjoy a 2wd off-road RC, I'd just go out and purchase one.

I was just curious man if the 4x4 ate a lot of power. Thanks for the feedback it's blackout pro 3s. Just was wondering it did make it wheelie more so like an overpowered 2wd Traxxas xl5.

If you want to make an RC wheelie just put more weight near the rear. Use lead weights, or something.

As for taking out driveshafts to make a 2wd as others said not a good idea one thing they didn't say is it will also put more forces on the rear driveshaft which could cause it to twist/snap. I've actually had that happen once when I lost a front dogbone when I was out I figured just take out the driveshaft, and it will be fine... nope twisted the rear shaft.

FWIW though for me wheelies got old quite fast, and I would then put time, and effort into figuring out how not to wheelie.
