HPI Wheely King Build

[whip]

Thanks for the kudos, guys.

The Wk has gone through a couple of changes since I last posted. I will try to get some pics up.

In its first comp, it did pretty good (third place), but I had to deal with a lot of torque twist. If I got rid of that, it would be a lot easier to drive. What would happen is that while driving up steep inclines, the front left tire would float up off of the rock. Nomally, you let off and tap the throttle and it sets the tire back down, but my twist was so bad that this didn't work. During the comp, I had to change my driving style just to eek by several of the stages.

So, to help reduce twist, I have increased the shock angles. But, of course, while it was all torn apart, I decided to go with the new rave of running without coil-over springs. This limited my twist as the front tire now drops via gravity, but now my chassis lays over... so I am going to either put some limiting straps on the rig or use a single spring in the right rear. I also plan on using a super light oil on the twist side of the rig. I will let you all know how it works.

I had the same problem. I ended up running more shock spacers on the right side of my truck. It didn't get rid of the problem but helped. I think possibly running thicker oil on the right side might help too.

Offset your battery to the left side of the truck slightly and maybe stand up your steering servo.

how easy did the ae mgt arms fit to the original upper mount?

Here is a closeup of it that was buried in this thread several pages ago. It worked great and to this day hasn't broken or come loose.

The Integy MGT suspension arms came with set screws to secure the pivot ball, so I just used them to secure my new bolt.

The inside width of my shock tower chassis was slightly larger than the hinge pin portion of the suspension arm, so I just shimmed it.

Just finished reading this thread.

Excellent. Learned a lot from it. (Understatement)

Well done.

This looks like a really good way to build a cheap crawler. I only have one question. Where can you find the shock towers that you used. I've looked for a while and can't find anything like it.

I was thinning a mono ball type of upper arm mount would be a great way to go. I LOVE the use of parts from other cars/trucks. Good work.
