Looking for a buggy project

[BrianG]

Yes, the battery trays are bolted only to the chassis. I didn't want ANYTHING on the plastic dirt guards, especially something as volitaile as Lipos. Don't need to be dragging my Lipos over dirt and rocks if the dirtguard breaks! :026:

Anyway, I used some nylon bar stock as a spacer because it is light, easy to work with, and self threads easily. I think I got it from McMaster Carr. It's about 10mm thick and about 20mm wide IIRC. 10mm is the perfect height to clear the dirtguard "nibs" (the little protrusions that the screws go into). Below is a pic of what I mean - the screw placement in the final design is a little different than this, but you get the idea:



As far as canopy clearance, I'm good. The shallowest part of the body is right at the edge of the sides, and the batteries don't go over that far. I still have about 3/4" or more of clearance at the worst spot. However, I did raise the body mounts about 6mm to gain a little wire clearance, so make that about 13mm without the raised body.

Well, after playing around with the buggy a little outside (difficult to find dry pavement with all the snow melting around here - but I'm not complaining!), I am quite happy with it. It is VERY fast...almost too fast from what I calculated. That got me thinking a little and then found that I got the 2d rather than the 2.5d! Lol, that would explain the difference in speed! I may have to drop from a 14T to something a little smaller like a 12T or 13T for cool running this summer.

You should be pushing over 50+ mph with the 2d; you think the quark could handle such a hot motor? Also, was it a shipping error that got you the 2d or you mistakenly ordered it?

BTW your buggy looks really good!

Bye:018:

Thanks! No, I ordered the 2.5. I think it was a simple shipping mistake (I verified my order). Unfortunately, I didn't notice it until I started questioning why it was going so fast. lol. I obviously soldered it up and ran it so I can't just exchange it. No biggie really.

I think the Quark will be just fine, especially since I've added a little extra cooling. I'm more concerned about the batts heating up under the extra load in the heat of summer. I emailed Mike asking what he thought. If it will run a little hot, I'll just see if I can order a smaller pinion to reduce the motor load a little.

Edit: Wow, I already got a response from Mike! He says I should be fine. He's running the Quark with the 1515 1y in his Maxx with no pack heat issues. So, I think I'm all set.
