| The Goliath and TLT are similar in the fact they they are of similar size, and basic layout. But there are many differences that set them apart. Search for "Goliath" and you should be able to find some old threads about them. |

Are you serious? You are just a post padding SOB. TLT's and the PTI Goliath are two non-like rigs. Sure they are both labeled as 1/18th but that's where it ends. If you can't mention any new info, why post. You are not helping. PTI's are based off of the AE TC3 diffs. Same diffs as what the AE TC3 runs. They tend to break when real crawler use it placed upon them. The axles are not sealed from the elements, no bearings/bushings at/near knucle piviot area. It's wide open so anything can go all the way into the ring & pinion at the differential. The transmission on the PTI is a tough little unit, far better than the stock TLT belt driven junk. Sure th 'Pede tranny is better than both but if looking at the two stock units, the PTI unit wins. The PTI is built a bit more low profile, comes with 2.2 tires/wheels... The TLT comes with baby sized tires. If you want to stand out get the PTI... If you want to have a set of solid axles that can handle lots of use/abuse over and over again, get a TLT. Both have their places, PTI was built for general bashing around the dirt field, the TLT was too but Tamiya must have known they'd be great for hard use on rocks. | |

| This TLT vs PTI thing is a dead horse. It's been beaten on many many times. Like Mad Scientist says, do a search and you'll see... However, just to beat the dead horse a little more, gunk doesn't get into the diffs like people think. I drive mine through the water, mud and muck every weekend and have never got any crud in the gears. Water maybe, but no stones or anything like that. The TLT axles have additional bearings on the outter ends so water doesn't get in the axle tubes like it does on the PTI, but the bearings on each side of the diff keep crud outta the gears and I could care less if the dogbones get wet or dirty. The gears themselves have a bad reputation for going bad, but I just recently stripped a ring gear after over a year of use. The ball diffs suck for crawling, but there's a spool that's a direct fit. They just released or are getting ready to release a new 10.5" wheelbase version (there's posts on here about that too) that employs many of the typical mods such as spools, 4" shocks and crawler specific tires and delrin diff gears. PTI has been contacting many PTI owners and picking their brains about the mods we've done and what we'd like to see in the future. It's nice to see a company taking an interest in this niche market. |

| Looking at what comes in the kit, I think you'd be able to build up a decent crawler for quite a bit less than a TLT. No need to pick up a bunch of extra parts to make it work well. Might be worth picking one up... |

| Well, the kit alone is $189. And it has a 10.5" wheelbase. So if you want the standard 12.5" wb, you gotta buy/fab new links and extend the driveshafts. And to make it absolutely capable, you'd need to put a GD-600 in it. The chassis is well suited for a crawler though. Hell, I still prefer my PTI over my TLT. The skid plate on it is less than 2" x 1" so there's very little to drag on the rocks. It's more capable than my TLT so far. I had 'em both out and my buddy, driving my Goliath, who has not experience with these things, was having no problems outdoing me on the rocks. In the end, I've spend almost an identical amount of money on both my TLT and my PTI. |

| I'm using a combination of a 13T on the GD shaft and an 18T (I think) on the motor shaft. I tried 13T on both and it's god awful slow. This setup is just about perfect for me. |

| They've never been plastic. They've always been metal. |
