I had a lot of fun running my TLR 22-4 2.0, so when Team Associated announced the long-awaited successor to the B44, I knew I had to get one. What you get is a car completely different than the 22-4 2.0, and much more like other 4WD buggies on the market.
Overview:
The B44 was Associated's first 4WD buggy, and was basically an offshoot of the BJ4 prototype buggy. It lasted a long time in the Associated lineup, and there have been rumors of a new platform for literally years, but nothing showed up. Finally in early 2017, the B64D was released. It's an all new, thorou ..read more

I spent a few hours at the track testing some stuff. The initial plan was to work on my B64D, but I also wanted to test the plastic steering knuckles on the Hyper TT, so I started with that kit.
(Boiled) plastic knuckles held up great, and removed a lot of slop, so I'm going to stick with that and just keep extras in my parts box. I also tested 10k rear diff oil and 5k, still not sure which I like best. 10k gives more forward traction and stability, but loses a bit of steering. 7k is probably going to be perfect.
But I tested out one change that made a MASSIVE improve ..read more

I spend a few hours at the track testing out some springs for the 22T 3.0, some diff fluids and front springs on the B64D, and I also tried out the one-way clicker for the 22-4 2.0.
The one complaint performance-wise I have with the 22-4 is that it doesn't like to land cockeyed on one wheel. The one-way clicker works by allowing the front wheels to freewheel (or at least rotate at a faster rate than the rears) under deceleration, or when landing jumps. This smooths out the landing if you're off throttle, at the cost of straightline deceleration.
Overall, I found the buggy to be m ..read more

I ordered this kit back in December, and amazingly it showed up on my doorstep the day after I got my 22T 3.0. I didn't plan it that way, they just got released basically on the same day.
So I put together an unboxing video. Got tires glued up, just need to assemble the kit now ..read more

I had a very long day, driving 4 hours through a snowstorm to get back from a ski trip, unloading the car, car wash, and helping my parents move a projection TV from upstairs to the garage. But I managed to drop by the local hobby store and pick up the brand new TLR 22T 3.0. I liked my 2.0 a lot, and sold it in preparation for the 3.0, so I'm super-excited I was able to get the only one at the shop.
I shot an unboxing video, it probably is going to suck, but oh well, it's a one take thing. What, you think we do more than one take at Razor RC? Don't confuse us with t ..read more

I did a little more testing with the Hyper TT yesterday.
I lengthened the wheelbase another mm by moving the front arms (top and bottom) forward another mm which helped the stability and overall ease of driving. I also am running a little bit of toe out which helps immensely in the small, tight U-turns.
Not sure on how many degrees of toe out, it was 1/4 turn of the turnbuckles from 0. I try not to use toe out if I can at all avoid it, but I don't think you can on this truck. It just doesn't have enough steering lock and Ackermann.
I also dropped ride height to 27mm front ..read more

I have a couple more videos posted today. The first one shows what it takes to get to the heart of the beast, the spur gear inside a TLR 22-4 2.0. Remove the servo to change out a spur, say what?
The second video is a review of the Sanwa MT-S. The nice thing about videos is it's a lot easier to show something, rather than talk about it ..read more

Video 2 is up! It's a walkthrough of some of the steering challenges that the Hyper TT poses.
That's about it for the Hyper TT for a bit, the next couple of videos are going to be radio reviews, since those are the most popular hits on this blog. Look for an MT-S review first, and then a 3PV review after.
For those loyal readers of my blog, don't worry. You guys get to read about all the good stuff first before I make videos about it ..read more

I was using Traxxas turnbuckles as an upgrade for my Hyper TT, but I recently switched to Associated B5M links. They clear the servo saver a little better when the suspension is compressed at full lock. The Traxxas parts were binding a little bit and restricting full steering throw.
Here's what it looks like:
I happened to have an extra set of titanium B5M turnbuckles, but here are the part numbers if you want to build your own.
ASC6263 - 2.06" turnbuckles
ASC91453 - HD ballcups
ASC91048 - 8mm ballstuds
ASC25612 - M3 locknuts ..read more
