After years of building Tekno truggies, I wanted to try something new, so I picked up a lightly used Mugen MBX8TE roller. I haven't seen anyone build one of these for hard bashing, so this will be a new challenge.
Tekno stock (left) vs Mugen (right)
Both are 7075. The Mugen chassis is only 3mm thick compared to 4mm on the Tekno, however it doesn't have a bunch of milled out pockets, is wider, and has side bends. Nothing compares to the aftermarket offerings from M2C but it does look like a good stock chassis. It's nice to see Mugen finally keyed the chassis for the steering posts unlike the older 7 series.
Mugen (left) vs Tekno (right)
The biggest change with the MBX8 series is the new beefy arm construction and inserts. The older 7 series always had issues with their arms breaking. The arms come with plastic inserts and they also have carbon fiber as an option.
Mugen (left) vs Tekno (right)
Both are 7075. The Mugen front shock tower design is a good bit lower and the Tekno is a little thicker.
Mugen (left, 4.15mm thick) vs Tekno (right, 6.6mm thick)
Both are 7075. The Mugen rear shock tower has quite a range of adjust-ability in the wing height and the Tekno is quite a bit thicker.
King Headz Associated RC8B3 Rear Chassis Brace Mount (7075)
For whatever reason King Headz does not make these for the MBX8 series, only the 7 series. The difference in parts is the 8 series changed to M4 holes in the gearbox, whereas the 7 series used M3. Associated copied Mugen with their car so some parts can be made to fit, and King Headz makes this mount with M4 holes.
I had to trim the rear section for the proper fitment.
King Headz Mugen MBX7 Rear Chassis Brace (7075)
Again, King Headz does not make these for the MBX8 series truggy, only the 7 series buggy. So, I had to drill a countersunk hole in the chassis for the slightly shorter hole distance.
The Associated mount positions the chassis brace just a hair to the side, you don't go by the original hole location.
And there she is, it's bash worthy now. I like the King Headz design with the captured nut, the nut cannot rotate.
Connected.
M2C made this very nice aluminum steering top plate for the 7 series. Again on the MBX8 series, I had to trim the underside for the proper fitment and drill out the 2 holes that connect to the gearbox to 4mm.
Connected.
The Mugen CVD driveshaft's are only 3.5mm thick. So I discovered the ability to use the Losi LST 5mm driveshafts, much thicker indeed. I also tried the Arrma 5mm driveshafts which is what I use on my Teknos, but they were too long.
I use 2 shims over the stub axle in order to have the correct dogbone depth in the outdrive.
Uses all stock bearings.
Then I used a 8.7mm wide spacer behind the hex, the Losi stub axle is longer.
Connected.
Fits like a glove.
