Here's THE deep-dive on Rlaarlo's biggest model yet: the licensed Mercedes-Benz U4000 Unimog 1/7 RTR (brushed). *See NOTES below for updates since publication!* This is 1/7 scale, but it's the size of an SCX6 - AND you have independent remote diff lock! This thing is feature-packed. How's it drive? Let's find out...
BUY
- Rlaarlo Unimog rlaarlo.com/pages/unimog-u4000?ref=RCTNT
**Servos (see NOTES below):
- AGFRC 62KG 4S Servo amzn.to/3StxkmT (great upgrade)
- HobbyPark 100KG 4S Servo amzn.to/4oABm9a (super overkill)
- Clamping Servo Horn amzn.to/4a25gx6 (not needed with the above servos)
NOTES
- 7:22 Photo Credit: MotorTrend
- Bed is 0.8mm Stainless Steel!
- 13:53 **release version apparently has 60KG brushless servo instead of the 45KG coreless servo in my review unit - EXCELLENT!
- Transmitter language: Phil (@TomleyRC) has released his U4000 and I understand from commenters that if you hold the LAMP button when you power on the transmitter, it'll change to English. Neat!
- Rlaarlo supplied this unit for review. I did not pay for it. But opinions and observations are purely mine; this manufacturer never asks me to say (or not say) anything, which I appreciate and applaud.
--
Regarding the FOLLOW ME function we all saw in Rlaarlo's video a few months back: they showed the "follow me" technology in use, but it was not clearly communicated that this was not related to the demonstration model in particular.
That it is a discreet device rather than part of the U4000 was not clearly communicated, but I've seen Andy say that this device is intended to fit most models. I wish I'd thought to address this in the video as it seems this was a common expectation!
There is no "follow me" automation in this model. Hope this helps.
