Description

The CR3.4eco crawler in Sherpa style is interesting for all those who are looking for purist crawling or want to get into this fascinating hobby on a low budget.

This vehicle is a “downgrade” of our original “CR3.4 RTR chassis which is probably one of the best on the market and has been since 2020!
The quality of the installed parts is of course the same as its fully equipped brothers. The mounting points for special equipment such as the differential locks or 2-speed gearbox would theoretically also be available.

The vehicle comes as standard with a 550 32T brushed high torque motor and a HobbyWing 40A speed controller. You can use “jumpers” on the speed control to determine whether the vehicle will be powered by a 7.2V NiMH battery or a 2S or 3S (low profile) LiPo battery!.

Portal axles not only offer a greater distance from the differential housing to the ground than conventional axles, they also have another positive feature. With conventional crawlers, the torque applies so much force that the vehicle jumps over the obstacle. The design of the portal axles reduces the gear ratio at the wheels and virtually eliminates torque shocks from the drive. The overall reduction ratio of the final drive is more than double that of non-portal versions to ensure smooth running  

The steering shock absorber absorbs most hard impacts so that the 9kg MG steering servo and the servo arm are spared. Hardened steel drive shafts and a steering angle of 45.8° offer the best possibilities for every terrain. Added to this are the 2.2″ tyres, which not only look stylish, but also offer extremely good Grip thanks to the super-soft tyres.
