Komatsu D65WX-17

Why go for a Komatsu D65WX-17 with 6 way blade? The answer is simple: Since it's a unique experience to operate this INPAT blade which increases the often described fun factor drastically. The entire model is built in modular design wherever feasible to facilitate the assembly at client's end as far as possible.Certainly, the drive chain which requires close to no screwing represents one of the highlights. The pinions are simply secured with the aid of feather keys and only the track drive still need to be screwed conventionally. Both drive units are thus kept very simple and solid. The drive itself can be achieved either via brush motors in order to be able to make use of the popular ServoNaut M220 regulator – which is also used in our prototype – or by brushless external rotors.

Both types of propulsion run a planetary gear which sets the track drive shaft to rotation via a primary reduction and are thus transversely mounted. The entire hydraulic and electrical units are separate components which can be assembled easily outside the model and then be placed inside in one piece.

The hydraulics make uses components such as the "whisper pump" designed by Martin Kampshoff and valves designed by Ulrich Meinhardt. The cylinders, on the other hand, have been developed exclusively for this dozer. All cylinders for the 5 way INPAT blade are gimbal-mounted due to the nature of the system. Obviously, these cylinders can be dismantled easily (if ever needed) since their heads are screw mounted. The cylinders consist of a cylinder barrel of 12 mm external diameter and 5 mm plunger made of approved chrome-plated material.

The bodywork is very detail-oriented and has been provided with a  partially  3D printed parts. These are already pre-treated for varnishing and has finer glass reinforced plastics (GRP). The single web metal chains were also produced exclusively for the Dozer.

The models shown are equipped with attachments that are sometimes not included in the delivery.

The kit includes all the components. The complete hydraulic are included. 
To get the model ready to drive you need the following components: 
Brushless controller for the pump motor (eg Robbe Roxxy 930) 
ESC  for the track motors (eg Servonaut S220) 
Servos for the hydraulic valves (eg Hitec HS81 or similar) 
Receivers (at least 6-7 channels) 
Battery pack (eg Lipo 3S 2400 mAh) 
0,5l hydraulic oil
