As would be the steering. Through the chain drive results in high frictional forces which the steering mechanism can only conditionally affairs. The shaft on which it operates the steering is badly stored.
This steering reacts very late.
The chains, the feature of the vehicle are, unfortunately, also performed very poorly.
On wheels was completely waived. There are only two pinions on which the chain runs.
As a result, the vehicle is moving accordingly bumpy. (On smooth floors, the chains do not move)
Price I would classify it as rather expensive, because only 15 more expensive cargo aircraft is operated electrically.
