Sitting in the chAIR it fees pretty speedy but the actual ground speed of around 50km/h is not very impressive. Watch the video from amazingdiyprojects for more info:
There is still headroom on the throttle but when flying the vehicle it is apparent that air resistant becomes a significant counterpart around 50km/hand the overall flight efficiency drops.

A maximum practical take off weight test will be carried out later on this spring.
