wizzbang 2 was again home built electric (not rocket ) bike way before you could buy them in shops. it is about 8 long and was a pig to get to work well . did get gold medal and robot of comp award. Miniwizz a year later 5 long and also the same medal and award. i still am very proud of that. it was a big shame they stoped teckno games it was great fun and so many types of bots. you had to be at the filming it was chaos. (derek and val again). oh i forgot about wizzbang 1 that was powered by a petrol strimmer engine the steering servo broke and went straight on at the first corner, if you look closely at the footage you see me and a fireman chasing after it !!
