2 points, first, see RC wars thread for my opinions on the above,

second, tantrum was mechanically limited by running on 1/4 voltage. If thats not good enough for some people, perhaps you can suggest a better way of limiting its power than limiting its maximum voltage? Just asking, as the comments seem to imply Tantrum was inspected and it was clear I was at 1/4 throttle... which was not the case.

oh, Ewan, dont get your hopes up, that doesnt look too secure. Its not the supports Im worried about, its the way its connected to the motor. But, you could always run without a weapon..

oops, forgot to address the roof issue, there isnt one.... an issue that is. end of.
