.12 class racing project
im new to the whole world of r/c racers, but as part of my motorsport degree, ive got to build an r/c trike.
not on my own, but as part of a team, and my specific job is engine, clutch and gearbox.
we are allowed to purchase an engine (maximum 2.5cc, or .12 cubic inch), but we have to build our own chassis, suspension, tank, exhaust etc.
unfortunately, any parts we buy in come out of our own pockets, so the budget is pretty tight.
my questions are:
anyone built something like this from scratch, any problems to look out for?
am i better off buying a cheap engine (were looking to spend £60 or less), or getting one second hand off ebay?(i am aware that engines of this type need running in properly before full performance can be achieved) [my thinking is that a second hand one will be run in already, hopefully well, not just razzed from cold]
we were thinking of using a chain and sprockets for the final drive, any experience or advice on this?
any advice is greatly appreciated, thanks.
