when i get micro controllers sorted out , theses esc's could be as cheap as 20 quid !! As for the hdpe , i built my latest FW ( making its first appearance on sunday !) almost entirely out of craigs of cuts from saint ( thanks for those craig ). and when i have bought hdpe in the past , for a FW its only been about 25 quid , and the planet 5 2.4 ghz systems are only 35 quid ( no pound sign on my crappy keyboard)
