hi all... i have been well busy in the workshop making stainless steel spool holders for a fishing line company so my project has been on the shelve too long, anyway my last post was alloy gear cogs for the box on my 3906 e maxx. well alloy is not the way to go...

as you can see the power of the mm combo has just pushed the alloy away and failed (shame tho as the acceleration was insane). so after a conversation with an old school engineer who had dealings with gear cogs suggested i use ertalon 30gf (has 30% glassfibre and has better strength and heat figures than nylon 6),

oh dear, they lasted a few seconds about twice as long as original cogs.
so now after days in the workshop making cogs that where useless now i have made some that are usefull ....


these cogs are made from a hard grade steel and i finnished them today so now going to put my e maxx back together and sqeeze that trigger
i will post and let yall know how it went...
sorry about naff phone pics but my digital camera is not allowed in the workshop
