hi everyone i have the gearbox back it has new metal gears to run along side the plastic casing and nylon motor gear, running the different materials together with lots of grease should cut out most of the friction what causes the gearbox to break, only testing will tell if it don't work then we will try another option,
That sounds similar to Adam Harper's version of a strengthened gearbox, sadly we destroyed one of those when experimenting on Jason Bradbury's maxed out C5.
Here's the link ;
http://c5alive.co.uk/forum/index.php?topic=181.0We were being discreet at the time, so Jason isn't mentioned in the thread. But the pictures are of the remains of two different gearboxes. Look closely at the thread on the inside of the brown casing, it shows where the metal gears have worn it away.
I hate to sound negative, but the conclusion we reached at the time was that the metal & plastic combination wasn't the way forward.
Having said that , it is always worth taking a look at what you have and seeing if it is an improvement on what we tested last year
Plus I am really impressed at what you've managed to achieve in such a really short time
