Hey all,
I've decided to rebuild my first build, the Norco Empire 5 bike that once had a planetary gearbox and Astroflight 8150. The Astro has since found a new home in the UK and the crappy cheap-ass planetary gearbox went in the rubbish bin ages ago. Up 'till now i'd planned on transferring the Cyclone driveline thats in my Specialized FSR into this bike but i've since had a change of plans...
I've had a hankering to do another RC drive so when i stumbled across those 130kv 80-100 outrunners on ebay for $160AUD (shipped) that are similar if not the same as the well known Turnigy 80-100's, i thought what the hell, why not!
I'll be pairing this up with a spare old Castle Creations HV140 and cutdown Magura throttle from the Astro build though this time i won't be using a Throttlizer, i'll instead go for one of Justin's brilliant little RC CA interface thingys to make it all come together and current limit it to around 100 - 110amps.
If the HV140 dies eventually, i'll see if Castle can send me out a Rev2 HV160 8)
The frame will also go under the knife yet again, this time 'round using much thinner 3mm aluminium instead of the original's 5 and 10mm which i've since found to be way overkill and too heavy. Once again the motor will be in the frame but i've come up with a neat way to duct airflow around the motor and exiting behind the motor / frame while not seeing the motor from the side. More on this later...
Gear reduction wise it'll comprise a 2 stage #25 drive to the cranks with the exact gear ratios yet to be decided as i'm not sure yet whether to gear it low for extreme climbing or a little higher for around 75-80kph top speed.
The bike already has an adjustable Marzocchi TST airsprung rear shock and this will work along side my RockShox 454 Pike 20mm axle airsprung fork.
Rear end uses a 12mm Rockshox Maxle QR which sould be quite stiff and helpfull in controlling rear-end flex.
Travel is 5.5" front and 5" rear. Wheelbase will be lengthened to around 1190mm.
Weight wise this bike will come in well below my Intense M3 / Clyt HT3525 build, around or just under 30kg should be a given depending on whether i settle on a 15 or 20ah lipo setup.
Once again this build won't really start untill i've finished a fellow member's frame mods i've been stuffing around with for ages so there won't be many updates for a while except if some parts come in. The motor is already ordered but i'm yet to order the RC CA from Justin (if he has any in stock that is).
