So since HPI ESC and Flux motors are rebranded Castle Creation at least for the 1/8 lineup. I decided to grab an HPI Vorza ESC, Torx 2200 KV motor, and a 6s 40x 4300 mAh SPC battery Removing the old ESC was probably the hardest part (you have to unscrew the ESC, unscrew the ESC mounting plate, untangle the wires to the receiver and disconnect the wires). Motor came off super easy. knowing how the ESC came off it was rather easy to attach the new one. no screw holes on the new one to mount so out came the heavy duty velcro so i can remove things with ease later if i choose. re run the wires, connect the esc fan and bam ESC is good to go. Removing the motor was a snap, 5 screws on the bottom of the chassis then the two that mount the motor itself to the transmission, remove the pinion gear and we are good to go. Mounting the new one required smaller screws but they still fit the mount. After grinding the motor heat sinks down a little bit i managed to get everything to fit rather nice. the heat sinks just barely rest on the chassis now so i guess a plus side is i get some extra cooling on the bottom of the motor in some weird thermodynamic way if it really helps that much. Re-configure the battery tray for a single 6S battery and bam time to program the ESC.... crap I had closed up the receiver already, unseal the receiver plug in the ESC configure with castles "castle link system" re-attach and close everything up. power up, configure ESC with the Transmitter for throttle range. ok we're good......... until you tap the gas and the car goes in reverse. Should be an easy fix so i swapped two cables for the motor and esc and try to re-configure. doesn't work right. Hop into the Castle link again change the configuration for what way the motor is running as "Forward" plug everything back together again. Reconfigure the Transmitter and ESC. BAM everything works great well minus me dropping the Transmitter and the car flying across the room. Anyways now that all that is done. I took the car out today and ran it. MAN the thing feels like a whole new beast. it ran awesome i couldn't believe the difference. I highly recommend 6s on the Arrma Talion. you can pull wheelies on demand at low speeds but with a little throttle control its an amazing RC. I'm going to grab a wheelie bar next just so when i do pull a wheelie i don't need to worry about flipping the thing over backwards. I'm also thinking of lower the pinion gear down a level as well because it has a ton of speed and for where i drive i can probably do without as high of a top end but we'll see. I'll Post a couple pictures later of everything in place.
