I thought now would be a good time to resurrect and old friend of mine.
I built this chassis setup a few years ago with the intention on installing the HPI gas engine that has not been released yet (if ever).
I ran it initially to test it out with a XTM 457 for about ½ gallon and then disassembled it, polished the parts and boxed it up while waiting for the engine to be released.
Well I have gotten tired of waiting and decided to put it back together and run it with a Fresh Rossi .28 and 1 of Robin’s pipes I snatched from my twin engine build.
I changed a few things up during assembly and thought I would do a write up and list all the things I have made/done to it up to this point.
All aluminum is either T6 7075 or T6 6061.
Main chassis:
5 pieces, main center plate with 4 plates attached at each corner for servo and fuel tank mounting. Chassis extended front and rear with a 15.5 inch wheel base.
6061 New Era 4 point chassis braces.
GA 7075 bulkheads.
Custom bulkhead braces.
Custom shock towers and rear wing mount.
Custom skid plates and wear cover plates.
Custom rear skid lower braces.
Suspension:
UE wide track arms.
Custom length hinge pins with capture system integrated into main chassis, skids and bulkheads.
Ofna LX One rear shocks all around with Revo VD pistons, custom springs and internal/external limiters.
Tekno axle carriers.
Steering bell crank is modified from an Ofna LX One.
Drive train:
Custom 3 shoe engine clutch. (Top secret stuff)
Torque control slipper clutch with custom 7075 slipper disk.
Custom single speed transmission with a 2:1 output ratio (internal ratio can be changed to suite my needs depending on track, also have the option for an internal 1/8th scale center differential and rear brake setup).
Modified UE drive cups, 6mm tranny/8mm diffs.
HPI Dog bone center shafts.
Modified HPI savage differential housings sandwiched between the bulkheads with savage flux BP diffs.
UE drive cups with shaft for flux diff outputs.
UE dog bones for wheel shafts.
UE 8mm drive cups mounted on custom 8mm stub axles.
Ofna 17mm wheel hexes.
Its geared 18cb/38sg and should top out @ about 40mph, but it should get there quick with a good bottom end to pull out of the corners and to clear the bigger jumps.
Weight: 11lbs 3oz without lid or fuel.
I need a couple bearings for the front diff before I can finish the front diff and wheel shafts, some new toe links and a lid before I can put it to the test.
Going to order some PL Bad Lands for the loose stuff at the track also, the Hole Shots on it just don’t have much grip on the loose/dusty clay.
I’m sure I’m forgetting some stuff but here are some pics as it sits.
Anyone have any ideas on a Body for a 15 ½ inch wheel base?
