Thanks for the Wow’s… And Rolex, I’m out of wax :0
Greywolf, My wife calls it my Art work and wonders how I manage to keep it so shiny when my hands are so dirty:lol:
A couple of Savox 1256 servos installed for steering and throttle/brake duties.
Throttle linkage: It was problematic from the start of this build. I tried to set it up with available off the shelf parts but after several attempts I had to make a custom bellcrank with the dimensions to fit the space available and correct length and angles of the arms.
I cut this out of a hunk of T6 and machined it to accept 2 flanged bearings. The little stubby post mounts on the front center upper chassis brace and bearings fit the post.
A threaded rod with thumb adjuster makes the connection from servo horn to one arm of the bellcrank. The connection from the other arm to the throttle valve(s) installs later.
The time I spent making that little bellcrank was well worth the effort. The throttle works perfectly now with no binding and a solid return to the idle position on both engines.
Receiver box is a modified old school TMaxx box that’s been cut down (shorter with an off/on switch add to the area where the rubber plug fits.
It mounts directly on top of the front chassis brace with a couple plates for quick & easy access.
I use the Traxxas TQI system with docking base and my Iphone. I know a lot of people don’t like the tqi but I haven’t had any issues out of mine and it has great range compared to others I’ve tested. The traxxas link app makes it easy for me to set everything up or make little changes. I may also invest in the GPS they finally have available.
I will say that without the docking system I wouldn’t use the TQI. It’s just too complicated without the app.
Transmission: This one is a custom 2 speed with the lowest ratio possible within the confined space of the housing. There just isn’t any more room to install larger gears.
My theoretical calculations put the rig at 121mph top speed. Comparing that to what I know it has done in the past with other gearing I should get close to a 113mph if all goes well. The rear center driveshaft is the
HPI savage wheel shaft I mentioned earlier in the thread.
The brake is a custom setup with a steel rotor and replaceable pads mounted to aluminum calipers I made. The spurs gears mount directly on the input shaft without a slipper clutch.
.
Chassis side plates: 1.5mm thick T6. These just bolt to the edge of the main chassis deck to make up the final outline. The cutouts are to shed a little weight, let air in/out and look cool
Mounted to chassis.
Power plants: Novarossi .28’s with Nova headers. I’m trying a different clutch setup this go round with composite shoes (3) installed in the leading edge configuration. I ran Buku komposite clutches prior to this but have worn out 6 sets of shoes with the tall gears.
Pipes are ERCM end bleeds that Robin made for me with custom bent stingers. I have now cut the stingers off (sorry bud) and will be adding some with a different bend and slightly longer to fit through the body better.
I also de-anodized the top/bottom and outer edges of the cooling fins on the Nova heads for a little more bling. With a little push I may polish the entire cooling heads on a rainy day.
Extensions for the ERCM pipes. These are just bent out of plated copper to get the right angle/bend for now. I have to order some stainless tubing and black silicon sleeve to make the connection.
I got more done than I thought I would today, must have been that extra pot o coffee.
