Kyosho chain adapted sprockets designed , printed and tested , its a complete car !


I had a spare Kyosho chain so this was inevitable , fits well even through the chain guide , I've not checked if the chain guard on the side of the gearbox fits but it won't take much to adapt it .

I had some minor teething trouble with the gearbox design yesterday but its been simply rectified , I have a new version of the body printing as well .
I'm hoping to get some video later but its a typical British summer day , light drizzle and overcast ....

I finally got some video footage , also had my first part failure , both front suspension top arms cracked at the inner rear mounting , those parts are some of the last parts on the car that are still made of PETG , its flexible but can crack or shatter on impact , not sure weather to print a new set in ABS or Nylon .I also drew up and printed a wing and wing mounts in TPU .

First reinforced top arm , I've made it so i no longer need a nut but the crew taps into the rear pivot , its made of nylon as well so much more impact resistant .

Awesome work mate !


as i am planning on a retro online museum for many older iconic cars and wanted to include a lot of self created (and tested in Model and used in driving) 3D parts i want to ask you whether it is possible to get some CAD Data from you to add it to the rest of the lineup. STEP format would be preferred as my solidworks machine easily accepts that format - IGES would be ideal too - beneath SLDPRT Data (wich is native solidworks data) of course .


All other data like STP, 3DS a.s.o. do not really allow changes - and some small changes here and there are quite helpful - especially as my own 834 B might need some part from time to time.



Any chance you might share the CAD Data set with all of us ?

At some point in the near future it should be on Shapeways , I'm not releasing the files into the wild at the moment ,sorry but it represents quite a chunk of work .

Fully Nylon front suspension and TPU body , the PLA body started cracking and it rattled something awful so made the new one in TPU a flexible plastic , sorry about the colour its all i had .

Oops , looks like another part needs the nylon treatment , this broke landing a jump Next month I'll get some carbon fill nylon , its easier to print as it warps less , its more rigid and its black so its going to look right as well.

Just free hand , I've never seen in the flesh the real parts and i adapted it a bit , the trailing arms to mach are on their way.



it surprising how much it reduces play in the rear arms , i used a nut and bolt through the arms and bearings not just a rod and having slight tension through the axis takes away all the wobble .
If anybody has the real Delta Desert conversion and could give me three measurements i could make it closer to original shape .
1 the overall height from the chassis to the top of the shock mounting beam
2 the height from the chassis to the top of the trailing arm pivot housings
3 the width of the top shock mounting beam at its widest point where the shocks mount
I'd be very grateful and you should be able to measure these points without taking anything apart .

The first few carbon fiber fill nylon parts are rolling off , the first prints were not so good as even out of the sealed bag brand new the filament was damp and needed drying , after drying the results are stunning .
these front arms were printed before i dried the filament and needed a lot of clean up .


this rear arm is after drying and as it came off the print bed with no clean up , its stunning !

I went back to the plain nylon c hubs and i think that's working better . I got dogged off with the constant failure of the one way roller bearings in the front drive hubs so i drew up and printed some direct drive ones instead .


Also printed up a CF nylon front bulkhead , shown next to the plain nylon one .


Had a couple more runs today and the gears are still going strong , should have time for another run later .
Its quite a learning curve working out what material to use where , the C hubs and chain sprockets are better in the plain nylon , suspension arms ,gears and gearbox in CF nylon , top deck / chain guide ,battery tray and wheels are all fine in ABS and just the rear chain guide in PLA .
These are my experiences anyway but it adds to the complexity when selling parts , if its a car that's going to get used a little , raced or displayed you might want different quality parts .... more to think about .
