US Case VAI Tractor
Posted: Fri Dec 17, 2021 11:22 am
Hi There
We don't think we have ever done a 'Show Off' build before on here, but this one is quite special as it has been built for our daughter for here 6th Birthday today
This one has been designed and built to look like a Case VAI tractor from the 1930s and painted in 2 tone civilian colours with red oxide and yellow matt colours
It is fully RC and in 1/16 scale like most of our models are.
It features a 20a esc, a nano servo for steering and a tiny gear reduction 12v motor and runs 2s lipo. THere is a small toolbox the battery hides in, even if the wires for the battery are visible themselves.
From the last tractor we built for our son Oscar, we have gone for a lot slower motor with more torque.
The axle runs as a solid axle and metal bevel gears and mounted on metal ball races as are the front wheels so they run smoothly.
The servo was carefully palced to look like the original steering mechanism of a real version.
Its light weight and runs for 35-40mins on a single charge and is more than capable of running in grass, sand, mud and water(although nothing is waterproof so care needs to be taken)
William designed and made this model and I painted it and weathered lightly
Videos will be posted once we have some
The main chassis and axles and suspension is printed out of PLA, the cosmetic small detail parts are all printed in Water washable Resin on our SLA printer.
The chassis features metal rods inserted to strengthen the main structure.
Some people don't like to hear PLA being used for such an application, but the strength of this little unit is very impressive and our son Oscar has been running his for a while and it gets hard abuse.
We have enough materials to make one more and might go for a blue or a very rusty looking version next, but will add on the extra auxillary drive so we can drive some implements off the back of it
The tyres are printed in TPU by Wayne to our design and offer great grip and have a good level of flexibility for the application.
Abigail was over the moon this morning opening up here new unique model. I wonder what we have to make next year!
