Final drive gear ratio: 2.125:1 with 16t layshaft. 2:1 with 17t layshaft Chassis length: 331 mm The Lancia and MR2 parts are only the parts needed to fit directly onto this chassis and require the purchase of the respective bodies to complete: -https://cults3d.com/en/3d-model/various/lancia-delta-hf-integrale-evo-1-10-touring-car-body -https://cults3d.com/en/3d-model/various/toyota-mr2-mk2-190mm-rc-car-body Assembly notes: Lubricate the drive cups that the CVD dog bone ends go into and they will last a very long time. If they are not lubricated they will wear instantly -The diffs are strong. They can use 20 mm inner diameterx2mm O-rings to keep the grease in. They are not intended to be filled with silicone fluid. -Removing the support pieces from the diff parts easily: https://youtu.be/vsvI2rdywOM -Do not over tighten any screws. Screws threaded into plastic only need to be snug. Stripped threads can be refreshed with a thin layer of CA glue, or just reprint the parts. That's the cool thing about printed cars. -A PLA motor mounting plate can deform if the motor gets hot. If this is a problem, print the motor plate from PETG, ABS, ASA or nylon, or another more heat resistant material.These materials will shrink more than PLA so take care when pressing in captive nuts, especially with PETG, which will shatter under such tension. Heating the nuts helps. -The middle piece of the motor mount assembly has two small holes for optionally mounting a small 25 mm fan. It will aid with motor cooling by circulating air under the cover and directing it over the motor. Suggested setting. Links measured on outer ends: Front camber links: 38,2 mm Steering links: 40,2 mm Rear camber links: 53,7 mm I suggest starting off with the link in the innermost and uppermost holes. -I suggest starting with the shocks in the center holes on both top and bottom. -The rear belt tensioner pushes up on the belt to tension it. It is accessed by a central screw from the underside of the chassis. -The steering bar has two different mounting positions for the tie rods. The aft position gives more ackerman compensation and the hole in line with the bellcrank bearings has less ackerman compensation. -The slipper clutch and other option parts for the MK Ultra, fit the Veltro as well.
