So this is the end of this saga to build your own rc car, the #5th chapter!!! The suspension. In spanish we say "suspense" and that's why i let it for the end...
But also because is now when more decisive your selection is. You have to select the right CVD to acomplish the kind of car you want. Shorter ones will be needed to build On road cars or scale cars, and bigger ones to build a buggy, truggy or short course car.
I have seen unbelieveable prices for HSP CVDs coming from china but also i think they are some of the most extended and the references are clear.
I have spent some time researching about CVDs and i have seen there are at least 3 types.
TYPEA Steering Blocks are designed for Vandal CVDs. They use two 5x10x4 bearings each.
TYPEB Steering Blocks are for HSP 122015, HSP 166015 and HSP 188015. They use one 5x10x4 bearing and other 10x15x4 bearing each.
TYPEC Steering Blocks are like B but the bearings have a little different possition. They would be HSP 102015, HSP 106015 and HSP 108015
TYPED Steering Blocks are for Reely CVDs, the ones used in OpenRC Truggy.
I think the rear adjustable steering blocks needs to be improved and i have removed them. As a quick alternative i made fixed rear C-hubs for the A, B, C and D types, but also for rear Vandal Dogbones and wheel-vases.
As you can see in the drawings, i have made the arms for at least 3 kind of CVD length. You can use the short one, MRCC_SUS_LA475 to build an onroad or scale car and MRCC_SUS_LA715 or MRCC_SUS_LA769 to build an off-road car. This last Lower Arm has been added to be used with 188015 and 108015 CVDs, in combination with typeB or typeC Hubs.
NEW: Improved LA715 and LA769 lower arms, with pin lock system and little reinforced. Look for the "upgraded" version of the LA's
So that's it! Print a C-hubs pair, then print two front steering blocks of the correct type for your CVDs and a Rear fixed Chubs pair.
As Yuran suggested, maybe some of you don't want the Adjustable Length Upper Arms and want some fixed length ones instead. I have created 5 Upper Arms for each of the lower arms. So if you want 0 Camber, you should use the MRCC_SUS_UAXXX with same numeration as the lower arm. Those would be UA475, UA715 and UA769. The variations created from this numbers are 0,5 and 1mm shorter and longer.
I'll post the rest of the info to build a whole car in the related MyRCCar Group. Please join us or make your questions there if they are not directly related to this thing
