Well a bit more running and ended up letting the magic smoke out of one of the emax servos, a bit concerning but the first one i got has been great so far so idk. decided to treat this project a bit and got a Drift Art DVF-AFRC V3 servo (read quite a few really good reviews on them, and they were on sale), so going to be installing that when it comes in. which did lead me to notice an error in my design. More on that below.
Of course! As soon as i call it done, ended up finding some improvements, and found an error i made in design.
First Improvement:
Originally i had this car designed with what i had on hand, which was a WL toys chassis. overall all fine and well, but one area that i should have looked deeper was the hub bearings, which are 3x7x2mm, these are quite expensive for what they are ($15 for x8), and i had only done a little research into what else was available and had only come up with 3x6x2.5mm which i did end up using for the transmission case. now these wouldn't work as the axle stub is 5mm and would have nothing to seat against. come to find out if i would have scrolled like 3 listings further down, from where i had stopped, 3x6x2mm bearings exist and and at a much more reasonable cost ($8 for x10), and 10 happens to be exactly how many i need to use in the transmission, and for all 4 wheels, cutting $14 from required parts and less items to order.
no exciting pictures for this, just made the hubs 1mm smaller diameter
Second Improvement:
Next the top RX tray, with how tall the JR connectors stick up, the wires out of the back of the connectors were hitting the inside of the body a bit. Revised the connection to the servo sliders to sit 2mm lower. how i revised this also allows for more length adjustment as well, but in the future can be slightly more revised for the sliders to be 1.5mm 2mm thick plates when i get to that point.
Error:
again following with the theme of the first improvement, i was designing with what i had, which included a Emax ES08MA-II, and ECOPower 827 servo, decent budget servos except for the one), and i want to retain the ability for them to be used, but most mini drift servos's cases are about 4mm shorter, so the back slider part of the servo sliders need to be extended 4mm.
i think for manual purposes, I'm just going to have an "amended" section, so i don't have to go through and completely rebuild again at least for now.
hoping to have the servo in about a week to run it again
