novamadcars Posted February 14, 2020 Share Posted February 14, 2020 Today I’ve moved all the electrics over to the alloy radio plate. And assembled a little more of the front end 1 Quote Link to comment Share on other sites More sharing options...
nut-nut Posted February 14, 2020 Share Posted February 14, 2020 replaced a plug on an old ESC and motor combo for testing for a setup for my daughter, who has unexpectedly become interested in RC. Got it working, all is looking good, just need the roller now. Hopefully going to secure one of a nice guy here, let's see if she likes it. 1 Quote Link to comment Share on other sites More sharing options...

MacRaguel Posted February 15, 2020 Share Posted February 15, 2020 A New radio for the kyosho and my slowly growing collection of cars Flysky Noble NB4 absolutely loving this thing so far, build quality, accessibility, being able to throw it lefty, built in emulator so I’ve tried it out on VRC, get some finger training in it feels fantastic in the hand and everything feels just right ergonomically, I’m most impressed had one issue in setting up what with all the updates to the firmware and to the rx but ironed that out with a quick forum search still trying to get my hands on a couple of V2 receivers for back ups 1 Quote Link to comment Share on other sites More sharing options...
Hell horn. Posted February 15, 2020 Share Posted February 15, 2020 Not today. Late last night. Modded my team associated reflex to run a more interesting body. Cut back of body out. And made a plate for the bed. Going to spray the body too. Looking more fun now. Next job is different wheels for it. Something slightly bigger.

Popular Post MacRaguel Posted February 15, 2020 Popular Post Share Posted February 15, 2020 (edited) Oh, want to add about lanyards now I’ve got a decent radio I felt I needed to get it secure fast after watching lots of what goes on and going to a few races I just couldn’t get behind the traditional lanyard or even some of the high end RC lanyards didn’t hold them secure enough to the body, swinging from the neck, didnt look that strong...not that a radios particularly heavy but still, I want confidence in it so I’ve used a single point rifle harness I had, strong, secure and designed for similar use you can pick them up relatively cheaply.....and you don’t look so train spotterish lol i wear mine close to body but naturally they can be lengthened Edited February 15, 2020 by MacRaguel 4 Quote Link to comment Share on other sites More sharing options...

What's the car and what paint are you using? HPI rs4 3 nitro and I will be using high temp spray. Only as I have some left after spraying some of my 1.1 VR6 engine parts.

zlab Posted February 16, 2020 Share Posted February 16, 2020 adjusted the diffs to run straight. Now they are bellow 0,05mm. It should be good enough 😀 Quote Link to comment Share on other sites More sharing options...

It should be good enough [emoji3]Care to give a very brief explanation of the process here, are you just using pressure to straighten things up or is here more going on?Really wish I had got into precision machining and engineering when I was younger.

zlab Posted February 16, 2020 Share Posted February 16, 2020 @Paul Busby Honestly, no precision machining involved here. Factory diff casings are moulded quite out of tolerance, when i measured factory assebmled diff, the runout was more than 0.3mm! I measure it and mark the spot where the high spot is. Then i just carefully remove some material with fine sandpaper and measure it again when assemled. Fine tuning with tigtening the screws to get it straight as possible.

I went to school for an electronic engineer, but because of the nature of the work i had to get a lot of mechanical knowledge. In the era of the internet it is relatively easy to learn the theory, then it's just practice. On first steps you make a few expensive misstakes and that is how you learn 😁You learn how to rebuild the CNC mill spindle after you destroyed a set of 4 precision bearings, 300€ each 😂 About the diff, here you can see the front one, which still needs a bit of love with the sandpaper 1 Quote Link to comment Share on other sites More sharing options...

I'd say a few big jumps and the bearings would be as round as a marshmallow 😂😂😂 Quote Link to comment Share on other sites More sharing options...
zlab Posted February 16, 2020 Share Posted February 16, 2020 (edited) @Alex97 well the bearings tolerance don't affect much here. The problem is the plastic diff casing which causes runout of the gear. Then you have problems when adjusting the gear mesh. Just right on one spot and then to tight when you rotate it for 180° But if we talk about bearings in RC, i can see that they are all crap. All are made out of chinesium and in bad tolerances 😐 Edited February 16, 2020 by zlab Quote Link to comment Share on other sites More sharing options...
No brains Posted February 16, 2020 Share Posted February 16, 2020 Did some more building on my rock rey kit, made some nice progress, the only thing left to do is build the shocks and paint the body and install the servo and do some little things. But for now I have to wait for my alloy servo horn to arrive, then I can complete it. 3 Quote Link to comment Share on other sites More sharing options...

Pistonhead Posted February 18, 2020 Share Posted February 18, 2020 Ordered some more runtime ahead of a crawler meet at the Cheeswring on Bodmin moor on Sunday, should keep me going along with the other 9400mah between the other three LiPos - two 2200mah 3s and a 5000mah 2s. https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F153739691809 Quote Link to comment Share on other sites More sharing options...

Popular Post everclear1984 Posted February 21, 2020 Popular Post Share Posted February 21, 2020 Built and test fitted the Alza centre diff. What a piece of kit! So simple but so effective Think I need a beefier rear dogbone to match the front 4 Quote Link to comment Share on other sites More sharing options...
Oh How Original Posted February 21, 2020 Share Posted February 21, 2020 Finally got around to giving the Yeti some love after needing it since last September during a particularly hard bashing session, the front is basically shot, internally at least. Ordered what I thought was enough bits, built it back up and realised something else is bent, boo! More waiting on parts 1 Quote Link to comment Share on other sites More sharing options...
