MN Model MN128 with SCX10 Shocks

This time I replace the upgrade shocks with new upgraded shocks.

Bill mount them upside down thanks great video

[@BillsWorkbench]

I think you are referring to the old shocks. If so, they leaked so badly that, when upside down, the shocks did not have any damping at the first part of travel.

Use surpass 540 motor crawler for better performance

[@BillsWorkbench]

I was thinking of doing that, but I want to go brushless. I have a new outboard brushless motor to try, but I need to use the lathe to make the shaft fit the pinion. Stay tuned.

@@BillsWorkbench thats better. Using blhelli esc and outrunner motor. 2700kv are enough

[@BillsWorkbench]

@@febryant9720 It's a C2836 1120KV motor. I wanted something a bit less KV, as it's a crawler. We shall see how that goes.

[@febryant9720]

@@BillsWorkbench good but. Too slow I use the outrunner 2217 2700kv, best speed and much torque

Would you please make tutorial how to make mn128 V2 waterproof.😊

[@BillsWorkbench]

I don't have my MN-128 stock enough to do that. But maybe I can do that with my MN-82. The Electronics would be straight forward, but the servo would require a replacement after a while of using in water. To water proof the Electronics I would use Silicone Conformal Coating and apply that to both sides of the Receiver and the board inside the servo. The battery connection would also be an issue, I would use electrical tape on that to keep the water out. One issue I can see is the speed controller part of the receiver board overheating after applying the Silicone Conformal Coating. Regarding the gears you would need to apply grease to keep the water out. After using it in water you would need to properly clean out the axels and transmission. You would also need to re-grease and oil all the proper parts. It's a lot of work to keep a RC crawler working well, I am lazy when it comes to that. Maybe that I why I don't use my crawlers in water.

Are the additional springs less thick or are they the same ?

[@BillsWorkbench]

The additional springs have a different spring rate, I don't not remember if they were harder or softer. But I did end up experimenting with the different rates to find a good balance with the battery I am using. The battery I am using is heavier than the stock, so that will play into the tuning as well. Overall I am happy with the 70mm shocks. It's much better than stock and better than the cheap leaky ones.

[@yaucisn]

@@BillsWorkbench I see that even though they are oil shock absorbers, I see them as somewhat hard, and I think it is because of the springs, which is why I wanted to know if the other additional springs were softer to mount those on them.

[@BillsWorkbench]

@@yaucisn I understand your question. I really don't remember if I put on the stiff or soft or a mixture. All I can offer is that I am happy with 20wt oil in them and one of the sets of springs that came with the kit.

[@yaucisn]

Size shocks ?

[@BillsWorkbench]

Here are the shocks I used. 70mm Injora RC Shocks: amzn.to/3TorJuQ I just got back from running it on a trail ride and they work great. No more bouncing.

[@yaucisn]

And density oil ?@@BillsWorkbench

[@BillsWorkbench]

@@yaucisn I went with 20.

[@vlozity]

Use proper spacers, not those screw nuts. Sorry to say this, your not showing how to properly build shocks and I am not sure why your even showing the wrong way of doing things... that's a bad hack job.

[@BillsWorkbench]

First of all thank you for watching and taking the time to leave a comment. Yes I did slip shot, job installing the shocks. I owe everyone a video creating new, adjustable, shock mounts and as always I will share the 3d models so anyone can print their own.
