Popular Post MAZ Posted June 11, 2023 Popular Post Share Posted June 11, 2023 Welcome to the start of my Hyper ST Pro kit and brushless build This build is a bit of a nostalgic labour of love 🙂 Nearly all of my RC gear got stolen a few years ago (which included my Hyper ST, KM Baja, Tamiya Blackfoot, and a few other RC's, tools, electrics, etc etc) I wanted to get into the hobby again and really wanted a kit to build. The Hyper ST is an old design now but its a solid platform to work on and the truggy is an absolute tank I'll begin the build tomorrow evening starting with the diffs 🙂 4 Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted June 11, 2023 Share Posted June 11, 2023 Yeh your right the ST's are tanks I have the rtr version converted to electric with some upgrades and it just keeps going awesome trucks Enjoy the build mate 1 Quote Link to comment Share on other sites More sharing options...
MAZ Posted June 13, 2023 Author Share Posted June 13, 2023 @Stormbringer what diff oil weight do you use in your Hyper ST? Quote Link to comment Share on other sites More sharing options...
locky Posted June 13, 2023 Share Posted June 13, 2023 I cant remember exactly what oil wgt I have in mine but it will be in the low 100s for brushless not 10s for centre diff. If you have the spider diff then it is a pain to fill. Quote Link to comment Share on other sites More sharing options...

If you have the spider diff then it is a pain to fill. I'm having a bit of an issue with getting my head around the weight measurements for diff oil. When I was in to RC about 10 years ago the diff oils I bought were measured in 'wt' these days it looks like they're measured in 'cst' (although I do remember seeing some back then in cst as well..) I think my old Hyper ST truggy was running 7k-10k-5k or maybe it was 10k-10k-5k (That was in wt, 7000wt, 10,000wt, 5000wt) Trying to find the equivalent weight in cst is really doing my head in - it also doesn't help that anything number related also really does my head in 🤯🤦🏻♂️🤦🏻♂️ 1 Quote Link to comment Share on other sites More sharing options...
Yrkoon Posted June 13, 2023 Share Posted June 13, 2023 dont know what weight oil is in mine as the guy i got it from serviced the diffs before i got it. Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted June 13, 2023 Share Posted June 13, 2023 Hmmm now your asking i think its 100k centre 15k front and 30k rear or could be 15k rear 30k front but honestly cant remember But im sure i mentioned what it is in my conversion thread 1 Quote Link to comment Share on other sites More sharing options...
locky Posted June 13, 2023 Share Posted June 13, 2023 I generally use Team Associated oil, so 250k cst in middle and 30k/20k cst in f/r. Mine probably need a service and top up as just ran them for first time this year and one sounds noisy. It comes down to preference and whether you can feel an actual difference when changing oil wgt. Thicker wgt in centre diff helps reduce front wheel ballooning.

MAZ Posted June 14, 2023 Author Share Posted June 14, 2023 Bought a few essentials today to go towards the build. I'm pretty busy this evening so I won't get the chance to start building the ST but I will be starting it soon... ...Hopefully 🙄🙄 1 Quote Link to comment Share on other sites More sharing options...

Its been sometime since serviced the diffs so just going on memory and the bottles of oil I have left. You can always dilute a too thick oil with a thinner one, so the range of oils you have should be ok. What motor and esc will you be using?

I think anywhere between a 2000kv to a 2250kv motor, matched with an appropriate esc I open to all suggestions though as I'm having to relearn everything rc Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted June 14, 2023 Share Posted June 14, 2023 (edited) Im using this in my st with a 16 tooth pinion and feel i could go up a tooth or 2 as esc and motor run coolish https://www.modelsport.co.uk/product/hobbywing-cml-ezrun-max8-with-2200kv-motor-combo-397267 Im running it on 4s Edited June 14, 2023 by Stormbringer Quote Link to comment Share on other sites More sharing options...

Does it matter if there are tiny air bubbles in the oil? Can't remember if its best to leave them to slowly work their way or not? 1 Quote Link to comment Share on other sites More sharing options...
