froggy8 Posted March 15, 2015 Share Posted March 15, 2015 The beauty of brushless motors is they require little maintenance if they don't get submerged in water. Just need to keep an eye on the bearings and try not to overgear and cook it. nice one! right now i am running 20t and stock spur, think its 44t. i want to gear it up to 25t pinion, that still will be fine wont it?

Gearing is dependant on serval things, motor, ESC, LiPo's, terrain, tyre size, driving style etc.... All have to be within limits. Changing gearing is all about trial and hopefully no error. What are your ESC and motor temps like on the current gearing? You really just need to run it and periodically check the temps. Quote Link to comment Share on other sites More sharing options...
froggy8 Posted March 15, 2015 Share Posted March 15, 2015 ok not checked the temps as i thought it was under geared, will check next time i run it Quote Link to comment Share on other sites More sharing options...

froggy8 Posted March 15, 2015 Share Posted March 15, 2015 because someone on here with a 1717 was using 34t so i just assume i was undergeared Quote Link to comment Share on other sites More sharing options...
DannyP Posted March 15, 2015 Share Posted March 15, 2015 because someone on here with a 1717 was using 34t so i just assume i was undergeared 34t pinion? Seriously? In a Savage? What was the spur? You still have the standard centre transmission or Alza CD? 20/44 is stock gearing for a Savage flux I believe. You really need to just trial gearing yourself and keep a close eye on temps.

froggy8 Posted March 15, 2015 Share Posted March 15, 2015 i dont remember what spur he had, he told me he was using it for speed run, yes mine is the standard transmission. so my gearing is stock? no probs, i will check temp as soon as i take it out again, dont think it will be anytime soon as i fancy trying something different Quote Link to comment Share on other sites More sharing options...

Yes I think 20/44 is stock. Quote Link to comment Share on other sites More sharing options...
froggy8 Posted March 15, 2015 Share Posted March 15, 2015 i only go on field and occasionally road, just need to get some road tires as don't want to ruin the ones ive got Quote Link to comment Share on other sites More sharing options...
DannyP Posted March 21, 2015 Share Posted March 21, 2015 Let me know what they say please Shipping is $28 for a Poseidon motor Had my Savage out again today, it's an animal but again the motor slipped. I have been launching it over some big jumps at the BMX track but it's so annoying. I was running for 30minutes and the packs came off with 3.71v left in the cells. Motor slipped before the LVC kicked in so I should get a bit more runtime if i can sort the motor slip. Quote Link to comment Share on other sites More sharing options...

DannyP Posted March 21, 2015 Share Posted March 21, 2015 A hex driver, if I go any tighter the heads will snap off the bolts. I think the problem is I don't have enough thread in the motor and no washers. Think I am using an 8mm bolt but a 10mm bolt is to long without washers. Motor is fine until I start getting big air and the it slides down tightening the mesh. Quote Link to comment Share on other sites More sharing options...

DannyP Posted March 21, 2015 Share Posted March 21, 2015 Yes I am running a CD. Sure 10mm bolts hit something in the motor. Quote Link to comment Share on other sites More sharing options...
Corbs10 Posted March 21, 2015 Share Posted March 21, 2015 Yes I am running a CD. Sure 10mm bolts hit something in the motor. there about 3mm behind the end bell so the thickness of the endbell +1mm should be the right Quote Link to comment Share on other sites More sharing options...
DannyP Posted March 21, 2015 Share Posted March 21, 2015 10mm bolts should be ok with washers. Sure they were only just to long to tighten it up. Quote Link to comment Share on other sites More sharing options...

DannyP Posted March 21, 2015 Share Posted March 21, 2015 I need to find some washers that fit in the slots in the Alza CD or trim some down. Quote Link to comment Share on other sites More sharing options...
Tug Posted March 21, 2015 Share Posted March 21, 2015 I used brass 4mm washers, the softness of the brass allowed me to cut them easily. Quote Link to comment Share on other sites More sharing options...
Wrighty8766 Posted March 21, 2015 Share Posted March 21, 2015 I need to find some washers that fit in the slots in the Alza CD or trim some down. Just order some m4 split washers, they should do it Quote Link to comment Share on other sites More sharing options...
DannyP Posted March 21, 2015 Share Posted March 21, 2015 There isn't much room for washers the have a bigger OD than the head of the bolt, annoying. Quote Link to comment Share on other sites More sharing options...
Wrighty8766 Posted March 21, 2015 Share Posted March 21, 2015 Split washers are usually only slightly bigger then the bolt head, for a quid of two it's worth a try Quote Link to comment Share on other sites More sharing options...
