norcoforever Posted October 23, 2014 Share Posted October 23, 2014 Are the leopard 4074 motors and 4274 motors the same just that the 4274 has the heat sink? Quote Link to comment Share on other sites More sharing options...
Dubberz Posted October 23, 2014 Share Posted October 23, 2014 40mm diameter and 42 diameter can mate Quote Link to comment Share on other sites More sharing options...
norcoforever Posted October 23, 2014 Author Share Posted October 23, 2014 40mm diameter and 42 diameter can mate I know that lol but is the 42mm due to the heat sink round it or is the motor actually 42mm with the heat sink on top meaning it won't fit my tekno mount Quote Link to comment Share on other sites More sharing options...
capri-boy Posted October 23, 2014 Share Posted October 23, 2014 I thought I'd read it's just the finned version, but yh the 42 should be 42mm in diameter inc the fins. Quote Link to comment Share on other sites More sharing options...
mydoddy69 Posted October 23, 2014 Share Posted October 23, 2014 There both a 40mm can its just a 1mm heatsink added which makes it 42mm if you catch my drift Quote Link to comment Share on other sites More sharing options...
Tug Posted October 23, 2014 Share Posted October 23, 2014 What doddy said. The heatsink really helps shift the heat too! Quote Link to comment Share on other sites More sharing options...
norcoforever Posted October 23, 2014 Author Share Posted October 23, 2014 What doddy said. The heatsink really helps shift the heat too! after a bit of research I've actually gone for a 2000kv 4082 should have plenty of grunt on 5s. The tekin just wasn't happy when I was doing speed tests tried pinions ranging from 15 to 20 and couldn't get it to stay below 60 degrees after 10 or so minutes Quote Link to comment Share on other sites More sharing options...

Found for me it was too much as it would punch out so much power it would round the hex in the wheel too often on the mt4.. To be honest i never found a huge improvement on temps some yes, but there is a huge torque improvement !! Quote Link to comment Share on other sites More sharing options...

turtletom100 Posted October 25, 2014 Share Posted October 25, 2014 (edited) I thought brushless motors were fine with out heatsink or fans. I switched my brushed motor that had a heatsink on for a brushless leopard and never put the heatsink back on. Reading this maybe I should. I got 2 so might try and put both on to help temps.
