slipper mod for bigger engines/might contain traces of brushless
well i went out today and bought what i needed to start testing if my idea of using shim cup springs would work
i was going through the manuals from 3.5 savage to the xl 5.9 and my hunch was confirmed they both use the same slipper pressure spring
no one needs to tell me that the same spring would be ideal for both trucks as there is a huge difference in power
many people just tighten the spring to full lock so it will stop slipping as the settings hpi provides are clearly too soft and the slipper is slipping way too much
by tightening to full lock you are taking away the benefits of the slipper witch is to burn off extreme shock loads under full acceleration as when the truck shifts or lands a jump on throttle
my theory is that now there is a need for a new spring that has about 50-100% more pressure than the stock spring so you can adjust the slipper properly
without yapping on about this any further ill put in some pics
videos will fallow shortly
as i am getting the brushless xl i figured i should figure out a way to save the 3 gear box from exploding as the brushless motor is way to powerful and if i want the gearbox to last
i must be able to adjust the slipper right
soft enough so it will slip when it shifts but still firm enough so it wont keep slipping after the gear has locked in
i was amazed how loose the slipper is when going after hpi instructions
here is the first video (the original slipper spring) it really shows how loose it is at hpi setting

and here is the second video it shows how much firmer the slipper is grabbing but still adjustable
the pressure is now way past the pressure of the original spring without going to full lock
