What kind of battery options are there? Are we stuck with the Dynamite 650 and 800 ones? Can't see to find any other that might fit.

Iíve got some Tattu 3S750mah packs on the way since I prefer a lower kv motor on more voltage, and they are 95C so should have low IR.

Hi all,
My first Losi was a Mini T back 16 years ago, could not resist to the new release, then 1 Mini T & 1 Mini B in 2 weeks

Some questions I need answers to:
1/ Is the Mini T ball diff a drop in replacement for the original gear diff?
2/ Is there any lower cost alternative to the original tires. I run on asphalt mainly, and stock carpet tires are already out after 120 min of uses

I have a rig I can use to test/measure the spring rate for shock springs. It is a bit crude, but it works well enough for my needs. I tested the 1st gen springs and the new 2.0 generation springs - here are my results (values are in lbs/in):
Code:
Testing Shock Springs - Summary                    
Front:            Rear:        
    Pink    0.79        Silver 2.0  0.70
    Silver    0.82        Silver 1.0  0.83
    Black    1.26        Black        1.32
    Red    1.28        Green        1.55
    Orange    1.91        Blue        1.71
    Copper    2.13        Copper        2.02

Nice, I'm going to assume that the reason why the newer springs are stiffer is due to the 2.0 being a little heavier than the 1.0. Do the old springs fit on the new shock bodies? Are the new springs you tested the springs for the B or T? The B springs are shorter than the T's, so spring rates may be different.

When we raced the 1.0 T we used AE 18T springs, they seemed to work better than the Losi springs.

The Gen 1 springs I tested were new old stock - the new springs were technically for the "T" 2.0 since I was trying to compare apples to apples. The Gen 1 springs are about .2" longer than the 2.0 springs. Other than the small difference in length, the springs all seem interchangable, and it is interesting that the "soft", "medium", and "firm" springs seem very close from 1.0 to 2.0 rates.

There is, of necessity, some variance in the ratings since my rig requires me to measure everything manually - I measure the unloaded length of each spring, then I put around 12 oz of weight on it and I measure again. The difference in length for the known weight allows me to then calc the spring rate, but as I said it is all manually measured...

Awesome, great info, thank you.

For those of you that are having trouble with the stock servo, you may be able to fix it yourself. I have had my servo go dead and get stuck a few times and have been able to bring it back to life. Remove the servo from the chassis, remove the 4 screws on the bottom of the servo, carefully pull apart, and realign the gears, you should be able to do this by pressing down on them, reassemble. This has worked every time for me so far.

I think I may have been given bad info regarding the re-release of the MIP diff and my diff case is leaking grease, I'm down to a 15t pinion and my motor is still running hot, so I need to rebuild sooner than later. Does anyone know of any grease that is heavier than AE black grease, I've seen Bad Horsie's, but it may be a little too thick.
