A quick cure for too much steering. Put glue on the front tires edges.

Good to hear the car is better...I knew 100k in the rear was too much....

What hole piston are you running with the 1000 cst? With the RCM shocks, I run 600 cst both front and rear with a 1 hole front and 2 hole rear piston.

Pass you soon...

The serpent site tells you to make the holes slightly larger by drilling them and how to perform the mod which is easy, I've only had one leaky one which was the 1st rushed assembly & IMO due to how i assembled it, currently I've got 4 diffs for my 747 ready to go, the two in the car are standard 4 gear and the other 2 are set up with 2 gears, all of them are standard unmodified housings and haven't had so much of a hint of leak/s.. I think a fair bit depends on how it's put together or maybe I'm just lucky, I haven't had to do the tip suggested by serpent "incase" it happens, def dosnt happen to all I know that for sure..
Ive got about 7-8 diffs all up so ill drill a spare out and see what results it gives, or if the assembly is a little less easier on tolerences all round, but so far I've been lucky..

I borrowed a 1600 mAh Life from a friend to test it. This had a size of 85x30x17mm and i also was very thight and ther is even an extra balancing plug to fit. This life wasn't much smaller than the NiMh.

What battery do you use for a S747?
Was using the same, 5cell NiMH pack but mine was in decent clearence of the side belt/tank, I'm currenty running a LiFe atm, which was almost the same depth/fit, a little more narrower giving even more clearence to the belt etc
This is what I'm running below.. I've also got a exceed lipo but prefer not to use lipos due to volt reg etc..

Yeah I drilled out the holes to the rear diff to use bigger screws, I'm good now! I think the small screws with the Phillips head just didn't get tight enough......(didnt help that I stripped one also). And i also changed the O ring to a orange one I got from my buddy, no leaks ever since......

The front I think the oil is just to thick to leake out! 300k

Default 747 options!!

Fellas quick question, Have any of you played around with cutting out the hexagon shapes on the front lower bumper? (I see its done on Dominics 747) Also regarding springs, Can u run short fronts n long rear? Or should you not mix front to back? Do long springs offer a different feel than short? Should I not use short at all?

Thanks

I've cut one of my spare bumpers far hex edges out, haven't tried it yet unfort with rain when ive got abit of time, i will in the next week, it's meant to be a noticeable change,
also the the 25G chassis weight slide makes a HUGE diff if you haven't tried or have it yet, slide it right back and it gives a ton of steering "even tho there is plenty without it" but at expenses of heavier rear tyre wear, slide front gives less steering and more front tyre wear, good to play around and good if your running mixed tyre to find that sweet spot or balance.. It's been interesting to see the diff it makes..
Re the springs, i've got the SS shock set and low towers and standard set, I've never mixed springs though, I've just started running the 2013 super short shock set and low towers with good results..

I always run my bumper with the outer hexes removed. I feel it gives better initial turn in. I've tried running long springs in the rear. The only problem is you will run out of adjustment on the collar if you run tall tires. The long springs are just a tad too long.

Pass you soon...

Thanks, but my car came with long springs! So u prefer short only for that reason? No handling differences?

I never tried them because I could not set my ride height. I ran them on my 733 but the 747 has different rear geometry.... Way go team Serpent @ the ENS in Austria. Good job!!!!

Never had much success with the holes cut in the bumper but is on my list of things to test again.

We run the long springs with the shock extentions and have had great success
