Yeah I'm running a mmp, 1410 and 3s in my hyper and it balloons my tires really bad. I'm running 5/10/10 right now, but gonna change the center to 15 cuz its really bad. It was really hard to control on the track down the straight and even jumping it cuz the tires turned into pizza cutters

How did you find the stock diffs? Are they fluid or grease filled?

I bought mine second hand and the guy had already changed the fluids, but I did it again just to be sure. 10k in the center is still too thin

NM, read the manual.
1/5/1. No wonder it balloons so bad.

Well i had a chance to swap the center fluid over to losi 15k this morning, Still balloons pretty aggressively, but he fluid did help a bit.
I went in this morning and changed punch control and lowered the timing a little bit to see if that helps

Instead of punch control I took the pinion off and did the torque limiting calibration. I think I have it set at 5.0 right now. Still balloons on 3S, and its enough power to spin the tires on the track, but its not uncontrollable wheelie power now.
For 3S running I may drop the value to 4.5 for more limiting. We'll see how the handling changes when I change out the diff fluids.

Yeah after driving on the track a little the 15k does seem to make a difference, but it's still really hard to control it in air when it starts to balloon.
I may give the torque limited a try when i get a chance, seems like a little bit better idea. Before i ran the MMP/1410 combo i was running a CC Sv2 and a tacon 3300kv 2pole 3650 motor and it was actually really smooth and controllable on 3s and i really like it. But i though the mmp and 1410 would be better in the long run, but its almost too much!

Well, just got the diffs disassembled tonight and re-arranged the electronics.
The manual says the Diffs are filled 1/5/1. Thats false! The manual may say to use 1/5/1 on the diffs but in actuality they are simply greased.
I put 7/30/5. The 30k is a little heavy for a first try but I only had 1/3/5/7/30/60 to choose from. I use 150k in my 1/8th truggy to keep the 6S power under control so I'm used to running a heavy center diff.
Heading to the track tomorrow, may make some other setup changes to it as well to increase steering. Sadly the camber links aren't vertically adjustable so I can't change the roll center to modify transition response. Which is one of my favorite changes to make. :(

Well how did the 30k in the center diff turn out? i haven't had a chance to try out torque limiting yet...

Liked the changes on power. I am waiting on some parts as I snapped a rear CV Joint in half on 3S. I think it was a mfg defect instead of too much power.
Still, the changes were nice. I felt like more of the throttle was making it to the ground instead of just blowing the front tires away. I may go thicker still. I actually like it when the back end gets loose under throttle. I may swap the fluid out to 60k.
It does make the wheelie problem worse, but in that case I'll just increase torque limiting further.
