I bought one from there a couple of months ago. Took about 2 weeks to arrive and came UPS once in USA. Shipped initially from France by Colissimo. I would by from there again.

Have any of you guys tried 7-5-3 or 5-4-2 diff oils ? Im wondering how good it would work in this buggy. I have 7-5-3 in my tekno sct410 and it works good.

7-5-3 worked ok for me, but I also tried 10-7-4 and 7-7-4 because I don't like too much corner entry steering, for me, the MP9 has too much off-power front grip for my driving style.

I noticed very little loss of steering when going to a thicker front diff but it all depends on one's driving style. If you use a 'slow-in, fast-out' style, then off-power grip/steering at corner entry isn't all that important. And in all seriousness, slow-in, fast-out is the only way an off-road vehicle should be driven, as shown by the past 40 years of rallying, motocross racing, ice-racing, etc. Try to keep up some mid-corner speed when racing on ice and you'll know what I mean.

But it all comes down to each person's personal preference, so what may work for me or you won't necessarily be any faster for someone who's not used to driving a limited-traction or an over-powered vehicle, which is exactly what our RC cars are.

Everyone has their own theories and preferences.

I've run a lot of different combos - 7/5/3, 7/5/4, 6/5/3, 6/6/3, 5/6/3, 5/4/3, etc. I always end up back at 5/5/3. For me, 5/5/3 is completely balanced and the car feels like one piece. When I started increasing my front diff, I did get a lot of pull out of the corners with almost no reduction in initial off-power turn in like aaron125 stated above. However, this increase in on-power pull came at a price - it almost felt like the rear end was detached from the car. If anyone has seen a very high-powered front wheel drive car before, you know what I mean - the rear end sort of wags around and is just along for the ride. I know this is greatly exaggerated, but hopefully you get the idea. This is also just what I felt, your experience may vary.

In my testing, I found the diffs on this car to be very sensitive to 1k changes in oil viscosity, so I never felt the need to go up to say 10 in the front or center. Diffs are very subjective too - track conditions, driving style, ability, all play a factor in how they behave and what you feel as a driver. What you feel might not be what someone else feels also. I'd suggest buying a couple spare diffs and have them ready to drop in so you can test different combos fairly quickly at the track. Start with 5/5/3 and tune from there.

Whats your thoughts on the MP9 TCD diff when used in the front, Elliot Boots over here in the UK seems to be quite a fan.

I have used 5-5-3 and i went to 5-7-3 and i like it. I was just thinking about trying something like 5-4-2 or 7-5-3 What brand oils are you using Sean ?

I haven't really had the time to try it to be honest. Also, our tracks over here don't tend to lend themselves to a TCD diff - they're so rough during the mains that the diff would constantly be in a state of flux. Some tracks I've seen in Europe are as smooth as glass comparatively. All that said, I'd still like to try one...

I run Kyosho oils in my diffs. I used to run another oil when I first switched to Kyosho because that's what I had left over. I did notice a difference between another oil's 5k and the Kyosho 5k for instance, so I'd suggest sticking with one brand for all your diffs. For my money, the Kyosho oils are right on par with the rest of their products - top notch. The only time I drop lower than 5 in the center diff is if the track was incredibly blown out. Otherwise, I'm at 5 almost exclusively in the center.

Sean,

What about extremely high bite and hot outside temps? Do you think going up to 7,7,5 could be beneficial?
