Track Surface
Hello TO ALL!
I'm a new user on this forum, but I've been watching you some time ago and I really enjoy the very nice information, pictures and reviews the people over here make! I'm from Greece and we have started moving this 1/10 Off Road category in Greece also this last year after some years of decline for this category. I'm no.1 for the moment - one more race to go, at the Greek National Championship Off Road 1/10 4WD and have been racing a badly tuned hybrid Schumacher CAT2000 - CAT98 - CAT3000 which you can see on the photo! I just wait HB D4 to arrive here in Greece and get one for next year's Championship! Please give me some info on how to prepare a track surface like the one in the picture with Hara - Worls Japan, because we are preparing a new track over here and would need some help. On every other track we have made, it becomes very dusty and bumpy after a simple race day and we were wondering if we make something like that is it going to have better wear resistance???

You are fortunate to have great weather to produce a great surface - except for grass I guess. The trick to making the dirt/clay stick together, and not turn dusty or bumpy is regular watering between heats - and laying down SUGAR, and watering it into the surface. This will produce a solid surface which is extremely high bite even with worn tyres, the type of surface which will suit the Losi tyre - BK Bars. Anyway, there is plenty more knowledge from others who visit this forum, so expect lots of ideas  Chris

Many thanks for your reply Chrislong! No grass here in Greece my friend. Looks like the surface needs almost same treatment as for onroad. Good idea the sugar to make dirt stick together! Maybe a heavy cylinder would also be needed to flatten the surface eh?

A heavy cylinder, such as a roller, or something else which will compound the surface would work very well. Water and sugar to make it stick.
I would not use concrete and tarmac like for onroad, I think dirt and clay would be a better choice, and sculpture it well to have flowing jumps, bumps, and contours to drive over - plus it can be changed every so often if you have the diggers, manpower and compounders. Have a look for some events in the USA, such as the Losi Race, Cactus Classic, CRCRC etc.. as these will give you some great ideas Chris

The jumps we used to build round by my home (bmx jumps!!) were high in clay content so they would break up in the summer if we didnt water them a bit.
Tricks we used to keep them together were coke or cheap fizzy cherry drink!! worked better than just sugar water. We'd use a roller to compact the transitions on the jumps and any flat areas that we needed to.. but you have to be carefull as if you roller it when its to wet you'll end up with holes as the dirt will stick the roller. I'd seen some people use those vibrating compactors to better effect on flat sections than rollers.. if you have a machinery hire shop near you have a look at how much they are to hire. erm only other kinda tip is that we also used to pour petrol on the transitions and light it to dry and bake the surface.. only really works if theres a good bit of clay in it and the earth is wet.. dry earth just breaks up quiker..
