If the rear end is too loose, then you need to lighten up the oil in the rear diff or fill it only half way. On loose parking lot or low traction conditions running just grease with the 4 gear mod is too much, so it really depends on how much grip you have. The other thing you can do is to go to silver (softer) rear springs. I raced on a different surface last year and was having oversteering problems. I knew the rear diff was too tight, but I put on silver rears and it handled great, so I left it that way.

I dont think he has even raced the r40 this year. I think his game is pretty much focused on the cyclone.

If your track is also used to converting setups to rubber im sure you can get it going. The downside though , there is no rubber setups avaiable from hpi. All you can hope for is personal setups.

I have run rubber tire with good results. Usually in low bite or dusty track surfaces where the foams just won't hook up. I run pretty close to stock settings, the only change I make is to use a little less camber.

Anyone tried a solid front diff? What is the advantages of a solid diff over normal diff and oneway.

I know the oneway has better drive out of the corner than a normal diff. (but no braking).

I've used 50k oil on the diff to stiffen it up and it helped alot. I've also build a solid diff today, but would like to know what the advantages and disadvantages are for a solid diff.

I remember some saying the solid rear in the front pulls the car more in turns like a oneway, but remember the wheels are moving at the same rate of speed. They both will have the same amount of traction whether on and off power. I have the oneway and 4 gear diff and indeed the car is a lot faster in the turns and better than diffs on all 4s. It is beneficial to have a setup system now though and definately try different oils. I'm only running the OS .12tr, but in a lightened R40 the TR is fairly impressive and also being on 30 %. I had ideas of selling the old one again for a newer kit now that my paychecks can now be going towards RC. Fast harry, Sry about before, but it wasn't me burning you - just that every time I had some $$ it had to go somewhere else first...90% of the time was to the credit card bill my mom get since she was kind enough to let me use it twice to pay off my car insurance. If I did have the $$ in hand I'd buy your Hara in a heart beat. I appologize again man. Regardless, there's been too many shifts in race scheduling for nitro onroad so I may just take a break from it and join the elec scene. I've been thinking of a Pro 4 or some other elec onroad. I have an ELEC offroad on the way, but soon will get a buggy and onroad.
