He does make a heavier brass tray if needed.

Thanks guys for your replies and sharing your experience, sounds like I'm on the right track here.

The new 7940 servos are slightly heavier (15gr together if I'm correct) than my current futaba brushless servos so a little increase there.

It really depends on the engine and the grip level on the track.

For me, .3 would bog the engine way too much and not let my car come out of the hole the way I would want.

Guess i will need to try different settings

By the way my first and second alum gears are getting chewed quite fast whaever the mesh tight - loose.

Is this a normal issue, shall i use steel gears? or maybe their is a hop up which can whitstand more abuse

They do not make a steel spur gear for the RRR.
If the mesh is correct, you spur gears will last quite a long time.
Check your spur/pinion mesh, check your rear lay shaft for wear, bearings for the rear lay shaft,clutch bearings,pinion gears for wear for starts.
There are many reasons why you are going through spur gear so quickly, and it could be the mesh is too loose, too tight, of parts have worn to where there is play between the spur/pinion gears
I have had my spur gears on my RRR for well over a year, and they still look great.

actually the plastic spur gears are quite fine its the aluminium gears that are getting chewed.

I tried a tight mesh with obviosly a bit of play and i tried a mesh typical buggy / truggy.

The two of them didn't work.

I heard that you really have to tighten them, do i have to tighten them as if they are binding?

It sounds like your pinion gears may be worn out. If the very outside tip of the pinions are very sharp and to a point, then they are worn out.
Try new pinion gears and when you set the mesh, rotate the gears very slowly until you find the tightest mesh between the pinion/spur gears. Back the mesh just a touch, and then tighten the down the engine support bolts.
There is always a loose/tight spot bewteen the spur gears and pinion gears.

The aluminum pinions do wear a bit fast. The first gear pinion will wear faster than the 2nd gear pinion. You can run steel pinions and pretty much they will last forever, or at least run a steel first gear pinion.
