is it "safe" to run the evo 5 without the gearbox covers on? (outdoor track, smooth concrete)

Cheers

i wouldn't advise it. you can be sure that some grit will get in there and cause excessive wear to the bevel gears. why do you want to run without the covers??

because every now and then i obviously check to see if the bevel gears are worn.......and it would be easier to check them without and covers on......

also, what is the difference between the Evo 5 one way gear (51255) and the evo 5 ball diff gear (51256)?

don't be lazy just open 3 screws to check!!

the ball diff gear has the 3mm holes to accomadate the actual balls. and the one way gear has holes that you put screws through to mount onto the front oneway unit.

only if you are running a ball diff in the front. i will not work on the oneway unit.

i run all the gears dry. less friction=freer drivetrain. you do get slightly more wear, not excessively though.

on the rear diff. use a dot of diff grease on each ball and a thin film on each diff plate.

here is my mods to fit maxamps 8000 in my evo V





my firt experience was not cool , i had a frontal crash and the battery did not handle it right, the upper 2 cells slided few milimeters to the front, i did put foam in the front down battery holder to portect of frontal crashes but because the foam ws only in the down part, the two upper cells slided , nothing serious as you can move them back but this thing could be avoid if maxamps guys buit it with double side tape between each cell i think

the alu plate is secured by only the boby clips, its enough to keep it tigh as there is no slop between battery and alu plate, i needed to unscrew the metal body clips holders a little bit to get the battery in

here you can see more pics





remember this mod is not secure completly , i need to figure out how avoid upper cells slipping on frontal crash , i put a couple of rubber bands around the post as you can see in second group of pictures, but it doesnt work also , i tested with second frontal crash LOL


the blue alu knucles are by SQUARE , they did it for evo IV but as you probably know they share same knucle so it fits just perfect,good news are they are light and very strong ( i crashed the car many times and they look just perfect) bad news are they are expensive .

theese one are cheaper, and maybe strongers as they are alloy ones

http://www.rcmart.com/catalog/produc...ducts_id=23174

or there are also knucles by TOPCAD i just daw them on rc-mart but looks like somebody bought the last stock because it is not showing up anymore , t was 8.5 dollars if i remember well

I think you've got that backwards. Less grease = less DRAG, which is totally unrelated to friction.

Running the gears without lubrication will mean they heat up more, creating MORE friction, which in turn reduces the efficiency of the car.

Remember, how long the transmission spins for has absolutely nothing to do with its overall efficiency. If free-spin was a true measure of efficiency, then we'd all be running shaft drives with dry ball bearings - as this would give the most free-spin. The reality is that running everything "dry" only increases heat and friction between any surfaces that are moving against each other (ie: bevel gears) and this is amplified as speed increases.

Lube the gears with Tamiya ceramic grease. This stuff is magic and reduces noise, friction, and wear.

I've lost count of the number of shaft drive owners who have put this stuff into their car and told me how much better it was
