I found the 808 to be high maintenance, but a joy to maintain.

put it this way, there is no such thing as a low maintenance beauty queen...

the Achilles's heel of 808 is probably the pinion bearing assembly, which can be solved by regular maintenance and changing out worn bearings religiously, other than that it is virtually bomb proof...

F1 cars are hand rebuilt almost after every race...

Default the 808

Easiest buggy to work on in my opinion. Changing the bearings is cheaper than some of the stuff in other cars. I've never had any issues with my 808. You heard right, change the pinion bearings every 5-7 races and you will be set.

Default 809

2-3races: -pull front and rear diffs, check mesh
-Pull the pinion out and regrease the center CVD's
- regrease the pinion bearing or replace. Use no seal on the side of the bearing that faces into the diff. Pack that unsealed bearing extra full with Lucas Synthetic grease with antisieze.

5-6 races:

-all the above +
-change diff fluids, regrease diff outdrives, flip the outdrives
-refill shocks if needed, mine don't leak!
- disassemble CVD's clean and grease
-regrease wheel bearings, or replace as needed
-polish up the hinge pins
-flip the axels so the other side wears.

10 races:
-above plus
-replace shock oil
-replace shock orings, shock bladders, if needed
-replace DE skidplate
(an AE RC8 would need nearly every single plastic part replaced about now! LOLz, Xrays plastic will still be fresh about now)
-new body
-replace dog bone pins

This car is the tougest 1/8th scale I've driven so far. But better racers tear their stuff down alot anyway. You don't replce parts as fast as other cars, but you still need to maintain them.

I agree with Zerodefect completely on his maintenance plan. I change shock oil continuously because I race to completely different tracks on a regular basis.

I can add is to watch your front and rear arms. They will warp with time and use. I cannot put a timeframe on it, but they will eventually. The first set did not last very long before they warped. Since then, I have removed shocks after each race day and that has helped. I am on same set since racing started in late March.

Watch your dog bone pins as well. They will flatten with time. Usually will change mine once or twice a season. Take care of those and you will not have to replace diff outdrives.

Clutch is just like any nitro car. I clean the bell and de-burr the shoes after each race to prolong life. I am anal and have never had a clutch bearing fail, but replace each week with $1 Avid's x 2.

In the '09, I have never had a problem with pinion bearings using the spacer. If you do normal maintenance, you will never have problems with them either.

Depending on how dusty the track you race on is, you main to check moveable parts more frequently.

I have uncountable gallons on my car now and have not had to replace any of the ball joints beside one that was damaged in a head on crash with someone flipped in a high speed straight. Mine still has less play then a brand new losi.

Awesome car, love mine. Was daunting at first with all of the setup options, especially active diffs and overdrive 41t diff. I can now get my car to work well others struggle.

Nitro cars are work, but well worth it.

Exactly, except worse than that. They're often rebuilt between practice and qualifying. Then again between quals and the race. It's pretty retarded.

that's wat u have to do if u are at the pinnacle of racing... the search for ultimate performance resulted in super light weight parts, coupled with extreme working stress, they sure won't last as long as my old toyota clunker...
