freerida, 407 $$ ??? man thats high....
Its not always easy to afford new stuff for a lot of people, nor would i recommend a nitro n00b to a new rig, mainly because its a costly affair if the rig gets trashed within the first few outings. i came in on a Thunder tiger eb3 near the end of the engines life, it ran like a champ, taught me a LOT about nitro and tuning issues etc etc. it was a gift, which was sold on to finance an EB4. That has since had the best possible care due to the learning i did with the eb3. Yes i crashed ALOT, yes i repaired it, but by the time i had my new rig, i knew i could handle it and know how to tune and look after the thing.
I have since bought a pair of used Revo's, a 2.5 and an incomplete 3.3 conversion. The 2.5 simply needed a new primary clutch and clutch shoes and the thing runs like a champ now i have it tuned right. Not everyone lucks out and gets a lemon.........
My point, is that i ALWAYS assume an engine is dead and also that the servo's are dead as well (unless demonstrated otherwise) when i buy a used rig and i would suggest others to assume the engine is dead as well as the servo's. If teverything works, then great, otherwise its not a suprise if niether item works.
My advice would be to caefully strip the revo bit by bit following the manual (downloadable from traxxas) and carefully check each part before re-assembly. other things i personally do, are change out the shock oil, check the clutch shoes, the slipper pads and swap out the glow plug for a brand new one before attempting to start the engine.
