So I bought this thing on marketplace for $80,It was broken. The servo saver assembly was broken and was missing some screws whatever, came with 2s li po and some spare parts like cvds, swing arms,hitch pins etc. I get it home look at it order servo saver and 2 3s zeee shorty li po's on amazon ​and I get them and I try to fit the new spiffy cool blue aluminum one on and everything bolts up fine but the arm that connects the servo to savers mount point.. holes too small but I want to ride this thing so I put the old plastic bottom piece because I know the hole is big enough and they dont mesh right! The plastic halve comes to a finer point than the metal cup it sits in. So whatever I want to ride, I tightened the servo spring to the max so i can at least attempt to drive this thing and well it works... sorta.

Have to address that later cause its already a problem not staying true, guess the mjx gyro I installed helped keep it straight enough. Lol

Anyway I get it on the street and yeah I wasnt ready for it. No wheelie bar I wasnt thinking and sent it and it went nose up of course and scrapped up the wing and came back down. So yeah im happy and I get it up to what I believe was to be like 40 or so and I punch it and it goes nose up again! This this is fast and I would say my mjx clocked in at 46mph GPS tested and this thing feels like a rocket compared to that so idk what it does but it has to go at least 55 or so??

But.. I want it to be just a liiiiiitle bit faster, maybe like 65ish??

So im sorry about the long story for whomever is reading this, I asked Google aI for what the specs are for getting a bigger pinion gear set and it tells me its a pitch48 with 3.175mm aka 1/8 bore so I get a set on amazon with those dimensions 29t-32t. I counted the t count on existing one on it and it counts 44t spur and 28t on pinion. I did the math I believe correctly and every tooth jump adds roughly 2.5 mph. I wanted the 30t none of them fit at all. Im pissed I did more research, called Google out on giving me wrong information and it apologized and gave me ACTUAL correct dimensions.

ITS A MOD 0.7????

I looked and cant find ANYTHING! Im frustrated.

I also ordered a adjustable motor mount to offset the motor when I put in the bigger gear and the thing bolted up to chassis perfectly but then I put motor to mount and the holes dont line up!! What the hell everything is against me on moding this thing. Im lost.. I cant find the right spur gear either.. I want a metal one not the plastic one and I again order a spur pinion combo and the teeth are exactly a match everything fits but... on one side the dimensions again were not true on one side and the bearing would not go over the center where it was supposed to be.

Can someone please for the love of god create me a parts list to get to 65 with out completely going over to something different? I just want gears that I can throw in this thing and a spur gear that is metal.

Tips, hacks, anything helps.
