2 Many Problems Plz Plz Help!!!

[Calsonic_racer]

hey my bit racer axles FINNALY came in. it also came with the 7 tooth pinion everyones used. k so i install them on my 3.8 motor and i put it in my chassis. next i shave the spacer on the bit racer axles so they fit properely. spins freely in the chassis. but the thing is sometimes the gears get stuck and i noticed that sometimes the pinion gear isnt even touched the idler gear. i tried the red gears, blue gears, and the green gears and none of them fit PERFECT like my bitchar-g axles do. how do i fix this? is it my motor? i noticed if i didnt push my heat sink all the way it fit perfect but loss in speed and torque. any suggestions plz?

next problem is on my clone car the spring broke so i took one out of my broken down cars and everything seems ok kind of. then i charge it and let it fly. but i noticed that now right is now left and left is now right?? i juss got the clone today and im like wth? also the wheels stay to the right ALL the time i changed the magnets, tried the ITS TWISTED wire, and i checked for shavings. so my steering is locked to the right and my directions are swithced. what should i do?

next problem on my bitchar-g. this is my MOST reliable car and it hasnt let me down. because of this i havent done any mods except putting the best stuff i could put on it (3.8 perfection, bit axles that dont fit haha, alluminum heat sink,) well 2day i took a chance and tried the laymans tri cell which came in 2day. fit perfectly but i went 2 fast and hit a wall. now my steering only turns left and not right. i soldered the wires back 2gether and its still the same. also now this car ALSO is locked to the right!!!! so it cant turn right but its locked in that position. i tried everything like in problem #2. plz help??

also if you can plz can u possibly send me a few steering springs for free? ill pay for postage of course. maybe 4 because i hear using 2 springs really helps. but if anything if you got one to spare plz can u ship it 2 me cuz this has been bugging me for 2 weeks and i havent drivin a normal car and im going CRAZY.
