typically people use a high end double sided tape, NO CHEAP CRAP. Also something that has a little vibration dampening as well. the newer kyosho tape works very well as well as the clear Parma tape.

I would stay away from the sidewinder and 4600kV motor. Find a decent sensored ESC and if you are headed for the stock class, find a ROAR legal 17.5 turn motor. Some places don't allow the older style radios like the M8 with their eye-poking antenaes. It will probably still work fine but you might annoy people on the drivers stand with the fishing rod bobbing around in front of them. As far as the servo goes, it totally depends on the model and specs. I have found anything over 0.10 transit time is too slow and hampers your ability to correct and make the small, quick adjustments we need to when we are racing. For a buggy, you don't need 300 oz. of torque. I would say anything over 120 would be okay in a buggy. Don't skimp on your servo!

That's a very big ESC and space is somewhat limited in the B5M. You may have issues fitting everything in the car. If you are wanting to get into stock racing, I do not believe you can use that motor. Honestly, you'd be better off buying a HobbyWing Justock for about $50 and spending the money on a good stock motor for $90-100. Besides,

Hit the hobby shop at your track. They will sell what other racers are usually running. There are tons of combos everybody has their own liking. Personally I like Orion esc, Sanwa servo and trinity 17.5. Think you will need a new radio with all the new tech, few hundred bucks for airtronics MT4 or something like that radio will work great

Need some help here...

Today was my first B5m official race in almost a year (I run it every week otherwise).
And I had something weird with the clutch. I'm using the Avid Triad slipper clutch and I set it as I always do : Rear wheels held -> full throttle -> the car lift about 2-3inches.
No problem there in fact the car was a little bit over tighten as when I accelerated on some short straights the car would lift the front 1inch.
But here my issue I can hear clearly the slipper slipping and I basically have a lost of acceleration in mid throttle. From zero when launching the race it's ok but after a few turn I can hear the slipper go and I feel the car slow in punch.

I dismantled the clutch the thing is ok. No massive wear, everything it assembled correctly.

The guys at the club told me that this clutch is infamous for heating up and loosing it's bite.
Is this the problem ?

Thanks

Could be the diff slipping and not the slipper .

Trust me the sound is 100% the slipper. I never run ball diff I only run gear diff and today I had 5000 cst in it (rebuilt between two mains as a double check).

I use a 1"x1/2" piece on each end and one in the middle. Anymore and getting the pack out is TOUGH.

I use the clear Parma type (3M brand VHB) I got a roll from Amazon for $25 that will last me forever. It adds some cushion compared to the grey 3M that a lot of guys use.

Make sure the chassis and battery case are CLEAN! I prefer to use motor spray and a blue shop towel/paper towel. Rags, even washed rags, can have contaminants (soap/oil) left in them.

I would pull the slipper apart, scuff the pads, reassemble and check/adjust the slipper setting again.

Slipping at mid throttle is very odd.

Do you have any boost/turbo programmed into the esc at a specific rpm?
