Hey! I would highly suggest sorting your enclosure first if you’re gonna DIY it, and not buy anything else until you have that.
Here I go! 
The stuff I like:
-Loaded Vanguard deck
-85mm Orangutang Caguma’s
-2x6s LiPo’s in series
Small wheels will be fine if you have a flexy deck, and 2x lipos is the best budget way to get a battery if you don’t need much range. 2 thumbs up 
The stuff I don’t like:
Boardnamics CNC trucks are so much nicer – more axle room for pulleys with integrated bearings, no slop when mounting the motor clamps, no bending, compatible with cheap caliber 2 baseplates – if you can afford it, definitely pick Boardnamics gear over Torqueboards. TB customer service can also be horrendous.
Also, getting pulleys with integrated bearings (like from Boardnamics, lol) is 100% worth it. Bolt on pulleys are a PITA to align properly, and they weigh more and are less reliable. It takes a master builder to use them properly, and you’re only saving like 10$ a wheel. Not worth it.
Very hit or miss. I used to like it, but now both of mine have had occasional disconnects. Fine if you don’t plan to ride fast and can deal with that, but if you want something reliable – VX1 pro might be better, and a hoyt puck is reliability king. Mini remote is also a reliable option for cheap.
If you’re on a budget, use a loop-key to power your board on and off, and get a makerX DV4. Super cheap V4.12 ESCs from other companies will die from the 12s voltage and take special care to run without dying. If you can find some used focboxes that would also work, but might not be any cheaper than the maker x offerings.
