Another thing you can put together easily is the LED Lights for you jets. My friend Ben Burdin from Lima Ohio have perfected it and those that attended Hearts Of Ohio Jet Scramble or Spideman Jets at Winamac would attest to how great his system works. Just do an eBay search on 12 cluster bright LED bulbs on eBay and get your soldering iron ready and you could put one together easily.
