Electronics You Need To Get Started

Here's pretty much the electronics you'll need to put together your first plane (not counting transmitter/receiver).

Clockwise from upper left:  LiPo battery charger, brushless motor, servos, electronic speed controller (ESC), battery voltage checker, LiPo battery.  In the center are bullet connectors (note the bare wires on the motor) and props.

Here's some notes on how much these things cost, cribbed from an email I sent to MarkV over at the Brain Wagon:


here's the build list, which I tried to make as complete as possible.  let me know if I left anything off!

everything's from except for carbon fiber, epp foam, and glue which are from  all the numbers are what I paid including shipping.  all the zero items are things i've got excess sitting around from buying bulk quantities.

traditional glue is hot glue, but i like the foamtac coz it's a bit lighter and (imho) more resiliant.  try gluing a couple of pieces of scrap foam together and if it doesn't give you zen tranquility then use hot glue, keeping it as light as possible.

the epp was more expensive than i remembered... it was about $60 for 6 sheets, not 10 as was my recollection.  I'll stop everything off in the morning and we can check out the tx/rx if you've got batteries...
