-
- I've got a Concept 30 DX that I've upgraded with new parts so that it
- is approximately an SE now. The aluminum paddles have more mass than the
- plastic ones, making their response to control inputs just a little slower.
- They're worthwhile to use while learning, especially hovering.

- I've got a Robarts gauge that I like. Setting the pitch of the main rotor
- blades is done relative to the flybar. The Robarts system has a quickly
- attaching arm that locks the flybar into an adjustable position. A small
- bubble-level (comes w/ the package) is hung from the flybar so that you
- can set it level. The pitch meter is attached to the blade and uses simple
- gravity to move the balance needle that tells you the pitch setting in
- degrees.
-
- I've seen other systems that have things extending from main blades that
- you sight against the flybar to read the pitch angle. It seems less
- precise. Of course, two different pitch gauges are likely to be at least
- one degree different in their measurements of the same blade. :-)

-
- I've got a wooden box from Custom Woodcraft (they advertise in the AMA
- magazine) that I really like. In fact, I know three other people who
- have them and also would use nothing else.
-
- >> - (trickle?) charger for 12V battery (flight box battery)
-
- I've got a Hobbico MAFREC battery that I charge about once per month
- using a cheapo 12v charger. I wouldn't worry too much about that. Don't
- scrimp on the care you give your flight batteries.
-
- >> - #64? rubber bands
-
- You'll only need them to connect your heli to the training gear. Any
- size will work. I use the leftovers from the box I had for a fixed-wing
- plane. (Sold it, BTW, cause rubber banding a wing is a real pain. I much
- prefer bolt-on wing planes.)
-
- For training gear on the heli, you could try to find a hula hoop. Mount
- four wooden dowels inside it with duct tape so that you have a square
- in the center to rubber the heli to. The hoop will slide better on grass
- than the dowell/ball assembly and provides protection on more directions.
-
- >> - other?
-
- Buy another set of main blades and a spare boom now :-)
-
- >>Why I'm posting:

-
- No specific warnings, but you should definitely make sure that you've
- got it mechanically set up perfectly before the first flight. Have an
- experienced pilot help you set it up, and then fly it.
