[NSRCA-discussion] cost of electric

[Fred Huber]

The costs they listed are for a plane competitive at Masters or above. 
Sportsman simply doesn't require the same performance from the model.  (each 
successive level demands more from the plane and pilot)

Sportsman (flying the schedule used the past couple of years) level needs 
appx 100 watts/ lb and you can get a decent e-power plane set up for close 
to half the cost. (probably less, as prices are comming down)

It depends on the performance level you want or need.  I believe the setup 
Nat recommends approaches 200 or 250 watts/lb in an 11 lb plane... 
Desireable for the HUGE verticals with rolls on up lines at Masters and FAI 
level.

*************

BEST is to charge the LiPos at no faster than 1C rate... so it takes 1 hr 
for a fully depleted pack.

don't forget to get a cell ballancer, and a Wattmeter.  Adds appx $75 to the 
bill. ($25 for Astro Blinkey... and $50 for the wattmeter).. but the 
ballancer increases the life of the LiPos, (and makes charging safer) and 
the wattmeter allows you to test the power draw with assorted props, to 
ensure you aren't overloading something.
