[NSRCA-discussion] Electric vs. Glow

Fri Feb 17 16:07:02 AKST 2006

2 x motors add another 					$455
2 x speed controllers add another			$210
4 x battery packs add another			     $1200
-1 Deep cycle battery				     -$100

Total additional					     $1765
Previous total					     $3960

Electric setup					     $5725

Glow setup

Abbra								$1300
My motors/servos/odds and ends			$0
Years Fuel							$300

Glow Setup							$1600

Because of the short flying season here I would want backup motors/speed
controllers.  I have backup for my glow.
Granted, here in Alaska I have 2 contests.  Would love to make it contests
in the lower 48 but the time and cost is too much.

As has been noted, I plan to make the jump to electric in 2006 - I'd offer
the following costs -

$1,300.00 - Abbra (www.EScomposites.com).
$455.00 - Pletty 30-10 (www.Icare-rc.com).
$210.00 - Castle Creations Phoenix 85HV (www.CastleCreations.com).
$1,200.00 - 2xTP10s4p 5300 (www.Draganfly.com - best prices I've seen).
$35.00 - Budd softmount (www.BuddEngineering.com) $250.00 - 2xAstro 109 lipo
chargers (available many places).
$100.00 - 1 12volt deep cycle marine battery for field charging.
$150.00 - Iota DLS55 power supply (55 amp) - available many places, use for
home PS and recharge of 12 volt field battery.

$3,690.00 Total.

The above is absolutely competive in F3A and all of it is reasonably easy to
get.  You could spend more/less on any of the above items, but as listed,
depending on the number of flights, the cost is certainly comparable to a
decked out DZ setup w/ softmount, header, CF pipe, etc, and the support
equipment and fuel to go with it.  If you want to fly back to back, you'll
need 2 more chargers ($250.00) and 2 more sets ($1,200.00) of lipos, but
what is listed should be good for at least 200-300 flights - at which point
all that might be needed is new lipos (which continue to drop in price and
improve in performance).  Compare that to servo repairs, airframe vibration
repairs, umpteen gallons of 30%DZ fuel, the engine in the plane, the engine
being repaired, and the engine in transit to/from the repair shop,
....etc....and make your choice.  And the price could be reduced using an
AXI (definite weight penalty) or one of the soon to be available Hacker
outrunners (also a weight penalty) which are in the $250.00 range.  For
Sportsman, Intermediate, and Advanced, the TP 4200s have plenty of capacity
and power, and would save another $160.00.

FWIW - I will be changing to electric because the perception is that the
electric is better, and I will have more options for practice fields.  Kind
of amusing on both counts - as my Webra setup is substantially stronger
(appearance-wise and by the numbers) and the noise levels of my glow and
electric setups are within 1db.

For the record, I've happily purchased products from all the companies I
noted, some of which are current sponsors (and I've done beta testing for) -
- Castle Creations for ESCs.
- Budd Engineering for mounts.
- Horizon help with TP lipos (as they carry TP and I am part of Team JR
through Horizon).

I did a lot of reading, and contacted a lot of people for information.  To
date, I'm quite happy with the Pletty/CC/TP setup in the Abbra and I've only
had a few minor issues which were easily remedied for little or no cost.  I
plan to bump up the power output when the weather is warmer (lipos don't
like the cold) and try some other motors (Cyclon and Hacker) in addition to
the Pletty.  And I can't wait to get the pair of Prestige planes in the air
as they will be 3-5 oz lighter, putting them under the 10 lb mark at takeoff
(compared to my Webra powered Vivats which are 9.75 lb dry and 10 lbs 8 oz
at takeoff).

A long time ago, it was posted on this list that electrics were not for
everyone and probably never would be - still sage advice today - eh Mr.
Shulman?
