Receiver Packs for Sport, Scale &
Pattern/3-D Aircraft to
15 lbs
Once the domain of casual trainers and sport flyers, the
.25 to .90 sized R/C airplane of today is far more likely to be a retract equipped Scale Warbird or a U-Can-Do 3D type aerobat
than a Sig Kaydett or Senorita. As the number of flyers operating faster, stronger more aggressive and complicated aircraft
increased, radio system manufacturers followed suit by making available stronger, faster and higher torque servos. On
today’s .60 size aircraft, retract systems, glow drivers and/or high output-high speed servo's are commonplace instead
of extraordinary. I
find it amazing that folks still try to fly these planes with a ‘factory’ provided pack, when they’d never
for a second use the ‘factory’ provided servos for anything much more demanding than operating the throttle in
the same plane.
Today's new radio
systems take good advantage of computer technology and are designed to compliment and refine this new
breed of R/C aircraft and style of flying. Yet, after nearly two decades of systems development, we're still seeing that same 600ma pack provided as
OEM in the set and in the box. If you've got a high output servo system, handling a plane doing aerobatics Gramps and
his Kaydett can't even name, it follows that you should consider upgrading to a pack a little more competent at delivering
power in a high load environment than Gramps' battery pack.
Using the Impedance Rating
to pick the right pack for the way you Fly.
Most folks
react to the 'capacity' rating alone as being the biggest part of their decision in selecting a pack for their big aggressive
birds. This can lead to big trouble on board the aircraft. Just as cells are evaluated for capacity, in high load applications
you need to take into consideration what the cells voltage performance will be when loads are applied. All battery technologies
react to servo loads with a voltage drop while the load is applied. It's really very simple.. the higher the cells impedance
rating, the greater the voltage drop will be while servo loads are applied. Rule of Thumb for cell selection: Impedance
Ratings are like a Golf Score. The lower, the better. Aircraft in agressive aerobatic enviornments employing digital
high torque servos should shoot for a combined impedance score of 10 mOhms or less. As an example, one of the
most popular lightweight packs used in IMAC aircraft is the Sanyo HR 2700AUX.. plenty of capacity, but the impedance
rate on the cell is 20 mOhms. Pretty high.. but if it's used in parallel with another 2700 pack the impedance rate is cut
in half to 10 mOhms (and the available capacity is doubled). Which is why you usually always see this pack employed in parallel
in IMAC birds and used without issues as a single pack in a big scale Cub.

Sanyo Eneloop NiMH Rx Packs
|
2000 Series AA Sanyo Eneloop NiMH
Rx Packs - I've been having my arm jostled for
years about adding the eneloops as Rx packs.. after 4 years of use of these in Tx applications they have proved themselves
to be excellent performers. If you are a sport flyer with smaller aircraft that can only fit AA sized packs, fly occasionally
or are just looking for a pack you can charge on Monday and use of Friday, then this may be your solution. We have made them
available as 4 or 5 cell packs, flat or square and the price includes a standard 22g JR/Univ connector appropriate for all
common radio system types. - The Sanyo Eneloops are unique NiMH cells and have proved themselves outstanding performers in low current
static environments. The charge retention is outstanding and when properly cared for provide years of dependable service.
It must be noted that using them on board the aircraft as Rx packs opens up a a big can of worms... these cells are fragile,
can be easily damaged by aggressive charge routines and should not be used in high temp, high vibration environments as that
use pattern can degrade the cell rapidly. It must also be noted that these cells have high internal impedance.. use of these
packs in aggressive high drain applications and/or with high load digital servos is NOT recommended. - Eneloop Care and Feeding Notes: Eneloops arrive with aprrox 50-70% of charge
in them.. the cells have been pre-formed and tested by Sanyo (this is the only cell they do this with) AND ARRIVE WITH A PARTIAL
CHARGE IN THEM. DO NOT OVERCHARGE THESE PACKS! Eneloops should be slow charged at approx 1/2 of the usual C-10 rates..
for the AA 2000 approx 100-120ma OR LESS. Peak (fast) charge, if necessary should be a bit less than 1/2 the
normal C rate.. for the AA 2000 at 1 amp or less. USE TEMP CONTROL.. when the pack warms up (fast or slow charge) STOP
THE CHARGE. - WARRANTY: We offer
a non-DOA warranty on Eneloop Rx packs.. there is no warranty for capacity, duty cycle lifetimes, etc.. again, I must emphasise,
these cells are fragile, purchase and use is entirely at your own risk.

A NiMH Rx / Ignition Pack
Cell Size: 2/3 A Type: High
Rate NiMH Dimensions: .67 x 1.1 Cell
Weight: .7oz Impedance: 7 mOhms |
The Elite 2/3 A High Rate cells pack a surprising amount of capacity in a small
footprint. Coupled with it's low internal impedance and light weight this has become one of our most popular NiMH
packs for DA Ignitions. It's also found a loyal following among the smaller 3D and IMAC pattern crowd and it's ideal
for 2.4 GHz Rx's with digital servos. We often see these run in parallel with dual switches on 25% sized Aerobatic Aircraft in
agressive flight routines. Available with a wide array of primary and secondary cabling options, this is a very versatile,
small & lightweight NiMH pack that will handle high current demands in most applications easily. |
Available as 4.8v (4 cell) flat, square or 2x2 stick pack, or 6.0v (5 cell)
flat or 3x2 square pack. Built with extra HD Quadruple Welded 1/4" wide straps & finished in HD Rubberized 3M MilSpec
shrink.

'Kero Start' Turbines can dish out, and configured in either 'Flat', '2x3 Stick' or '3x2 Brick' shapes. Connector and
wiring options for most applications are available, including a second lead with a standard system connector for easy installation
of a charge port for checking and charging ECU packs without the hassle of digging inside the plane. We reccomend 18g cabling for all
ignition applications and the 16g cabling for ECU or other high current loaded applications. For a second lead to
handle charging on a pack with 16g cabling select 'add 22g JR/Universal lead for charging'. |

2100 Series 'AA' Rx & Ignition Pack -
The HR-2100AU Series Rx
& Ignition pack is a popular favorite in larger sport scale models and it's also being used in place of
the 1650 AA NiMH packs in pattern planes. For the big 3-D birds, it's best used in a Parallel Pack system with dual switches
to cut voltage drop relative to impedance and improve total flying capacity. Small footprint & light weight. Ships with HD
22g leads and either Futaba or JR/Hitec/AirtZ connectors.

|
Cell Size: Full 'A' Type: Medium Rate NiMH Dimensions: .67 x 1.99 Cell Weight: 1.3oz Impedance: 17 mOhms
|
The 2700AFH carries the same full-size 'A' footprint as the Sanyo Nicad 1600 at about the same impedance
rate. This makes it a suitable candidate for 3D aerobatic birds when used in parallel with digital servos. With
capacity higher than physically larger nicad Sub-C's and with significantly less weight this pack will fit where others
won't with a capacity punch above it's weight class.
* For high
drain applications (33% sized birds and larger) this pack should be run in parallel with dual switches to spread current loading
across both packs. Run as a pair, these weigh only slightly more than a single 4000 Sub-C pack and yield better than 5,000ma
of airborne capacity. |
Available as 4.8v (4 cell) flat or square pack, or 6.0v (5 cell) flat or 3x2 square pack. Built
with extra HD Quadruple Welded 1/4" wide straps & finished in HD Rubberized 3M MilSpec shrink.

We reccomend 18g cabling for all ignition applications and the 14g cabling
for ECU or other high current loaded applications. For a second lead to handle charging on a pack with 14g cabling select
'add 18g JR/Universal lead for charging'. |
