Radio Equipment, Speed Controller, Battery Pack, And Connectors
One of the very reasons that indoor models such as the Antoinette are now possible is the fairly recent availability of good
quality, reasonably priced light-weight micro receivers, servos, and speed controllers (ESC's). Up to this time, such equipment
was only available from small, highly specialized sources at relatively high prices.
Here are the airborne system components we've used in the Antoinette.
Item
Weight
Maxx Products (MPI) #MX-6800 Pico 4-Ch Micro Receiver, w/crystal
8 grams
Maxx Products (MPI) #MX-30 Pico Servos
7 grams each
Maxx Products (MPI) #MX-9104 Micro ESC (Electronic Speed Control) 1 gram
7-cell 350mAh Ni-Cd (nicad) Battery Pack
95 grams
7-cell 500 mAh NiMH (nickel metal hydride) Battery Pack
96 grams
These are the components that are shown in this manual and on the plans. We did not use an On/Off switch in this airplane
because of weight considerations. The battery is simply plugged and unplugged from the ESC before and after each flight.
Different brands of receivers, servos, and ESC's may be usable with this design, provided they are the same weight and size or
lighter. For obvious reasons, standard size radio components cannot be used with the Antoinette.
A 7-cell 350mAh Ni-Cad battery pack is used in the Antoinette to provide good flight
duration. With throttle management, this battery pack will keep the Antoinette flying for
anywhere from 8 to 12 minutes. We've also used 7-cell 500 mAh NiMH (Nickel Metal
Hydride) battery packs with good results. In general, the difference between this type
of cell and the 350 mAh NiCad cell is that the NiMH pack seems to deliver a little less
power with some incremental increase in duration. Both types of cells weigh the same,
so they are both usable. Last, the battery pack should be configured in the "hump"
shape - four cells on the bottom, three cells on top. This layout offers the most mass in
the least amount of space and this is very helpful when making small changes in the
C.G. location, if needed.
For maximum flight performance, indoor R/C
models require attention to the weight of
everything they must carry aloft, including
connectors. We used and liked the small 2-
prong Dean's connectors for connecting the
battery pack to the ESC. Recently, Cloud 9
Micro R/C announced the availability of their
new micro connectors. We've seen and used
these and can recommend them for use with
the Antoinette. There are many other
connectors available on the market. Be sure to
choose your connectors with weight, size, and
efficiency considerations in mind.
Last, our radio systems include excellent
transmitters, providing us with features such as
servo throw adjustments (EPA), servo
reversing, servo sub-trim adjustments, etc. Our
trusty Airtronics® RD-6000 Sport transmitters
and the equivalent HiTec units have taken care
of all these needs.

Paint
Since fuel proofing is not an issue with electric powered airplanes, the only reason to paint any part of the Antoinette is to
improve the scale appearance of the model. And because light weight is so important in an indoor model, we’ve tried to keep
the painting on the Antoinette to a minimum. Too much paint, or the wrong kind of paint, can add unnecessary weight in a hurry.
