The two antennas should be placed at 90 degrees to each other.
The main purpose of the photo demonstrates how the antenna should be placed.
‡ The receiver contains precision electronic parts. It is the most delicate radio component on-board the model
and should be protected from temperature and other extreme conditions.
Allow air to circulate around the receiver. One tip is to utilize small foam blocks like standoffs to ensure
that there is an air channel around the receiver.

If appropriate, waterproof the receiver by placing it in a plastic bag and closing the open end with a rubber
band before wrapping it in foam. If moisture enters the receiver, intermittent operation or a failure may
result. Wrapping the receiver in a plastic bag also protects it from fuel and exhaust residue which, in some
models, can work its way into the fuselage.
Powering the Receiver-
It is imperative to properly power the receiver and onboard equipment. The receiver battery, or onboard
power supply should be of the design which will enable all servos and other equipment to maintain
functionality throughout the flight without any inadvertent interruptions in the supply of power to the
necessary equipment.

As the receiver power needs vary significantly from model-to-model (for example, a .40-sized trainer
will require a smaller battery than would a giant-scale aircraft), it would be difficult to make a general
recommendation. As such, we would suggest that modelers refer to the suggestions of modelers with similar
