DMAC Frequency Control

D.M.A.C. operate a Peg-off transmitter frequency control system. This system will be explained to you fully on your arrival. The basic rules are -

Make sure you know which frequency you will be using. Check the crystals!!!
You must have the peg number which matches your transmitter frequency before you switch on your transmitter. If "your" peg is not on the pegboard, it means that another member is using that particular frequency and that you must not switch on.
When you are ready to fly, take your transmitter and the appropriate Frequency Peg. Enjoy your flight and when finished, switch off your transmitter and return the peg.
If you use 2.4 GHz radio then interference is not an issue but pegs are provided so that others can easily tell you are not using a 35MHz channel.

There are some things to note more out of courtesy to other fliers than anything.

It makes sense to let everyone know which frequency you are using especially anyone else on the same frequency.
Most flights only last 10-15 minutes so have patience.
Normally you will only require the Frequency Peg for about 20 minutes or so. Please remember that if another member is on the same frequency as you, messing around with your engine or something that won't start for an hour or so can be very frustrating for the other member. Please let them have periodic use of the peg. If you are having problems, ask someone to help. They'll be pleased to do so!
"Hogging" a peg if other members require it is, at the very least, discourteous. We want everyone to enjoy themselves so please think of others.
Not following these simple steps will result in at least one model (probably yours) getting needlessly wrecked.
When you are ready to fly, you switch on the Transmitter followed by the Receiver (aircraft). On flight completion, the Receiver is switched off first followed by the Transmitter.
