These 2.4 thingymajigs

[co-pilot (no longer)]

Hi all,

 

I have just entered the 21st century and bought one of these futaba 2.4 receiver and transmitter things.

 

My question is how do i install the receiver in terms of the aerial wire placement.

 

I am used to 35mhz and running a long wire down the fuselage and out of a hole,Then securing it at the tail.This receiver has two short wires.

 

What do i do with them?

 

Thanks

Place them wherever convenient in the fuselage at a 90 degree orientation to each other I usually just tape them to a with a small piece of gaffer tape

HI Ben,

The instructions with Futaba are pretty clear. But, sometimes, its difficult to achieve the angles suggested between the two aerials, especially in small, narrow fuselages.

 

For my last model, an electric glider, I cut a hole each side of the fuz, and let the short lengths hang out. This way, they are well away from moving metal push rods etc; 

 

Finally, I understand this is highly recommended (essential) for carbon fibre models

so do they have to exit the plane or is it ok for the wires to be taped up inside the fuse?

The instructions that came with it were rubbish.Just says dont wrap in foam etc.Absolutely no mention of how to install it

If the fuz is constructed of non-conducting material (eg. wood, glass-fibre etc.) then the aerials can be inside.  Just do your best to keep the wire end parts at 90 degrees to each other. 

 

If it's made of carbon (or less likely, metal!) then the aerials do need to be outside the fuz - and best to be on opposite sides to reduce the chance of both aerials being masked by the fuz from the transmitter.

Hi Ben, It really is very simple

1   I fix the reciever at a convenient  place with sticky back velcro.

2   I drill two small holes, one each side of the fuselage

3   I thread the two small aerials, one each side, and let them hang out in the breeze

If possible have the wires at 90 degrees to each other so they are better able to cope with different orientations of the model with respect to the tx aerial.
