RX repairs

[kevinh]

Has anyone had to send away receivers to be repaired?

Got two FP-R138DF which needs repairing.

send them back to Ripmax or is there anthor place which repairs them?

both need new aerials and 1 needs a new case

Hi mate

Try this place there spot on with work on radio's.

i doubt repairing a 138df is worthwhile. the schulze/hyperion rx's are better as they are DSP also a lot smaller. only around 45ukp.

i cant see an rx repair costing much less than that.

DIY -- Aerial replacement is a simple soldering job -- or find someone who can.

Whats the wire gauge any idea, no problems with soldering the wire

[Ade_Law]

Best to get the futaba type wire for your rx.Not just anything will do ?

There around £1 per aerial.

Speaking with my licensed radio amateur hat on - the antenna is simply a piece of wire cut to a known fraction of the wavelength of 35MHz (actually quite a small fraction since the wavelength of 35MHz is about 8.5m or so). A half wave antenna would be very efficient, but still 4.25m long - still totally impractical for a model heli Wire guage is completely irrelevant, although I'd use a copper stranded wire rather than aluminium, or single core stuff. If it really must be orange, buy the Futaba-marketed wire - or go to Maplins; they do a range of colours.

Cheers - Rob.

Are you sure orange is the best i thaught the pignemt in the plastic made into a semiconductor so it converted the

wire into coax and shelded it completly and thats what stopped it working.

Brown is best as it is by definition single core.....

[warboysastro]

umm...

Dielectric constant of various plastics could make a difference, but I would have thought PVC was PVC?

Ahhh but because its brown not orange it can be described quit e accuratly as being at one with itself an orange one is by the same inference not.... Surely a blue one with a purple stripe could be describesd as being all sixes and sevens......
