Default RE: Why should I use a PCM receiver

Can't say I blame you being upset with losing an aircraft like that.

Great news about the RS10DS from the distributor, they are a very nice unit, I have two currently in service, both in pattern planes. I love the synthesised feature and they have excellent range. The only issue I have had with them is an intermittent problem with (you guessed it) the Rx going into failsafe in one particular circumstance, I have only seen this happen in one of my RS10DS Rx. This has only occured on the ground, in the air the Rx has been rock solid.

Failsafe occurs intermittently when the Tx aerial is fully extended and running parallel to the Rx aerial within about 1 metre. For me I do this at every take off because my habit is to run up my engine (clear its throat) by standing in front of the tailplane just before I take off, I experience the problem about 10% of the time in this position. It is intermittent so it isn't something that I can replicate on demand - irritating when you are trying to show someone else the problem. I heard that Chris Callow (Pylon World Champion) had experienced the same problem and I called him up. I got his Dad (Kevin) on the phone and it turns out he did have the problem and his advice is that it occurs because the Rx gets swamped when the Tx is really close (<2 metres) and that it doesn't occur further away so there is no issue when flying. He also told me that Chris now wont use this Rx and has switched to the JR R900 (PCM non-synth, single conversion) because he flies so fast/close and can't afford for interference/failsafe condiiton to occur.

So I must say I am smiling as I write this given the views I expressed in earlier posts! But I thought you ought to know.

These are the facts as best I know them about the RS10DS, if anyone knows anything else I would love to hear it.
