Thank you both for your great replies.
It does hit the boot but doesn't stick.Not sure what you mean .
- The rod from the servo goes through a hole which incorporates rubber bellows - boot.
I have been puzzling about this for some time as ever since I got into this hobby it has been nothing but trouble and I was about to get my hat and make an exit, if it wasn't for the friends I have made on the forum, I would have done just that.
Great, I now have a reason for the behaviour of the boat.
The failsafe was not set, nor were the servo endpoints.
From what I can gather a number of people run this boat custom and no mention has really been made of endpoints so I thought it would be ok to run without setting them.
Fact is I have now had at least 2 crashes that have resulted in a sunken boat, some dangerous and disgusting swims to retrieve them followed by hours of epoxy and glass work only for it to happen again.
back to the topic at hand.
On this occasion it was the didgital servo and it only took 3 minutes for things to begin going wrong and I now completely accept that the draw from a digital servo that stalls or can;t track to its endpoint has resulted in the BEC going down on the ESC and hence the out of control crash.
I've run with 2065 traxxas before which have lasted alot longer however on one or two occasions the boat suffered a simillar fate only those times the servo's seemed to work afterwards leaving me stumped.
2 of these have now failed completely but do not heat up or cause the ESC to heat up. They simply dont function. The Rx signal LED is fine the throttle works but the servo just doesnt. I thought initially that the Tx
had stopped functioning only to find that a new Tx Rx pair behaved in the same manner eliminating the Tx and Rx.
So my next question is.....could the load drawn by the analogue 2065's have caused my previous crashes and all my issues stem from not having set up both the failsafe and the endpoints ? In addition to the failed servo's I have 2 puffed 2200 40C turningys that puffed only after 4 cycles / runs lending credance to this theory. Its funny though, the nano techs I had before seemed to last alot longer.
I had it on good accord that the earlier crashes were more likely to be due to using 2.4ghz flysky on the water....jamming the signal from spray / wave reflections.
My gut feeling it its more likely the servo's as I now have 3 failed ones.
Whats is your opinion please ?
Regarding wattmeters etc. The hull I use is micro hydro and as such there is no space for meters. I can only measure draw on the bench with a conventional fluke multimeter. But I have not one so as yet.
Many many thanks to you. Your help is invaluble.
