flytilbroke Posted February 18, 2012 Share Posted February 18, 2012 A very busy thread. I cannot give a true answer rhough, as some of my RX's don't have the function. On the ones that do I have the failsafe set on the 35Mhz types to hard over. The 2.4 Ghz Rx's I have not set any to a specific setting as yet, other than throttle cut.

Alwyn Gee Posted February 18, 2012 Share Posted February 18, 2012 That's the main one. Saves me having to keep one eye cocked to the North. It's not conducive to elegant flying as I need both eyes firmly fixed on my model. Alwyn Quote Link to comment Share on other sites More sharing options...

Swissflyer Posted February 21, 2012 Share Posted February 21, 2012 I fly mainly electric models of the “no built in stability” kind (no dihedral, nearly symmetrical aerofoils etc) That means I need an autopilot if the radio link goes down as there will be no graceful glide in However, I do make sure that if the transmitter is switched off, the esc turns the motor off & servos are neutral. The idea is to keep any dramatic end within the flying field! I also stick with “wind safe” i.e. try to keep the model up wind so that any incidents stay in sight & in range. Of course this is a long way of saying “take all precautions possible to keep mishaps on the flying field”. Fail safe is one of them but I think modeller’s common sense & good safety habits are the keys to safety from failures Happy flying Mark Quote Link to comment Share on other sites More sharing options...
Tom T Posted February 21, 2012 Share Posted February 21, 2012 on a serious note what is Failsafe.....? I will probably know if it was described Quote Link to comment Share on other sites More sharing options...

Swissflyer Posted February 22, 2012 Share Posted February 22, 2012 "on a serious note what is Failsafe.....?" Google suggested http://http://rcvehicles.about.com/od/glossary/g/failsafe.htm Hope that helps Mark Quote Link to comment Share on other sites More sharing options...
Ian Jones Posted February 22, 2012 Share Posted February 22, 2012 I think Swiss Flyer meant this However I would refer to the BMFA handbook as I think that is more apropraite to aircraft. (Available here - page 29 and 30) Note the newish paragraph for electric aircraft.

Swissflyer Posted February 23, 2012 Share Posted February 23, 2012 Sorry for the typo, you are right, I did mean that, thanks I seem to have spent more time with 35mph electric cars than aeroplanes recently. We discovered that "end of run" low battery voltage was leading to a glitchy steering servo and a car that wanted to throw itself against a concrete wall at 35mph. Yes, cars are about split seconds; give me some altitude & a few seconds more to play with Mark Quote Link to comment Share on other sites More sharing options...

daddycool Posted January 28, 2013 Share Posted January 28, 2013 Hi all At my club its compulsery to use failsafe, dueto the fact that we are almost yards from an airfield, it at least stops an aerplane from going for miles if there is a signal failure and however the co ntrols are set I suppose the idea is to get the model down safely and as quick as is possible. as far as legallity is concerned be it true or not it is in the interests of modellors and keeping our sites to use it.

SkippyUK Posted January 28, 2013 Share Posted January 28, 2013 Some of the Spektrum and/or compatible RX's I use have failsafe and some don't. I always re-bind the RX after all settings been done on a model and then re-bind again after maiden flight after setting a degree or two of rudder to hopefully induce a slow gracefull circle. I've lost signal a few times over the years and the above gives me a chance to reconnect before the mid-air with terra firma occurs.

crispin church Posted January 28, 2013 Share Posted January 28, 2013 i always set fail safe but cant say fly aways my reason for it just got too many scars from props and broken fingers well normaly same finger but never same place Quote Link to comment Share on other sites More sharing options...
Myron Beaumont Posted January 28, 2013 Share Posted January 28, 2013 Failsafe Hmmm No such thing in my opinion -nothing is !.I think I have it on my gear ,but I also trust myself not to rely on a "failsafe device" when I'm capable of flying within my battery capacity limitations whether they are are electric or ic powered A/C . I do use a multimeter as one of my best accident preventative tools and has worked for me since day one .I suppose soon we.ll have a gizzmo to tell you whether the failsafe mechanism is working or not -Ad Infinitum!

Myron Beaumont Posted January 28, 2013 Share Posted January 28, 2013 Simon Boom boom ! Nice one BUT I have never wanted to try that nor have I ever needed to By the way ,my Futaba 6EX hasn't even got a built in timer which if it had might fail as well .I wear a 60 yr old Longines watch .Now,I trust that !!

Chuck Plains Posted March 8, 2013 Share Posted March 8, 2013 As we fly over National Trust land with the world and his dog walking through, we have to set failsafe on every model. Quote Link to comment Share on other sites More sharing options...
Simon Chambers Posted March 8, 2013 Share Posted March 8, 2013 Myron - sorry I missed your response! Its perfectly safe to do so on 2.4GHz or in fact any receiver with failsafe. In fact its recommended for the exact reason that you should test it is set up correctly. If you suffer signal loss, it'll be the same as the transmitter being turned off. Si.

Bob H Posted March 9, 2013 Share Posted March 9, 2013 No need when flying electric. What happens if you lose your plane for a while in the ground ? ( with the failsafe set) Your motor will keep running until the battery is flat and you would probably require a new motor after . The prop will just keep on turning digging a hole.

I don't follow, that sounds like an argument FOR fail-safe. I certainly don't want the motor running if the model's out of control. Quote Link to comment Share on other sites More sharing options...
