Doesn't really matter who has the highest, not a contest. It's a matter of what they report the problem to be. That qualifies spektrum and xps. So far, I don't believe futaba has reported voltage being a problem. They probably wont due to them having a failsafe setting for battery voltage...

None of this is a contest. Just specs about each system. Futaba may not have reports because it was out way after all the battery issues and now its more common knowledge from everyone freaking out online about it. Do you know how long the system is in failsafe when the low cutoff is hit? If its long enough you may crash anyways. Voltage is an issue on all 3 systems. But Spektrum so far has the worst voltage issue. Something electric fliers might like to know before they purchase a system. I know you now hate XPS but try to look at the specs and be objective. We are trying to educate people (at least that is what Xjet set out to do, right?) about the pros and cons of each system. If I were FASST I'd say my pro is the lowest cutoff voltage. But it still has one, doesn't matter if the RX goes failsafe or goes crazy or shut downs....you still have no control of your aircraft. So its a con.....but a pro over the other 2.

I'm being fair!! You lumped that onto spektrum and not xps when xps claims that it's a problem as well... Seems it's the same for both.. I definitely am influenced by what has personally happened!!!! & with jd's exaggerations well.... But still, fair is fair!!

[quote=sweetpea;365412]I don't think Spektrum changed their cutoff voltage( I need to research that), only once it does cutoff the system looks for the last 2 channels and the reboot time has decreased. So that is more inline with the other two. Voltage is an issue on all 3 systems. But Spektrum so far has the worst voltage issue. Something electric fliers might like to know before they purchase a system. I have heard this over n over -- but in actual practice don't see it and I have a LOT of electric setups 6100/6100E /6200/7000rx and with quite a variety of ESC/ battery (LiPo and A123 ) power setups I will say - Spektrum being first on the scene got the brunt of the learning curve (some have never learned tho) so natcherly they got the "the sky is falling" comments--- over n over n over Having seen other brands of 2.4 operate - it appears to me - if you do it all correctly - the results are the same Because Spektrum still is the only one haveing itsy bitsy rx - they will -(bet money) continue to be the leader in small electrics. I simply can not get any of my electrics to fail --- |

Spektrum has the worst cutoff voltage...period. That was the point of including it in spektrums problems and not the others. I was trying to make the point if you put the systems in the same plane with same gear.....what would fail or be better for each. I don't care why you cannot understand that was the reason for not including it. So XPS says this the number one problem with their system. I'm not saying what is #1 or not only that it would show up in Spektrum first so if voltage is your concern you should chose a better powersupply system or a different 2.4 I already said I would take the voltage part and adjust it to include voltage cutoff amounts as a con for all the systems. I think the issue you are having is XPS told you your crash was voltage related and you don't agree with them. If I am correct, that has nothing to do with what I'm trying to accomplish. So drop it. If not I apologize ahead of time.

Your lack of wanting to list xps with a low voltage problem indicates a bias toward them as well... If not, then I apologize in advance ![]() I was told voltage, I was told servos, I was told battery short, I was told failsafe.... Everything but what it appears to be... Lack of freq hopping when an outside source interfered... | ||||||||||||||||||

It is also what has been reported by the owners of crashed R/C airplanes and helis independently of what XPS suggests. One has only to view the forum over on RCG to see this. I would also go out on a limb and state that the MAJORITY of crash reports on the RCG XPS forum ended up being actual voltage delivery issues, independent of any RX faults. In other words, other than in your jet, when XPS suggested a possible voltage delivery problem, the owner DID forensically CONFIRM a voltage problem that was NOT an XPS failure. | ||||||||||||||||||
