Hobbywing platnium 70HV Auto bailout

[salmonson63]

Just wondering if there is some sort of auto bailout feature with this esc. I can not find it anywhere. I do know that after 3 seconds of seeing no throttle the esc resets and goes back to soft start which is bad for a bailout because the head speed wont come back fast enough. Just wondering if people have found a way around this, or if you can still bailout with the soft start, or if I just have to wait for the gov to come out for the mini vbar and use the auto bailout feature on there.

Subscribed. Curious about this myself.

No only one esc to my knowledge has autobailout, cc. But combined mine with the vbar gov and i got autobailout on my 120 now

I doubt you will run into a problem with it seeing the soft-start on the HW's is actually pretty abrupt. It would probably be better that the SS kicks in since you are under 12S power which may strip gears if you hammered it that hard. The MOD1 gears will take a pretty serious beating but you never know. I've never really noticed a problem with how it is setup right now and if they fix the slow start they may have to make a provision for bail-outs.

My friend Ken has flipped out of TH numerous times, sometimes right towards the end of a botched auto and it has always ended well. I have been scared to, but he has no issues with it, so I'm sure if I were ever in trouble on an auto, I'd use it. It seems to spool up faster than the Super Soft start, but not so fast that it endangers the drive train. I may have a video of it, I'll post if I find it.

In my night flying vid from Bham you can see I hit the blades and tail on the ground towards the very end and hit throttle hold, and then spool back up in the air, and it was actually pretty similar to how the castle's sound in the air. I'm not sure about the 3 second quick spool thing that was mentioned as it was probably within 3 seconds of hitting TH, I'll have to try that sometime.

Like Cullen said, I've bailed out several times with the HW ESC but then again it's just a reflex reaction that I have after practicing auto's with my Trex500 (if it's not perfect, better try again). In fact, I remember the first time I bailed on the 6HV (reflex) and Cullen saw it, he thought for sure I was going to strip the main gear but it ended up spooling up just fine.....I'm pretty sure it was past the 3 seconds too as most of my auto's start up really high.

yes, don't know anything about a 3 second rule, thought it was "the 5 second rule".

thats only if it hits the ground and you plan on eating it!

I kinda want to try some power failure fake-outs like the pros are doing with bailout features... but I'd be scared if the spoolup isn't perfect timing and safe for the gear train. I haven't heard of this on the HW, interesting.

I don't think it's an issue with the geartrain of the Compass machines. I know that the Trex 700's suffer from gear stripping due to too much power (and I assume the same is true for the 600 class on 12S). Namely, they use really small gears which can't take a whole lot of individual loads. Tim Jones went through tons and tons of different gears with different shapes and sizes but ultimately had to govern down to more reasonable power levels to keep it from tearing itself apart. Not that Compass is impervious to damage, but the gears are a lot more resistant to that type of loading due to the MOD1 construction.

The Hobbywing works great for bailouts. The soft-start is not that soft but it is soft enough. The benefit of this is that when you hit throttle hold three seconds later soft-start resets. Now the not so soft-start works great for bail outs. Unless you wait till the last second of a botched auto it will spool up in plenty of time. Remember the head speed does not need to get back up to your full set head speed to start flying again.

[Gregor99]

What happens if you flip out of throttle hold before the 3 seconds elapse? When I first got my Knight I broke a tooth on the main gear. It was a while ago and don't remember what I did to cause it. But I think it might have been flipping out of throttle hold before the 3 seconds.

[salmonson63]

If you flip out of throttle hold before the 3 seconds then it will spool up in normal mode and no soft start will be applied. After 3 seconds it will reset the soft start.

It will want to go to full head speed instantly. If the head speed has not deteriorated to badly you will probably get away with it. Otherwise it could strip a gear

I have never stripped a gear on mine. I can't say I've counted the amount of time I've ever had it back to zero and thrown the switch, but I have had more than plenty times going back to full 100% from TH because of a bothced auto or other malady and niether ship has eaten a gear so far. I've done it a whole lot more on my 500 than my 6HV, but both have been subjscted to 100% throttle from pretty much 0 and have had no ill effects. That's not to say in the right condition it won't happen, but I do a pretty good job of torture testing my stuff through my own comings and goings of flying and everything has held up great on all my Compass machines.
