If HV is an issue just use a LiFe pack and call it good. Personally, I wouldn't bother with a backup solution like the UltraGuard on a heli running an rx pack.
Backup solutions are a must for electric helis. With the exception of forgetting to charge your rx pack, when was the last time you heard of one failing?
Just finished about $500 in repairs to my NX7 because the frame cut the battery strap and the pack came unplugged. A $45 Ultraguard would have saved it and will be on the Heli when it flies again. A backup is always a good idea.

A good preflight would have prevented it as well
what if the frame cuts a wire

Yeah, obviously. Leaving it on the shelf would have also saved it, but I fly my stuff and recognize that things get missed at times, even on your helis. Still doesn't negate the point that a backup would have avoided the rebuild.Nick Crego

Then you have a building issue.

Neither changes the fact that things happen, and redundancy saves you when they do.

Look, YOU may be perfect and catch everything on preflight/building and never have a crash like that. Congrats if that is you, spend some more time in the hobby (or really life in general) and something will come loose, break, cell will fail, etc. It's not going to happen often if you are thorough, but something WILL happen. Do everything you can to avoid it and maybe you'll be lucky and it won't result in a rebuild.

After flying helis for 22 years, I'm good at spotting things before they go bad. I'm a good builder. I'm very thorough at setup, tuning, and preflight. I've crashed for pretty much every reason imaginable over the years and have made every mistake and tried to learn from them. I shared what happened to me, maybe it'll help someone else avoid a problem. No one is perfect, and if you have enough hubris to criticize me missing something and crashing from it, then odds are you lack the ability to learn from the mistakes of others and will end up repeating them. However, I'd bet most people are like me and after reading how I missed something and paid dearly for it, will check their own helis.

My experience has taught me that no matter what you do. They will eventually crash.
Although I have yet to experience a mechanical failure since I ditched Century years ago.

Look you can spend all you want on back ups and I can guarantee it will still crash eventually.

I'd rather buy quality gear and do thorough pre-flights and post flights at home on the bench.

you should have bought a 50$ battery strap that's cut resistant or sand the frame edges smooth.

As for years of experience I have seen trades people with years of experience overlook stuff out of complacency or what ever reason.
Even a guy with 50 years experience can still make mistakes.

ya you got a few years on me, I have only been in the hobby since 2006.

But when I hear Blah blah blah 20 yrs experience. I know it's more about ego than intelligence.

Stuff happens man. You don't have "build issue" You had an accident. That kind of stuff happens. You are now aware of it and can fix the issue. But to say it's a build issue isn't right.

Better flying days ahead my friend.

OK ok buy a back up gizmo if it helps, it took awhile before I could trust these crazy RC machines, That like to hurt you, When you don't pay attention.
I respect my stuff as though it were a weapon. just the right amount of paranoia to keep me alert.

Please don't think I'm blaming the cut battery strap on the persons ability stuff happens. Ya if he had the back up battery thing It would have save it this time, But the next time it might be a servo. Do you have a back up servo ?
Or a back up link or how about a back up jesus bolt.
I wish my nitro had a back up starter for those flame outs
