WOW. Total loss, then. TRULY sorry.
Man, my heart really goes out to you. Must have been hard to witness all of that being so close to the unfortunate action. No need for any comments from me, buddy. You've already well assessed the situation and come up with your own conclusions yourself.
All I want to add is don't take it too hard. Accidents DO happen, that is for sure, regardless of how many hours one may have in the air. It's part of the nature of the beast all of us embrace once we become drone pilots with more than a $1,000 of ours hanging in the sky.
But you are taking this misfortune like a true trooper, my friend. Way to go and thumbs going way up to you for having accepted it, owning the blame, and already ordering another one to replace the downed machine. Getting back up on that horse ASAP is the BEST thing you could do in the face of what you are dealing with. Your reaction is commendable. Just tell me where to send flowers as I can't possibly make your Typhoon H's funeral, but my thoughts will be with you as you take it to its final resting place!
P.S. Don't forget to salvage any parts you can from your wreckage. Gimbal plates, shock absorbers, mounts and assemblies, and more may still be in good shape, maybe even some landing gear or arms with rotors survived intact, who knows? Consider the logic boards and other electronics tucked safely inside the Typhoons strong body frame, too. Just don't be in too big a hurry to just toss everything out, as there may be some very worthwhile parts that you could use in the future in the event of another a crash or accident. You will need a toolset specifically designed for drones - readily available - to undo the screws proprietary to drones, but with those salvaged parts in your possession your only other costs to making any future repairs would just be either your time or hired labor, as you may have the salvaged parts on hand to save you some bucks in the parts department. The Typhoon's modular design makes disconnecting modules a relatively easy chore to do. (There are YouTube videos available that explain exactly how to entirely disassemble your Typhoon H.) Don't throw out the baby with the bathwater. Maybe it is a total loss, but then again maybe not.
