Belvedere Tower, Claremont. Surrey, UK - TAKE 2! (plus my first autorotation!!)
Hi all

As the weather was glorious today, I decided to go APing for the second day in a row

I went back to my old school to get some more photos of the Belvedere Tower. You may remember I took some photos of this building at the beginning of January but it was overcast. Well today the sun was out, there were very few clouds in the sky, and there was no wind! Perfect!

Out of the 118 shots I took, these are my favourite:

I also took a panorama of the Mansion in front of the Belvedere, with its view down onto the playing fields of the school:

Unfortunately whilst shooting the last Belvedere image above, for no reason the motor cut out on the helicopter!! I'd only ever done autorotations (where you use the downward motion of the helicopter to speed up the rotor blades such that when you reach ground level, the rotors are still spinning fast enough for you to land gently) before on a simulator as I was too afraid to try it for real, *just* in case I didn't do it correctly! Well that simulator practice paid off, as I managed to get it down safely in a pretty confined space!

This photo shows roughly where the helicopter was when the motor cut, and where I managed to land it ....

It wasn't *quite* as tight as it looks as it landed a few metres behind that bush on the left .... still, I couldn't believe I managed to do it!!!

Even though I had two more flight packs and the helicopter seemed undamaged (even though it landed with a bit of a bump), I decided to call it a day! I'd got the shots I wanted anyway

Until next time

David

Hey Bullseye

Thanks for your kind words

Regarding what caused the motor to quit, no I'm completely baffled! There are a few possible options though:

1) Failsafe ... the throttle channel *is* set to 0%, so maybe that could have been the cause if there was a sudden burst of interference for some reason ... oh, and I instinctively hit throttle hold as soon as the motor quit so I'm not sure whether it would have restarted after a short time ... I guess that's a side-product of practicing on the sim where I instinctively hit throttle hold if I want to do an auto

2) ESC overheating? Hmmm unlikely as it was only warm to the touch on landing, and I'd only been flying for 5 minutes ... and I can get about 12 minutes flight time per pack.

3) Battery failure ... hmm, the battery was in good health when I last charged it, it was still registering around 31v (it's an 8s pack), and when I put it on charge at home, none of the cells had a significantly different voltage ...

I'm guessing it might be interference of some kind ... I only recently set up the fail-safe to drop the throttle to 0% ... maybe I should remove the F/S from the throttle channel? ... but then what happens if my Tx packs up! Hmmm ...

Not sure what else it could have been!

Thanks for all your kind comments guys!

From the short time I had to perform the auto, I could tell that auto'ing with this heli won't be too much of an issue .... When I first heard the motor cut, it was a short time before I realised and also I fumbled a bit with the collective on the way down, and even then there was enough headspeed to make the heli bob up pretty high when I gave +ve collective to slow the helicopter's descent.

Good job I've had experience of this now as I had two phone calls out of the blue today requesting some AP work!

Cheers,

David

Nice shots and GREAT save, David!!!

You accomplished more than is usually expected in a bad situation:

1. Safely auto without harming anyone
2. Same as above without damaging someone else's property
3. Same as above without damaging your own equipment

You got a little lucky I'm sure, but excellent work. Sim practice is absolutely invaluable and obviously paid off for you

Congrats
