Calibrations

[Mrgs1]

Thanks so much guys for your valuable advice!
Hopefully I'll get it done tomorrow.
Actually after flying the new bird twice, i did notice it almost hesitating to land, not just slowing landing automatically as it does but actually almost not wanting to at all.
Guessing this could be due to calibrations?

if your UK based, it isn't looking good tomorrow. Monday looks better

Yea, unfortunately I'm in the British isles, probably the worst for weather, the isle of man, we sure get battered here!
Not to mention the difficulty and expenses in getting stuff!
Ah well, the times will come...

Heck of an opportunity with the Isle of Man motorcycle races.

Good things come to those who wait as they say.

Would like to see follow me!

Unfortunately not, complete no drone law here during tt

The reduction in descent speed close to the ground is not initiated by system programming, but by a condition called “ground effect” where the column of air under the aircraft becomes compressed by the spinning rotor discs. Although the air is roiled by the props there is still a compression effect.

At high descent speed we can blow though that compression layer and have the gear impact the ground hard enough to cause the aircraft to bounce back up, a common occurrence when using Home mode for an automated landing. If we are not prepared for that we encounter the possibility of quickly applying large control inputs only a couple inches from the ground, and if those inputs were too large or incorrect for the condition the next ground arrival could end up a roll over.

Turtle mode is where the close to the ground descent speed reduction is most evident. If you are new to the H, used to systems with more sedate landing characteristics, or without lots of previous RC aircraft history it might benefit to initially descend in Rabbit but switch to Turtle about 10’ above the ground. Be advised that both descent speed and control response is reduced in Turtle mode. Although slower in response and speed it will allow the new flyer more time to plan control inputs for changing conditions.

A reason not to descend from high altitude in Turtle mode is because the descent speed in Turtle is extremely slow. If battery voltage was low at the start of a descent it’s possible to run out of battery before reaching the ground in Turtle.

Always seems a sense of satisfaction landing her manually.

Ive only flown in angle mode and rabbit, don't wanna rely on auto shite, rather be the pilot and get it right.

Even if allowed an H could never keep up. Those bikes are doing well over 100mph. Prolly closer to 200mph on the long straights.

One more question, sorry if this has been answered elsewhere, can i perform these calibrations on storage charged batteries? Would rather not fully charge one only to do brief calibrations then need to discharge as the weather here is currently not suitable (again ) for flying this weekend (high winds).

One should be able to perform all calibrations using a 50% (charged) battery. The power drain is not much until the motors are running and in flight. The 14-15 minute gps almanac update time doesn’t take much juice either.

Once calibrations, updates, et al are complete, easy enough the charge UP to storage levels, given a capable charger.

I use [my] worthless PowerExtra batteries mostly for calibrations and short check flights. They don’t last very long in regular use. (This is my experience with these particular batteries. Others have posted more favorable experiences.)

weather was good down south today, was it good for you did you get your calibrations done ??

Unfortunately not, I'm on the Isle of Man, almost always windy here! Thanks for asking tho, I'll do them soon enough hopefully

Yea, would probably have to fly higher than the 300 feet to be able to follow them on a short stretch with the camera tilt but with helicopters around flying low filming it already it would be asking for double trouble!

I meant it as a joke, but on the slow bits corners etc, probably string a few drones in a line to follow the action, but you said its prohibited, then helicopter then!

All the Scots blowing the wind down to you.
