Contaminated motors

I think the idea is to keep that “catcher thing” on permanently and grab the handle when the AC is landing.

Ahhh that makes much more sense, thank you.

Flat palm, like feeding a horse!

A chainmail glove, like what some butchers use! ?

Or just get one of these ? ? ?

Hand catching is for the young pilots do it. But its still dangerous, especially for a newbie that has never done it before. Would be interesting to know how many seniors above the age of 70 hand catch a drone?

When taking off from coastal areas, near a beach for instance is there any way of preventing/removing grains of sand from the motor housing also would it be possible for a few grains of sand or soil to damage the motor? Thank you very much.

Unfortunately there is salt in the air as well and this coats everything, including motor winding and circuit boards etc.
This can't be removed by compressed air, so it's probably a wasted effort to try and clean motors, just rely on the conformal coatings to protect sensitive electronics.
Also there is air pollution that will coat and stick to everything internal as well

@old man mavic does and he's a hundred and eleven

I do the same with a 1 ft weighted cord (1/2 oz sinker) and my GetterBack tied to the end. Something to hand grab and a way to salvage a water crash for Care Refresh.

yeh right ,i feel that old some days,unfortunately i cant even contemplate such a thing as hand catch ,because i take a anticoagulant ,every day for my heart issue ,i cant afford to get cut as i bleed profusely and cant take the risk,besides i prefer the fun of trying to land on my home made landing pad if the wind gets up, its a great way to hone my stick control

Have Mavic Pro. Downward sensors turned off permanently. Like flying over water etc. Always hand catch.
Its no problem, bring drone back facing away from you just above shoulder height, reach up under to hold body, then power off.
The drone will just hover in place giving you plenty of time to adjust to reach up under the body. well away from the props. Never had a problem and feel quite competent even though I am an old fart with Multiple Sclerosis, and history of seizures.
Over next few days will try to get a mate to take a few shots of me hand catching. It isn't that complicated.
Honestly my co-ordination is not good but I have MS, Seizures and Cardio Myopathy. Will be 68 in July. Never had a close shave. Lol

Salt can be removed from motors by gently dipping them into warm fresh water, then quickly drying them with a leaf blower or canned air. I did it many times with no long-term ill effects. I agree that if a drone is used near water most of the time, silicone-based conformal coating on most electronics except camera, VPS and barometer is the way to go.

And I beg to differ about "wasted effort". Salt on motors is not nearly as destructive as stuck particles of silica or magnetite.

Yes your right, particles on the motor windings have an impact
I do give everything a blow with my X3 hurricane blower for the larger particles, but the salt coating on exposed wiring and connectors is not removable without using some sort of circuit board cleaner

I know it's off-topic, but here's my blower. Completely home-made, including CF prop and aluminum duct. Packs a punch at 60000 RPM, using motor from my late pylon racer RC plane

You should sell them

This thing is seriously dangerous (enough to sue the heck out of me). Besides, making a prop that could withstand such RPM was a nightmare. Several earlier versions blew up spectacularly.

The fact you might have performed this rinsing procedure many times without ill effects doesn’t mean it was necessary. It seems to make little difference how thorough a wash you give the underside of vehicles driven on the beach close to the tide mark and how often you do it they still rust.

I live in the ocean and fly over and near salt water most of the time. The worst issue I have had is some obvious corrosion in aluminium components. No rinsing performed.

I didn't say it was necessary. I merely suggested how it can be done.

You are a LI resident, correct? We are neighbors. I also fly over water pretty often. I don't like discoloration and grey powdery residue on my motors, aesthetically, that's why I rinse. If you don't care about such things, there's certainly no need.

I do. Before the first time I watched a few video’s on YouTube on how to do it and (also in practice) with a little bit of care it’s a piece of cake (with a M2P). You don’t have to take a landing pad with you and you don’t have to clean it each time after use. Besides, as mentioned before, a landing pad is not an ideal solution for sandy surfaces.
