I fuggin' love Amazon reviews sometimes...

In flight trim with minimal battery, the drone weighs about 4kg and can lift another 4kg; it's good for about 15 minutes flight time at that payload. It's a slow drone; top speed is about 15mph. Using my l33t math skills, that's a range of about 4 miles. Assuming a 2-way mission - so an outbound range of 2 miles - results in a potential coverage along a straight section of border of 6.283 square miles. Increasing the range to 4 miles (via suicide mission or different hardware) grows the possible target area to more than 25 square miles.

Even my cheesy Mavic Air can be programmed to fly waypoints instead of being flown manually. There are loads of flight control apps that support full autonomous flight, including remote landing. None of this is sci-fi - it's all off-the-shelf stuff you can buy at walmart.com...

Understeer: You will hit the wall with the front end.
Oversteer: You will hit the wall with the rear end.
Horsepower: How hard you will hit the wall.
Torque: How far you will move the wall.

Gone hunting with Alec Baldwin and Dick Cheney. Back soon.

I joined the club. Bought me the Contixo F22 drone and WLToys V950 helicopter.

Looking forward to trying out the helicopter the most.

I've been hankering for a helo for a while - but I don't have Alishanmo's skillset:


RC helicopters have come a damn long way since I was a kid.

I would reduce that thing to rubble in the first flight. How's yours working out / how long until you get to try it out?

All fun and games until you cut someone's head off!

For the record, I've wanted a heli since I was a kid. Just never seemed to have gotten around to it.

Fedex says it should get delivered tomorrow. So will probably try flying it on Saturday or Sunday.

This occurred back in the early 80's so I'm sure they are different, but...I had a buddy who raced RC 1/8 scale nitro cars with me and he had flown fixed wing RC airplanes with his dad since he was about 5 years old. He was the best scale pilot I had ever seen...he was good and I got stories of how good. Along came helicopters, he bought one with the "learn to fly" tether stand. He fought that thing for weeks and keep in mind the control box was like an extension of his hands-brain. Did I mention this guy could fly RC? He did get the hang of it, flew it for a while and reported he didn't like it because it was too stressful. Today I hear he only flies scale jets and...wait for it... helicopters! So hopefully there are some built in nannies for helicopters these days because back in the day if Donnie struggled with one it was a bitch!

Good Luck!

My dad took me to a park to watch a local club fly and they had a "that guy".

Most still had hoola hoops attached to the skids to help with landings as they learned. Not this guy though. First time flying it, lifts off, does some nice flying, and promptly destroys it while trying to land.

When I looked it up later in my Tower Hobbies catalog it turned out to be a $4k (in 80s dollars) setup :o

I think that is the root of why I've never gotten into it ;)

Story on Donnie. Another friend wanted to learn to fly so Donnie took him out with a bi-plane because "it is easy to fly". They were both on the flight line. Donnie took it off, climbed out, leveled off and handed the controls to the rookie who promptly set it into a spin. Donnie took the controller back leveled it, climbed, leveled off and handled over the controller. Same thing happened...three times. The fourth time the top wing tore completely off! This put the plane into a hard spin Donnie grabbed the controller went to full throttle, yelled at his Dad to shut the F up because he was flipping the F out. He brought the plane down, approached the air strip and landed the plane without drama still at full throttle. I thought it was done well, but the complete silence from all the old guy flyers behind the flight line told the real story. They were absolutely speechless! The guy can fly an RC plane.
