Great Job!!! I think it is awesome and at the field with a little more space between the new pilot and the heli I dont see how it is any more dangerous then a lipo. Worst case it goes the 20 feet or so and unpluges or crashes, so stand farther away then the cord can reach. If it had a lipo and was out of controll it will go where it wants with no limits until it hits the ground, at least with the cord it give you an imaginary 20 ft bubble to keep it in check. I think most people say it is a bad idea because it is not how it was designed or it is not normal opperation but what would this world be if nobody ever thought outside the box? I like the idea for learning and I think your friend will have a blast flying for hours instead of minutes after all that is what this hobby is all about, flying right!!!and the blonde said "RECTUM, Hell damn near killed em!!"

John I've been waiting all day for you to post that.

Bloody good idea.
First thing Monday I'm going to buy a pair of batteries and 300, OOPS, 30 feet of cable.

Well done mate!

Cheers,

Chris

Thanks jack and flyride for your positive comments.
It's very windy here in the uk at the moment,as you could probably tell in the video.
I hope tomorrow the wind will die down,if it does I will add another 25 feet to the setup,so the total will be approx 35 feet and go down to the field and take some video with us standing at a comfortable 50 feet away.
I'm going to add some bungie cord to the last 10 feet so I will be able to tell when were close to the end of the cable as my eyes will be looking thirty feet up,and I should feel the resisdance through the sticks.
Because it was windy we went on a bit of a mission,and spoke to some guy at the local disabled scooter shop and he said he could sell us some used but good batteries for next to nothing out of the scooters that come in for servicing,he said there all good but get changed out as a matter off coarse,so i am going to make up a smaller system that will only give you 4 hours of continuos flying
Mikes done at least 6 hours now on the first setup and alls good with the motor esc.
It's gonna be funny tomorrow when we go down the club,I bet we get some strange looks

Thanks
John

Now that's another bloody good idea, we call them "Gophers" down under. They'd be sealed deep cycle batteries I reckon, better still. Golf carts use them as well don't they?

I'm already checking out the yellow pages for leads.
You've had a few looks on youtube, I was the second and she was up to 30 about half hour ago, not much comment on here but.

Cheers mate,
Chris

Again all looks very good to me I think you have clearly demonstrated that this idea works very well,sure it might not be everyone's idea of what's suitable or not but as far as I am concerned it's effective,safe and ideal for hover training.

Please keep us up to speed on how you develop it.

This reminds me of the time when I hooked my Trex 450 up directly to a 12V power supply. I did this about 5 years ago.  ▲
