Being a beginner still myself I would advise against this and put him on a sim for a while as well as the normal packs + maybe training wheels.

It might be just me, but my first few hovers it was a rush and after about 5-6min I was ready for a break. During the break I'd think about everything that was going on during my hover like heli movements, my corrections, etc.

It might be a bit slower to learn that way but slow and steady in my opinion.

Though I must agree that it'd be a cool thing to see as long as it's donw very safely. LOL.
I love my flying lawn mowers!

It works
Ahhhahaha,it works.
He has been flying for 10 minuteson,then a ten minute break,then ten minutes back on again and it works.
We have put training legs on with the power cable zip tied to the legs,the cable trails off with intermittent nuts every foot as weights to keep the first 10 feet cable tight.
Three 2 hour sessions and he's hovering 6 foot off the ground with confidence,now that's quick.
I'm going to put him on the only 6s pack I have tomorrow to get him a bit higher.
Continually charging that 6s pack would of taken two weeks of on and off flying,as and when I had time/could be bothered,we've done it in a day.
I'll have to shot a video to post on YouTube,I wonder why no one else has thought of this,and throughout the process it was no more dangerous than flying with a lipo pack,is all we had was a wire dangling below the heli.
Watch this space all you wannabe heli pilots that can't get anyone at the field to give you a chance on the buddy box,or don't have a club close to you.
Video to follow at the weekend.

Why not drive into a field, hook a cable upto your car battery and fly a 450 in the same way! You could even have the engine running if your 450 is geared up for 4s!60% of the time, it works every time!

Update on hover battery
One thing we have noticed is that the e550 heli we are running the now 2 x car batteries in series on(truck batterie was old and tired),gives the heli some awesome power,it's like nothing I have experienced with any heli,electric,gas, or nitro,there a presence of power in the heli,like it would chop a tree in half if it came near it.
Because of the intense power I've dropped the head speed in half as it feels like it's on steroids,and it still has plenty on lift at half head speed.
I run my own business and am working long hours, but will do a video at the weekend.
Once you see the video,I think you'll all agree that it's a fast track way to mastering the hover,and to add to this someone that is starting out dosn't have to spend a penny on lipos,as in the uk a 6s thunder power 5000mah is approx £250(420 dollars).
I don't know about other parts of the world,but here in the uk,a lot of rc flying clubs are very stuffy.
Example:
when I first wanted to learn to fly helis 12 years ago,I used to go to the flying site every weekend with promises of someone taking me on a buddy box,only to find they had,either been up earlier than arranged and gone home/where flying that day and couldn't be bothered/wind was to strong/didn't turn up/amongst many other excuses,which after many frustrating months I gave it in.
A year passed and I thought I'd give it another go and taught myself to fly helis,and have never looked back since, and have hundreds of flights behind me.
For a newbie who has no club in there area or no one to teach/be bothered with them these are the benefits.
1/no nitro engine/ tuning to worry about whist learning
2/no lipos to buy until you have mastered the hover.
3/you can do as much uninterrupted flying as you like without waiting for charging lipos.

Example:trex 450 with a 12 volt car battery rated at 120amps will give you approx 6.6 hours of flying
120amp divided by say 3000ma 3s lipo =40 x 10 min flights divided by 6= 6.6hours
Trex 600 2 x car batteries in series.
And to say it's dangerous is a bit of an exaggeration.
I have been with my mate whilst he has been using the setup and at no time has it seemed dangerous at all,I almost feel jealous that he's flown solid/learnt the hover in just two days

John

Hey don't know if anyone has told you didn't read through the whole thing but be sure to have a lipo in the battery holder as to keep the COG where it should be. If not she will be too tail heavy...

Should work even better if you add a bungee cord so the heli never reaches the end of its leash when his skills improve and he starts testing some aggressive climbouts.

Looking forward to the video!

Look forward to seeing the video,sounds like a pretty good idea to me,as long as you have ensured the cable is long enough,not too heavy etc and the heli is kept within limits of the cables reach which you obviously did seeing as its proved sucessful.

Good job

Video
Thanks raptor50lover
I will be doing the video tomorrow,Saturday,which is twelve hours from now,for all those across the pond.
When you see the video,I think most are gonna say what the f***,as this is so right and so simple,I can't stop messing with it myself,my mates meant to be learning and I keep shoving him off for a go myself
As I have said before having the hundred amps of power behind it is uncanny,the power is just weird.
Once I have let mike get to a point in his learning,I'm gonna say sod it and get 100 feet of cable and my Motorcross gear/helmet on,for protection and have a bit of fun and go to a deserted field,and hit full pitch and see how fast it goes skyward with that 100amps behind it.
From the presence of raw power you get it will probably rip the head off.
Anyhow video tomorrow,and thanks for all your interested.
Final word: all you trex 450 learners,just drive to a field,hook up to your cigarette lighter and,practice,practice,practice,with zero interruptions(no charging lipos) as practice is what it's all about with flying helis
Regards
John

hey, in the early 90s, they came out with a 7.2 to 9.6 teathered box to hook to a car battery, I still have one, came with about 30 feet of cord , worked then and it sure as heck will work now!

May well work but I would not advise it. If it was a viable idea I think it would be commercially available by now.
A sim would be far better and allow him to advance quicker by giving him confidence also he can do it alone. You should not fly alone and especially not learn on your own just from the safety aspect. He can also practice any time he has spare regardless of the weather and having to lug around heavy batteries.
My wife practices on a HDX500 with training gear and has no problems or crashes. As said before after about 5 mins they find brain fade sets in and a rest is required or it all goes pear shaped and they learn nothing.
A couple more cheap (Turnigy) batteries from HK would also help.
I applaud you for lending your heli for him to learn but would suggest that you rethink the tether idea.
Just my 2c worth
If it cannot fly on it's own, then I won't be much help....

well, 5 min is just to short for electric, when I learned how to fly! """ own my own"" and on nicds and nimh! it was hard, just get in the grove and the batteries go dead! I had a eco 8 that would fly 7 min on nicds which was good. but then Charlie Wang came out with a 3S4P 8000 , my flight time went from 8 to 35 min,
yeh! the teathered trex isnt the right way if you want a long flight time! its not setup for long flights, heat is an issue!
if I wanted to fly a 550 or 600 for long flights, a motor change and gear change , wide open throttle on 4S 5000s X2 in parallel of 1700 max, then you can gov it down to 1500 where you can optimize the system for efficiency , 15 to 20 min flight time on that setup.

but theres nothing wrong with the 2 12V batteries, sim just isnt a real heli! yeh! you can get the basics down, then go out and teather it

Viable
Take a look at the video uploaded to YouTube link to follow.
As you will see from the video it's perfectly viable.
I felt the temperature of the motor and speed controller and they were cooler that if I ran them on a 6s lipo,don't know why,maybe cos the helis only turning a head speed of 1600 and gentle hovering no 3d.
I wonder what the heli motor makers would say if you said you can't run there motors for more than ten minutes,I bet they would say,based on gentle hovering at low head speeds they could easily be used for at least 25 minutes.
Lipos when learning:
Example.
Wake up on a Sunday morning,suns shining,you wanna go practice.
Drive to the field with your four charged lipos,everyone's at the field and within half an hour all your batteries are used up and you just got to sit there scratching your balls watching everyone else fly.
With the setup in the video you can at least go up the field and spend all day there praticing.
what's so dangerous about putting the batterie box 20 meters away from you and flying off a cord.
In the video you will see that I was flying the heli in my back yard as it was very windy and it wasn't worth traveling to the flying site,so I did the video at home.
Ok the heli was a bit close but I have 25 years flying experience,(12 years heli,13 years large gas planes) and I just wanted to get the video up.
Clive45
If we asked 10,000 heli pilots how many had flown on there own when learning or when experienced,then how many had not,I bet if we put a dollar in the hat for every one that had, I bet I'd be a far richer man than you.be carefull when walking down the road you might get run over by a truck,so you better stay in doors the rest of your life
Misskimo your right a sim just don't cut it.
When I first learnt,I went on a sim and got bored within 10 minutes,it's not video games I wanted to play,I wanted to fly helis and smell that nitro.
It's a bit like watching porn,it's just not the same as the real thing
Clive45
Brain drain is down to the quality of the brain in question.
When I learnt I just wanted to fly,fly,fly,how about the rest of you.
Clive45
The batteries I'm using must be the smallest car batteries you can get and have them in an old fishing box that I easily carry over my shoulder,anyhow we drive right up on the the flying site within 20 feet of the flight line so theres no lugging involved.
You will notice from the video that the wind was howling but I have flown this in still conditions and it's very stable.
Video in 10 minutes
Regards
John
