24 volt truck battery for hover training
Hi all
Can someone confirm or correct my following question.
A friend of mine wants to learn to fly helicopters and the only heli I'm willing to lend him is my 550e.
I only have 2 x 6s lipos for this so he's only going to get a couple of short flights,per charge so the question is if I run an additional 10 foot of wire from a 24v truck battery and zip tie it to the training legs then connect it to the esc this should give him a full hour or two of continued hovering practice, as mastering the hover is something that is key.
I feel that you can spend a good twenty minutes praticing the hover,then have a 10 minute break,then another twenty minutes,then another 10 minute break and so on.
With a 24 volt truck battery you could potentially,get an intense training session,a bit like a 7 day intense driving lesson.
The 24v truck battery is a heavy duty type and is rated at 180amps(180,000 mah).so I'm assuming this would give at least a couple of hours hover training.
Let me know what you all think
Thank in advance for any help received.
Regards
John

Tether
Hi olroy
Yes great I found this on YouTube:
http://www.youtube.com/watch?v=y_lT...be_gdata_player
this is good, never thought of that,but what I meant exactly is just using a single power cable to give the esc extended power for continuous hover training,just hovering/ hopping a few feet off the ground until he masters the hover.
What I would like to know is,if it's possible to run a trex 550e off a truck battery without blowing up the motor/esc.
My thinking is that the esc I have handles up to something like 30 volts input,a truck battery is 24volts so the voltage is under the 30volts max input,and I assume the esc will regulate/look after the motor.
I don't want to tether the heli,just run an umbilical cord to it for extended power times.
What do ya think
Regards
John

I used to do this with my Eco 8 back in the day. I used this cord to run it off a car battery with a car battery charger boosting the power. http://www.fxaeromodels.com/product...roducts_id=2071

Part of me really wants to encourage this-- with a devil on my shoulder. But the angel on the other side says-- HELL NO, DO NOT DO THIS!

A beginner is just that, A BEGINNER. Somoeone that cannot predict the sudden movements of a large helicopter leaves no margin of error when the heli ends up somewhere unexpected....as the tether yanks the heli, sending it plummeting to the ground--possibly out of control if the power source has disconnected.

Get a buddy box.

Sounds cool if he can keep it within the limits of the tether itself lOl. Chances are he won't and/or the sudden gust could send it towards the tethers limits planting it into the ground (I can picture it now ). No matter how much I would love to see this I cannot say it is a good idea.. Polo

What about a tether combined with an umbilical cord as video posted by olroy,seems good enough in the video and stop any uncontrolled flyways?

A truck battery is of course just 2 12v lead acid batteries in series. Its doable but just keep in mind the power loss through such a long cable and also make sure he doesn't have too much negative pitch that could suck the cable into the blades upon landing and spool down.60% of the time, it works every time!

Put him on the simulator to learn all the hovering stuff. This will be much cheaper for you.High Voltage just works better

RTF..first post! No inverted flight or even FF, just hovering.
