not too shabby :D ...

[Tom Fiddler]

Thanks Greg
"Not too shabby" Is about as good as my flying gets!!! :D :D

[Tom Fiddler]

Eddie head on up to northern VA
She aint real fast so I think you could handle it :shock:
I have a beautiful field behind my house where we can fly all day

[Jared J]

Fidman, what'd you put in that thing?

[Tom Fiddler]

22/45/3 Mega Motor
Phoenix60 speed controller (both from esprit models)
20 GP 3300 mah Nimh cells (from cheapbatterypacks.com)
23 tooth motor pinion (from Joker USA)
1 Century Predator front radio tray (makes the motor mount and battery tray) fit's perfect between the Raven 50 frames
1 Raven 50 kit

Oh yeah, and a little thinkin

[Jared J]

Cool. Stupid question. What do the numbers mean on the Mega motor, ie 22/45/3?

[Sluggo]

nice vid Tom, How long did it take you to put it all together?

Please don't ask Tom to explain all he knows about electrics--we don't have the space or bandwidth :shock: :shock: :D

With the Mega's 22 is the motors rotor dia. (in mm), 45 is the rotors length and the 3 is the number of "windings"
All of these motors have what is called a KV rating
A rating of 1 Kv simply means that with no load on the motor it will spin 1000 rpm's for every volt you put into it.
I have found that you will get about 80% of that rating while in flight.
I average about a 30 amp draw over the flight

Note that ever motor manufacturer uses a different system so you have to look and compare some other more important numbers that can be hard to find sometimes :roll:

Also most of these motors come from industrial applications
One guy on this board is working on his own design motor
Can't wait to help him test it!


Sluggo
About 8 hours including assembly of the kit and making it fly.
Still working on making it better Once I get it just where I want it.
I'll start on a new project :idea:

[EvoHeli]

Tom,

What kind of flight times do you get with those battery packs?

Hurry up and get all the kiks worked out because I want one of those!

[Tom Fiddler]

It flies for 7 min
It flies really good for 5min
With my original gearing you could cruise around at 1550 for almost 10 min

I'm pretty happy with the current setup

[jwooten]

Great job Tom. Are you going to try Lipos next.

Jimmy

[Tom Fiddler]

Jimmy where's a video of that E-Predator?
Give it up!!!

No lipo's for me right now I'm waiting on the price to match my bank balance :!:

I don't think my Phoenix 60 is up to the Lipo's (Voltage wise)

[EvoHeli]

Ok.

Where can I download the instruction/assembly manual for one of these bad boys? :)

[Tom Fiddler]

www.centuryheli.com
Has all of the manuals online
Of course they are all glow versions

[EvoHeli]

I know :)

I need the e-conversion manual :wink:

[jwooten]

Tom,

They took some video at Birmingham but I haven’t seen it.
I spent the money for my camcorder on lipos.

Jimmy

[Tom Fiddler]

"I spent the money for my camcorder on lipos."

I laughed pretty hard at that .....until I realised how true it was.

I can see the cardboard sign "Will work for Lipo's"
