Ability to charge them at higher rates, better discharge rate and generally less prone to puffing over time (this last one is pure speculation from my side) is the reason. But - that's just my view I found Flightmax (20C) batteries losing their original power after 20 cycles, while nanotech are still holding and I have them around just that number of cycles...

True - if you have cheap blades to take all the power - fine. In my time I went for strengthening everything and ended up with main shaft/main gear (and a link or two) to be the weakest parts. But that was on MT...

Don't know. I'm talking from perspective of beginner switching from original MT (OBL) motor to Scorpion and how night and day it sounded. It gave me far more confidence knowing that it won't be easily bogged when trying to wrestle it off gravity and inevitable. And it worked - it managed to save my day more than once. And it is, so far see as, one of the best value for money motor...

Good servos, powerful motor and ESC that can handle it and good tail servo/gyro combination are always worth - no matter what frame you're putting it to. Power to save you from crazy situations (you don't want to crash because you were bad at collective and it started heading to the earth and you can make motor to pull it out of it), servos to survive crashes and sustain torque needed for head (today most servos can do it relatively easily - before it was bad idea going with 'cheap' hs55 servos instead of 65mg...) and tail combination to keep the tail in right place when you suddenly bog it...

That's how I see it... It worked for me so far!

Hi All,

I just got the $10 HK 450. Got it mostly together last night. Just have to root around through my spare junk to finnish it off. Wow, this heli is really cheap. And I mean that both ways. But hey, to repalce any part on the heli... its only ten bucks (and HK's shipping).

I though I had already joined this group sometime back. I guess not. So I'm a nubi. Of course, I would have gotten here sooner, ifn I had known there was CAKE. How come no one ever tells me about these things?

Fry

What is going on... I was in a totally differrent thread a few seconds ago.

Just so you guys don't think I was lyin' to ya!

Hey, you bunch of lunatics!

Little vid I was presented w/ after flying w/ a couple of buddies. Kept the heli somewhat closer than usual for cinematographyís sake. Donít usually fly that close; donít wanna lose anything else, know what I mean?

Iíve managed to develop fairly good control in all upright orientations, working now on upright backwards circuits, and inverted circuits. All in good time.

The HK450 is completely stock except for the 500 landing gear, which will come off this week in favor of the original undercarriage. Those tall, wide skids sure were confidence builders and kept the t-rotor nice and high. But now that I can keep the blade tips and the tail out of the dirt, theyíre a little heavy to lug around. What a sweet flying chopper. Of course, being a nubee, all I have to compare it with is my Axe 400. The Axe is the second heli on the vid. I continue to fly it because itís twitchy and keeps me on my. . .yeah, you know. Besides, itís the one with which I learned to fly, has been wrecked more than twenty times, and it just wouldnít be right, now that I donít crash so often (31 consecutive flights, no fatalities), not to fly it until itís just plumb worn out.

Sp00fman, how do you like my Tx-gloves? My mom in law made them for me. Toasty!

Would someone please figure the head speed on both choppers for me using that tach software? I sure would appreciate it.

Hope you guys enjoy it. Thank you for the great info packed into this thread.

I'm still trying to decide what is more impressive. Flying a heli with your toes, or getting your wife to do your repairs.

20C might be too little for a fairly heavy bird perhaps that's what did them in? My last lot of Flightmax lasted 60 flights (on a B400) before they were delivering noticeably less power towards the end of the pack. At this point I switched them be fixed wing packs where the power demands were lower.

Yes ultimately there has to be a fuse somewhere.

We'll go through a good few packs before he gets into a situation where a save with full collective will be required so I might start him with the cheaper motor so he can get a good taste for the hobby without spending a fortune.

Reading the reviews the motor listed doesn't seem lacking in power?

Thanks for the advice clicky.

Inspirational flying Jules. You have that little bird doing exactly what you want it to, smooth and precise. I really enjoyed watching that vid.

On a completely different note.... Your camera man is great "do that again... it was so fast I didn't get it...[pause]...I don't even know what you did....[you do another nice tight loop/flip]..............holy cow look at that."



Take it easy all.

Unfortunately the music in the video makes it impossible to do a tach on it using the software.

Thank you, guys.

Any one of you, in my shoes, would have done the same thing.

Barak, thanks, I was afraid that would be the case.
