New Trex 450 L Dominator!

If it has more torque it will use more power, so flight time will be less. The main advantage to a higher voltage is you use less amps for the same wattage and your wire size can be smaller.

less amps means less heat, heat = energy being lost

therefore higher volts = more efficient conversion of electrical energy to mechanical energy

that warp 360 has a great design .... no feathering shaft ? now that's cool . then theres the 17 mm tail boom and 6 mm main shaft and the motor to belt to main gear , very nice . servos are easy to get to .
it does look like a strong ,low maintenance heli .
and the no electronics kit is 300 bucks @ rc711 with the upgraded aluminum blade grips , not bad.

Amps is not heat. Watts is what creates heat. Watts is a unit of electrical energy (equivalent to one joule per second). There is no free ride, a watt is a watt. You get the same heat from 110v 2 amp as you do with 220v 1 amp. Basic electricity, watts law.

amps, watts, heat, efficiency... all I know is that a 6s 450 heli will beat the crap out of 3s setup where does it come from? magic!

Conductor losses (Watts) depend on current (P=I^2 * R [W]). That's why we use high voltages for large power transmission.

Oh no, please, not this again 6S vs 3S has been debated numerous times, complete with numbers.

My take away from the previous discussions:

-Both are good
-Both can perform well
-6S seems to have an advantage in numbers. Whether it is a meaningful difference in the air, apart from a cooler ESC, may be for debate.
-With 6S, you can charge your 450 packs in parallel with your larger 6S packs, saving time. That is nice by itself, even ignoring other aspects.

And 12S beats the crap out of 6S but people are still building 6S 550s all the time... And 14S beats the crap out of 12S... when does it stop? What is good enough? I wonder when we see the first 8S 450Ls? who wants to go first?

You can buy decent 6S 1200ish batteries for 25.00USD, and you can buy decent 3S 2200 for 12.50USD.

If you wanted to get an even idea of what a good 450L 3S setup might use for a battery, the Zippy Compact 2450 would be a good size to try... it's 35C and would fit.

Slightly off topic, but I assumed the reason that the Warp didn't need a feathering shaft was because it used CF blade grips that could provide the feathering flex? With entirely metal blade grips - how is dissymmetry of lift counteracted?

tomw - I could be wrong on the upgrade .I might have been for the tail grips , I was just browsing the web page . but the warp does have some nice features , while the 450l is sleeker looking .

The warp has a face only a mother could love, but does have some really cool features. if compass had better part support I might look to try one out. but my 450L looks a lot better

The warp is a pain in the ass to work on, but is an excellent bird

I don't get what's so wrong with it's design Have you seen it? here's a picture if you did not

[Luigi_tuga]

I liked the warp design the first time i saw it.

Design is one of those personal things, no need to discuss. Some love and others will hate.
At least the WARP has a very fresh design, even compared to the rest of Compass line-up.
Just for that it scores more than the copy/paste that is the norm.

it just looks like a big pile of angry bird put on cf skids, doesnt look sleek to me compared to the 450L... I was considering one because I like all the design in it, but I can't use the align motor which I would like to switch all of my electronics, and it looks like gears strip just as easy in that heli... I think the x3 is probably going to be easiest on servo gears cause its non dfc and plastic, and it looks like their sorting out the issues.. I may wait to see if goblin makes one or try the x3 also...

[uiron]

The only head design that is easier on servo gears is FB. Today you just choose servo brand which crashes well and you can afford to fix, and airframe that offers easy access to servos (Warp is not the greatest in that regard).


..and yeah, if that stupid game crosses your mind each time you look at stock canopy, Fusuno or other aftermarket provider can easily fix the problem..

Uh oh I think I derailed the topic. Back to the 450L please. The 450L has a refreshing look I think. Anybody who has built a Trex before could easily get this up and running in an hour. This bird has lots of improvement. Kudos to Align! Their 3GX v4 flies better as well.

[mknj]

On large transmissions yes. Conductor sizes and losses are a big issue.

I especially noted the 360 blades, 460mx motor for a positive.

And the negative was the ungoverned HS- which probably means the same Align ESC.
And the DS 415 servos. Which I think have too much play in the gears.

But an otherwise stellar bird that will no doubt be the next big thing.

WoW

They are ds430 cyclic servos on the 450L. Tail is a ds525.
