Now tell what's up with the talon 90??? I'm using one I haven't had any problems with. What is there to be worried about??

If the performance matches that of the 500dfc you guys are in for a treat
lovin the new gear ratio everything stays cool from 75%-100% throttle.

What is the setup of your 500 DFC and is it similar to the heli in this topic? Is it a low KV motor with a many tooth pinion?

Setup is everything, All my heli's can fly far better than I can pilot them

it's all stock
134 main, 12t pinion, 11.16:1 gear ratio, 1600kv motor, 6s3000 25C

So what are you saying? Your KV is almost twice the KV of what we are talking about,,,but a different heli. What does this have to do in comparison to a 800 something KV with a 112 main gear with a 16 tooth pinion??? Please explain in detail...

You can't even compare the 2. This is one in its own. The only thing that will make it work is the smaller main gear. Nearly 60 teeth smaller than the usual. And the larger pinion. I will like to see how efficient it is??? It may not be any good at all. Depends on how the pilot flies. Scale? 3D??

Hi Guys

I just ran Mr.Mel Head Speed calculator off RH site.

The new vs old give about 25 rpm difference..... so fundamentally the same. Just different Kv and pinion to give the same rpm... both off 6s.

New is always better......

Regards
Paul

the 500dfc is the 550's smaller brother and the new gear ratio is more efficient.
that's what I was getting at.

sure you can run the 550 on 6s but most will likely use 12s

Ok ,,I get it.. So you are saying the new 550 setup is more efficient [low kv motor and steep gearing] than the previous setup. Does anyone have any experience in this type of kv and gear ratio?

What was wrong with the previous setup? It flies great I think. But why the new motor? Is it going to have longer flight times? Or is it geared strictly toward 3d?

from what I see it will run a HS 100rpm higher than old version
I would have to guess this is more efficient motor.

I havent done the calculations but i bet you could run a original pinion and 8-10s...

Well if I am correct they are still using the CC Talon 90 like the older version. a guess would be that it uses the same or less power on a 6S compared to the higher Kv motor.. Then again a 100 rpm difference is easily made up by a different pinion. Maybe the 100 rpm headspeed improvement is needed to use the Talon 90 more efficiently and get a higher headspeed from it's Gov? I wonder what is the real benefit in performance and efficiency of this new setup is compared to the old or present 550? Or is it just a sideways move? I ordered the 550 dfc [not the newest one] an am really looking forward to it!!

Its a lot bigger motor, so it is gonna have more power, im not sure why they used that KV, maybe the shape of the can and the wind dictated it, its not unheard of the gaui x5 6s is 910kv. I dont get why align doesn't use adjustable motor mounts, So easy to do. then you can changes pinions based on headspeed target. I fly with bunch of newer guys that love anything from the align factory, im a little more critical, but they buy these 700 DFC Pro, 800 dfc Pro, and so on, they are made to be run at 2200-2400 and 2000ish but they fly them at 1400-1500 the stock castle esc without active freewheeling gets so hot, logs show a steady climb to 195-200 degrees. And all they are doing is flying circuits and hovering. I tell them they need to up there rpm before they burn out that ESC, or change to a lower pinion but they dont wanna buy a pinion and then an adjustable motor mount. The KDE one works great but they dont wanna pay for it.

They'll pay for it when their ESC goes POOF
you spend how much on kit?? then cheap out on the set-up don't make sense to me.

I'm willing to bet this new kit with a smaller pinion would get pretty good flight times.
I think you start running into problems with dfc and low HS though
I may be wrong on that

I would think so also but correct me if I am wrong that much below 2300 head speed the tail gets soft because of the gear ratio.

your right hadn't thought about the tail guess you'll have to experiment a lil

I'm flying the 500 dfc at a pretty low head speed and so far the tail is holding well while doing funnels and backwards flight with wind

of course only time will tell how this new ratio works out

Here is Align's description of the new power plant from their website::::::::::::::::::::

Brand new T-Rex 550E PRO DFC incorporates all new design elements, focusing specifically on upgrading the power with a 700 class motor, the 730MX (850KV). With a size that fall in-between large and small models, this brand new T-REX 550E PRO DFC features stability and agility, with superior power output that will guaranteed jaw dropping performance.

T-REX 550E PRO DFC is equipped with latest designs such as: DFC main rotor system, new 112T CNC helical main gear, new style tail drive assembly, new style tail control system, etc. The most talked about feature is the newly developed 730MX (850KV) motor, a motor normally found in 700 class helicopter but over spec for 550 class. Enthusiasts can clearly feel the dramatic increase in power and torque, while taking advantage of its higher efficiency, lower current and temperature benefits. In addition, the newly designed 2mm thick 3K carbon side plates not only enables the installation of wider 730MX (850kv) motor, they also simplify the structure, while maintaining high rigidity and easy maintenance.

The clean atheistic exterior, ergonomic design, and superior control feel; all are reasons for enthusiasts not to miss this value packed T-REX 550E PRO DFC!
