Default Trex 500 DFC vs Protos vs ATOM 500

Wondering what people would pick from the above selection? I crashed my old trex500 ESP (original generation) today pretty hard and its at least 150 to fix so I don't know that its worth it. Plus the 500L motor is not exactly wonderful and by the time I upgrade everything, it hardly seems worth it.

So I"m considering something new. Wondering what people think is a better heli, I'd like the best flying heli and if it crashes decently then thats even better. A little sick of replacing torque tube gears with every crash.

Also if I did go TREX 500 DFC, can you get those without servos as I have perfectly good servos here.

Personally I love the P500 design and how quiet it is; I would buy it again in a heartbeat.

I don't know if cost is a factor but here they are:

Atom 500 fbl w/ motor, blades, and esc: $520
Protos 500 fb w/ motor, blades, and esc: $420 (carbon) $400 (plastic frame) +another $50 for the flybarless upgrade
Trex 500 dfc w/ motor, blades, and esc: $470 (I just added a motor and esc to a bare kit [on ebay] price)

You did not specify fb or fbl but none of these prices include a fbl unit

I have the hc3sx fbl unit. It would be flybarless. The trex 500 dfc available with out blades could make it a contender but then id need 70amp esc when the others work on 60 amp so I could reuse my yep esc.

Btw, cost is a major factor along with how well it Flys, the power it has and how well it does in a crash. I Like trex because parts are everywhere, but replacing the entire tail every crash sucks and it seems the other 2 fly much better.

The 500dfc bare kit on ebay does include blades but no electronics for $340

There is a bare version of the protos with no electronics or main blades but it's not a very good value compared to the combos.

At helidirect P500 carbon: http://www.helidirect.com/helicopter...-1_29_1723.hdx
no main blades or electronics: $335 (hobbyking has a $17 3025-850kv motor that supposedly is pretty good in the protos)
no main blades, includes motor and esc: $400
includes blades, motor and esc: $420

So basically with the last combo you are getting an $80 motor, $60 set of blades, and $130 esc for $85. Also you would have to add another $50 for the fbl upgrade kit.

Prostar hobbies has the Atom 500 fbl w/ blades and motor but no esc for $450. So that's probably not a bad option either.

But which one is best out of the 3? And will the Align DFC 500mx motor work with 60amp esc? I see compass and protos both come with 60amp esc.

Do the new aligns even compare to the compass and protos even though the compass and protos are a number of years old?

I have only flown the protos so I can't answer that. I would stay with either the atom or the protos personally just because of the belted tail.

You could probably google search and find some Atom vs Protos discussions.

If your crahing allot get a mini protos and stretch it
Best flying 450 on the market and crash costs cheaper than a 425 machine

Any big crash on a 425mm machine will cost a fair bit more than a 350 mm machine

I was going to give up on flying 450 helis as I hated the way they flew than I bought a mini protos and never looked back

Warp 360 and guai x3 are two other 350mm machine to consider they look bigger in the air than mini p due to size of canopys

Hi all, this thread interests me.

I am considering a 500, but I would like the best performer.
I fly hard 3d.
The Atom is out of the equation for me. I don't like compass.
The belt is not an advantage for me, actually I prefer the torque tube because I manage it very well and I do a lot of 3d and autorotations. I have a Trex450 never break a TT unless I really crash.
My concern is :

- Weight of the machines without batteries but with canopy, can someone that has a Trex 500 pro and a protoss carbon compare give the respective weights (I want real data, because I have had a T450 and a miniprotos both with the same setup (except motor and ESC) and the weight was pretty even with a few grams less for the T450, however, everyone keeps saying the miniprotos is lighter than the 450 pro)e

- Flight time but at a lesser extent.

I love my new to me ATOM, the flybarless head is awesome, I'd say pretty much the best out there and it flys without issues. its super humid in florida so belt static has never really been an issue. Torque tubes break every crash.

I prefer avoid belts, just a personal preference. I don't mind the noise of opinions. TT break every crash. However a TT never caused me any issue unless I crash. Belts on the other way.... TT are pretty much something that you can forget forever, zero maintenance, they virtually can fly forever. Belts wear over time.
