ROC Hobbies NXT vs Durafly EXF

[Konrad]

In this thread we pretty much came to the conclusion that the Durafly EXF was hard to beat when in comes to speed per dollar. http://www.hobbysquawk.com/forum/rc-...peed-for-price

I see that MotionRC has one that is in the same size class 1100mm. The more I look at the ROC Hobbies NXT the more it looks to be the better value even with the $100 premium.

The ROC Hobbies has flaps and retracting landing gear. All four of the primary flight servos are digital metal geared (the 2 flap servos are not). It comes with a much bigger motor with more torque (3638 850KV) that drives a thrusting 10x10. And to harness all this power it come with a 70 amp ESC with SBEC.

Compare this to the 1100mm Durafly EXF which has no landing gear and no flaps. Only 2 of the 4 servos are metal geared. The motor is a small high speed 2836 2300kv that needs a small 5.5 x 4.5 to keep from over loading on 4 cell. And only come with a 50 AMP ESC.

Now I’m looking for someone to level set me, but by my numbers the ROC looks to be a much better value product. This might be why we are seeing the Durafly EXF being discounted to under $100. It really can’'t (by the numbers) hold up the the ROC Hobbies NXT.

So as a speed freak that is value driven as opposed to price driven, have I over looked something?

Then there is the way ROC presents the NXT with the way Rich Baker flies her!

Anybody know who the OEM is for the ESC in the Durafly? I’m under the impression that the ROC ESC is a rebranded ZTW Beatles ESC.

I don't know who the OEM is for the Durafly ESC, but I haven't had any problem with mine. I do believe, though not confirmed, that the ROC is a ZTW Beatle. I'll probably be ordering one soon, because I've been wondering about the same things, Konrad. The convenience and simplicity of a hand tosser is very nice, but the functionality and features envelope that flaps and retracts provide is also a plus. I have access to a paved runway and I like being able to take off and land on gear with flaps if I have the option. It feels like a more full flight experience, but that's just me.

As to speed, assuming both are using 4s 2200s, I'd imagine the Durafly EFX is faster, but I have zero experience with the NXT Nemesis so I'll withhold final judgement. Where I would expect the Nemesis to excel is in roll rate, rudder authority, and overall maneuverability. Not to mention the fact that the NXT Nemesis is a real aircraft, and a very storied one at that. I've always loved the Nemesis. In fact, I don't know why I haven't already bought one.

I'll comment. I think these are two pretty different planes even though conceptually they are very much the same. I own planes of both type and use each depending on the conditions and place I'm flying. Sometimes, I want to fly a hand launch plane without gear and belly land it. Other times, I want to do a full rolling scale (as possible) takeoff and landing from the runway in which case I'll use a plane with flaps and landing gear. The RocHobby NXT 70A ESC is currently a ZTW beatle ESC though FMS is changing this in the near future. I've not tried the new one yet but I'm told it will be higher quality. Don't misunderstand, the 70A Beatle is not bad quality, it is just extremely basic. The ZTW Mantis 65A ESC we sell is actually an upgrade to the existing FMS 70A ESC (The 65A ESC actually has a higher 10 second burst rate). I don't know the quality of the 50A ESC in the EXF.

Thanks guys.

Now I have to ask about the term "Quality". This is an often batted around term. In my industry (Aviation) there are matrixes that define what "quality" is. These can be rate of returns, warranties accepted, etc. As an importer and distributor is there a way that you can describe quality to us, the retail buyer? I'm thinking in terms like returned units per hundred sold. This shouldn't expose your sales numbers (this is often considered sensitive business data).

I have to admit I've had no issues with the ZTW Beatle or Mantis ESC. I've had an issue or two with the Gecko ESC but the latest firmware appears to have addresses these. I've also had real good luck with genuine HobbyWing Skywalker and Platinum ESC.

All the best,
Konrad
