Motrolfly DM4315-500 vs Torque Revolution 4016T/500

Motrolfly DM4315-500 vs Torque Revolution 4016T/500

I'm sort of new in the electric world and I'm thinking of getting either the Extreme Flight 64" MXS-EXP ARF or one of the 3DHS planes in that general size.

Just wondering what everyone's thoughts are on these two motors and which one would be preferred over the other.
Would one have more power or less flight time than the other etc?

Are there any other motors out there that may be better or at least in the same category.

I have a couple of 6s 3000 and 3300 lipos that need a home in a 3D plane.

Any tips or comments greatly appreciated.
Hope this hasn't been asked before. I did a quick search and wasn't able to find much.
Thanks.

Hi
The probability that one hobbyist have tested both DM4315-500 and Torque 4016T-500 is very small.
To compare two motors it is mandatory that the same tester, same procedure, same instruments are used, at same temperature.
Precise comparison could inform
** about measured Kv possible difference
** about no load losses (W) versus rpm (graph)
** about Rm difference
For the same Kv the winner is the motor having the smaller no load losses and lower Rm
By Scorpion you have :
HK4025-550 (measured 588 rpm/V 30 mohm), 336 g
HK4035-500 , (measured 500 rpm/V 20 mohm) 399g
By Dualsky :
XM5060EA-6 (measured 511 rpm/V 15.3 mohm) 391 g (stator 41-30)
By Cobra
C-4130-14 Kv announced 450
By Leopard
Leopard LC5065-500KV-5T
By eMax GT
GT 4030-06 Kv 420
and a lot more (AXI, Hacker ....)

A good comparative test is also to use same prop, same rpm, same ESC
(+ voltage adjusted by the power supply)

Both are great motors. Motroflys are extremely popular and the support you get from Ken at SUbsonic Planes is awesome.

It realy depends upon the plane you intend to put it into. I think the Torque motor can handle a bit more prop, at the cost of more weight, however. the Motrofly motor is a touch lighter to start with and also is available with an even lighter mounts...

Weight: 280 grams (9.86 oz.)
Weight: with Hub, Xmount, and 4mm connectors, 323 grams (11.4 oz.)

Optional light aluminum mount changes the configuration of the motor a bit and lowers the motor weight to 271 grams (9.5 ounces) and with all hardware down to 304 grams (10.7 ounces)

Optional light fiberglass mount changes the configuration of the motor as well and lowers the motor weight further down to 267 grams, (9.4 ounces) and the weight with all hardware down to 300 grams, (10.6 ounces)

Have you checked out the thread on that plane or, the Extreme Flight Owners thread, to get the opinion of others who fly that plane? I know many run the Motrofly 4315 in the 480Kv wind with 16" props. The Motrofly runs very cool compared to other options available.

I have not run the Torque, but I am very familiar with the Motrolfly's from the 4315 on down. In fact, I have two 4315-480's right now.

The nice thing about the bigger Motrolfly's is that they are all handwound by Ken, using larger conductor. They are a thing of beauty outside and in; and especially the way ken lays the wire. I guess it doesn't make much of a difference but to me it just seems to bring order to an area that is usually lacking.

Ken also uses sealed bearing in most of his motors - I believe the smaller ones use shielded bearings.

But, to be fair, I have read nothing but good reports on the new Torque.

Hope this helps.

Steve
