Z-Power for Trex 600 on 6S

Hello.

QUOTE: Charlie (yes rotorworkz) has 3 frame choices for the 600.

1) A stock G10 frame set that are a direct replacement for Aligns frames. Some changes are in opening in the frame to allow larger motors and such.

2) the HFE (Helifreak edition) which are design to remove all the servo bell cranks and use smaller servos like the 9650's direct to the swash. THis is all to lighten up the heli. It also allows for the motor to be mounted on top thus improving weight distribution around center. and allows for larger motors.

3) The HFX (Helifreak Xtreme). THis is a new design that allows use of larger full sized servos direct to the swash (no bell cranks). It has some pretty cool features like servo output shaft brakets to better support the servo output shaft for direct to swash connection. I will be doing a build series on these frames like I did for the HFE.

Hope this helps,
Bob


As I understand it, has Shauntot a T-Rex 600 ALU with full size servos, acording to Finless is HFE not a option as it uses smaler 9650's, but may be one of the other two?

Kgfly, I think Shauntot is in a very similar situation, as I was about one month ago, but I can't se the right solution? You then helped me, do you have any ideas?

If I was in the same situation, I will consider the coming NEU 1907/1Y with a MSRP of $173 and cut in the frame, but is there other alternatives?

Steve - thanks for the info. 550 blades aren't an option unfortunately down here in SG, good 550 carbons are hard to come by. I'd like to stick with my radix 600. i agree with u, it's pretty hard to give advice, so i was hoping someone reading using the same setup would pop a video so at least we can see how the motor performs. oh well...

Kgfly - $30 for 1 side of the Rotorworkz G10 frame, so $60 for both. pretty cheap

unfortunately - i think it still won't work if I get a bigger motor such as the Z50-800, unless it works good on 6S.

My target is to get a motor that will work on 6S, so I can use my existing packs and not have to get new lipos. If the z50-800 works nicely on 6s, then i'll get them rotorworkz frames

Taking another look it seems to me that at 800kv the Z50-800 seems poorly suited to a 6s setup. So your choice in terms of what others have used and reported on seems to be amongst:

600XL (1650kv, ~$125) - fits current frame, plenty of performance
Z30A-1100 (1110kv, ~$105) - fits current frame, probably adequate performance
Neu 1512H/1.5Y (1900kv, ~$250) - fits current frame, plenty of performance
Neu 1515H/2.5D (1700kv, ~$300) - fits current frame, plenty of performance

There are possibly some other options other brands but if so I have not seen them mentioned in the forum discussions. It has become apparent that for a 6s setup there is no need to modify or replace your frame and that if you want to follow an well know and tested 6s setup then really it is between the 600XL and the Neu. The Z30-1100 will definitely work but there is a small risk it will fall short of your expectations. Of course at only $105 you are not taking much of a risk, if you don't like I bet you could sell it easily and get a Neu anyway.

thanks for the sum up KGfly. I agree it's either 600XL or Neu for a tried and tested 6S setup, unfortunately the XL seems a hit and miss if you luck out on a motor with the shaft problem. I'm now considering the Neu 1512H/1.5Y or 1515H/2.5D as well, I'm gonna have to fork out extra money but at least it'll be a quality job.

Went motor hunting today and saw this, not sure if it's known there in the US, it's made in France, can I ask for your opinion on this motor based on the specs below, as I'm no electronics guru it looks like it can run on 6S, KV is almost identical to a Neu 1515H/2.5D. Around $200 USD and will fit stock frame.

I am far from an expert but happy to share my opinion

I have not come across that brand before so have no idea of their reputation.

The Cyclon Heli 1600 motor is about the same size and weight as a Z30-1100 which for comparison is rated at 67/84A, 1450/1800W (cont/max). The higher KV of the Cyclon will mean a smaller pinion which all else being equal, could mean less bogging but the lower KV of the Z30 could mean more torque which could also mean less bogging. The Cyclon specifications show it to be slightly more efficient.

The Cyclon is twice the price of the Z-Power so for me, given it is an unknown brand and from the specifications does not seem to offer a huge advantage, I would probably choose either the Z30 as a budget motor or stretch to the Neu as a known high performance solution.

[shauntot]

Hi Kgfly - hmm, didn't realise that the specs of the cyclon and the z30a were about the same, i thought the higher kv played an important role of being more efficient, vs. more torque for the lower kv.

for the 600, what would be better?

[shauntot]

ok i'm sold on the Z30A-1110 coz of this (vid courtesy of Ash of Trextuning using the old Z30 version)..looks and sounds alright...A should be even be better.

Getting one this week from LHS, I'll be sure to post a FDR graph for you folks looking for a cheaper alternative to the Neu or more reliable XL motors. If it doesn't satisfy, then it's time to get a Neu
