This is '3D' flying though, might be oK for speeding, might not. Very strong motor even in my 7Hv it hauled ass and that's go at least 2lbs on a 600SE.

If you are proficient with Auto's have at it. If not maybe avoid, would hate to see that Fuse trashed going in from a blown OWB / stripped Main Gear.

Thank you GG.
Currently the OWB and gear are holding well with the 4530 LE.
Would a rewound pyro be more powerful than a stock 4530 LE?

Abanihani,

Are you over gearing the motor?
A pyro 52 on 12S is recommended by Mikado to use 11t pinion.
I have a pyro 45 on my 600SX and on 12S I am using the 12t pinion.

[GimpyGolden]

A rewound P700 (4030) would not be as strong as your 4530 but would be a whole lot lighter.
If your machine is holding up to what your doing with it w/ the 4530 I'd say you'll be oK with Pyro. You must be going pretty easy on it. With my P700 rewind I could strip standard main just doing a few pitch pumps. The SX gear and CB/Brace really helps.

Logo is perfect machine for Pyro with H-Bone gear, no thrust load on the smallish bearings used in the motor.

What throttle % are you running? Should be looking for 65% max for your target head speed, any higher Jive will hit 100% PWM and run out of room for Gov.
Maybe this is why your drive train is holding up so well, no head room.
With my 535Kv P650 I am running 12 tooth.

[abanihani]

I am running regular pyro 700-45 with 12 T pinion and 12 S 4400 mah. The gear is upgraded from the SX kits, my max throttle is 63% mode 4 heliJive ~ 2050 rpm. all is good and holding. I stripped the regular gear after two flights but that was a bad mesh issue

On the L600SX I am running 60, 70 and 80% as per Mr Mel's HS calculator.

[GimpyGolden]

Well there it is then, no room for Gov to ramp up.
K wants 80% PWM not 80% throttle, they are working on better manual apperently.
Formula to find starting PWM is
Throttle % /2 + 50.
So your 80 comes out as 90% PWM, as soon as voltage starts to drop so is your Head Speed. If you had a JLog this is easy to see.

What % are you running on the SE/Uvular?

[TommyBear]

On the Uvular I am running YGE with vbar Gov.

[Mercuriell]

Fascinating thread and great project Lyn - the 4530 is a much more powerful motor than the Pyro and runs much hotter - I feel the Scorps run better on the YGE ESC and the Pyros on the Jive/Kosmik. In your 700 config it's a very attractive alternative to a Banshee or TDR - just having the single stage drive chain should be more efficient power train at the expense of a wider profile - look forward to some radar shoots on it !

[TommyBear]

Thanks John,

You are absolutely right, I have found the YGE - Scorpion combo works well together and jive / HJ / Kosmik are made for pyros.
Also the scorpion runs extremely Hot, impossible to touch after a series of speed run, while the pyro is ever so cool.
Had a few more flight this morning, cross winds were minimal and she's definitely feel as fast as my speed TDR.
I found DH 691 and CY 95 tails works well together on the Uvular and actually feel faster than Rails 696 and 106 tails.

[Mercuriell]

I am looking forward to trying the DH blades when PRC gets them back in stock. I bought an orange Uvular fuze to see if I could fit it to the Banshee but I think I may resurrect my old L600, I think the TDR and L600SE booms are the same !f you're set on the same power profile as the 4530 but the coolness of Pyro, you could try the P750, in fact I have a Pyro 750-50 Comp you are welcome to borrow and try!

[TommyBear]

Dear John,

You are truly generous and a great asset to the heli community. Thank you so much for the generous offer. As much as I would love to take you up on it, I am a little uncomfortable with borrowing it to try. But if you did feel like selling it to me know it would be put to good use .

Regards

Lynh

Brad,

Your Christmas has arrived early.
Just released is the new L600SE kit.
Essentially, it incorporates all the SX improvement whilst retaining the long shaft.
So all you need now is this kit and the Uvular fuselage.

Here is the parts SE/SX :

Just wish i had a longer 700-45 shaft now

[TommyBear]

It will be interesting to see how the Gmauro performs in a stock 600SX chassis and flying as a 600.

[GimpyGolden]

Won't even break a sweat on 600's.
I tried all I could to bog mine, no dice.
Flattest RPM curve you've ever seen on a log, if I can dig it up I'll post it.

[TommyBear]

Having flown the Gmauro today on the second 600SX and swinging only 603 blades, I can report that it doesn't feel as powerful as the 4530 on the Uvula swinging 691 blades.
The Gmauro comes down hot as well but still touchable. It definitely runs hotter than the stock pyro 45 on my other 600SX.
There's a surprise contender coming in the mail tomorrow.

No way you can compare the two with such different blade lengths.
Try some 693's with the Pyro and you'll see it shine.

No surprise here. No such thing as a free lunch, more power = more heat and shorter flights. The fact you can keep a finger on it is oK, not to hot.
Start hitting 180* (measured) and I'd look at gearing or additional gearing.

There's a surprise contender coming in the mail tomorrow.

Curious to see what else you have to test.
Have you changed your gearing to run max desired HS @ or below 65% yet?

[TommyBear]

GimbyGolden

What gearing ratio would you recommend for my Logo 600SX on stock pyro 45. I only have either 11t or 12t pinion available from Mikado.

One would have thought the same motor swinging shorter and lighter blades would feels more powerful.

[GimpyGolden]

Ideal would be 13 so I'd try the 12.
If the motor isn't feeling strong somethings up.
On shot blades, light machine you aren't even loading up such a motor.
It won't have the grunt the 4530 does on 690's but it will sure show it's potential on more demanding setup.
You need a more even comparison. Compare you stock 450Kv to your Mauro, should see nice improvement there.
Be sure to redo mode 4 on Jive each motor swap.

Try the 4530 on 600's too, won't even break a sweat.
