My stock hurricane motor is really poor.

Is anyone running a Neu 1907/2YF motor in the Hurricane 550.

I am running Twin FP2170's. I am looking for 5mins flight times.

thanks

Check out the motor testing done by other in my forum on the hurrican 550 thread.
Several folks have tried some other motors. Not the Neu but it will give you ideas on gearing and KV.

Also if you built yours stock (yes that motor sucks) check out some of the design or part problems we all have had to fix.

thanks bob,
I didn't know if i should post that question on that thread. The thread is getting pretty long.

Might be nice if the Hurricane got its own section. ( just a thought)

I built my Hurricane as per your videos's. It flies perfectly, just doesn't have much power or head speed.

If interest builds more then yea I will get it it's own forum....

What sort of flight times could you get on two FP 2170 mAh batterys? I read on one site of someone using a 5s 4400mAh and flying for 22mins!?! seems like a very very long time to me, What does everyone think?

I think the New is too big around to fit inthe frame. The Z-Power Z30 is the fattest motor that will fit.

Bob: How do you define "sucks". In your 2. flight video I see nice flying, does your "suck" means it sucks for hard 3D?

I follow the discussions about power in the Trex450 since 2004 and more and more beginners tend to use overpowered and energy-eating motors just to hover...

Honestly, the stock motor that comes with the Hurricane isn't very good.

If you would like to set up the hurricane for a scale ship for just hovering around, it would be ok. But even getting the bird flipped over on its back is quite a challenge. The headspeed isn't very high, and when you are flipping or rolling its quite a brick, as it bleeds off a lot of the headspeed.

So if you were learning, the stock motor might be fine to learn on. But after flying for a few years, I would like something that with a little more punch. Also if I get in to trouble, I want to be able to stop the bird without stopping the blades from lack of headspeed.

My collective managment isn't the best, but I guess I am spoiled from learning on a Trex, which has crazy power to weight ratio. Now that I am moving up to bigger helis, I base everything on what the Trex can do. Power wise, it might get expensive. To have the same performance.

Power is safety. Even if you do not fly 3D the power in a good 3D system will save you butt if you have to bang the sticks to save you heli from a loss of orrientation or a dumb thumb moment.

Hi,

it's the same in my case. I fly my T-Rex 450 SE with very good 1500 mAh batteries. That means just 4 minutes; but these 4 rock!

I changed to 515mm Blattschmied Carbon blades, and it gets a lot better!

But I hate the GAUI motor! Poor RPM and it gets hot. My 450F on the T-Rex stays plain cold!

cheers from Lake Constance, Germany

I should have my Huricane 550 on Monday. I ordered a Z30-1100 motor with it. Everyone says its a monster with that motor.

Let us know how it goes with that Adrian...... Some vid would be nice too :)

When are you going to fly the similar combo you have?

Z-POWER Z20-KV980 where can you buy this motor?

Hi,

what do you think about the Thunder Tiger Motor, they use in the E-Rappi 550?

Its the same motor as the Z30 1100kV by all accounts, just badged for TT. I've compared them side by side, and there is little or no visible difference. Even the box and the connector pack supplied is identical.

I have a Ripper 30 waiting to go in mine, but sadly been waiting for over a month for 5S packs to with it... United Hobby were out of stock and slow replenishing! ;(

I belive you can buy it next week from Backman rc expert (long name :D ) in TX.

I ll try again .

Can the Hurricane stock motor handles a 7S ( 4S + 3S = 25.9v) li-po setup with a capable HV ESC ?

Duck - No one has tried that yet that I am aware of.

I'm running a Neu 1907/1.YF on 8S. 15T pinion w/ a 61 T gear as a primary. Fits fine after I added a washer or two to the aileron control arms. I get about 9 minutes of sport flight at 2000 rpm... I think this motor is perfect. Only draws about 13 amps in forward flight. The hard 3D guys would need taller gears, but I'm already at my skill limit. This motor has much more to give then I am asking...

can you explain what you mean buy taller?

also maybe some pics of how you mounted it and modified the aileron levers please.

By taller, I meant less reduction. My ratio is 13.06:1. To get to 2300-2500 you'd need something like 11:1. Doable w/ the RevCo gears I think.

The mount is super simple. Get rid of the 3x10mm screws holding the control arms and replace them w/ 3x15mm screws. When you mount them on, put 2 M3 washers between the arms and the frame. I just grabbed some dubro stuff. Then dremel off the excess screw that holds on the ball-end from the back of the control arm (this will drag on the sides of the motor).

Do this and you've got enough clearance that the arms don't drag the sides.

Here's the pics...
