HIROBO Freya - Sceadu - Shuttle > 600 mm blades on Shuttle Plus
 
 
Bert Kammerer

Location: Orlando, Florida

I have managed to successfully stretch my Shuttle Plus by changing the boom, belt, tail push rod and boom support arms. I am now running 600 mm blades and the heli performs very well (electric powered).

My question has to do with the blade grips/holders. Have any of you ever done this and/or otherwise do you think the standard blade grips are strong enough to hold those 600 blades? I was thinking it would be safer to run metal blade grips, but wouldn't want to spend the extra money at the moment.

Any comments are very much appreciated.

Depends

I hate to put it this way, but I believe, "it depends."

"It depends" on what kind of stresses you will be placing on the rotor head, shaft, etc. If you will be doing forward flight, and such without extreme acro, with reasonable headspeeds, etc., it will probably be ok... just not sure about electrics though and their power to ramp up larger blades that also weigh more out there... (power/pitch/blade weight ratio related concerns.)

I put some fiberglass 600s on my Shuttle 30 with an OS32, and it was surprising how well it did. (I made NO tailboom changes from the stock configuration.) I was very pleased with the autorotations... talk about "stored energy"... almost as good as the ole' Real Deal Kiowa!

Those 50mm per blade of lift also translated into lower pitch values for the corresponding throttle values to achieve the same result of scale forward flight, standard turns, steep turns, etc., . I did not go "extreme flight" with it.

For extreme flight, I would gradually, very gradually, test the flight envelop, as opposed to just jumping into extreme flight. (Detailed post-flights and pre-flights are a given.)

Hope this helps some. Please keep us updated as to your findings.

Cheers,
Grover

I'm not sure your engine and clutch will like the higher torqe. I've heard of people putting in a 46 upgrade into a shuttle with 600's. And I know I had looked at converting my shuttle and I think the upgrade kit comes with a larger clutch and bell also.

Thanks for the replies guys. The clutch works just fine. The only reason why I stretched it was because I had a Hacker motor that was way too powerful for the stock heli and wanted to take advantage of the power by increasing rotor diameter. I had to get a larger boom though as the 600 mm blades didn't have enough clearance with the stock boom.

I have flown it around a couple of times, but have done slow forward flight with shallow turns, etc. I haven't done anything other than that yet and I am keeping the head speed right at around 1700. I want to start doing acro with it, but I am afraid the grips won't stand the additional forces imposed on them. I might end up ordering the metal head, I just hate to spend the money.

I believe you'll be OK as long as you have the thrust-bearing type shuttle grips, and as long as you're in the 1700 RPM range.

I ran some VERY heavy glass 550s on my shuttle at 1850 RPM with no problems. Your blades are probably lighter than those were.

I think CobraJock24 has the right idea, take it slow.

What motor/battery setup is that? - looks like something I might want to try!

See pictures of the grips and motor setup below.

I am running a Hacker C50 20XL with 6s3p and Hacker 77-o speed controller. Runs very well!

Very nice !!!!!!! Where did you get that motor mount ? I have another incomplete Shuttle and was also thinking about electri-flying it.

More details would be greatly appreciated.

Hey Bert,
for the price of a metal head, you might wana consider converting your whole shuttleand just getting an Evo 50, but you would probably have to make a new motor mount.

Thanks for the nice comments guys.

I friend of mine who bought a Shuttle that used to be electric gave me the mount, but you can buy it from here:
http://www.ewtech.com/Merchant2/mer...ct_Code=QUISP72

The all metal head would cost me $125.00 and that includes the main head piece and the grips. I doubt I can get an Evo for that price. This thing flyes great! It is truly amazing and has all the power for heavy duty 3D, too bad its pilot can only do loops and rolls and nothing more

bkammerer,

I am very tempted to convert my Shuttle to EP, since I started flying EP planks, my IC shuttle has seen very little action.

Can I ask you a few questions about your shuttle convertion.

What is the current draw of your setup (hover and max)?

you said your batts are 6s3p, but what capacity are the cells (or whole pack)?

And the All up Weight of the heli, ready to fly?

Thanks a lot,

Stuart

Hi Stuart,

I don't know the max draw, but the hover draw is about 25 amps. I used to run Thunderpowers 6s3p, which is 2 3s3p Thunderpower 6000 MaH batteries running in series. Since I stretch the Shuttle and it is now a 50 size (600mm blades and GPH boom), I added an extra cell, so I now run a 6s3p 6000 Mah and a 4s3p 6000 Mah in series. However, if you plan to keep your Shuttle as a 30 size heli (550 mm blades) you will be more than happy with the performance you would get out of the 6s3p pack.

If I had a Shuttle 30 stock right now, I would make things a little different, I would get a Hacker C50 19XL instead of the 20XL. This is what I would recommend:

Hacker C50 19XL
Thunderpower 3s3p 6000 Mah (2 running in series)
Hacker Master 77-o heli ESC

You can't go wrong with this setup. If you run a conservative headspeed of about 1700 you will be able to fly for about 12 minutes. My heli weights about 8 pounds with the 7s3p and bigger blades/boom, but a stock shuttle with 6s3p should weight between 6.5 and 7 pounds, it will be heavier than the IC setup, but not by much.

Good luck!

Nice Set up..

As in G Dogs comment.. I would like to kno where you got the conversion kit to make it Electric too.. Many thanks..

bkammerer,

thanks for sharing your project. I took your advice and set up my old shuttle ZX with the Hacker c50-19xl, hacker 77-O-heli in gov mode, and 6 tp2100 batteries. It flew very well but I had to keep the rpms at 1550 because something started vibrating when I went higher. 1550 seems to work just fine for forward flight and light maneuvers using the stock semi-symmetrical 550mm wood blades. Using a DPR50 data logger I found that hovering drew around 18 to 19 amps. Since that time I found that the blade grips (the old ones that have the metal piece) were getting soft and I am now waiting for the new style grips (the same as the ones you have) to arrive to fly this thing some more. Your suggested setup seems to have a ton of extra power in reserve should I decide to use it.

Now that I am hooked, I am getting close to trying out my eRaptor 50 that has an actro 24-4, hacker 77-O-heli, stock 10/85 gearing and will be using a 9s-2p setup using the same batteries from the eshuttle. It should be interesting. The only reason for using the actro is that I got it for a very reasonable price.

Glad to know that it is working well for you. The Shuttle running this setup is by no means a 3D machine. However, it will perform very smooth forward flight and light aerobatics, such as loops, rolls, fly inverted, etc.

I wonder what your vibration might be, I was running 1800 on the head with no signs of vibration, in fact this was the smoothest heli I had ever owned.

Good luck!

Hi Bkammerer,

do you think this e-setup will be suitable for an FK bell 222 + retracts setup ? It should be around 400 to 500 grams of weight more than the original.

Hard to tell, I think it should handle it well. I remember having enough power. I sold the heli many months ago, I think the performance though is plenty for a scale ship and hauling more half a kilo more should be no problem.

Well, on my Shuttle with MS Modelsport 550mm FAI Blades/OS32sx/Weston Pipe my blade holders with time develope a hair crack, I have change 2 or 3 sets of the blade holders for this matter.........But they usually last a long until develop the cracks

I dont know is these cracks are because I tight to much the blades 3mm screw, or because my agressive fly or because the heavy blades make this happend.

I know Hirobo have Shuttle plastic blade holders that use 4mm blades screws, maybe you can use them.

What ever you decide to do, just keep an eye on the blade holders and check for hair cracks.

Good luck,

Isaac
