Stretching out my 600E

[JD]

Hey guys,

Im stretching out a 600E to swing radix 690's and other than a full metal head what do i need to look out for?

Will this setup handle hard 3D?
Can the plastic tail rotor grips handle 95 or 105mm tail blades?
Has anyone who has done this already had any failures and if so what?

Im not planning on going over 1850 or so RPM on the head.

Any tips and or previous experience is helpful concerning getting the mechanics ready to swing the heavier blades. Im just a bit worried about punishing a machine designed to swing 620mm blades max with larger blades on the head and tail. To date, the only setups i have personally seen pictures of appear to be ships made to do AV work and not really heavy 3d...

the 600 Nitro and 700 Nitro Tail rotor grips and hub are exactly the same. no difference.

i am thinking this way with my 600 as well.
a good 12s setup , ie cc scorp , 12s 3000's , 690's, 105's would be a hoot.

if you are ordering 690's make sure they have a 12mm root.

i suppose we will both find out how much it will take.... keep the batterys around 800-900 grams and around 400 grams for a motor looking in the ballpark ,

it would/should fly smooth 3d without much fear.

ballacula ? on here has one that does some sport flight with it i think..

the 700 with 14mm main grips 710's , and 110's would be more of a 15's lipo ship IMOO

3000mah packs? isnt that a bit light? I would expect only around 3 mins of flight with that or am i calculating wrong?

I was thinking pretty much the samed as everything you said except 4000-5000mah
10S1P.

Hmm....another problem ive seem to run into... i cant seem to find any 6mm 0.7 module pinions.... im going to run 10-12s lipo on mine with a scorpion 560kv motor so i guess i will need somewhere between 14 or 15 Tooth pinion for 12s and a bit bigger for 10s and seems the motor comes with a 6mm shaft instead of 5mm like all the align pinions and the mikado logo pinions.

Come someone point me in the right direction for a pinion for the scorpion motors?

if you fly 3d , light , if you just cruise circuits, then build heavy .

you cant really have both ... besides 4000-5000 packs with 690 in heavy 3d are maxing out the head BIG TIME,

you want to hit it real hard no doubt .>? light weight is your best shot imoo.

or


buy a 700 with the beefed up 14mmm main blade root and an 18mm main shaft , and run 6,000 - 10,000 ma packs . at 15s.. balistic!


its a saftey issue overloading the bird 30-40% then expecting it not to fail under the same load it was designed at . you have to be serious or someone could get hurt

the only other problem i can see is boom strikes... the head is kinda low for 690's and big blade angle changes

Hey JD:

www.helihobby.com has the 6mm mikado pinions. Use their search tool and type "Mikado pinion".

It will lead you to the only 3 6mm pinions I've found. 15,16,17 tooth. Mine arrived within 3 days. I run the Scorpion 500KV. Let us know how well it handles 3D when your done.

UNited,

Great tip...thanks alot for the help on that. Gonna order right away!

EDIT: ARGH! Just went to order and they want to charge 25 dollars shipping on the pinion making the total come to over 50 USD for a single pinion. That's a bit silly i think. 50 bucks for a pinion. Gonna keep looking...

BTW, my build is done as far as the mechanics. Just need to order my zippy lipos (waiting on stock) and my pinions and motor.

Isn't Mikado in Germany? I would think you could find them somewhere in Europe and hopefully pay less shipping than from the US. The US is currently having a shift in Mikado distributors and retailers and supply has been somewhat limited lately.

Yeah one would think but ive been having problems finding the 6mm ones here in europe... i will of course keep looking and im sure ill find something eventually. Just need to look a bit harder. Knowing they exist is already a good step. Before you pointed them out to me i hadnt seen any 6mm mikado pinions at all.

Hey JD:

Align has some 6mm pinions coming out in the size you need. 14 and 15 tooth. It probably won't be long until they are available from a local dealer/hobby shop.

[JD]

Yeah its funny you mention that....i was looking into that as well but i couldnt find on the existing pinions they make the ID of the pinions. Have you seen these on the align site or heard it word of mouth?

Hi JD,

here´s a link to the mikado page.
http://mikado.e-vendo.de/e-vendo.php?shop=k_mikado_e

Look at "Spare Parts" => "Pinions" => "Module 0.7"

I´m also on the way to strech my rex, but I can not decide on which motor to use

[united737pilot]

Those 2 new pinions say the shaft bore on the Align website. They are for the new 600ESP which will have a 6mm shaft motor.

Thanks alot, man! I think i have decided on the Actro 32-3 for the simple reason that i have heard too much about bearings in the scorpion motors and i feel that the actro motors are better tested and more widely used in these types of applications. Also I can use this motor in a 700E conversion if i cant get the 600 mechanics to hold up to the abuse i intend to throw at it.

[bencho]

First I also thought about the Actro, but I heared about breaking shafts and other issues. A really good motor would be the new Kontronik Pyro:

http://www.kontronik.com/Index2.htm
(sorry for the german link, but the engish version is currently offline)

It´s more expensive but you will get something for your money:
.) 5000W
.) max. Revolution speed is 25.000 RPM
.) and really light with 375g
.) Price is 289€

[JD]

I think the PYRO is a BIT too wide for the 600 frames.

Hey JD:

Got my stretched 600 dialed in. CC85HV, Scorpion 4035-500, 18 tooth Gov mode HS 1850,1925,2000. 690 blades on 12S 2500mah believe it or not. The difference between this setup and 600mm was an avg of 4amps higher than the 600mm setup

Super light at 8.6lbs (3900.9g) and flys really good. Pics and graph of second flight. Can't believe how well the gov worked with this setup. It had a horrible time spinning 600mm blades and trying to hold HS on this same heli. Now with more headroom (since this gearing can turn 2400RPM) HS holds solid

This heli was born as a Nitro originally.

Hey Man,

I also have mine dialed in and about 6 flights on it so far. Flies great! I somehow didnt believe that such light packs would be enough so i went 12S 4000mah and guess what. You were right. I can fly 8 minutes on it and still only put 2700mah back into the packs. Not at all what i was expecting.

One thing tho. mine balances perfectly CG with the huge 4000mah packs on it. Cant imagine how you got yours to CG properly with 2500mah packs. Got any pics with the canopy off?

How about the flybar? Did you leave stock or what? I have the old 400mm FB on it now and a 440mm flybar is on the way because its just a bit too slow on cyclic for my liking. Ive tuned it almost to where i want it with max throws and some expo on cyclic but i still want a bit more so hoping that the 12g paddles and the longer flybar will put it right where i want it.

Lots of power and endless flight times for an electric. I could get 10 mins plus easy on this setup. Quite incredible. Running mine at 1940 RPM. I also went with the scorpion 4035-560KV and a 15T pinion in the end and have just upgraded my HV85 esc to 2.00 beta and will be trying the new gov features when the weather allows.

All in all im extremely happy with this heli... its much nicer than i would have dreamed and somehow i got it right first shot. It just works and flys great. I flew it more than my 700N's last weekend.
