Finaly recieved my parts today.
Included are :
Scorpion HK-4035-560
Eagle Tree display panel.
Castle Creations USB link cable.
Scorpion Bearing Lube kit.
Turnigy 15 Amp 6 volt UBEC.
Silicon wire for connecting battery and Deans Plugs.

First thing to do was Drill the frames using Phils template, works a treat, so frames were drilled.
Next i mounted the Engine mount into the frame then fitted the Main gear and Auto gear and then installed the main shaft in the chopper. Found i had to take some meterial off the engine mount to allow clearance for the Tail Drive gear to clear the engine mount.
A few passes at 50,000 RPM did the job :D
Re fitted up the engine mount and clearance was perfect, not touching anywhere.
Next i fitted up the motor and main gear into the chopper, installed the pinion gear onto the motor and got the propper height for the pinion to run on the main gear. Next in inserted a grub screw and nipped it up while keeping the pinion in the correct height position.
Then removed the whole lot again and took the pinion off and found my witness mark in the motors main shaft. Then i wrapped the motor in tape as the magnets will attract any metal i remove from the shaft, got a sharp centre punch and marked where i needed to machine and proceeded to machine a flat on the shaft for the grub screw to lock into so the pinion wont spin on the shaft.
Refitted the Engine to check pinion height and all was good, so now the motor is basicaly installed and ready to go. Now its onto wiring it all up with the Castle Creations ESC and the UBEC i have to install. I also need to make up my batterys series Deans plugs and a few other little bits.
More to come soon.
Looking good !!

Nice pics! Does anyone know if there is a motor-mount fitting a Kontronik Pyro motor? I've heard this motor-mount only has holes drilled with a distance of 25mm between each other, and not 30mm as the Pyro motor has for it set-screws.

[boosst]

your setup look really familiar:YeaBaby:
your going to love it!

[viperhawk]

You're going to love this helicopter.

[duke666]

The heli-chris motor mount is drilled for any motor.

I have done this mod to mine too and I love it. Are you running 6s Zippy packs? It's a 12s 5000 right?

One thing I would look at is the autorotation drive gear hitting the mount block. I found (and others on this site), that it can rub against the motor mount block. I dremeled a little depression in the mount block to allow adequate clearance for autorotation gear to clear the motor mount.

I'm running a similar setup with the CCHV 110 as well as the Scorpion 560 motor.

I mounted my battery in the back after creating a battery mount to bring the CG closer to the rotor. It also helps clear the cross frame brace for the tail boom braces.

The Zippy packs are great and are a good value for the money!

[roinides]

Doc Joe nice setup.

I am also building my 700e. Neu motor 12s5000mah thanks to ZIPPY !!!!!

I will make a tray also there in the back.

As for the motor shaft and pin it, i will only throw some loctite in. I do not want to mess with the shaft of my Neu...

[knasbollen]

Hi, just wondering about the headline, is says 12S10000, I assume you mean 12S5000 ? If it was 10000mah you would need four 6S5000 packs =)

Seems like a nice setup, you will most likely have a lot of fun ;)

[helibrick]

That's just asking for an unintended auto. With a hardened shaft, temperature differentials, lots of torque and 5 HP, it's just a matter of time with just one pin and no flat spot.

[roinides]

Well in this case, whats a little pin in the shaft ..?

:)

[GenReaper]

Thanks Guys especialy docjoe (http://www.helifreak.com/member.php?u=7513)

That gives me a great idea now on how to mount the rear battery.

I was going to space it with some form of block underneath the battery and tie it like you have but looking at what you have done, that would seem to be the best way to go about it.

Cheers, Brad.

[t-rexn8]

Hey docjoe can you make me one of those rear battery mounts? ;)

[GenReaper]

Today i made up the Rear Battery Mount.
After driving to the Machine shop i found out they were still on Holidays so no access to the milling machine :(
So i made a Custom Prototype mount by hand.
It came up pretty good and will add alot of strength to the frame.
The reliefs i cut into the mount are the exact width of the battery so the straps are held in place and the battery will not be able to move around during flight. All that is needed now is to mount the Velcro to the underside of the Mount to secure the Battery.
Took a fair while to make but it was a job well done considering it was all hand made.
It is mounted with 4mm High Tensile bolts and Nyloc nuts, so it will not shear in the most demanding moves.
Had to drill 2 holes in the rear of the frame to mount it with but thats fine, the frame is very strong now, should help minimize any possible flexing.

Thinking of going electric as well on a 700 can someone tell me the clearance below the motor to the bottom tray. Thinking of using a 12 s 3750 lipo size 43mm x 305 x 48. here http://www.flightpower.co.uk/index.asp?page=Products/Product(Info.asp^item=FPEON28-375012SLONG

Maybe i need the heli chris conversion would that fit better?

This would give me a much lighter heli to compensate for the lower lipo capacity

[GenReaper]

Fitted up the Side Frames and Bottom plate and skids.
Re mounted the Motor Mount and installed motor loose.
Frame mod went together well.
I reused my engine mount blocks so i could bolt up the bottom carbon plate to it for added strength.
Next i will have to concentrate on Electrics placement and wire routing.
Very happy so far, all is coming together well.

The gap between the bottom plate and the motor is 59mm
Dont forget the lower frame crossmember braces are 10mm high so that leaves you 49mm not allowing for clearance and velcro thickness.

Is it was any thicker than 40mm you could have problems.

[Gopedasia]

Looking very awesome. I cant wait to read how it compares to your T6E.

[roinides]

Gen is this metal plate for battery heavy..?

Nice work !!!

I am thinking of cutting the Nitro Version bottom carbon plate , for the battery tray. I think it fits ok.
I know that it has little space for velcro , but i do not want a heavy duty velcro strap there.
I just need it to hold the batteries, and be able to get them out easily.

Lets see how we all go on this 700e. !!!

[docjoe]

GenReaper,

That is a very nice mount! Good work.

Gopedasia,

There's no comparison between the 600E and 700E. The 700E is by far more powerful! I've had a 10s 600E setup and that was a powerful setup, but heavy. I love my 700E.

T-Rexn8,

I usually only do my own stuff. I got the idea from one of the other guys here on HF. I took the metal fan shroud supports and drilled holes into it using a drill press. Then attached them to a G10 piece. It wasn't a hard mod to do.

[GenReaper]

Thanks DocJoe.

The plate is a Alloy T6065, its actualy quite light.

Joe, if you dont mind can you post any info on your setting with your 700E in the way of ESC, Pinion gearing, throttle curves or if you are running a gov mode etc.

I am going to be running a data logger but it would save me a lot of time if you could give me some specs on your machine in the way of electronics setup.

Not trying to leech info but it sure would be appreciated and would save me many cycles in setup time.

Even a screenie of you ESC program setting would be super kewl.

If not no dramas.

Thanks, Brad.

Isn't possible to set the engine-mount higher above the maingear so you can place the motor as top-mounted? Have anyone tested to fit it? It seems it is possible according to the pictures...

[cbdane]

You have to flip the swashplate front-to-back to avoid interference with the elevator arm so it requires pretty significant cyclic servo reorientation. Heli-Chris.com sells a complete frameset that does this.

[Vantskruv]

Cbdane, okey you meant that it will possible but it is awkward work to change the links and recalibrate the servo? If I would buy this helicopter, I'll sure not buy the helicrhis, it is a way too overpriced. Instead I would go for the cheapier version, maybe align will release a TREX 700e after a while, and I would rather go for their parts instead because I guess that would be a more easier and cheapier way.

[duke666]

This is the same post I replied to you on RR! It is possible to flip the servo and A arm but only using heli-chris, excellent solution and well worth the money (IMO). if you just try to mount the sero and A arm at the rear you will realise there is nothing to attach it to, chris frames are much higher at the rear giving something to mount to. And evev then that servo is tight in there. The cheaper version works fine, but I for one prefer chris's with the motor up top and lots more room for the lipo below,and at the moment he can't manufacture the kits quick enough for demand.

Regards Duke
