Finally got the T-rex 600 NP Kit and have just started the build process....Finished the blade holder assembly on the rotor-head along with the see saw assembly within the hour. Hit my first roadblock with the direction of the centre portion of the thrust bearing on the feathering spindle....had to open and re-assemble to get the railed portion facing the hub to prevent the grease flying out!! .... a pain to get the locktightened screws out of the spindle...but got it right finally....now for the flybar assembly....

Great going. Do post some pictures.
Also does this kit come with some parts pre-built ? or do you need to build up everything.
I built my Raptor 50 recently, and nothing came pre-assembled . Had a zillion parts in at least a hundred plastic bags ! I am glad I didnt loose anything.

Are you also taking assistance from the Bob Finless videos from HeliFreak ? i thought i had seen the Trex 600 build video the other day . Ok here is the link : http://helifreak.com/showthread.php?t=41514

Also do post what equipment you are going to use : Engine, gyro, servos, radio

Look forward to seeing this come together.

Yup, have the Helifreak vids.....so far used just the manual for the head assembly.Everything needs to be built from scratch except some basic assemblies like the tail gear assembly etc. But the good thing is that the packets are nicely marked and tagged...here are the components:

1. T-Rex Nitro Pro carbon edition heli kit
2. OS-Max 50 Heli engine
3. Century Tri-flo muffler
4. Futaba Gy520 gyro with 9254 rudder servo
5. Hitec digital servos with 5.5Kg torq for cyclic and throttle (forget the number)
6. 600mm CF blades
7. 2000mah Nimh Rx battery (should be good for 3-4 tanks before a recharge)

Way to go Lavneet, you will love this one   Being my primary bird for about 1.5 years, I can say with confidence that if you are careful about the build and setup, it can do pretty much whatever you want it do to

BTW, did you buy it locally ? And is it the NSP or the NP ?  And did you consider the Knight 50 instead at any point ?

Please ignore the question about the NSP, I see that it is the NP, since the NSP comes with servos etc.

moderator pls delete this post
thanks

It is a Nitro Pro bought off ebay USA, had to pay some duty but still a good deal....whats the diff with knight 50? This one came with a carbon frame, CF tail blades and CF fins etc. Rotor head and Swash are alloy and the blade holders are Nylon...trying my best to build as slow , true and square as possible...

If you were buying from outside, this would have been a wonderful deal.

The Knight 50 is considered a better 50 size heli by many.  I have not flown one, but many who have flown both said that it is better.  And it is locally available in India.   But you cannot go wrong with Align either, as it is also very high quality. 

One good thing about Align is that spares are available all over the world (being the world's most widely used RC heli brand), and whatever models they come up with, they never disappoint.  So far, the first version of the Trex 250 seems to be their worst initial release.  But they also always come up with upgrades and replacement parts quickly to fix any issues. 

I did upgrade by main blade holders to metal ones on my Trex 600 NP.

full rotor head assembly complete.....

Great going. That was kinda quick ! Does the Trex 600 use the E-CCPM ?

yes CCPM

Good going

Your flybar paddle (at least one of them) seems to be not in line with the flybar "cage" (or so it seems from the picture).  If it is it not in the same plane, do remember to correct it along with your final pitch setup steps.

Thats because the set screws that secure the flybar to the cage have only been lightly screwed into the notches on the flybar to prevent the flybar from falling out. This gives the paddles a lot of play. The setscrews will be thread locked and tightened at the end after I have the measurements done with a V caliper. After that i will twist the paddles parallel to the blade grips with the help of a pitch gauge...

reached stage 2, finished the clutch and getting thre main frame together now....

Frame with tank and Landing skids assy complete so on to the 3rd stage of engine mounting....it looked perfectly square on a glass surface and the main shaft just dropped straight in through the 3 bearings.....

Good going. Started to look like a heli now !

 Engine , clutch and cooling fan assembly mounted - 2nd Apr '10

All 5 servos mounted, cyclic bellcranks mounted, canopy also test fitted to get a sneak peek at the colour scheme... - 4th Apr '10

Torque tube fitted with both sides gear assemblies..Tail rotor assembled. Boom fitted to the main frame, muffler fitted, plumbing done...

Forgot to ask... did you get the 2 in 1 regulator ? Since you got a NiMH pack instead of the 2cell lipo, looks like you may not have it.

That is one of the best things I liked from Align.  Got rid of the whole glow igniter (hot-shot) business, with the convenient 15 seconds auto shutoff of glow power after pressing the button.  The initial units had some issues with switch quality etc, the current ones have been working great for all of us on our field.  Many have put them on non-Align helis, and even planes.

Here's one at about half the price

And Rotor stocks it too !
I am going to go with it for my Raptor 50

Anwar,
Since you used this, what is the recommended Lipo I should be using ? 2200mah 2S ? Thinking of using Zippy from HK

Some scary reviews (although with 5 star ratings ).  The output is 5.3v instead of 6v (this can be good or bad, depending on your needs).

Also, the Align one includes a 1900mah lipo in the price. 

Indeed some reviews were scary, where people reported loss of control when hot.
BTW Align one does NOT include the battery.  AMainHobbies says that clearly.
Rotor seems to stock these, and i would love to use this with my Raptor. What battery do you use, Anwar ?

Amain was the result of a quick search.  The last time I got one was from here :

http://www.helipross.com/align-b6t-2-in-1-voltage-regulator-combo-he50h11-1.html

and that is a combo with the lipo.

I use the Zippy 2s3p low-C ones (http://www.hobbyking.com/hobbycity/store/uh_viewItem.asp?idProduct=8272&Product_Name=ZIPPY_Flightmax_2100mAh_2S3P_Receiver_Pack_) and the Outrage XPRX ones (http://www.helidirect.com/outrage-nrgrx-2s1p-74v-2500mah-spektrumjrfutaba-receiver-battery-p-13176.hdx).  The Outrage XPRX ones also double as TX batteries for my TX in case of emergencies (otherwise the default NiMH). 

You can go for more mAH for longer periods between recharges, on a 50 size heli, the added weight is not really an issue.

Lavneet,
What servos are you using for your heli ? I remember you mentioning Hitecs but which ones exactly  ?
