started building my terx 450, the kit is bought from our forum member GE,the head assembley is  almost fininshed,servos installed and everything is working in the right direction.I know the toughest part is yet to come, when setting in the tx and gyro. but i am sure i can finish this with the help of the helipro's here


few pics

Coooolllll......

Coming up nicely :thumbsup:

How about some test flights on the little one !

Looks great :thumbsup:
All the best... {:)}

Hmmmmm, Alllliiiignnnnn, Yummy!  (:|~

waiting for my hd cam,not interested to spoil the beauty of little baby (trex 250) flying by shooting on a mob cam

do you think the build is so sweet for a beginer ;)

 :giggle: No Not at all, Its a crazy Torque drive, you land a lil hard and it breaks the umbrella gears, and u will loose the control of the tail. NO NO for a beginner. If I was in your place I would have ordered a HK 450 MT (around 40 USD + shipping), transferred all the Align electronics to that and learnt on that first, till I atleast learnt Forward flight.

Anyway, the Yummy was for the Align Quality  ;)

Anyways all the best, May God bless you with 0 crashes!

Just leave the tail blades liberally loose (so that they can fall on their own weight), and it significantly reduces the risk of torque tube gears breaking on tail impacts.  Other also extend the vertical tail fin with contraptions like thick piano wires, so that the chances of the tail blades hitting the ground are minimized.

I had added an extra tail support to minimize tail blade touch to the ground  ;)

finished the tail assembley.loctited  everything.any idea how to remove the feathering shaft to put some grease on it :help:

You will need to use 2 hex/allen drivers, and hold it together from both sides :)

If u still feel its tight (loctited), dont bother opening it further until u apply slight heat on the screws using a soldering gun to loosen the loctite.

Most importantly, remember to tighten it well using two drivers and some blue loctite, otherwise you end up with this (around 0:30)  ;)

santosh.. this is a great heli.. if you are a beginner try using the training set for few flight and yes the risk of stripping the TT gears are high but again you will be really happy with this once you learn to fly if properly... i have sent a set of CD's to ANTA on the forum on setting up a align heli... if possible try to get a copy of this and this might help you on the TX settings...

thanks sujju,will try to get a copy from anta

After inspecting my HK pro closely, this Align Pro from the pics looks much better built.

HI santhosh,

can you pls give me the conatact number of the Buyer from where you bought this 450 pro heli.

Regards,

Hi Santosh, hows ur birdie doing?

it's not finished yet, i will post the pics when i start again

hai all
  just finished my heli today,i was able to hover it nicely.when i first tried two days back the tail was turning to one side always,it took two days to find out the cause, the rudder and the gyro direction was reversed.now its ok,the next problem i faced after correcting the tail issue , the heli is lifting only around 3/4 of throttle ,played with pitch curves still its lifting around half throttle,so  all the heli gurus  here i need your help,no idea whether to play with the head speed or pitch.thanks a ton for sujjju for the setup cd and anwar bhai for the valuable tips in setting the tail linkage ...see the pics and videos

i dunno about your gearing so throttle curv i can not say anything about but if it hover steady it is probably ok for now

pitch curve depends if u want to fly inverted in the future or will b happy with stall turns loops and rolls.

if u r happy with the simple stuff u can set pitch curve so it start to lift at mid stick, quite common in germany to do so,

if u r planning on trying for inverted and 3d learning where center stick is is very important and then i will recommend linier pitch curve
atleast from 0 pitch at mid stick to full pitch

if it make sense?

@Santhosh: Nice hover  {:)} and nice bmw too  :thumbsup:
