Looks very nice. Let us know how it flys compared to the Eagle 3.
I was a Hirobo fan but have been adding Aglins to my fleet as of late.

Thanks Buz.
The Hirobo for F3C it's top of the art with much expensive parts.The ALIGN it's best value for money heli choice with cheep parts and I thing that he fly very good for fai style.I see in building some wrong with some parts (something that you don't see in Hirobo also and in cheep models like sceadu) like the elev servo base that he stuck in main shaft bearing base like you see in pics but this is not problem.

Align Dominator 700L TOP
Hi Nikos, like you I was also flying Hirobo Eagles in the nitro age. My last F3C Worlds was 2007 Wlocwavek. Now I am trying a return, this time using Align as it is much or affordable. I have a choice to purchase a Dominator 700L or a Dominator 700L TOP. Is it possible to tune these for F3C? I am not a top level pilot and I merely aim to make a decent showing. I am satisfied with just being able to complete the schedule and hopefully finish at least bottom third. Thanks!

Hi.I dont think so to flying well f3c because its direct system.(servo to swash direct move).The best choice (my opinion) its the push pull system not like dfc.This its best for hovering because the heli fly stable and its not very agressive in stick move.In upstears (idle up) you dont have major problem with dominator.The issues its the hovering.(This is my opinion).Hirobo SDX D3 Fbl - ALIGN T-REX 700 F3C V3 FL HEAD-ALIGN T-REX 500 DFC

Hi again.
After a year and more I decided to make some upgrade to my heli for next year F3C contest.
The parts that I go to upgrade is the tail from 2 blade to 3 blade,the tail gear ratio with new set from Align 105t,the canopy from DFC to new one 760x and the pitch arm F3C from 760x also.
The canopy I decide to change with new one 760x because I don’t see it well upstairs.With the DFC canopy the only see is shadow.
Next one the 3 blade set and tail rotor from Align.
Because in hovering mode I have 1500 rpm I want better tail for hovering.Also I want to speed up the tail rpm so the better choice the new kit with 105t from Align.
The problem that I see is the motor pinion gear mount.Because the second gear have 2 teeth more from older gear...the gear it’s bigger a little and he stuck into motor pinion gear mount.I see that the Align have the new code part that it’s not straight but have a little curve to make space for second gear.So this part I have to wait to come from order....
Next part that I decide to change is the pitch arm.
I go to new F3C pitch arm from 760x.Some issius also with that because with everything level and the sticks in midle without curve etc with the lingage that he have inside the set from 760x a have negative pitch and he don’t go in center (measurement mechanical with blade holder mark).
So I test it with older lingage that I use with other pitch arm (stock efl head) to go in center mark blade position.The older lingage is bigger.
Tomorrow I put back the blade and I use pitch cauge to see where is it.
Anyone make the same experiment with that parts or I am the first?
I’m wait to see how he fly...
Enjoy some pics

Everything is ready and I. Waiting for weather to test it.
The last upgrade parts is the skid. I put the skid from blackshark that it is inside the f3c blackshark body. Is very low and it's beautiful. The issue from that skid is the rear vertical fin that he have contact with ground.
The solution for that is the two cross member into rear side skid to give a little high in tail (like 760x).
I need to thanks Dr Ben for helping me with the cgy 750 setup for hovering optimization and Mr Ander Stålis.
Enjoy the pics below.
