I haven't flown it yet but if my TREX 700 flies as good as it builds it will be the best heli I've ever flown.
In true Align fasion, the TREX 700 is a very easy build. I only had one issue and that was the primary tail control rod carbon tube's hole wasn't big enough for the ball link rod. Beyond that, I think I could have just shaken the box hard and it would have gone together - by far the easiest 90 I've ever built.
A lot of neat design choices - the pics don't do it justice. It's a very sturdy model.
The canopy grommet design is the best I've seen yet and of course the canopy is beautiful.The fit and finish was great, 10/10 imho compared to other models.
I wasn't sure if I would like the "look" of the model but it definitely grows on you as your building - there is nothing that wasn't thought through. A good example is the blade grips fit to the head. On most models, you can't rotate the blade grips 360 degrees and if you did something would be scratched. There's almost unnoticeable groves cut into the head to allow the grips to slide through. Little things like this throughout the model.
The fan design is slick, very innovative, I like it a lot.
The new shimming method to get your main gear mesh is also very innovative.
This model leaves almost no room for guest work which I like.
The fuel tank is massive and I appreciate the thought put into the design with the extra hole cut for my pressurized fuel delivery system.
All of the parts are very high quality and everything fit perfect. I keep saying this because it's so rare to get a model that the parts just "fit".
With the "boxed" mainframe design, it should crash well.
I haven't weighed it but compared to my Synergy it's very light.
The entire build took 6 hours. This included my engine and servo installation. Radio gear took another 2 hours. I consider myself an above average builder (yea, I crash that much, lol)
Things I would have liked different: I would have liked a thicker or graphite tail control rod. The radio gear tray, although very spacious, could you some more thought. There's no clear way to mount the battery and no easy way to run straps for securing gear. I would have liked less "rounding" of corners in the head and bearing blocks and a more industrial look (personal preference, not a flaw by any means).
Another build note, if your tail control rod seems a bit short your tail shaft isn't in all the way, there's about another 10mm left in there when you think you're meshed up with the gear box. Gently tap on the metal tail box to get it in the rest of the way and everything will line up just fine.
If you have a YS91-SR it fits perfect just make sure you use the outside hole on your fuel tank for the clunk. The inside hole puts the fuel tubing at an awkward angle that I didn't like.
I'll update this again when I finish with the head geometry but the book lengths look pretty close.
Kudos, Jason Kraus, another fine design, great job!!!
