Align T-Rex 450/470 104T-28T Autorotation Tail Drive Upgrade Set

This is a great upgrade for the Trex 450. The tail seems to blow out slightly under pitch pumps using the Standard set up that comes with the kit, so this definitely helped. Is this condition a lot.

Quick shipping as always from HeliDirect. Haven’t had a chance to install this yet still waiting on some other part that have been on back order for a while. Nice upgrade with all the parts needed. Would definitely recommend switching the skids out to the 470 skids for better clearance on the tail.

Great upgrade

This is one unit that I have not seen a single "critical" review on. Well I purchased one to try and have 2 identical 450 DFC setups that should provide a good side by side comparison vs. stock. My 2 helis have always been slightly different in that one is 100% Align (except for servos) and the other started out a Tarot. However now they are identical except for the ESC. The heads, blades, FBL unit, servos, motors - all the important stuff is the same. The frames, bearing blocks, and tail case are slightly different, again one being Align and the other being Tarot but the performance of those items is identical. The gears and bearings are Align and FastEddy respectively. But this is starting to sound like a review of my helicopter which is not my intention.

My point is, if anyone has real word info about this parts kit - please share. I am currently building a 470L with a friend and building a 450L for some side cash. As soon as I get those wrapped up I will put this kit in one of my models and let everyone know what I think. Both helis fly exactly the same and have no issues with vibrations, tail blow out, overheating of electronics. And I time my flights to 5 minutes mostly on 95% throttle and my pitch is set to about 10-11 degrees.

My confusion lies in that this is sold as an upgrade. I know there has been issues with the 450 tail given the Dremel mod and grip flip mod. Is this supposed to be a fix for that? My concern is that the tail blades already have minimal ground clearance on the 450L especially. This extends the blades a few extra mm so may be a problem. Just FYI - I did the Dremel mod even though I wasn't having any issues. Even if I don't use the extra travel provided in flight it is nice to know I have it available.

I like the combo pack. It was all the parts that I needed in one pack. I also found the price of this combo to be reasonable.

Not a fan of Align electronics, but now that they are including the Microbeast, and HW rebranded esc,.. I'm much happier to purchase the Combo kit! The complete kit being around the same price as a set of good servos, how could I pass it up?
