Cman, What FBL gyros are you using with with your bigger helis?

I'll go for NEAGRON. Put a beastx in. They are very cheap here in the gyro sale section. For a long time I used beastx on all of my helis. Adjustment on the fly. No need for computer. For my level of flying (sport only), it suits me.

So, I checked my 300x. Like Lightningrc, the 3 links are of different lengths, lol. Must be the end of the shift when the manufacturing guy was putting them on. Even the indicator to 'face up" for the rods are not even done properly. 2 are facing down, lol. I'll go through everything with the heli once my fbl is here. Hopefully next week!

Yes but like I said the manual is even wrong it says all the servo rods should be set the same length .
It’s impossible then to set servos at 90 degrees then and the swash be level because the elevator servo is nearly 5mm lower !!!
I’ve emailed Align twice with no response and will keep annoying them until I get a reply .

Was this ever rectified? Or did you choose a workaround?

I bought some threaded rod from ebay and made a link the correct size.

What batteries is everyone using for these? I've got a bunch of 1300 25C zippy compact packs that are 110g from my 230s and 250cfx. The heli is a little tail-heavy with these - after adding weight, it seems to balance better with around 130g battery.

From HobbyKing, we have:

Turnigy Graphene Panther 1300mAh 3S 75C/150C
137g 74x35x27mm

or

Turnigy 1500mAh 3S 25C/35C
127g 73 x 33 x 27mm

Thoughts?

I'm using HRB 1300mAa 3s 45C 120g with XT60 although XT30 can do the job here.
Very good batteries, had great experience with HRB in general and the price is good.

Here's a couple of points. The links are pretty tough, but also pretty thin/small. I'm with you for bigger links.

But MORE importantly, they have two issues I do not like. The first is the difficulty of removing on installing a link on the ball. In some places (say the swash plate to rotor links) clearance is very tight on the bottom end. Hard to get 'em off, hard to get em on. The second is that the small threaded studs that screw into the ball link are, to put it politely, a pain in the ass. There might be an easy way, but I have not yet found it. I have a very tiny tapered bit for my dremel, and I use it (by hand only) to slightly taper the hole to get the rod started. I can't tell you how many times I have gotten it started, then have it slip and tilt to the side and pop off the shaft one more time.

Also one minor caution that just cost me a tail boom, feathering shaft and a set of blades. That rudder linkage uses a tiny ball screwed directly into the servo horn on the rudder servo. I was flying earlier this week and about 2 feet off the ground the thing went crazy spinning around. No control, hit ground, blades hit boom. etc. What I found was that the ball joint had come out of the servo horn. Horn had a split directly on the end. Of course, this could have been a result of the crash, but I suspect not because I was hovering rock steady preparing to land when the tail went crazy spinning around the heli. A video my son was making showed the carbon fiber pushrod flopping under the heli as all hell was breaking loose. Align likes to put big posts in small holes. That nylon horn is a bit brittle. Wish the shaft on the ball was a bit longer, so that it would come out the other side of the horn, letting me use a backing nut to hold it more solidly... I slightly enlarged the hole on a new horn, leaving it tight, but not that splitting tight. Hard to find the horns by the way. Part is DS4 which covers all the DS4 series servos, including all the ones on the 300x.

I agree. The tiny ball links and the underrated ESC are a let down on this model.

Crashed today. Tip over on spoolup due to a freak gust of wind.

The feathering shaft bent and the DFC plastic links shattered.

This heli really is a poor offering from align. If I had my time again I would definitely not buy this.

Esc not enough for supplied servos.
Tail servo mount allows servo to move.
Links are too small and shatter.
Cyclic links are too long, elevator link is too short.
Feathering shaft is too soft.
No support from align.
DFC blade links are so small they cant be adjusted - the plastic wears out after removing the link a few times when adjusting blade pitch.

I love my Trex 300x. Just got it a month ago and I fly it nearly everyday after work. Flys like a charm! Its fast, maneuverable and pretty stable in light wind. If the wind picks up it gets tossed a little bit but you gotta be quick with your throttle otherwise it can get pushed into the ground on a low hover. Mine is completely stock. I had a couple crashes already. One was hard. Had to replace tail boom, feathering shaft, and ball linkages. After that I had tail wag and vibrations in the main rotor too. Turned out the blades were too tight after I rei stalled them. Keep them loose but not too loose, where they barely can hold themselves up or from folding and you should be A OK! I think my next one will be an Align 500. Any thoughts on the 500 anyone?

If I was you I would consider the align 470lm, nothing but praise for this heli, it flies well, cheap parts, looks great, check out the 470 forum

Good grief,,, and here I thought all these weak mechanical issues was just me!!!
Every single one of these listed I’ve had/dealt with, too.
My latest, tail slider failed on takeoff. Hit t/told instantly, and another $100 to fix. 😔

I am so conflicted with this heli. I bought it to replace my old 250.
I love her when she flys, handles like a dream. However, Align cut too many corners with her substituting 250 parts instead of engineering parts to accept the forces a larger heli presents upon the system.

Got to admit, I’m sorry I bought her now, just because she’s fragile. If I had the cash back an OMP 2 would have been in my hangar.

That’s it, I’m fed up with this airframe!!!

Took her out, one last time, taking it pretty easy.
Second flip, dfc link broke, again!
This time the link just didn’t strip out of the threads, or split down the parting line, but broke the eye out.

I’m stripping this airframe of it’s electronics and will pick up an Oxy2 or 3 sport airframe. Will need to research which on will fit the electronics, but I’m not going to spend another penny on this pos.

You won't regret it! I have both and they both fly really well. I would think the Oxy 2 is a closer match, but I'm not sure how big the servos are on the Trex 300x so, yes, please check before buying either!

Well, she’s back together one more time.
However, I stayed true to my word, I didn’t spend a penny fixing it, had enough spare parts left to repair her.

Did find the root cause to the last crash.
Originally thought the dfc link failed in flight, but that wasn’t it.
I had a ground wire issue.

So, I’ll give her one more shot.
Like I said, I do love the way she flys. Like a 450 but snappy like my Blade 150s.

Won’t be able to try her out for awhile. After almost 9 days of 70+ F weather we get a cold snap coming in.

No progress as of yet. Still too cold for my poor ol’ knee’s. However, supposedly Monday we will get a break in both temperatures and low winds.

Did go against my word to not spend any money fixing her,,, sort of. It’s technically not a fix, but an upgrade.

Was placing an order with Boca bearings to replace the cheap ass’d bearings on my Blade 150s and thought what the hell, why not replace the same cheap ass’d bearings in the main shaft of the 300x? 🧐

During such I ran across another, shall we say, “deficiency”.
The main shaft of the 300x is 4mm, same as the Blade 150s, abet much longer.

Nothing I can do about that, but at least replacing the Align bearings with some decent ones should help out some.

Might end up looking into what I can do about different landing gear during the winter.
The Align landing gear isn’t the worst I’ve seen. Actually pretty robust until the temperature gets cold, but then it gets brittle.

Way back in the day, I replaced my old 450 and 500 landing gear with Gorilla gear. They are still on there, never an issue.
Going to look into it, I guess.

The links are the issue. They're just too small for this heli. The blade 230s has bigger stronger links and they survive brutal crashes. (But the 230s has a weak main gear hub).

Swings and roundabouts..
