How Do I Repair an Align?
So I'm pretty new to Align. They've been around a while but it took me some time to buy one. I have a 700XN. It's been a maintenance free experience. Nothing has worn out and I haven't crashed it. I haven't need parts - until this past weekend.

Last Sunday I had a small "mishap" and I find myself in need of parts. Any other model I'd look up the part numbers in the manual and type them in at AMain or HeliDirect or any other number of online hobby shops.

Thing is, I don't see any part numbers for this model in the manual. Furthermore, if I go to Amain and Type in "700XN" only a small fraction of the parts on this model appear. For instance, searching "700XN" doesn't pull up a boom and torque tube. I assume these parts are common with a previous model, likely the 700N, but is that common knowledge?

Until this weekend I had 4, 90 class helicopters - 2 X-Cell Tempests, a TSA 700N and an Align 700XN. Each has it's purpose in my helicopter world. The Align is included because it is still in production and you can still get parts. I never thought I'd have this much trouble finding the parts I need.

Someone tell me how to fix this thing.

I can't answer your question, but I assume you're going to fix it? Perhaps, you're waiting on the outcome of this post to determine if you're going to fix it? Either way, I'm interested in what others have to say.
wjvail I don't see any part numbers for this model in the manual.
Wow. Really...that is kind of messed up. I'll fess up and say that I've never owned an Align, so I didn't know this.

Good luck, Bill.

Well possibly I'm missing something. I know of that store. Following the link you provided I clicked on "Align Parts". I then clicked on "T-REX 700XN Parts." There are two pages of parts. I need two lower frames (among other parts). I defy you to find them on the link provided. Going on, I see 4 sets of "landing skids" and "skid pipes". Which came with my kit and why are they all out of stock?

The parts listed on this site appear to have part numbers but because they aren't in the manual, I can't search for them.

This can't be this hard. I must be that stupid.

Thank you but I don't see any boom hardware (boom, TT). Again, I suppose these items are common to some other model and with a part number I could confirm that.

Using the link provided I don't see the aluminum frame brace. Surely this item is specific to the 700XN. Mine is bent. I don't see it here.

Man I love this site and the people on it. Thank you for the link. It is exactly the information I needed. I have a box of parts on the way.

For those in the same situation as myself, I found (almost) everything I needed at GrandRC. http://grandrc.com/ Using the link provided in the last post I copy-and-pasted the part numbers into GrandRC's search box and was able to find all the Align parts I need. Everything was in stock. The only bits I still need are non-Align pieces I knew were going to be hard to find.

Anyway... Thank you for the link. It changed my opinion of this model.

Bill

Hey Joey... Sorry it took a day or two to get back to this. Whatever I thought I was going to work on this week has changed into getting this wreckage off my work bench. I'm a little behind in my posts.

For a long time I was torn as to weather or not I would repair this model and if I did repair it, should I just buy a new kit. They are in stock and about $900USD. This option would have several advantages. First of all, I would have all new parts. That would include blades and canopy. I also would not have to bother with putting together an order of individual pieces. Given that I was having trouble figuring out exactly what to order, this was no small advantage.

Down sides would be that it's about $900 and I would have a lot of extra parts. My mishap was odd in that a lot of things you might expect to be damaged, weren't. The tail rotor assembly is pristine. That includes blades and gears. The head is undamaged to include the main mast and spindle. The main gear and auto hub are undamaged. The (in)famous 700XN gearbox is undamaged. In fact, had the clutch not exploded (and subsequent fire), I might have been able to fly the model within a few hours.

The other down side to simply buying another 700XN kit to use for parts is that, if I'm going to do that, why not try another model? Why not a GloGo kit or Synergy?

Another option was to simply park the model, sell off the good pieces, and reduce my 90 fleet by one. As you know, my other 3 90 models are much harder to repair if damaged. The point of the Align is that it is modern, still in production and parts support is easy.

Eventually I decided to repair the model I have. The link posted by chopper37 and the 100% availability of parts at GrandRC made the decision much easier. My order was about $500 but includes about $100 in parts I don't immediacy need. Of the remaining $400, $120 of that is blades*. That means the real cost to repair this model is something closer to $280. Again, with easy access to part numbers and the one-stop-shopping at GrandRC, it was pretty painless.

The model isn't repaired yet so I reserve the right to regret my decision. Once it's sitting on the skids again and had a few flights through it, I'll know better if I made the right call.
------------------------

* I have other blades around here but I liked the Align kit blades. Rare to find 700mm class FBL blades that are 180 grams.

I think the cost is OK. I just had something similar to your crash happen to my JR Vibe 90SG. If you think parts are hard to find for your 700XN try the Vibe 90SG. For this crash I had parts coming from UK, China, Japan and Greece. I spent a week with Google Translate finding parts from places and a month waiting for them to start showing up. By comparison finding parts for your 700XN is nothing but an hour of web browsing and a 4 day wait for parts. Its all relative

Bill, sorry to hear about your XN "mishap". Why do you think the clutch "exploded"?

Probably did the chicken dance and it eventually overheated the clutch and it exploded. Been there done that.

JLF92677 Bill, sorry to hear about your XN "mishap". Why do you think the clutch "exploded"?
Hey JLF... I never like crashing but in all honesty, I was probably overdue. In the case of this crash, I'm not exactly sure what happened. All I'm certain of is that I lost radio contact with the model. The model stopped responding to commands. It eventually settled into a disk-level rapid pirouette and fairly slowly hit the ground. I pulled both the engine cut and throttle hold before it crashed but neither had any effect. The model hit the ground at 2050 head speed and, surprisingly, wasn't too badly hurt by the crash.

Unfortunately, the engine continued to run at near full throttle. The model didn't "flop around" but the combination of an OS 1.05 on 30% nitro with a new Lynx heavy-duty gas clutch was never going to end well.

I knew when it hit the ground things would end badly. I jogged the 100 yards to the crash site and pulled the fuel line. By then the aluminum clutch bell had turned to plasma and the clutch itself had broken the frames. Pulling the fuel line effectively killed the engine but it also vented the tank and by then there was enough heat for the stream of fuel to ignite. As before, there was surprisingly little damage as a result of the fire. All servo, receiver, FBL, etc components appear to be in good shape.

That leaves me trying to figure out what happened, why and working to repair my model. The good news is that the repair was really straight forward. As I said in a previous post, using the online parts diagram to look up part numbers, and the availability of ALL parts from GrandRC made that job simple.

As for finding out why I lost control, I can only guess that something in the power delivery to the flight control system came unplugged. The receiver battery was dislodged from the airframe in the crash and in being ejected, pulled all power connections loose. The connector was pulled from the iKon and the LiPo was disconnected from the XT-30 plug. Furthermore, the only thing really badly burned in the crash was the switch.(!) In short, anything that might suggest where or why power was lost, was damaged or disconnected in the crash.

Another possibility for the crash might be that there was some problem with the FASSTest set up. I had just installed a Futaba Temp probe and was using the SBus-2 port to record and send engine temperature data. There is some very curious damage to the temp sensor. I've begun to wonder what happens to the control system if a telemetry probe fails? My understanding is that the telemetry data is "mixed" between the flight control frames being sent to the receiver. I'd like to believe if the probe fails, the flight controls will continue to function - but I have never read anything to suggest such is the case.

Anyway... The model is back together and I'm just waiting for 2 new antenna from Futaba (mine were singed) and I'm trying to find a new switch to my iKon (which is proving to be frustratingly difficult.. i.e. impossible.)

Hi Bill,

Thanks for your detailed update.

My thoughts: I think you are right to assume that the power delivery failed in flight. I say this because assuming that you had programmed the engine fail safe (F/S) condition to go to idle if radio signal is lost or low battery condition, the engine would have rev down to idle if onboard radio power was available. Now, I am not familiar with Ikon FBL unit, but I would assume it supports Futaba F/S mode. Based on your update, it is difficult if not impossible to determine if the battery power connection actually came loose in flight or the power switch failed as it got burned.

Suggestion: You probably done this already, but I would check that F/S mode works for both loss of radio signal and low battery condition. I believe you are flying 18MZ radio. So you may also want to check that when you link your receiver you set the B.F/S voltage to the proper voltage level for the battery chemistry you are using (2S LiFe 6.0 - 6.2V / 2S LiPo 7.2 - 7.4V) as the 18MZ default value when linking receiver is 3.8V for NiMH and NiCd which would prevent F/S to work correctly if using LiFe or LiPo battery.

Sorry again to hear about the crash, but at least you were able to get it fixed quickly.

Best regards, Joe
