Align trekker 800 lemon
For anyone even thinking of buying this lemon beware. It's a stretched 700 that has numerous issues. I have 30 or so flights on it and here's the scoop.

1. The OWB block is made of cheap aluminum. Not only did the OWB slip but the threads that hold the main gear stripped out on tightening! To make matters worse, the freakin replacement part (90.00) also had the threads stripped. Had to spring for 50.00 and buy the quality KDE replacement.

2. The stock white gears (mainly the main) started disintegrating due to the added torque of the pinion. The front TT and rear TT developed slop. Now keep in mind that Align has been offering " upgraded gears" at a COST! So to be clear, they identify a problem in their design but want to bang you even more money to correct their flaw....lol. Now mind you this is a 1800.00 kit!

3. The 700 sized head and dampers can't handle the loads. The feathering shaft sleeve is worn. I and others have gone through several sets of dampers with less than 50 flights! This should NOT be a PM item period. KDE is working on anew head as I type.

There is motor bog but I didn't expect scorpion performance. Now what kills me is that I have been reading how Align now (realizing the fact that you can't just stretch a 700 into an 800) is clamping that this is a CAMERA platform! Not so Charlie, the orig. marketing said camera/ 3d dfc performance. Even says it on my canopy.....lol.

Before you think about buying this thing, read the threads on other forums. I'm not just one disgruntled customer. There are others with exactly the same issues. There's a reason why the trekker 800 sales are dismal. Oh, I forgot. You can't stick small 700 size skids on an 800 either unless you want to use up the inventory of the 700. For 1800.00 we should expect more. I should have listened to my friend and got a Diablo or TDR. Buyer beware!

That's helpful.

I must admit, I have been tempted to buy the Trekker with some of the deals I have seen. Getting into an 800 sized electric for $1600 (Best deal I could find) seemed to good to be true.

I appreciate the word of warning and feedback. Still not a bad deal, but needed upgrades seem in order.

Thanks

I recall seeing this kit in person and thought wow what an under developed kit it actually was. IMO it looks a like a Trex 700 V2 with a minor frame change and a longer boom and that’s it. I would NEVER EVER strap high end camera gear on this bird. Good luck hopefully it will all work out sorry you are a “beta test customer” but with Align it happens all too often.

Ugly can be fixed stupid is forever!

Be aware that the 800 isn't going be be that great for tight 3D. From talking to some of the pro's, the 800 is great for big air, but not so great for tight 3D.

I'm about 1/2 way through my trekker build now.

1. I took apart my spraque clutch housing (OWB) and yes, stripped one of the bolts in the housing when I put it back together. It appears as though it was drilled too big before the threads were cut into it. I'll contact assurance and see what they have to say.

2. I did end up buying all the new delrin gears for this heli which should have been provided IMO. I will leave the stock white gear in for the initial few flights to see how it holds up.

3. Same with the dampers. I'll use the stock ones and see how they hold up for me. I would anticipate some aftermarket companies to step in and provide a more durable damper system for the trekker.

I don't know that this warrants calling it a lemon. I would encourage anyone who want to know more about this heli and Hidaven's issues with it to go read the trekker thread on HF. There is more information about what he and others have gone through there.

I would agree with that. If you want tight pop/lock performance get the 700DFC.

Lemon
Wait until your dampers start loosening up after 15-20 flights and need replacement, and your feathering shaft sleeve loosens up. Bearings are also wearing quicker in the grips. You can't put known inferior gears in an even bigger heli with a good conscious. It's criminal as this bird can kill. One should not have to replace the entire drive, and do all the other mods before the first flight.

We who pay good money deserve better and unless you take a stand these companies will continue to get away with this nonsense.

I also hope your strapping on some aftermarket quick UK large skids as these moronic undersized 700 skids are much to narrow for the 800. Ground effects are much more pronounced.

Oh, and lastly lets not forget the cc120 is still having issues. Couple of the latest v2s caught fire. Most of us had to upgrade to the 160. My term "Lemon" still stands.....

Keep in mind I'm a sport flyer! Imagine the toll 3d will take on this. And regardless of Aligns nonsense current claim that this is mainly a camera
Rig, it sure as hell wasn't marketed as such. My canopy says 3d DFC.

You don't sound too confident in your speech and you are already buying upgraded parts. You are also already experiencing issues and still in the build process. Sounds like you are already heading down the lemon road. I would be interested in your feedback after you get some flights on it.

mikado logo 800 xxtreme $2,679.99 (designed from the ground up for 3d)

TREX 800E Trekker DFC $1,828.00
Features of the Trex 800E Trekker :
● Designed specifically for aerial photography and cinematography. The long 800mm main blades provides superior flight stability and high payload capacity
So basically they are saying that it isn't a 3D heli.

Good Money!

Not to be a SmartAss, but for an AP platform that is not good money. Get a Mikado 800 bare bone kit and go from there. You need a dedicated machine. Design your own frames and use mikado 800 parts.

Trekker 800
Here are a few flight from guys like you at the field flying and having fun. Yes there is general maintenance but I can tell you these 800's were flown with stock gearing(white main gear), dampening and autorotation units.

Watch at YouTube

Watch at YouTube

Or as a Gimbal mounted Trekker 800

Watch at YouTube

In all cases these are stock helicopters with no modifications.

Have a great day.

So, are you saying the gears, one-way and rotors are over-designed on the 700?

I'm a fan of Align. Fantastic breadth of products. I own many and will own many more. But this one does seem to be a stretch (pardon the pun).

The one way thing does seem to be just a QC issue. The hardened sleeve should be a tight fit in the bore (don't just rely on glue as it breaks down under the loads here...reduce the gap and you're not relying on the compressive strength of glue anymore. )and it seems a lot of parts got out with bad threads. Hopefully that'll be fixed soon. Looks like a good design if done well.

I don't want to make any judgement on the heli until I've flown it. I'll be in a position to call it as I see it after a month or two of flying it.

I will be doing more aggressive sport flying / light 3D

I read all 5 pages and all the bashing threads are mainly from you LOL.You started bashing it BEFORE ya even had it.You didn't have the heli but yet trash talk the heck out of it .Now you have it,you nit-pick everything thats not made to your liking..
The ONLY thing I see being a issue is the one-way,thats it..Send it back or upgrade and fly it..
When the sleeve gos bad,its because you flew with bad dampers too long.."IF" the dampers went bad that fast,you should of upgrade which is only a few buck more other than keep buying them..Thats your problem if you bought a bunch of sets knowing they don't last..If I went through a set of dampers with in 3-5 flights (thats exactly what your saying),I would of spent $3.00 bucks more on a different set.

As for bogging,could be setup which noone will ever know..Too much pitch,VERY poor collective management,crappy lipos,crappy gov ect... .Are you even running gov mode?I could bog the crap out of my 700N with a flat 100% throttle curve but not running gov mode.Setup plays a HUGE roll...

Thats normal for the main gear..Whenever I put new main gears on (every brand I owned) after stripping one from a crash,the mesh loosens some after a few flights...Even after 200+ flights I still get the dusting on the frames from the main gear

The only issues I see is the one-way,thats it..Sometimes a bad batch of parts slip by which has and still does happen with all brands from time to time..Some ALOT less because they don't sale as fast as Align....

Just shows this was ment to be a bashing thread because you already bashed the crap out of it before you even bought it...Why in the world would someone buy something they didn't like before buying it then turn around and buy it ??
Buy a set of different dampers,sent the one-way back or upgrade it and fly..If your going to complain over nothing,sale it and move on..

Ive seen and read jschenck's post all the time so would rather see feedback from him other than someone that bashed something before even owning it..

3d isn't always tight fast stick bang stuff...my AP heli does piroflips at 1200rpm...

The requirements for a good AP heli are simple: lift, no vibes, land in one piece

....the details of achieving that are not simple, but I almost ordered a Trekker when I saw the way it was done, and I am big heli snob.

You have to put harmonics and practicality ahead of 3d performance in an AP heli. A stretched 700 is better than a 3d 800 any day.

the xxtreem is too rigid to dial rpm into the sweet spot for certain cameras and blades without throwing more weight on to find a work-around. the trekker is a good solution for 800e AP.

OP, you need to fly that thing like a helicopter: 1500rpm, bigger moves, less pumping, tic tocs, banging...it is a casual sport 3d / AP helicopter, not a 3d heli like what you guys call 3d now Or just give it to me!

Lemon
All of us who own this thing have had to replace the OWB block. It slipped on a bunch of us and the cheap aluminum material keeps stripping out when tightening the bolts from the main gear.

As stated the cheap white gears are wearing quickly regardless of what videos the Align reps posts. Ask that guy why they came out with the new black ones then?? Never can get a answer on that. And why they decided to put them in a bigger more powerful heli AFTER they knew they were having issues with the dfc 700? Can't get a straight answer on that either.....

+1 on the logo recommendation. For the rocket scientist who said I'm the only one, go and read the posts from Helifreak and you will see posts from a pro builder nu66ie that reported this crap before I took up the cause.

No one should be doing this kind of modifications with this few flights. What in the world do I have to gain here? I'm pissed that I out of pocket hundreds to get this safe and durable. I also have a trex 550 with no issues.

This heli can't take the additional SUSTAINED power of the bigger blades. My friend changed his dampers 4 times already! It was a 700 sized bird stretched to an 800 which was a bad idea.

Now if you want to disregard my findings and others experience go buy one! I'm just letting folks know that there are issues that Align has chosen to ignore. Not replacing these gears out for folks and/or not putting them in an 1800.00 kit is insane. Do your homework and understand that as stated, its better to go with a properly designed 800 then cheap out and buy a stretched 700 especially with a potentially lethal machine like this.
