7HV Issues (!!!)

[Sebastian Zajonz]

Hello Guys,

I don't know why so many well known problems seems to be unknown for the US customer but I want to make some points clear.

First point. Assembling line from Compass did not add the second canopy mount for the front to the kits. We will send some asap. We informed all EU customer about this on the very first day and send this information to all distributors. Don't fly with canopy without this second canopy standoff. This standoff will be assembled to the frame right over the maingear - the canopy can never ever touch the maingear with it.

Second one. Some 7HV motors has isolation problems. We did an video and a text to inform all customer to check their motors. Compass replace destroyed ones super fast. In Germany we allready recieved the new ones. Reason for this isolation problem was the paper we used for isolation. We changed it and the new one is super strong. Hard to cut - even with a knife.

3th point. Belt rubbs the maingear. This is cause by the aluminium mount of the belt tensioner which has in some (under 10%) cases a thread which is not in perfect 90° angle. Please contact your dealer. Compass will send new ones.

4th point. Missing parts in the kits: pin for batterylock (from rc-cars well known) and a shorter bolt for tailclamp - will be send to the shops and distributors.

5th point. The blade company send us wrong blades. We only checked the examples for weight and flown it in all prototypes - with perfect results but they send us F3C Blades with a high weight (215-225g) and more flexible for the kits. We didn't know that and missed it to check the weight. Ask your dealer how to manage this. Flying with the F3C blades should not be done in 3D flying style because the CG is far outside and the weight super high. In worst case and especially with low RPMs this can cause a Boomstrike.

Maingear is not from Odin - Thats another one and we even tried it with 9000 W motor. Could not break it in the air. If one single theet is stripped its most likely to small mash in the gears. It is important to have some slope there and use some good grease to reduce wearing out the gears and noise!

We apologice for all those unnecessary problems with the first lot of helicopters.
This helicopter kit was not finished for customer - because we missed to check some points. We do our best to make every user of the first lot happy with this awesome machine.

Thanks
Sebastian Zajonz

Thanks, much Sebastian. This is why I fly Compass!!!

[oxylos]

Wow...thanks for the impressive clarification

Now i can wait releaxed for the next charge.

Thanks for posting clarifications Sebastian.

At least the issues are being brought out in the open. I'd much rather have a manufacturer admit they made mistakes and quickly remedy them than to sweep the issues under a rug, which seems to be an aCCeptable practice for some manufacturers.

EDIT: This is an important bulletin, so I made it a sticky, at least until such time as the affected units are taken care of.

That's a good throw in, I like that.

Good call on the bulletin. I agree 100% about getting the issues in the open, I am very glad this was done.

Nice to know.

[kevinator9]

Good to see the summary.
Teething problems on a new models are always going to be present. Especially on pre-production kits. At least all the problems are well known and all of them are being rectified.
I would just like to add that for point 5, Nankin Hobby is sending out new Mavrikk 690mm blades in exchange for the Compass 690 blades. Props to Nankin!

so for the second lot every issue for 7hv will be fixed? or still the same?

[skunkworx]

Well, I guess you can't get all the bugs fixed right out of the gates, but at least they weren't hiding anything and responded quickly to everyone's concerns. I know that these explanations will help more than a few guys rest at ease, but probably will leave a couple miffed. It definitely wasn't intentional. Thanks for your patience in either case!

[jstnt]

is there any blade replacement from compass for wrong blade?

[blackcataps]

I had a kit only on order from rc711 and although it took them a couple of days they had stopped sending kits out as soon as they realised the issues and have sent notification to customers saying so. It now appears there will be a 2-3 weeks wait for the second batch of issue free kits? I hope so anyway? One thing in support of compass is at least they admitted the faults. I hate it when companies try to bury issues(are you listening Spektrum Horizon Hobby?)

I like my 6HV a lot. I have been watching this product launch for months trying to decide on what I will buy for my second 600/700 size heli. I'd really like to agree with the majority here and say, hey not a big deal. All product launches have problems. However IMHO, this launch has been both disappointing and disturbing.

What was the big rush? Delivering kits to the general public without manuals, wrong and missing parts and parts that are not manufactured correctly is NOT OK by any stretch. Five different and significant issues is way too many. While I applaud the speed and candor Compass is showing to rectify these issues, the bottom line is that doing anything other than that would have made this launch a complete disaster.

I have got a 7HV on pre order and must say I'm now glad I didn't get one in the first batch. Although I partly agree that a plain box without graphics is no big deal and yes I put most of my boxes in the recycling bin I still think how the kit arrives sort of sets the scene. So ok you get a plain box,so no biggy but then find no manual. Ok, again not a biggy but I for one would find the build a lot easier with one but onwards and upwards. Then when you have built it you find the canopy catches and is damaged by the main gear and because you haven't got a manual you don't know the canopy post are missing. Then you find the belt is catching and if you bought a kit with blades and motor that both are at best unsuitable and worst motor packs up and you have a damaged 7HV.
So as much as I'm a BIG compass fan I find the 7HV launch a strange one for a company that in some parts of the world needs bad publicity like a great big whole in the head!!!!
So having spent so long testing the heli it's a shame this has happened.
I for one will still leave my order in place and hope that compass get their act together with the 2nd batch. However I'm not overly confident. We shall see????

[BakedMopar]

The kits DID cOme with a manual. At least mine did. There is no mention of canopy standoff in there. To me its the gamble you take when ordering a new release in anything. It's just the nature of the beast. What bugs me the most is we put castle down about them blaming the user and here I read that my gear is messed up because of wrong gear mesh. Lol.

[Ah Clem]

I am still looking forward to getting mine.

As far as the manual goes, there is a revised, more detailed version in the works.

[Rob43]

I don't mean to be persnickity, but I am concerned about the motor. I can remendy the tentioner perpendicularity, new blades and standoffs are on the way, but are motors being replaced with ones including the heavier isolation paper? I'd rather err on the conservative side with the motor so as not to have an "unplanned event". I am content to await the parts so it's right at maiden. I am flying my 6HV without issue, so I can wait for the parts.

So that's great but why is it in the works? Why wasn't it ready at launch? I agree that when you buy a new product you,to some extent, become a product tester (remember the iPhone with the iffy aerial that if you held it wrong dropped all your calls?) but no manual and missing parts? The wrong blades and motors that are faulty? I don't know perhaps it's just the way things are these days. When I think about how many software updates it took to get the DX8 right and in some cases caused people's helis to go into full negative pitch and smash into the ground! Some would say the DX8 is still not right(gimbals for one).
Still looking forward to getting my 7HV.

I'm glad I waited on my 7HV. That being said, this is a very common issue with Chinese manufacturing. At least it is in the business I am in. I work with a company that makes small consumer electronics and they used to make electric lawn and garden tools. Regardless of the amount of information given to the factories, they always ignore details imperative to the process of making a product good and then they cheap out on parts after the prototypes are done. I have seen this from 6 different factories in China. Maybe it would be the same way if it was made in any other country, I don't know. But I can tell you that what just happened with the 7HV happens all the time, and in many different product categories. I'm actually surprised this happened to Compass since they are able to communicate with the factory in their native language. I just thought it was a language barrier.

I think your making a big deal out of little things in some of these cases.

It was posted here (as well as many other places I'm sure) that it would not include a full manual.

I for one am glad I have my kit, not sitting here because the manual isn't finished and the box isn't pretty.

The motor and blade issues are just that, stuff happens. Could it have gone better, sure, but it also could be a LOT worse. (DX8 example above is one). I for one am not worried as I know Compass and Nankin will take care of me.

If you DON'T have a kit, I don't even know why your posting about this, just sit back and wait until the final few bugs are worked out and get yours, what is the problem?
