Deal Extreme parts

Hi,

I have received my Deal Extreme parts and I concur with the assessment that they are not really worth buying. Unlike other reports my inner shaft was perfectly straight but that is about all. The bearing on the swashplate is dented making it useless. The blade holders do not align properly so you can not get a good assembly of them. As reported the balls for the ball links are just a hair bigger and in my opinion unusable. Another issue is that none of the parts will work with the stock parts as they are all of different sizes and alignments. That said, a person with handy with a micro-file could make the blade holders work with just a little effort. For me it is a total loss as I broke my swashplate and a blade holder and I had really counted on being able to use the new ones. As I said, taking a file to the blade holders would get them in shape but the swashplate is another matter that I dont see any way of fixing easily.

Later,
Jon

Thanks for the report Jon.

Anyone buying these parts, please go back to the Dealextreme page these parts are sold on and right a review warning others of the risks of buying these, apparently crappy parts. Prospective buyers put a lot of weight on those customer reviews. At least I do.

You can unwrap it carefully and put it back together w/out any damage really. If I recall correctly, there's some foam pieces that are stuck here and there but they're easy to deal with. I actually removed the wrapper from mine altogether to save a few grams of weight (3g as I recall), although of course it does make the unit a bit more vulnerable to damage that way.

If the 4in1 I had for sale is not taken (see previous post), I would gladly donate it to the effort of finding a way to hack get signals out to brushless ESC's. If it survived the process I would like to get it back. Now who has a scope and skills for the task? I understand there can be no guarantee of success- but I'd put the 4in1 at risk to give it a go.

That does sound like a fun project. I can't even consider it for the next three weeks, but maybe if no one has stepped up before then... I've never done something quite like that, but I do understand the theory.

Strange, I got my Deal Extreme package and installed it a few days ago. Yes I did have to slightly polish the centre shaft with 400 sandpaper. The swashplate was a little tight but some 3 in 1 oil and working it to the extremes for a few minutes solved that.

I used the stock blade holders as I have heard in both the V3 and V4 posts that they were not the best, be they Deal Extreme or the better Esky ones. Yet other users have used them no problem, either brand.

After triming and leveling my V3 handled better than ever. I did not wait to order another set it is on the way.

It may have helped that I have worked with the calibtation and repairing of measuring equipment, such as micrometers, vernier calipers and all types of precision equipment, for years before I retired.

The balls seem a little tighter but does not affect the handling, like I said it flies better than the stock parts.

The flybar holder also has to be loosened up, I put the cap on and installed the screws. I then worked the flybar until it was free and sloppy.

The only time I did any filing was to remove a little plastic from the bottom stock blade grips.

All my parts have worked with the stock parts. The only problem was that the screws that go into the top holes of the outer shaft are too long, use the stock screws and locktite.

I have done extensive research in this forum regarding the Esky metal upgrades and have found a lot of the same problems were reported with those.

If I was to leave feedback at Deal Extreme it would have to be positive.

Am I lucky? I will find out when I get the next set and instal them.

i too have had a rather good experience with the DX parts. i still need to make some adjustments to the swash, but it is far more responsive than before. i even used the blade grips, while i can easily see how people would hate them, i was able to get them to work and they have a firm grip on the blades while still allowing them to slide back and forth smoothly.

there are two things to keep in mind with the DX parts... your part rolling the dice on their quality, and you need to be smarter than the parts when you install them.... this means taking your time, using grease and thread lock, and looking for problems and potential problems.

You adjust the upper blade tracking by adjusting the Control Link length.

I just turn it a half turn in one direction. If tracking gets worse, turn it a full turn back the other way. If it got better try another 1/2 turn and so on.

Had a similar problem too after replacing broken blades, and could't get the tracking right. I got rid of most of the vibration after switching to another set of blades. Maybe the first set was unbalanced and/or had uneven twist.

whoo. Just got back from flying my heli in my living room. I had a small blade strike (Some nicks in the bottom and upper blade one side each set) and now I have TBE. My shaft looks perfectly straight, my flybar, LOOKS straight. Anything else? I have once or twice gotten very low tbe, and I just recharged my battery and it was gona. Let's see if this happens again!

The stock motors are identical on both helis, as are several other parts.
