e-Century Hummingbird - Swift > Swift poor swash and mainshafts.......What to do after you complain....

Hmmmm well in assistance to a freind that recently bought a Swift and had more than a few issues new out of the box.

It seems there are several reported cases out there. Sure Century will replace a few shafts, maybe throw around a few junk swashes back to their customers, but in the end if you want it to be a good quality helicopter you are going to have to make some changes. These are not normal tweaks that come with the hobby, these are replacing the original parts with others from other helis.....

First of all this one is no surprise was the main shaft being bent, before even installing it, it was bent. Not from a violent spoolup or spooldown, before even being put in the heli. Secondly which now has been reported even more and more is a very poor quality swashplate. The swashplate in many instances has also been the culprite of bad vibrations due to the huge slop and bad materials used. I am quite certain that Century would have been better off waiting another month or two..., having a few meetings more and mainly spending abit more on the kit and charging a tad more for a better swash and better machining on shafts. This would have prevented the wave of dissatisfied customers and their legit complaints. It amazes me even after all the time they took to release and test this heli that we the customers out there have to deal with their crap and show them how to do it.

Here are some pictures to demonstrate a couple of the issues as well as what was done to fix the problem..

This is the Swift swash and main shaft you get in your kit, some have been ok, but many of them have been crap. The white delrin material on this one "brand new" moves with the ball and snags and has more than a mm of play in the swash mold. Beside it a brand new bent mainshaft.



Oh what do you know, the Raven swash is not only much better in quality but also a near perfect fit on every way. Here is a pic to compare the two.


And here is the Raven swash mounted, notice the shiny silver mainshaft, it is a mainshaft from a Hirobo Evo. Now only twice to three times as strong but also available at several vendors and best of all it will be straight out of the bag!!!

You will note that in using the Evo shaft it will come down below the gear abit, which causes no issues at all, just looks different.





And if you do not have a Raven maybe you have a freind who has an Xcell around, and a spare sawsh. Here is a pic of the Xcell swash mnounted up, a pretty good fit as well and again, much better quality than the stock one.



I think Century was not ready for a 30 size electric imho, they only made a big version of a 3D pro is all they did, including issues.
I only hope for Centurys sake they can correct these issues very soon, make better quality shafts, better spindles, better swashplates get past these stupid mistakes.....

Well, said, do you have a part number for that mainshaft, I think I will get one on my next order.

Thanks

0412-110 is the part number for the Hirobo Evo mainshaft. Either Jet Hobbies for you in BC would be quickest Wedge. Otherwise Ricks RC or other...

I don't think this is just a 3D pro enlarged, I believe a litte more time and engineering went into the Swift, its good value for the money, and I think the quality is there, just a couple things that arn't perfect. Me, I can live with that, if I have to spend a few extra buck's so beit. I ran mine up today with no blades and it was totally free of vibrations, Im not going to use the stock crap woodies, I really don't like the fact that the woodies that come with it have a 4mm hole and the blade grip bolts have 3mm bolts. I will keep them as spare blades, hopefully to never use them I got some Rotortech 515's on the way.

Hey Will let me say this, I do know of and have heard of these out of the box with no issues on vibration. All I am saying is there are still however many that do have the issues. BTW for the money you can't beat the Heli Max 530mms'. Like 45 bucks and they are really good blades for your new bird.

After replacing the main shaft and swash , did that finally cure the shakes OICU812 ?

Im pretty much a newb to helis so this extra part swapping kinda is a bummer....but a learning experiance I guess.
Id much rather have a an enjoyable heli right out of the box.

My swift should arrive ina couple days....im scared I wonder if I made the right decision.

Hey, yes I do agree with ya, not saying there is no issues, there are already a few things I don't like about it and I haven't even flown it yet, I am just hoping that mine is one of the ones that has no vibrations. About the Helimax blades I m sure there may be some of them that are ok, but after the ones I had I will never buy any more of them ever.

Sparrow just make sure for a peice of mind to roll your main shaft on some glass before assuming its good. Make sure to relube all the bearings and so fourth in the head and go through everything as if it were a scratch built kit. Also I would suggest making sure your swash delrin is in tact to the inner of the swash not like the one I mentioned. Reloctitie anything that should be and ensure it is all good before first spoolup and you will be just fine.

And yes with a new main shaft and the swash my freind got his Swift smooth as glass, also we found some Evo landing gear "my stock pile" to put on it, so that will take care of the landing gear issue as well.

Wedge.... well there ya go, see I have cases of bad Swifts, and you have cases of bad HeliMax blades, lol. I bought a set of 600mm Heli-Max white gel cf baldes for like 50 bucks and they are spot on for tracking and performance, I was very surprised for the money.

Have a good weekend all.

Hello,
I'have the wooden blades and spool down vibrations.
The main shaft and the swashplate are OK.The wooden blades are well balance to.
When the main blades stop after spool down,I observe that the rotor blades are always in asymetrical position; more drag of one blade(always the same blade)?
Do you think that it will be the cause of the vibration?
Thanks and sorry for the bad english.

I think the blades could be a major contributing factor in this vibration, I m not going to be using them just cause they dont fit the blade grip bolts, the holes in the blades are much too big and there is too much slop in fit on the grip bolts for my liking.

you are supposed to use the spacers with the stock blades, they have 4mm bolt holes

Spacers??? where, mine never came with any, are you talking about the plastic ones you glue to the blade root, we are talking about the bolt holes being 4mm, my kit never came with any brass bushings, to make the holes 3mm.

blade spacers

Yes, mine did not have them either but all the new kits do as well as a new set of blades alone, you will notice also the manual tells you to use the 4mm bolts to attach the blades so they screwed up somewhere and made the blades 4mm and the grips 3mm thats why they started adding the brass spacers to the blades and the kits.

Hmm well, that sucks, I got no spacers, so the blades I got are pretty much usless unless I get some spacers.

could you try with just the main shaft and then with just the swash to see which one cured the problem. Also ive heard that putting some washers inbetween the head dampners also fixes the problem. Any ideas????
