Where are the gromits?

[reck]

Hi all,
And greetings from sunny Berkshire...

I';m new to the hobby, just got myself a quad based on a X525 frame from Badlands RC. Although it was fully assembled, the receiver was wired entirely wrong to the FC  and the ESCs weren';t all programmed the same  - and as Lee was unresponsive to my questions on battery connectors I ended up with the wrong type and had to solder new connectors on all of those. Lesson 1 then, if you buy from a UK modeller then don';t expect any better service than if stuff comes from China. But on the upside, your problems do arrive a lot quicker 

Now that I';ve fixed the basic build errors, I';ve balanced the props but the motors are not exactly lacking in vibration even after balancing them as well. I was able to knock about 25% off the measured amount of vibration, but thev cheap motors will invariably be a bit noisy. I would really like to use this quad for a bit of aerial video but I think that without isolating the motors from the frame it will be jello city. So, does anyone know where I can get my hands on gromits or urethane washers to isolate the problem:? I';m off to tour some model shops and Diy stores but if anyone has a reliable source somewhere on the planet that sells to the UK that would be excellent cheers!

Hi reck and welcome to the forum sorry to hear you had such a bad experience with a UK dealer, I will be interested to see how you get on with isolating the vibes on your motors please keep us informed on your progress

Good idea, you might try O rings, but make sure you get a reasonably hard one or you will just squash it and it will be doing nothing!

Would tap washers do the trick?

What shoddy service from your model shop, I guess they are aptly named!

You could try sugru, roll it into a sheet and cut whatever size and shape that you need.

B&Q stock sugru these days

silicon washers from Maplin might work nicely :

Maplin are not necessarily the cheapest option but I';ve got one 5 mins from my door :)

Well, Badlands are actually a mail order outfit. Make great videos, I';m sure he was having a bad day when he built my quad. My local model shops round here are actually excellent. The problem is that neither of them do multirotor (yet) as a speciality, so they tend not to carry the right bits and pieces.

In the end Maplin did have some grommets but I am not entirely convinced that they will work as they look too hard, so might get rid of the high frequency noise but not enough. I have some silicone hose from another project that might have the necessary compliance, just trying to work out how to fit it to the frame without destroying the basic structure.

I think the best thing is going to be to shell out another 20 quid for a new frame so that I have some spares when I trash this one.  To fit Maplin grommets I will need to enlarge some holes on the frame...  it may be some weeks before this gets fixed but I will report back..
