Where did you buy that good FC?
« on: June 16, 2017, 08:11:54 pm »
Here is a thread where you can post "I bought this FC (web link) and it...":
- works perfectly
- had these fixable issues (explain) (generally the baro issue should go here)
- avoid this one (explain) (generally more than simple soldering is required to fix it)

works perfectly should testing include all features (gyros, accels, mags, baro, RF, FlexiPort, MainPort, FlexiIO, RecvrPort, ESC connectors) or at least include a list of what was not tested.

FC's that have RF should come with cable/antenna of some sort.  Please remark if they do not.

Sparky2s don't come with a receiver cable.  For the receiver connector, I recommend soldering a servo cable to it (that plugs in your receiver) instead of the 3 pin servo connector that then requires a special male male servo extension.

Include shipping cost in price and make a note if the shipping was NOT international and may cost more.

If you see a post that is the same as what you would write, just do a "reply with quote" and add your name and +1 (or more for more FC's) outside the quote.  I will delete your post and modify the quoted post with your name and +1.

Use the FC names provided unless you see that I forgot one.  :)

I will try to maintain this first post as a summary of community findings.  Initially this will try to be a list of places where you can buy a good FC, but later I will try to add a list of places / board types to avoid.  I will mark posts when I add them to the summary.

There are no official places to buy any of these any more.  The closest thing is that Sasquatchlabs sells what is left of the final run of official OP Nanos (and some OpLinks).  Also, the official Sparky2 seller stopped selling them and an eBay seller seems to be selling the remains of that authentic lot.

Maybe we can start similar lists for GPSs, OpLinks (even ESCs, motors, Lipos, RC radios....) etc.

You remind me that I bought 2 Sparky2s from that guy on eBay.  The official seller of Sparky2 was HobbiesFly and they don't sell them any more.  I think these are what is left of those originals.

Just an opinion here.  Not so worried about clone chips on the boards as whether they work correctly.

Having said that, some OpLinks come with bad clone RFM22B's and some come with good clone RFM22B's.

FYI, same guy has Revo. He claims that his Revos are 100% from authentic components and schematics. Has horizontal MMCX connector, unsoldered pins. I didn't buy this, so I can not confirm that his claims are true. 36$ shipped (free shipping to Croatia).

I did have an issue with my oplink but it was a missing component. Bandgood replace it no cost.

I assume the issue was that the Revo RF didn't work.
