It is a Sandisk 8GB, so I bet the dropped frames are just the crappy old Generic 808 camera. It used to not drop frames, just didn't have a great quality smooth picture. I think it's the battery. This new #16 camera should fix all my problems!

I fell for the 720p nomenclature, but you can tell this is no real 720p. This Vid was before the battery started going out.

Can't wait for the #16.

Is this still the best source for this camera?

You can't go wrong with Sandisk. IMO they are the most compatible, but also the most expensive.

I forgot to mention in my previous post that I also have Sandisk no-class cards (i.e. very old cards) that also have no dropped frames with the #16 or #11. However, used in my #3, almost 50% of the frames are dropped - well it looks that way, I didn't actually count the dropped frames, but there were many.

Hello again!

I've tested with success two microSD cards:

SanDisk 8GB class4
SanDisk 16GB class4

The Samsung 16GB class6 still won't work with the 0.18 firmware.

And I have a little problem. The right side of the image is blurry. Is there a way to fix it? I don't think that is a focus issue.

after I came home yesterday I left the camera recording and it recorded perfect 5:00 videos until the battery ran out...
What is the card brand and speed class you are using? The test write speed shows it does not meet the minimum recommended Class 4 (4MB/sec.) sequential write speed which might cause some issues. Run the CrystalDiskMark speed test on the card and post your results, especially the sequential write speed and random 512k write speed. I'd look for a new name brand microSDHC flash card that meets at least a Class 4 (4MB/sec.) sequential write speed.

The battery is dying and it is basically unusable due to having to resolder a new battery and the buzzing noise from low voltage.

I just bought a #16 off ebay last night per Toms recommendation. I researched many pages and narrowed it down to the 1080P camera and this one. the 1080P still has too many bugs at the moment, is heavier than this one, and the files are huge on 1080P. I usually use it on my ball cap as a flight recorder for my helicopter flying, but do have velcro on a couple of planes for aerial photography and "Gun Camera" photage of my buddy's flying.

Anyway, my question is, how well will my class 2 card work with this camera? Will it drop frames like my current generic 808?
I would think so! Since you've been reading about the HD cameras you'll recall a Class 4 card is the minimum recommended for the HD cameras.

FWIW, that 1024x768 camera you mentioned is most liked a 640x480 resolution CMOS sensor digitally zoomed to 60% larger image, which causes the image to be blurred and degraded.

Samsung 16GB Class 6 are known not to work and are on the "blacklist".

What is strange is that I have a Samsung Class 10 which works, but has formatting issues.

As you have noticed, there are no issues with Class 4 cards. There is a great risk of problems if you use any cards with a Class rating more than 4. So keep to class 4 and you should be safe.

Yep Tom that's what I figured. I will take some vids with the Sandisk Class 2 and then when I get my class 4, I'll post my results regarding dropped frames and overall quality differences. Tom did you see that vid taken with the old camera? Do you think it's the old blown up to 1024X768 and call it 720P trick? That would explain the sub par quality for sure.

Rimshot...that's where I ordered mine from last night. They have a good reputation.

The sources listed in post #2 are equally good.

yes, the camera is a blown up version, and should be given the same fate!

You might get some video recorded with the #16 and your old card that does not drop frames, but as the level of detail and motion in a scene gets more complex, the momentary data rate can balloon up from around 7Mbps to almost 25Mbps. This is when problems are most likely to occur.

Good stuff. I'll look for those things. Helis move so quickly that blurring has been my constant battle. I may go ahead and just order a faster card today so that it will be here when I get started. Thanks Tom!

A sample image would help. Has the image always been like this? Are you using one of the add-on external lenses? If it's not perfectly aligned with the internal lens axis it will cause this. The lens could be cross-threaded throwing it out of axial alignment. This is usually visibly detected by examining the lens module, and can be corrected by removing and correctly threading in the lens. Other causes might be some foreign material on the front/rear lens surfaces or on the CMOS sensor, and these could be cleaned (very carefully so as not to scratch the surfaces). Or it could be foreign material INSIDE the lens or a CMOS sensor which is not firmly seated perpendicluar to the lens axis. These are not fixable and you'd need to get a replacement CMOS/lens module.

With a heli, you'll also be more prone to getting vibration blurring and "jello" effects if you rotor is not really well balanced. This will be more visible as the resolution of the primary image improves.
