Hi Mike,

I put a camera and video transmitter on a Blade 120 heli around the beginning of the year. It works very well for FPV flying, but is a handful being a heli. My next project will be to put a camera with either head tracking or manual swivel capabilities on my e-flite Apprentice. Trying right now to figure out the best way to mount it for best visibility while protecting the camera.

Good idea on the meeting. I'd like to participate if possible schedulewise.

Hi Mike,  Thanks for the help, but I think I found my problem.  Damaged component on the adapter board.  Actually it is missing.  Could have come off from just handling.  It was L1 on the Interface Board.  You know what this part is?  I have removed the gps module and antenna from the interface board.  I am looking to just replace it as soon as I am able to determine where I can get a new interface.  I think from now on I will be setting up my own hardware instead of buying it already configured.  Seems I am disappointed more often than not with what I get with these plug and play devices.  DiyDrones store support was unable to identify the problem when I sent it to them.  Not complaining, but you should know more about what you sell.

yes it is the hi-tec HS-85bb it ha metal gears and a bearing on the output shaft i found that most servos blew out real fast on the tail of this thing and so far the HS-85bb has held up really well i got it from servo city for 20$

Hi Mike,

I've been getting help outfitting my E-Flite Apprentice for FPV here in a few weeks. Here's an Apprentice in Co. flying over Devil's Thumb. He's using a GoPro camera to record this wonderful qualtiy video. This guy also helped me choosing equipment to put onboard my plane. At this time this plane and mine mostly have in common that they fly over the same planet. But, I have aspirations

 http://vimeo.com/30959546

Everything's been ordered to equip my plane. I found another man, Chris Edwards who was flying FPV near Home Depot in Warrenton. He's a great resource in the area.  We're looking for available flying spaces out here west of Warrenton. It's beautiful open country just beyond where the TFRs are routine so there's not as much interference in flying activities. Lot's of pilots and interest in flying related things, however, in this area.

I'm not quite sure what you are saying. Do you thinbk I should have put my most recent offer of PID tuning somehwre else? If so, where?

Thanks Mike!  That was my first Blog ever.  Not sure if I can make changes to it...would check the speeling if I could as I was on the way out the door when I wrote it.  I am in AZ right now, but will be flying to Baltimore and staying there for a while.  How far is that from your area?  I know of a few good airclubs/fields south of Baltimore.
