What are the rules if I want to take and sell photos from an amateur built experimental airplane? I wouldn't be carrying anyone, just taking pictures or videos and selling them. Do I need a commercial? frank

What a bummer, Glad nobody got hurt, maybe a testament to the aircraft design. Ken Terrio's airplane was beautiful it was the 2003 Plans built grand champion. Hope Ken can get it all back together. Here is the NTSB preliminary.

I've got an ARU 44 gyro and I'd like to power it off my 24VDC system. It needs 115VAC 3 phase, and about 75W to 100W. Is there an off the shelf unit that can do this, or maybe someone knows of a schematic to build my own? I'm an electronics engineer so I can do this, but inverters are not my...

I have designed and built a headphone adapter/transformer for some custom-molded in-ear headphones that offer excellent noise isolation (passive). I actually use them as a musician. In the plane, they sound very nice and are quite comfortable. So - what I want is a boom mic. I've actually...

I have a Stitts SA-3A playboy I picked up recently. It has an A-75 Continental and a 67" Fottorp prop with a 47 pitch. The plans indicate this machine should fly around 120 mph with this engine; no mention of prop. A previous owner I spoke to said it cruised around 118mph for him. For me,...

I have on hand a triplexer with outputs for 2 VORs and one GS with one antenna input. I know that there will be signal attenuation with this setup, but what will be the real world effect? Will the VOR receiver be so desensitized that it will be next to useless? Will the ILS performance suffer...

I just bought a fiberglass homebuilt project with a conventional com antenna mounted inside the leading edge of the vertical stab but it doesn't have a ground plane yet. The instructions call for a 24in by 24in ground plane but there isn't that much room right there at the base of the tail. Any...

DONE!!!! Yep, I finally broke down and drug the table saw up the stairs. Made a v-block out of a chunk of 2x4 that I salvaged from a dumpster. Tried the v-block yesterday, and after 2 hours of setup time, finally got everything aligned and drilled the holes in the bike frame. Following that I...

Greetings, The subject pretty much says it all. I'm looking to hear from those who are flying a 3300 Jabiru engine. I've heard that there were some problems in the early days, but I was told that since about 2002, the engines have been working very well, with no problems. Can anyone confirm or...

Does anyone know much about these rocket powered planes that plan to race at Reno? Are they the same as Rutan's EZE rocket? And can they carry enough fuel to actually race around the pylons for several laps? Sounds like it will be a really LOUD race.
