US Europaphiles, Anyone in need of Redux? Two other builders and I each need a kit. Anyone else want to get in on it. Saves about $35 on hazardous fees per kit. A case ships for the same price as a quart. Last purchase price was about $270 with shipping/hazardous (think of the children)...

Jeff- In a glass airplane you are much better off with a dipole.=C2- All a grou nd plane does is make it possible to use a quarter wave antenna instead of a half wave.=C2- For the Europa, there are several places you can put a v ertical dipole.=C2- Which radio are you asking about?=C2- To answer you r question directly, the ground plane is stand-alone, just like the other h alf of a dipole.=C2- If I were doing a ground plane in a Europa, I'd prob ably use several strands of copper wire or a thin aluminum plate under the vertical quarter wave.=C2-=C2-If you are near a library, check a copy o f the "ARRL Handbook 2010" for a full discussion of ground plane antennas. =C2- You could also Google "Ground Plane Antenna."=C2- I did and=C2-I found a calculator for an amateur ground plane.=C2- All you need to do i s plug the desired center frequency into the calculator, and it gives you t he radial and whip lengths.

Jeff Emphatically yes. Bob Knuckles book the Aeroelectric Connection has a good section on antennas. Different antennas require different ground planes, and his book does a good job. Well worth the money. Once you get into avionics, a lot of self study and and good crimping tools will make all the difference in your planes electrical performance.

Jim, Would you mind letting me (us) know what prop you'll be using, and your rationale for your decision?

Fred- I'm using a Sensenich ground adjustable.=C2- I have been working with Fli ght Crafters and it is their recommendation.=C2- They have installed seve ral with good results.=C2- It is really a pretty slick setup.=C2- The t wo blades are slaved, so you only need to adjust one, and there is a small gauge on the hub indicating the pitch.

Sounds good Jim...I've just spent the past few days emailing back & forth w/ Sensenich (Charley)...fortunately (for me) the Jab 3300 blade is also available as a "pusher" and can be set up as a CCW rotating tractor for my Sube...I figure it will be a nice "known" factor during initial flight testing...(not that I'm anywhere's near doing any).
