Hi all,

I have been lurking in the background = trying to=20 learn what I can. I intend to use a rotary in the BD-4 I am = currently=20 building. It will be some time before I actually need an engine = but there=20 are some questions I have regarding the use of a 13b vs. a = 20b.

1: What is the difference = (average=20 installation) between the installed weight of the two?

2: What is the cost difference in = 13b NA, 13b=20 turbo, 20b NA?

3: Do Tracy's components work = with the 20b=20 (EC2 and RD-1C)?

The reason I ask these things at this = point is that=20 I am (as most) building on a budget. I also am at a stage that I = need to=20 make a decision about whether or not to extend the fuselage on my = plane. =20 The back seat in a BD-4 has practically no leg room. I am looking = at=20 extending the fuselage to get 5"-6" more inches leg room in the back = seat. =20 This would work if I can afford a 20b to counter the change in CG that = comes=20 with the fuselage extension. And there is also the fact that more = power is=20 always a good thing.

Thanks in advance for any help = given,

Bryan
