I have the opportunity to buy an 0320 Lycoming with  governor and prop. Anyone know of an 801 that is flying with this combination. I  am planning on an 0360 with a fixed pitch prop, but thought I'd see if there  were any information on this engine and prop combo that has actually been  installed and flown on an 801.

Dave,

Jim Frisby has a O320 in his 801, but I don't think he has the constant speed prop.  Search the archives for Frisby in case he misses this post.



I have a O360 in my 801.  It came with a governor and constant speed prop but I sold the prop and bought a wood one from Props Inc.  The wood prop is about 15 pounds in weight.  The constant speed was around 50 pounds.  Other builders suggested that the 801 is slightly nose-heavy to begin with, so I went with wood.  I was also having a hard time finding room for the governor.



I still have about a month of work to do on my 801 before it is ready to fly.

Jay,



Thanks for the reply. I'm about 99% sure that I'll go with the 0360 because 

of weight, among other things. I am building my plane without to many 

frills. I don't want to ad to the complexity of addtional systems and costs 

on things I probably won't use anyway. The engine prop combination is more a 

curiosity than anything else. I also found out the engine that I had 

referred to has been pickled for about 9 years. I think I will probably use 

an XP360. Haven't thought to much about a prop yet. What are you using?

I'm in the same boat, the 801 were building is about a month away and

has an 0-360 with a metal prop from Zenith's FWF kit. The constant speed

application only increases cruise by about 3 knts and is not worth the

5G's or more in cost. But one thing I can truly say is that this is one

huge plane to build. It is only about 15% bigger then the 701 but wow it

is incredible how much more of the hanger it fills.

Dave,

The prop that I have mounted on my 0360 is a 72x46 made from hard maple with fiberglass tips and leading edge protection.  Cost was $995 from Props Inc.

My initial gut feeling is you are underpropped by a large amount. If nothing else you need a larger diameter to send the prop blast across the tail feathers to make them work at lower airspeeds. 46" pitch will let you accelerate great on the take off roll but top speed will suffer. of course when I say top speed and Zenith 801 in the same sentence is pretty funny.  <G>Let us know how it works out... 

do not archive

Ben,

You are probably right about being underpropped for top speed.  But as you know if I was looking for top cruise speed, I wouldn't be building an 801.  My intention is for fast acceleration on take off and leisurely flying.  If this prop doesn't work out, I'll swap in another.  I'll post the results after I do the test phase.  



Thanks,

Jay Herron

I don't think that substituting construction foam board for the 

closed-cell insulation/soundproofing foam would be a very good idea 

because:



1. It is certainly not FAA  approved  and would be a real problem in 

the rare case of a fire. The closed-cell foam meets or exceeds certain 

FAR standards for fire retardancy.

2. Construction foam is very light and rigid. I think that the 

flexibility and relatively high density of the closed-cell foam is the 

main reason for its effectiveness.

3. The closed-cell foam is very easy to apply with random dabs of 

contact cement even on curved surfaces. You want to be able to remove 

it to gain access to fuel lines, electrical

     wires, etc.

4. Another big plus of the closed-cell foam is that it is very easily 

cut with a pair of scissors, and also,since it is flexible it can be 

pushed into crevices and areas which would be

     very difficult to access with a rigid and brittle foam board.
