Thanks for the response Tom. It was helpful.
| Quote: | that job clearly belongs to several others
|
But.. but.. Tom! I always felt you... oh, never mind.

I appreciate your opinion. But I wouldn't be able to judge this thing, I am
not a pilot but intend to begin lessons soon. My FS has a 503 DCDI which is
1/3 again the power of the 377. Heavier too of course. I have heard others
say that the 503 is too much power for the FS. I fell in love with the FS
when I saw one, with the 377, at Brian's Ranch (Mojave desert). It seemed to
fly just fine. I don't know anything about T.O. distance or rate of climb.

to add any more weight on top
|
All of our measurements so far indicate that the Generac, w/o reduction,
will weigh in at about the same as the 377 (which my notes indicate is 84.5
lbs with exhaust and reduction).
| Quote: | even more afraid of the vibrations that the Generac will create on the
entire airframe.
|
I have heard over and over how smooth the Generac is- even smoother than
many of the 2-strokes such as the 503 WITH isolation. One feller (on this
list?) said that bolted to the airframe with no vibration isolation it is no
worse than the 503 (IIRC).
| Quote: | and the plane weighed 325 LBS
|
I think mine is lighter- weighed the airframe and engine separately, mine
should come in real close to 280-285.
| Quote: | I guess what I'm saying is to consider a 377
|
What is your average fuel consumption?
| Quote: | it has done well for me over 500 hours.
|
Any overhauls? Major repairs? I have read horror stories about premature
demise of expensive Rotaxes.
| Quote: | I found that the 447 was OK, but did the same thing using more gas, and
felt overpowered, and could exceed my VNE of 90 in a blink.
|
What do you suppose my 503 will be like on there? I assume it will climb
like crazy.
| Quote: | If you were local, I would let you try it for yourself.
|
Thanks- but I would probably kill myself and all of the bystanders, not
being a pilot. Well, actually I have flown Cessnas and Bobcats.
In all of this, I am not asserting anything. I invite your comments please.
I know almost nothing about all of this and do not pretend otherwise.
Thanks
