Subject: Re: Zenith701801-List: Bunny hop
Well I guess I have an opinion? An ultralight guy in our club likes
to crow hop something he has never flown or has never flown. Its pretty
difficult for him to have a type experienced pilot with him in a single
place and he won't find someone to fly it first. He builds confidence in
himself and in the plane.
My opinion is that if you don't have confidence in the plane, the
rigging or how it was built, it shouldn't be flown. If you don't have
confidence in your abilities you shouldn't fly. To me the stakes are too
high, it's either right and you know it's right or you don't and its
not. Either you have or had experience in type or you don't.
Being a new pilot with a new plane I will endeavor to get experience
in a 701 (not mine) and be certain everything is as it is supposed to be
before anyone flies it. I don't think crow, bunny, porpoising or sock
hopping is training or testing.. But hey, I am somewhat new and don't
know anything anyway.

701 plans, corvair etc, getting ready for my x-country and check ride,
did one go around yesterday, nasty, gusty cross wind, and rain, didn't
want to botch up a $130k airplane, throttle and altitude were my
friends.

>Does adding power like in a Cessna 172 (porpoise) help
Sure does Randall, as you obviously already know... the power is a
flight control just like the other three, and will avoid the high sink
crunch as previously described, or if not applied before it happens,
will avoid the nosewheel crunch that follows. It's called flying the
thing...or, if not applied... just being along for the ride!!!
Good weekend to all

Thanks for all that shared an opinion or experience with me on bunny or crow hopping.
I have put almost 5 hours on the plane, playing on the runway progressing
from high speed taxi to two wheel hi speed taxi and an occasional slightly
airborne scenario.
Although I have not had enough altitude to hurt anything, I can see where this
is going to end if I keep going. The way I see it, the hops don't allow enough
time to get in and out of ground effect and leaves the pilot over correcting
to try and stay on top of the plane. I now believe the best solution is to just
take off and fly it, settle down and get used to its sensitivity then land with
a power on.
Now that I have worked out most of the little bugs, I will get my biennial in
order and go as flying as planned.

Naw Kevin, that's just Gus' famous carrier landing in the corvair powered 701.
Seriously though, while Gus recovered excellently from this hard landing, you can
see how things could get scarey in a hurry if you wern't ready to recover from
such an event.

Wishing you well, the key for me was to concentrate on stabilizing the airplane
early during the down wind, trim, airspeed, altitude and knowing which way the
wind is blowing, when I am behind the plane I'll do a go around, tracking the
runway and start my turn back to the pattern at 500AGL or the end of the runway
whichever comes last. Landings are mandatory, but I choose, when all is right.
Humble musings of a beginner.

| Subject: | Bolts, Propeller - 6 ea. |
I am trying to find some propeller bolts for my new project. The prop is a Woodcomp
3-blade ground adjustable prop on a Rotax 912. The bolts that came from
the factory are 8x140mm. I don't think the bolts were sized right at the factory.
The shank or shoulder of the bolt is about 110mm and the prop, hub and
spacer take up 125-126 mm. That leaves the shank about 15 mm too short.
I talked to Lockwood and they sent me 6 bolts, with exactly the same shoulder.
I called a place that sold Woodcomp props and talked to a fellow there. I'm
having a little trouble getting follow through from him.
So, what is the opinion about putting the prop bolts back in and torqueing them
down. They were in the engine for 380 hours. Somehow I don't think that is
what I'm going to do.
Does anyone know a reliable source for some bolts?
Thanks,

Mike, this is exactly what a Bombardier pilot said in a recent Montreal EAA
chapter meeting, when somebody described his plans for testing (which
included hopping).
Good luck

Tommy,
This doesn't directly answer your question but may help. As I
understand it, there should be no shear load on the bolts as the
driving force is conveyed by large surface area under the pressure
achieved by maintaining proper torque on the bolts. As long as the
shoulder extends through or well into the parts it holds in alignment,
it may not need to be longer. Others with more experience or
credentials may explain it better or direct you to a good reference.
