There is no way that I am going to go through that rigmarole 5ft above the ground at marginal flying speed. It is possible I believe to `jump` into the air in some aircraft by deploying the flaps and using the extra lift which that generates and then struggle on in ground effect as speed build up. Don`t fancy the idea much. When taking off the idea is to get the maximum lift for the speed you can attain. If you are slow you need a high lift airofoil. Deploying the flaps achieves that. As your speed increases you can fly more efficiently with a flatter airofoil section. Taking off the flaps does that. Cheers Pat ________________________________ Message 2 _____________________________________ Time: 03:48:07 AM PST US Subject: Re: Kolb-List: 68 From: "Thomas R. Riddle" Lots of variables. Standing in the wind, like Dana said, and using the Right hand or Left hand nomenclature should make it pretty clear, since that removes the tractor/pusher variable. One thing implied but not mentioned specifically, is that the belt reduction drive has the same prop rotation direction as the crank but the gearbox reduction drive reverses the prop rotation direction compared to the crankshaft. If BB had a gearbox reduction instead of his Raven belt drive we could swap props from his pusher Geo to my tractor 912, but not with the Raven.

It has a left turning prop. You have a GEO engine......with a gear drive. You will need a right turning prop. It might be best to not look at it as "the same prop as a Rotax". In var ious configurations an engine will turn a prop different ways (as Boyd poin ted out). What matters most is the universal accurate rotation description........if you stand at the back of the plane =2C and you watch the prop spin=2C does it spin clockwise? If it does=2C t hen it is a right turning prop. If it spins CCW=2C then you got a lefty.

FWIW, on T/O I set flaps first, before even starting the T/O roll; then open the throttle fully & keep one hand on the throttle and one on the stick untiI I get some altitude. That way your passenger (if you have one) can't change anything big, and you're in good position to handle an engine-out or bird collision or other emergency. I fly in ground effect, a couple feet off the ground, until I reach Vx or Vy, your choice. Then climb to my desired altitude; THEN retard throttle, raise flaps, whatever else I need to do. Keep both of your hands on the controls until then! I do NOT want to fiddle with flaps or anything else until the aircraft is stabilized in climb, at the target airspeed and a safe altitude. Certainly don't want to take a hand off when I'm only a few feet high. I realize if you're alone in a Kolb, and the throttle has a good friction-lock, you can take that hand off and do other things. But it's not a good idea to do any such things when you're still low. On a soft field you want to lift off the ground ASAP, then fly at a foot or two -- what Pat calls 'staggering into the air' -- until speed builds. That way, if you should fall out of a gust at least you'll only drop a very short distance. One very exciting thing happened on climbout in a friend's aircraft, when the flaps, set at 20 degrees, banged themselves down to zero, due to a worn notch. Neither of us were near the flap-handle. Glad to say my reflexes kicked in, I shoved the stick forward in about half a nanosecond, and we recovered uneventfully. It's good to consider, before even taxiing, "what should I do if this or that happened -- " Then you'll have a proper mindset ready to go when and if something pops up. Or down . Pat, I wonder if it would be easier for you to switch hands; drop the throttle, take the stick in your left hand & use your right hand for the flaps? At a safe altitude of course. Anyway, let's us all fly as safely as possible Russ K ________________________________ Message 10 ____________________________________ Time: 07:14:38 AM PST US From: "pj.ladd" Subject: Re: Kolb-List: Re: M3X pictures,numbers They did change the flap lever for the better on the Xtra, its above my head in the middle, and very easy and quick to get to and to operate.>> Lucky you! how they ever let my design out of the shop door is beyond me.

Mine is a _left_ hand pusher (standing at tail looking a prop, the top blade moves to the left - rotates CCW). Rotax isn't innocent on this either by the way. For reasons uknown, the 2-strokes spin their prop flange the other way than the 912... so the props aren't interchangeable pusher-to-pusher, tractor-to-tractor......

I guess it has to do with the aspect ratio, or some such. P.S. waiting on progress report from all the folks that are flying up to M.V. I Think I am going to leave Friday early to M.V. to check in and see the going's on there, and fly back Saturday, or late Friday night. Can anyone report on bug situation for those on overnight camping? I will take my tent and sleeping bag with me, in case I may want to experience my Army Infantry days all over again (no particular desire to do that btw).

That makes it lots easier just get the Rotax 912 prop, is all I got to remember. Ron @ KFHU ---- Mike Welch wrote: ============ Ron, Mike Sharp and I just had this conversation the other day.....namely; which prop do you need? I have GEO 1 liter with Raven Redrives belt drive. This requires a LEFT turning prop (counter clockwise rotation) If you have one of those SPG-2 gear drive units, then you'd need the same prop type as a Rotax 912....a right turning, clockwise rotation prop. But if you have the belt drive like I have, then you're looking for a left turning prop.
