Reflexor


Jay Scheevel
 

Hi Mike,

In my opinion you are overthinking this. Those who know me are laughing now because I am famous for over thinking things when I was building. Fact is that you won’t know what the “right” settings are until you fly it. Then you can put markings on it and use those as your guide. Just build it and move ahead. My two cents.

Cheers,
Jay

Hi Chris,
I think I understand what you are saying; more weight requires more lift.
And the reflexor can be used to trim with the ailerons rather than the elevators.

I was considering neutral to be both ailerons with 0° deflection from what the plans call for. At that setting should not any trimming be able to be done with the elevator ( with correct C of G)?

The reason I am thinking of a detent is that I've been reading how powerful the reflexor is and am considering that if it was inadvertently left in the wrong position at take off it could quickly be set in a neutral spot without over correcting.

For that matter, even when setting it for take off, I could know by feel where a starting point is.

Your thoughts?

Thanks, 
Mike 

BTW , I picked up a small engine throttle handle at Princess Auto yesterday👍...can't wait to install it

FYI, I took off once with full up reflexer.  I had to hold about 20 lbs of forward stick to keep from pitching up too much.  Controllable but not fun.
As preflight I used to set the reflexer at 0 and then I'd confirm the ailerons were neutral.  I don't see that a detent is important.

Well the verdict is in
I'm not going to bother with the detent.

The less I have to build,  and as Jay says, think about, the sooner I move on to the next phase.

Thanks for all your input it's been informative and reassuring!

Now....back out to plowing the hiway yet again......

Mike-----------  The other Mike and Jay are exactly right. Don't overthink it.  If built per plans, even if you don't do your checklist and the reflexor is set wrong, most airplanes will fly although you may need some extra pressure. You will feel this on the takeoff roll and you are  able to set reflexor accordingly. You will notice in the video I have posted about my first flight, after a bit of a long takeoff roll, I grab the reflexor and crank some up aileron to get a good angle of attack. It would of flown with more speed, but I had a bunch of elevator and still wasn't getting a good angle of attack.  No big deal and I was aware this may happen.

 Now I am prepared.  I still haven't flow at 1250, but as in my Dragonfly this is what I intend to do.

 With the higher weight and the CG in the back I set the reflexor so the ailerons are down a bit. This kind off acts like small flaps and allows the wing to lift a bit more. Once in the air, I use the reflexor to trim it out so waterline is level or best speed is achieved. On landing I will set ailerons up a touch to get a bit of a flat approach to the runway and this allows the tail to settle quicker.

 This is how I find it works and others may vary.

 The Q and the Dragonfly were originally built without a reflexor and there are some flying around as per original plans.

 The reflexor helps to make them better airplanes.  It's like having a cordless drill, you don't need one, but it's nice to have.--    Chris

I've been looking at installing a lever to activate the reflexor, but in the interest of optimizing space  I'm thinking of using a linear slide.
I had this piece kicking around from some car modification that caught my eye and set me to thinking.
I just stuck a bolt in a preexisting  hole to simulate a handle. The piece of course would have to be cut to size etc.
Attach a cable on the other end and voila,  a push pull slider.
The handle ( bolt here) could  even be given a light twist to  create friction against the other half of the slider 

QUESTION 

Does it require a lot of force to activate  the reflexor, hence the lever or because of the offset arm on the reflexor it wont be a problem.

Thoughts?

If I can do this I can mount directly under the surface of the console 

Cheers
Mike

Mike----------------  Not much force needed to move the reflexor.  If yours is built already, grab the cable with some vise grips and get it to move.  I am just guessing here, but I think on mine 5 lbs pressure would move it.---------------  Chris
