I'm getting ready to look into sealing the gap between the

elevator and stab. on my model 7 and was wandering what affect it had on the

flying characteristics.



Does it make it more pitch sensitive or just give you more pitch authority?

I read in the archives that sealing the gap gives you more pitch authority

but does it also make it more pitch sensitive? And what about speed does it

help out any there too...Opinions and comments please.

Most of the 5s and up seem to have a forward CofG configuration due to heavy 

engines, it helps getting the a/c to stall.

Hi Roger, I'll echo Michels sentiments here also. I couldn't believe the 

difference after filling the control surface gaps on my model 1. I think the 

greatest benefit for me was the confidence it gave me in landing because I 

new the responce from both elevators and the rudder would be there when 

needed the most. Before my 1V is complete I will definetly be filling gaps 

because in comparison to the model 1, they are much larger between elevator 

and rudder and I feel a lot of authority can be gained by applying a simple 

fix.



Regards

 Hello Roger,

 Before I gap sealed my model 3, I couldn't do a 3-points landing, the 

 plane would stall and touch the ground with the main gear first, even when 

 I was with the stick in my stomach. Now, it's just perfect.

 I don't notice any more sensibility in the pitch, only that little extra 

 authority when the stick is entirely pulled and the plane is near stall 

 speed.



 Cheers,

 Michel

You probably won't notice an iota of difference in cruise, but with mine

there was a definite increase in the flare performance.

My experience has been positive, as well. Although, I didn't notice a huge

change, it did give me some more authority at low speeds.



Sealing gaps in control surfaces does not change flutter characteristics.

Some testing years ago (working from a faded memory here), showed that gaps

contribute to something like 30% control effectiveness loss. Nature abhors a

vacuum, and seeks low pressure. So the leak from one side to the other

affects the ability of the control to do its job.



I did not notice any sensitivity increase on my 2. I used thick laminating

film from the office supply store, and applied it like the pics on

Sportflight.com. Very easy to do, took all of 30 minutes to apply, and is

virtually invisible.



If you do run into sensitivity issues, you can correct that with CG changes.

Moving the CG forward "softens" the elevator, and aft makes it more

sensitive and gives more authority. Too far forward, and you might not be

able to raise the nose at low speeds. Too far aft, and it will get so

sensitive as to be uncontrollable.

Michel,

I meant to ask you a while back on this subject: how is your CG? Mine

is(was) a bit nose heavy, and I think that is why I couldn't 3 point with

flaps. The gap seals have helped, but to get the tail wheel down, it's still

tough.



I'm in the midst of an engine change, so my CG is somewhere near the

elevator at the moment. But I am going to try to get it further aft when

done.

I gap sealed my rudder, for the same reasons that you stated. Seems to be

ok. At least, I haven't noticed any adverse effects.



I didn't mention the effects of CG on the Yaw axis. I assume it could make

the tail squirrelly with aft CG. Good point.
