Well, count one for "candle moth syndrome". I pulled out my first quickbuild wing yesterday, which was the right wing. I set it on the table, removed the bottom skin and went to work. In the process, as I got around to the leading edge, I noticed the two pre-drilled holes for the stall warning vane. So I flipped to the page in the manual and went to work cutting out an access hole and the slot for the vane. Only AFTER I had all that done did I remember I was working on the right wing. It was also then that I noticed that Van's pre-driled holes for the stall warning on BOTH wings. Oh and yes there is a caution note in the manual, but like I said, "Candle Moth"



In all my years of flying I was never given a reason why the stall warning is traditionaly on the left wing. So now do I accept an extra access hole, patch up the slot on the right wing and start all over again on the left wing, or is there any reason why the stall warning would not still work on the right wing even though it is not in the traditional location.

Paul,

   Of course the safe answer is to ask Vans about it. However since the

airplane stalls so wonderfully benign and level I can't help but think the

AOA is the same on both sides at the same point so shouldn't matter which

side the sensor is on.



My unscientific opinion,

Marcus

I'm not sure that it would make any difference at all, but if I were

in your shoes, I'd probably feel just like you do.  And, if I were

feeling that way, I'd probably proseal in a patch on the inside of

that slot, and then use filler to fill the slot back up and make it

smooth again.  Then I'd put the slot in the other intended wing.

No big deal.

I agree with Tim's suggestion on closing up the wrong wing,  however if I had it to do over again I WOULD NOT install the stall warning at  all.

Paul,

I wouldn't worry about it. The only reason that I know of for the stall warning being in the left wing is because of left hand patterns when landing. I'm not installing the Van's stall warning,  I'm going with AOA.

The reason I was told it's on the left side is  because the usual traffic pattern is to the left.  The left wing goes  slower in a left turn than a right so the airspeed on that wing in that critical  phase of flight would be the lowest.  This would warn of the stall on that  wing which would occur before the right wing resulting in the  stall/spin.

My Certified Grumman ...... has the stall warning switch on the right wing ..... as seen from the pilot seat.  However, you do have a valid point.  I'm not going to have a stall switch ..... or an AOA ....... I'm just going to use all the info the airplane naturally gives you.  If you ignore all those natural hints .... you'll probably ignore the stall warning horn too!
