Counterweight arm void.
Counterweight arm void.
Does anybody fill in the blank area oppsite the the fiberglass tip on the elevators and rudder counterweight arm? Or is this a no no. If you do fill it in what would work good to fill it in with? I realize that it woud have to be balanced after it is done. Thanks

Welcome (whoever you are ) Im a bit confused by your question. Do you mean the void between the tip and the rib or do you mean some other void? You leave the void between the tip and the outside rib but you cover the end hole with fiberglass or some such.

OH, ok, I understand now. Sometimes Im a bit slow.
I dont know of anyone that has done that but I cant see a reason why you couldnt. As a matter of fact I like that idea and might just ponder on it a bit for PJ. The only thing I can think of that you would want to consider is access to the counterweight. Im sure that it would make the tail look that much more finished.
Does anyone else know of this being done or why it shouldnt?

Yes it has been done. Some guys glass and fill in the entire tips to the point you no longer see rivet lines. Looks real clean that way but creates more work. Makes it look composite. But the purists say a riveted airplane should show rivet lines. I agree with Mustang. Give it somewhere to let moisture out. It really is your own decision.

If you mean the tips on the elevators, Yes... I plan on doing so, as that is the leading edge which is open. I plan on using West System's fiberglass chemicals.
On the HS tips, I plan on leaving them open. They face aft and won't affect it aerodynamically.

You should blank off the fiberglass cavities in the tips of the stabs and the vertical as well. It tells you a couple of options in the instruction pack from Van's. Do it one way or the other.
When you originally asked the question, I thought you meant the inner rib cavities behind the counterweights. They should be left open as stated.
Also, a number of builders have used excessive bondo and glass smoothing out the step formed by the counterweight skin, E713, I think it is. Avoid this also. Some older RV's have been found to have corrosion under the glass/bondo in this area. Sooner or later the aluminum and glass delaminate and the water wicks in by capilliary action, and causes corrosion.

Dear Guest,
Good Question! It would seem that everyone does, and this is because there is not much material in the tip fiberglass to catch the pop rivet. I sliced up some .016 alum that I will laminate onto the inside of the area to be riveted. I will then drill the holes out and dimple or countersink as required for a nice flush rivet.
I was talking to my experienced RV guru the other day and this is what he does. (He is building his eighth RV)
