I fly with 50 lbs ballast in my HR-II. This helps keep the tail wheel on the ground after 3-point landings. I tried with 232 lbs ballast, works even better.

So it's not just about the weight, but where you carry it as well. I have already moved my battery back behind the baggage compartment to help with the c of g, and I use the stock (heavy) Van's tailwheel. It might be better to clamp a zinc anode (for weight) on the stinger.

If you are trying to build an award winner, you will get dinged if the judges cannot see the rivets. Aluminum airplanes are supposed to have visible rivets and if a judge can't see them he assumes the builder is hiding something.

Experimental aluminum airplanes are supposed to look how ever the builder wants them to look. A judge should look at the quality and not let their own opinion into their judging. I know that is just a dream and the chance of having open minded judges is zero. But, that is just my opinion!

My co-builder/girlfriend was not impressed by the 'expert judges', she wanted to build a plane she liked. She has fillled every visible rivet with Superfil. For the complete airplane, we used 32 oz., and the majority is of course sanded off. I actually think we saved some weight, by not filling the rivet grooves with much heavier paint.

Default Light components

Don't forget the lightweight starter, battery, alternator and Magnesium Sky Dynamics flywheel, depending on current equipment this could save 20 lbs. In the last year this pilot lost 34 lbs, 10lbs of it after buying an RV-3A which is also going on a diet :-)

I'm at approx 60 hrs and 6 mos on the Ballistic lifepo4 battery. Saved me 6-7 lbs, with no reduced starting performance, and uses same alternator/system components as with the gel lead-acid used before.
