What have folks used for ballast to do max gross weight and other c.g. testing during their Phase I period?

We keep a bunch of 50# bags of water softener salt in the shop.Â  We use it for ballast and for weighting down wing skins, etc.Â  Plus I have a water softener at home...



Salt is pretty cheap, about $5/bag.Â  The plastic bags are more durable than the paper sacks.

I bought 75# of lead shot at Cabellas and put it in a plastic bag to keep the lead dust away from inside the plane, but I found that I only needed 50# - I keep it in a plastic bucket shock corded to the rear of the baggage area. That way it is easy to remove when I need to load baggage

I'm not at that point yet, but my plan is to use 5 gal water jugs (at) 40/lbs a piece when full.  About as cheap as it gets and I can quickly configure different weights.

When you use something as ballast, you should assume you'll spill it.  In

that context, water or dirt or sand=good.  salt=not so much

Whatever you choose, you will need a lot….  

   

I used 80# sand bags.  I placed them in garbage bags to prevent spills.  When I was done….the sand went into my kids sand box.

40# water softener salt bags work great, especially if you have a use for them afterward.

Put the lead shot in a PVC Pipe segment sized for the desired weight and glue on caps.  Easy to manage and doesn't spill.

I bought 150 lbs of shot from a local sporting goods store and used that.  It's easily moved around and can be secured.

I think might have answered the wrong question.  I thought he was looking for what he used for Max GW testing.  Need a lot more than 150lbs for that.    

   

So my new answer is……I pack a survival kit with water in it.  Weights about 20 lbs and is all the ballast I need to day to day flying…..

why do all this testing at all? If one builds to  the plans and uses the hardware provided, why so much testing? A unique design  "homebuilt" would require complete testing. An RV kit built to Vans plans and  rigged to Vans plans should perform very closely with the numbers as provided by  the kit manufacturer. At least as closely as Cessna did with their marketing  driven operating handbooks in times past..

Hmmm. Color me ignorant but I thought due diligence dictated that you are supposed to test the aircraft in a variety of weight/CG configurations in actual flight to verify performance.  The only way to effectively do that in phase one is with ballast.  Regardless of any one else's opinion, I still plan to explore multiple configs because I want to know what the no kidding flight characteristics are before I plop pax and bags in the plane.

I do it because I want to understand how my plane flies at all ends of the spectrum.  Knowledge is king......

By definition, we test to verify everything was built to spec.Â  I.e. you canâ€™t know you built it to spec unless you test.  

Â   

Besides, do you really want to find out how it behaves at gross with your family as the ballast?

Rene,



You are correct, 150 lbs won't take it to full gross weight, but having it back in the baggage area will move the cg considerably aft.  Fly it for a while and get used to the different handling.  Takeoffs and landings are different with aft CG in the -10.  Take the time to learn to fly it with the aft CG.  The flair for landing and takeoffs with aft CG are different.  I have learned to fly the airplane differently based on where the CG is.  Use the 40 hours to evaluate your flying skills.  Its fun and there is no pressure from passengers or other pilots.  You can do touch and goes all day long without ever touching the nose wheel to the ground with aft CG.  With forward CG, the nose wheel is coming down.  Not abruptly but very soon after the mains are down.  The -10 is a wonderful aircraft and I have really enjoyed flying it.
