Re: Wright Stuff B

I do not claim to know for sure about your ES but most likely he or she will not take it apart to weigh. Mine had a clip that grab onto the plane and hang it down pulling on a scale. The whole plane stay intact the way you give it to him. I expect all ES to have a way to weigh it without changing an...

Re: Towers B/C

Just a quick and dirty approximate budget calculation. To get to a score of 3333 for Division C and no bonus point, you need a 4.5 grams tower. - Baking it before weighing, you can lose about 10% of the weight, so you need to build 5 grams tower. - For the 4 legs, let's use 1 gram 36" stick of 1/8 x...

Re: Towers B/C

I am not sure but my sense is that to be able to do 3200-3500 score range, you need a big campaign of finding the one in a hundred or maybe a thousand pieces of the 4 legs. You can setup a test and bin procedure to test a vast number of balsa sticks and acquire 4 exceptional few of the pieces that h...

Re: Wright Stuff B

How do you make a rubber with a weight in the precision of .001 gram? Maybe I am missing something or some special technique, but we are talking about a sliver of rubber at that weight. When I do mine, I make the first one by trial and error and estimating where to tie the knot to get closest and j...

Re: Flight Times

I've been getting around 1:40 pretty consistently, though its max height is around 15 feet so there's still room to climb. Planning on building/buying a torque meter, as well as getting more rubber so I don't have to worry about conserving :ugeek: It has been a long time but there is this trick tha...

Re: Wright Stuff B

What is the time difference? You have the perfect experimental setup for you to test right in front of you.

Re: Freedom Flight Kit plane won't fly

We worked on the CG to be 1/2 in to 3/8 in in front of the Rear Wing Post--this was based on the instructions provided. So, it's confusing for you to say the Wing Leading Edge.... So, we should increase the wing incidence & if we get to where it is stalling, to lower it? We'll try raising the angle...

Re: Freedom Flight Kit plane won't fly

The plane is gliding well, it is not stalling at all. Here are a few things I would do. - Make sure the balance point (center of gravity) is about 3/8 of an inch inside the wing leading edge. Do this with rubber motor attached. Reread the instruction on how to do this if you are not sure. - More imp...
