Re: Wright Stuff C

Chuck,

Good idea to post in the FAQ regarding the bonuses.

Another possible indicator of how these work is to download the official scoring spreadsheet and enter sample data.

Re: Wright Stuff C

Update on my progress: After two weeks of "playing around" with my bi-planes, I've decided to give up. ( :lol: ) at least for now. I just can't get the biplane to work consistently and no matter what I do there appears to be stall problems. Anyways. That being said, my team and I went back to the m...

Re: Wright Stuff C

Eric, Wing offset varies quite a bit between typical designs in the AMA and FAI classes. Whatever is necessary to control roll. Also, it is not always desirable to control roll. A little roll in the initial part of the climb is sometimes deliberately trimmed in order to moderate climb rate. This is ...

Re: Wright Stuff C

Does anyone else have trouble with plane inconsistencies during competition? I test my plane out a couple of nights before, and I am pleased with my results. When I bring it in to compete, it does much less than desirable. I try to keep my plane at a stable temperature, and I am almost certain that...

Re: Wright Stuff C

Luke is solo. It's probably too late for this year but hopefully if he does well, more kids will take notice and want to try WS next year. Luke is a senior but I have an 8th grader too, so we'll stay with it and see how it plays out. I agree a biplane with lower wing loading is better for this part...

Re: Wright Stuff C

Franklin,

Biplane should give you about 10% additional flight time.

Re: Wright Stuff C

Eric, When scores are communicated amongst the students at an Invitational keep in mind that sometimes students are talking about a final score and sometimes they are talking about flight times. Probably you and your son have already encountered this. A total score will usually include the 5% bonus ...

Re: Wright Stuff C

Eric,

With the good results your son is getting, hopefully he can start to fix his school’s negative view of build events. Good luck with the “working with students” part of SO. I’m thinking you’re better in this than you let on.

Re: Wright Stuff C

that sounds like a bit of a threat... It wasn't directed at you, but yes. I've gotten a lot of help here (thank you!), and I've respected requests not to share certain things. I feel like I should put on my flame suit because I know not to expect much support in my argument (understandably): I can ...

Re: Elastic Launched Glider B

I see that Coach Chuck already answered. Ditto. Thinned duco to reduce weight. And, it’s plenty strong enough. My team uses CA in small amounts for certain joints, including: wing dihedral, wing to pylon and front hook to fuselage and thinned duco for fin to stabilizer and stabilizer to fuselage and...
