Very nice article. Your team is living proof of how far hard work and good analytical skills can take you.

Re: Wright Stuff C

Eric, I saw in your comments connected to your flaring propeller video that your initial plan was to set the overall pitch to 5” and the prop blade tip pitch angle to 30 degrees. Your comment then mentions as you noticed that this 5” pitch would create a blade root pitch of 60 degrees. After conside...

Re: Elastic Launched Glider B

Brian, Thank you so much for the advice! I tried the shin today and it worked great! I got about 24 seconds in my gym so that was a improvement of 7 seconds. Much appreciated. Max Max, Glad the shim to add wing incidence helped. After adding the 1/100”, you might have needed to add a tiny amount of...

Re: Wright Stuff C

Xiangyu,

Excellent results under very poor conditions. I heard throughout the day from my teams about the blowers being on and a serious problem.

Glad you were able to meet some of my students.

Re: Elastic Launched Glider B

Brian, On both of my flaps, the trailing, middle edges of the foam are about an inch lower than the trailing middle edges of the balsa wings, I don’t really know how to explain the deflection of my rudder, but I’ll try. The very bottom of the balsa leading edge is 4 mm from the carbon, and the bott...

Re: Elastic Launched Glider B

I have been having trouble with my transition. The glide is extraordinary, but the transition at the top isn't great. The plane looks like it will transition well, but then it dips down and loses about five feet before it finally snaps into its good glide. Any tips? Max, What glider design are you ...
