Quick one p30
Designed and built by Ross Jahnke
The model is my own design called "Quick One". It's #11 in a series that started at the 1981 Nats in Seguin, TX. I built #1 in John Lorbiecki's RV after losing my HotBox on a test flight. It took second in the senior class. That model looked a fair bit like a Square Eagle but with a sexier fuselage and fin.
#11 shares nothing with #1 except the name. #4 and #5 were published in Model Aviation May, 1989. They had a pop-forward wing DT, which I started using on #3 around 1985. It was probably the first such DT published. The design kept evolving over the years, until #10 and #11 were built. The last two were significantly smaller, in wing area, following John O'Dwyer's paper in the 2001 Sympo. #10 had a pop forward wing, VIT and a Tomy timer. It was lost due to a timer malfunction.
#11 has a two function electronic timer from Micro Flier Radio with two micro servos, which is lighter than the Tomy Timer by a gram! It also has the 1/2 wing DT (maybe also a first). This is by far the best DT for P30 in my opinion. It comes down in spite of thermals, as you can see in the video, but not fast enough to do damage even on hard surfaces like the gravel roads on our sod farm.
The wing has a carbon capped spar, trailing edge and carbon capped ribs. The airfoil is the dihedral break and tip airfoils for Alex Andriukov's mid 1990's F1B. The Stab has a full depth 1/16" spar with carbon caps but otherwise normal construction. Fuselage is 1/32" tube with silk inside and out. Tail boom is scrap from F1B. I molded the joiner from carbon myself. the front end used a clutch like the Rick Pagnell design on your website. I am currently using one of those orange props but the front end allows me to change them easily. I usually use the silver or blue props on my models as you can see in the photo. It's under-weight without the tracker and overweight with it. Covering is silver 1/4 mil mylar. It's surprisingly visible especially when it spins down.
