Thanks for this Denny. I didn’t know that Rudy ran a Starduster event at the Nats. I am building this one as a back-up for my Classic C ship – I was told by Brad Bane that the SD900 ‘grooved’ well and was capable of flying stably in stronger winds than I would like to fly my Nelson 36 pylon model in. Does Rudy’s event require that it be an actual ‘built-to-the-plan’ Starduster, or are modifications allowed?
RoyFor what’s it’s worth (probably nothing!) I finally had a minute to measure both my SD900 stabs. I built them decades ago from kits. Both are powered with KB 7.4’s. The one measures .735 at the front spar and the other .687. I can’t tell you which flew better because I didn’t even know there was a difference. I’m not much help, but just wanted to give out some data.
Hey Roy, Simon, Drake
The event Denny was referring to was the Starduster Cup event flown each year st the RJK FF Follies at Muncie. The event is for any kitted Starduster version. The. Original 1/2A, the X,
the 350, 600 or 900. Any engine, including electric is ok. Changes to strengthen the model are ok, but not changes To basic planform. I’m not going around measuring models or stab thickness
for that matter. Roger Erridge won last year. This year’s Follies flyer is already posted on the contest calendar. Bring those Dusters and join in the fun.In fact, if you look back on under ‘contest information’ to the entry ‘2017 FF Follies’ there is a pic of the Starduster Cup.
I have a Duster 900 that is looking for a home. I built it several years ago, covered with Japanese Tissue. I saw Burse Augustus’s Duster 900 fly with the Nelson 36; it went like a scalded cat! Here is your opportunity to fly in Rudy’s Starduster event. I plan on bring it to Muncie for the first contest in June. The airplane does need a little work, you need to mount an engine. I had planned on a radial mount but there is a week between the first and second contest. I plan to be at Muncie on or about Wednesday, 2 May. You can pick the airplane up at my trailer in the AMA camping area by the shower house.
A Duster story, I took a brand new Stardust 600 to the 1983 Nat’s at Westover AFB. I had a Super Tiger 29 RR engine, on crankcase pressure, mounted on the nose. The darn thing would go straight out level, the engine would quit and the nose would pop up and stall. I try everything I could think of but it would not climb. I had never met Sal but I approached Sal and told him about my Duster problem. He never even blinked an eye and said, “It needs up thrust”. He said that his first 900 acted the same way until he added up thrust. He went on to say that any down thrust is the “Kiss of Death” to a hi thrust airplane. I believed him too
Hi everyone. Here’s a pic of the Starduster 900 I have now finished, having taken note of a lot of things learned here on the forum.
Thanks
RoyHi Scott, it has a K&B 40S on it right now, with a remote needle feeding the rear venturi. I also have a K&B 6.5 front rotor if the 40S doesn’t come up to scratch. I’m working on a new venturi for the 40S, with a slightly bigger throat and ‘TD’ style triple jets fed from an annulus around the body of the venturi, I don’t know whether that will add extra rpm or not, but I figure it can’t hurt.
