Mike B. Good news on the first flight, looks like just you and I are paying attention to this thread. I think the 4-Star and the Starduster are almost identical, and someday I will replace ours with a 4-star. We, (my son and I), had a Saito .72 in ours, no lead required for balance. It flew in a spirited manner, our field is at 5000 feet altitude. I am still kicking myself for dumb-assing ours into the ground.
Enjoy a great plane, I am sorry to see that the kit builders are one by one dropping out of sight because of the ARFs. I am currently flying an ARF, a Sportsmen Aviation from Hobby People, Ryan STA. It too flies great, but like all the ARF's that I have looked at, needed lots of tweaking to be airworthy. I am looking for a larger version of the Ryan STA, and I see that the discontinued SIG kits are going for around $200 on ebay. I guess kit builders are slowly fading away and the suppliers know this, but the old timers are willing to pay a premium fot a discontinued kit.
