Test run Seidel ST770 radial engine, 70 cc 7-cilinder. Run-in almost completed. Runs on 6% oil / 94% methanol. Turns a Menz S 24x8 with 5800 rpm (without the ring silencer it runs 6000 rpm).
Next week engine mount on Gee Bee Senior Sportster (97" / 247 cm)
@freedomintheskies ; the exhaust is an original from Seidel and costs about 100 euro. The only problem; I had to wait nearly one year for it! The company Seidel is a disgrace for German workmanship and service....

Could you provide information about the price of your exhaust and where to buy it?
