- Over a decade of building by Bob Barrett and his 1933 Great Lakes biplane is getting close to being ready to fly. It's time to see if the Warner Super Scarab 7 cylinder radial engine will run, something it has not done in 54 years!

Those sure are short wings......ha ha...You all have a wonderful new year.
Yes the stall speed is very high at the moment! You have a wonderful new year as well.
The engine was overhauled 54 years ago and placed in storage. I am not sure all the details on the work.
Awesome!
It really is. I am very excited to see her fly.
Did the guy in Traer Iowa overhaul that Warner engine? He would know all about them.
Is this Warner with the better crankshaft that doesn't have to be inspected every 200 hours?
I am not sure. What is the inspection requirements or is there an AD for the crankshaft?
Many years ago, I knew someone who had a Fairchild 24 powered by a Warner. An AD was issued for the crankshaft. The prop had to be removed and the shaft had to be magnafluxed for cracks every 200 hours. Some warners had a better design that didn't need this inspection.
Okay well I will try to find the AD number and see if that applies.
No one should crank an engine over that long without a pause to rest the starter....
It did seem like it was getting cranked alot. It would be interesting to know what the duty cycle time is on the starter. Remember that this is a very low compression engine, it only needs 73 octane gas, and its a massive starter motor. I believe the weight is almost 20lbs.
