Hi there Speedracer
I have been dreaming about bying the ASM Lancaster since I first read about it. My progress so far has been bying 4 .52 engines and a Seagull Dual Ace in which the first set of engines are being flown in. Why do the running in on a bench when there's plenty of air to do it in. I have done the synchronization mechanical. And that is just not good enough. It is not in synch in the full range. I have bought a twin synch, which I have not installed yet.
You mention a quad synch. What make is that? Where did You buy it and at what price?
Thank You and best regards
Mikael
