Paul Venne has requested advice regarding potential approaches to the removal of mottling on the crankcases of an old OS Max-S 30 RC and an OS Max-H 40 RC. We all encounter otherwise nice engines with mottled cases, so this is of general interest. Any suggestions??
Greetings! Noting that a lot of folks quite rightly don’t know where to look on this site to add a comment on a topic for which there’s no established thread, I’ve set up this new thread which is intended as a place to post any and all comments on any subject for which no specific thread currently exists. I will monitor this thread regularly, and if a topic comes up that appears to warrant its own thread, I’ll create a new separate posting for that topic.
Hope to hear from some more of you!!
At the request of my friend and colleague Gordon Cornell, I’m trying to learn more about the life and work of George Fletcher, best remembered as the chief engine designer for International Model Aircraft (IMA – FROG) and (briefly) E.D. All that I know so far is that he worked for Davies-Charlton (D-C) Ltd. in the late 1940’s and then worked briefly for Alan Allbon during 1950 prior to Allbon’s near-collapse as a result of the infamous Purchase Tax ruling. In around 1952 George replaced Bert Judge as IMA’s chief engine designer, remaining there until 1962, when he mover briefly to E.D. Along the way he remained active as a hands-on aeromodeller, winning the Knokke no. 2 Trophy (C/L Scale) in 1960 with his fine SE5A.
Gordon has a recollection that after the “original” E.D. company folded in 1963, George may then have gone to work for Dr. Joseph Ehrlich of EMC motorcycles fame. Can any reader add anything to our knowledge of George and his activities?!?
