Interesting. Oleg said he wouldn't go there himself because there wasn't enough data to make reliable FMs. But who's going to argue 90 years after the fact? IMO there's enough anecdotal evidence to make it near enough; e.g. the Camel is tourque-y and has a magneto switch instead of a throttle... good enough for the armchair pilot. Bring it on I say! Then progress to Spain and China... you beauty!
