Yes - they are interesting engines !!!But there are also reasons why we don't really see them :Air cooling => reliabillity problems (Arial)The Suzuki was a very succesful racer for years, but somebody found out that 'folding' it out to a V-configuration, allowed them to move the carburators from the sides (making it much narrover -> better aero dynamics), better breating -> more power and better lubrication of the crank and conrod bearings.That said - I'm looking forward to see your unique take on this type
The Danes had a motorcycle with an interesting engine - the Nimbus. An owner told me that the rear cylinder regulated its top speed by gradually tightening up.
Are those plastic gears?If so, are they just for mock up?Sid
I always like the square four. Not without it's problems for sure, but an fun and interesting design. I will be interested to see your engine progress.

I will be interested to see your engine progress.As with V-Twin engines in motorcycling, the lead cylinder shields the cooling air. No longer an issue with many contemporary liquid cooled models . Back in the early days, packaging a liquid cooled solution too expensive and too bulky for vehicle size. The Air cooled V-twins out lived the Ariel, most likely by cost times number of cylinders and the strength of the company's market.
