First Flight of a Restored Hamp

I'm guessing the Hamp doesn't have the original engine.

Yes, the Hamp had a 1700 cu in radial and I guess they used an R-1830. The cowl does look bigger.

None of the online videos I've seen bothered to mention the engine--really poor editing.

The Nakajima Sakae engine family was based on the R1830's predecessor, hence aside from modified cowling to account for the somewhat wider R1830 (due to larger cylinder dimensions, namely stroke and maybe bore), the Sakae engine is very similar to the R1830--I've even heard that they have similar mounting points on the engine block/crankcase.

Great video - thank you M MIflyer

I do not know what the duty cycle is on that starter but I am sure it was well and truly exceeded. If it is the normal E180 used on R-1830's it would be a 30 second limit.

Given the R-1830 is normally very easy to start I wonder why this happened.

I am not seeing the Zero start-up? It is already idling when the vid here cuts to it. Were you watching on a phone and see the digital slow prop illusion?
