Hi Paul.
Do you think motorcycle drive chain can take  6000rpm?
What is your opinion simple to make chain drive PRSU?
I appreciate your help.

It might work. I think a late model Harley cog belt would work better.
Chain and belt drives take up more room in the cowl not leaving
enough for the cooling system. You also need an extra bearing
on the outside of the small e-shaft  pulley.

It was a Rotomax  charged cooled unfortunately.
Charge cooled rotaries are not going to fly for long on over about
70% power.

Also something failed in the rubber coupling, the gear box or the drive shaft
and the test Vampire aircraft crashed.  The rubber coupling shown had a
5000 RPM rev limit.


The company then went bankrupt.

I spent a lot of unpaid time trying to fix the many problems but I was pretty much ignored.

They had a well equipped factory but it turns out all the machine tools were borrowed
or leased. The debtors got little.

Thanks, Hmmm, interesting failure point on the CentraFlex. Why all the fancy machining
and balancing equip if the were buying RotoMax power ?

Thanks, Steve Carlisle

I am not sure I follow you.

Do you mean "if the[y] were buying RotoMax power?"

RotoMax was designing and building the engines them selves.
