What is the status on the Racing Beat three rotor Monster?

I was down there a couple of weeks ago and one engine had spit out
an apex seal spring and scratched up a housing. Jim felt it was
a quality control problem. The springs are special high temp
steel obtainable in Japan. The engine did not quit. It was just down
on power. Total running time then was about 50 hours.
I don't know what alloy they make these seal spring from
but it has been suggested on here that they be made from Inconel.

Jim was adamant in maintaining the Iannette ceramic apex seals did
not break.

The new rotors for the Renasis engine have better internal cooling
for the apex seal slots with small fins in the apeax seal slot area. 

The other engine is still going strong.

BTW this is a good picture showing the peripheral port.
Sorry about the color. 

Also BTW my scanner has gone to pot and I just
bought a replacement. I am also thinking of getting a Sony Mavica
FD73 640X480 with 10X optical zoom digital camera. Any pros or cons?
