Hi Guys

I have a couple of the weston .25 engines.

I have run one ready for installing into a combat hellcat.

The engine took 8 tanks at full blast just to stop it squeeking at tdc. and it has now become reliable ready to use.

I pulled out the restrictor in the exhaust silencer, it was pulling around 19000 rpm on a 7x6 master airscrew.

I think its still running in at present and I suspect it will continue to increase in power over the next 10 flights or so.

In summery it looks great but it takes ages to run in.

Good luck
