Can't recommend this engine enough. The power is unbelievable. UNBOGGABLE! Worth the bucks!

[Tom Burgess]

no pump issues?

[Tommy]

No not at all; perfect. Cant see I will have issues with pump. Runs like a train and idles like a purring pussy cat! Running with no muffler pressure.

Unboggable eh. Sounds like its time to increase the pitch - 16 degreeezz!!

Without wanting to dampen your spirits at all Tom, I have heard of several engines developing issues with the pumps after some use.

I never got on with the older SXH pumped engine (the pump being the problem there), however, my experience of the new HZ pumped engine (in three other people helis) has been very good - really good power and very smooth!

Just be aware that this situation might not last if the pump decides to start playing up - until then, beat the crap out of it

Cheers,
Rob

Thanks Rob; Ripmax are very good if you ever got a problem with your OS and I know a good guy there should something be occuring!

Maybe its the extra feed of muffler pressure thats causing peoples pumps to go funny; who knows!
