Just looked at Marks So-Cal pics. Anyone know what kind of pump this is?

Thanks,

I know

Its the bottom of my Raptor 90. Its a proto typ Cspec 91. It has perry pump mounted on the bottom of the back plate. Notice it is a single needle valve. It is possibly going to be a production engine.

It's a perry, they are coming out with a new mounting bracket that attaches it directly to the backplate. Looks like something is going on with the carb too.

Straight from the horses mouth! If you don't mind me asking, are you using muffler pressure too? This doesn't look like the typical CY setup, how does it perform? I love the look!
Thanks,
Jojo

muffler pressure is used also. It is developing awsome power. I only aprox 1 gallon thru it so far.

I am running a perry pump on my OS91. I am using the muffler pressure also as per the CY setup, do you need a checkvalve between the backplate and the pump like the perry instructions say? Are you using the T fitting to allow unused fuel to go back to the tank? One more question, All the info I have read about needle settings and I have yet to see anyone say how far to screw in the adjustment on the pump. Any insight would be appreciated. Thanks.

In God we trust, everyone else we monitor.

Hey Alan, I got some of those Airtronics servos and Li-Polys coming my way, I can't wait to try them out

I forgot to ask, do you know how much your R90 weighs all up with fuel?

fan shroud

In the new 90 it will accept the Cspec without any modifications. Boom is slightly longer than stock 90
