I would like to start this thread to discuss and compare results on the NovaRossi R61F and the R61F Speed/13 engines.
My son, Nick, has been running the R61F Speed/13 in the GP's ARf Dirty Birdy. I have just installed the R61F in my old Fliteglas Models Saturn from the 70's.
Nick's Dirty Birdy is a great flying plane and the Speed/13 goes like gang busters. Been clocked on radar at 147 mph out of a dive. My Saturn had an OPS 60 in it but the OPS is getting a little weak from age.
Hopefully we can get some discussion going on things like: rpm, tuned pipes, pipe pressure fitting location, props, fuel, glow plugs, etc...
I'm ready to put the pipe pressure fitting on my Saturn's pipe. What is the correct location on the NovaRossi 50400 Long Pipe? I saw a picture of one with the presssre fitting back quit a distance from the high point of the front cone. I was told on other pipes that the fitting should be at the end of the front cone (largest dia.). Any body have an opinion on the location?
Please don't let this thread get into arguments on items. Let's just tell everybody how we are doing things and what the results seem to be.
