I am concerned. My new SxS is pretty much complete & test flown. I am very happy with everything except...POWER! Remember I am used to flying a very light 447 AC.
My climbouts leave me wanting more. When cutting back on the throttle during cruise , she sinks. My focus is now to make her more efficient.
According to some, The Prince prop put the Warp to shame. Joe Souza, who built my engine & redrive, originally recommended this prop also. I couldn't get him on the phone yesterday.Does anyone have Princes' phone #. I know it's a long wait , so I better start talkin' to him! This is an easy area to try & get perfomance increases , so I will start there.
My EA-81 appears to be doing it's best. I chose the 81 over the 22 & 25 due to less weight. I could spend alot of money trying to get more out of it or just decide to go with a larger engine right off the bat. Before I order a custom prop, I better make that decision first.
Weight.... I look at my machine & think.... Where can I trim weight?
There are just not many places in my mind.
Another area that is pretty easy to try to increase performance would obviously be the rotorblades. I am hoping to be able to test a set of Dragon Wings at ROC. Erie & Mike.... are you reading this? I think I would need a 27 or 28' set. I could save on shipping for sure!
How about rotor RPM's. With 10 gallons of fuel & a 100 lb concrete passenger, my blades are spinning between 290 & 310. This is about 150 lbs less than my expected max gross( I want more fuel & more pass. weight ). Does changing rotor speed (pitch) do anything for performance?
I also wonder if I bite the bullet & buy a 912s, What would my increases be due to the fact that the engine is lighter.
I hope we can all use me & my machine as a topic of alot of dicussion at ROC. I can't wait to see you all .
Does anyone have any input here & now? Help! My head is spinning. It could be the coffee.
They were test flying a 2 place trike last night. 2 people with a 503. Less than 100 yrd takeoffs & amazing climb...... It just makes me think!
Ron, please be gentle & try not to hurt my feelings. That is if you plan on test flying it. Oh, don't forget to bring scratch & dent money!
