RV10 Real World Performance at Various Altitudes

[Traash]

FL 250
IO-540, 2 Slick mags, 75* ROP for max power.

Flew this profile to test the RV-10 service ceiling. Conditions were optimum. Wouldn't necessarily be able to get this high with sub-optimum conditions.Not much additional benifit flying above 20,000.

Refer to picture for conditions.

My 10 will get about 1 gph less than the OP example running ~30 deg LOP, 2360, WOT - throughout those altitudes. Not sure why unless you're not running as far lean as I usually do. Not much difference in TAS for me.

How’d you program those tick marks on your trim and flap settings? Is that doable in G3X serup? Or do you have VPX or some other device that makes that possible?

Adjustable in the G3X menu..

Randy, what is your Surefly setting? FIX or VARIABLE?

Thx for info on G3X. SureFly is set for variable timing.

Thank you, to the posters. I always thought that some day I’d file ifr, swap in a mask (instead of nasal cannula) onto my O2 tank, and see how high I could get my 10 to go. But last year I went with Basic Med and let my second class medical lapse. So now I’ll have to live vicariously, thru you guys!

I generally run my RV10 at 21” and 2300 rpm LOP. I reliably get 170-175 TAS (depending on weight) at 10.5 gal/hr at 10,000 ft. TAS starts to decline slightly at around 15,000 ft. I have a Barrett 540-X 290 hp with a Showplanes cowl. Don Rivera helped me balance the fuel injectors to make all cylinders peak within .2 gal. That was very worthwhile and not that expensive.

Don’t forget to try flaps zero above the mid teens, mine is faster than reflex when higher.

What prop are you running Robert?

I have the same engine and cowl setup as you but have the 3 bladed Hartzell.
I see very similar numbers to you (maybe a kt or two quicker) but I am only just LOP at about 12gph as I’m waiting on one restrictor from AFP still to finish my balancing. I have one slightly lean cyl which peaks 0.5 gph before the rest.
I imagine I’ll lose a few kts at 10.5 gph putting us very close.

Cheers

Interesting.

This is new to me. So flaps 0 instead of -3 above 10K? What type of changes are you seeing?

Thanks,
