Default Prop

How do these compare to the 375RV that I have on my 10? They look similar except the tip design, mine is a sharper point.
And BTW I'm super happy with my whirlwind. Everyone comments on how smooth it is.

The HRT375 is about 55 lb compared to the 42 lb for the 300 series 77. Thatís because the HRT propellers use an old McCauley based hub system and the 300 series is an all new Hub platform design. It packages smaller allowing it to be lighter and to fit better in the spinner (no more blade ferrules showing through the spinner blade cutouts). The 300-77 was designed specifically around the RV-10/IO-540 engine airframe combination. PIREPS say the 300 series offers better takeoff and climb performance, smoother operation, and no sacrifice on top speed.

I'm a gonna be needing one of those for my RV-8. Not ready to hang the engine yet. But, hopefully in about 6 months.

I'm wondering how far out should we be ordering? What kind of delivery time? And, What are the terms?

I order a 300-72 for my -8 build recently. Quoted lead time on initial contact was 4-6 weeks. In actuality, the prop shipped about 2 weeks after I placed my order; all told, exactly four weeks passed from the time I placed the order to the time I cracked open the crate at home. A $1000 deposit was required to place the order.

How does it compare speedwise to the Hartzell F7497 BA?

There is an article in January 2021 Kitplanes comparing the new prop against the Hartzell. It is possible that the Hartzell prop is F7496 BA and not the newer F7497A.

Yes, I wonder why they have no data or pricing for the RV-10 prop. I hope they get that up soon.

Default CG issues

Very intriguing. Would love to put one on the F4 (four cylinder rocket) I'm building but I actually will probably need the up-front weight for CG purposes. Won't know for a while if this is a real option for my (or similar) builds.
