One thing that I have learned from all of this is to be critical early, question everything, and never take things at face value. This will be a good conversion when done and I am very excited to be working with Verner and Scale birds on a safe installation.
I was reading the specs on the 9S some time back and your RV8 radial came to mind. I didn't know the 9S was that new to the market. Big advantage being higher torque and no PRU. And the sound!

AWESOME!! I got the privilege to meet you and see your RV8 up close when we gave a talk at your local EAA chapter about flying to Cuba a few years ago. Seeing the quality of your work I know this will be a super upgrade. I can't wait to read about your progress.

What's the diameter of the Verner?

Any difficulties anticipated with the change?

The diameter is 1.54 larger than the Rotec. Luckily I built that wiggle room into the cowling. It will fit with no mods.

This project rates up pretty high on the "cool factor". I was following the original engine pretty closely.

I'd ask how performance was affected with the larger frontal area, but I suppose there aren't many 135hp RV8s to compare against. Not that it needs to be the fastest when it's already the coolest RV8 around.

I would get a constant cruise speed of 145 KIAS with the Rotec at 85% power. I'll have a little bit more drag with this installation, but am expecting a bit better in cruise and a much better climb rate. GT Propellers will have to make me a new blade to handle the new engine.

Maximize the "cool" factor by having them design a 3 or 4 bladed prop for your airplane.

If you pay for it, I'll do it . BTW I remember your talk at our EAA chapter. It was great meeting with you and hope to again some day.

good stuff Flyboykelly

Was surprised of hearing so little about the coolest -8 on the planet. That explains
I'll sure be following your progress, but will not be able to comment or like any since I'm not a face bock
Thanks for all the info, pretty interesting and exciting.

PS
The Verners have a pretty good reputation, was considering the smaller 3 cylinder for the Hummelbird... moved on since then...

Is the 158 HP @ 2400 a continuous rating?

Can you go to a higher rpm for more HP? Maybe a 5 minute rating......
