Thanks Stu.., great video..! Wow, after 7 RV's your favourite is the 4..! I couldn't agree more as I have built only 1 RV... and it was the 4..!!!! After 5 years of faultless operation I still have that wow moment every time I fly. So 215hp in a 4..? Ok , so, I was considering building an F1 Rocket, but with the numbers you achieved, why would I..? Great summary of your build and its issues and results. Thankyou. Fly safe all, soft sky , hard ground.
Good seeing you Stu and thanks for the update! Yah....knew things were getting busy for you even back in the summer when you started to train....u had the infamous helmet racoon tan which means a lot of time in the sun under the canopy. MOST importantly was holding steady for your word on the -4, compared w the -8. Bingo! HUGE moral bump for me to hear this especially considering how many holes I have to drill out in this kit🤣 All worth it with your input! TY!!👍
Welcome to the rocket performance world. My Vne is 240ktas on my harmon rocket 2 and cruise at 200kts on 12.5gph. Your airplane is going to be beautiful when done.
Wow i dont undersand but it has always been work for me to understand math type logic.im not arguing but i always thought never exceed which i gave wide birth to was indicated wich i think means the speed the aircraft feels like if you put a finger out the window.Someone please help me understand.
Always a bit of extra inspiration on my Sonerai build... The NCMs version of the RV4. Would love to see more snowbirds stuff if possible. I was hoping I would have ended up being a tech with them.
I would love to provide more training videos however we're too busy in cockpit to get anything besides official video - the public affairs guy takes care of most of it. Plus most video belongs to military once filmed so it needs to be considered appropriately.
Your videos are very interesting. I like your hangar, especially the lifting gates. Could you shoot in the next video in more detail the mechanism of these gates-books.
Any idea what drives VNE? Could it be just conservatism due to variability of kit-built aircraft? What would it take to increase it, Van’s inspection, structural mod?
Hi you mentioned in your video a ramp for the outlet airflow . Would you have a drawing of the installation? How efficient is it on drag? Thks, Mathias, RV6, France
Yeah it seems like there are 2 schools when talking about this so both sides are correct. Most regard VNE as flutter margin so its TAS I believe. This stems from fact that most airplanes do not have TAS indication until recently. On my RV4, the indicated airspeed will turn red at about 168 kts at 9000 MSL which equated to 182 kts TAS.
@@stusaircraftfactory6592 opposing solo, that’s awesome. I had a friend Micheal Cliche who was opposing solo when he flew with them back in the mid 90s. Stay safe.
Great question. I always answer questions like this with honesty and an actual answer hahaha. I prefer the RV4. As far as building the RV8 is way easier RV8 has more luggage space RV4 Landing gear config is better RV8 is bigger for passengers RV4 is faster and better handling RV8 space on firewall is better Thanks is for asking
@@stusaircraftfactory6592 Has the Factory ever considered a "basic" RV4 project (eg:O-360/180 F/P day/night VFR) to showcase what "bang for your buck" can look like ?
@@jtropfenbaum7931 Funny you should ask. That was the original intent of the RV4 project but it evolved into performance. I’d love to do that if I could find another kit . Thanks for asking
The issue comes when its time to descend. To do that I close the alt air bypass, pull power back and push prop in a bit. You can keep it under VNE no problem
They are very fast…and beautiful…but when compared to the SR-71…ahhhh..not so much…or space shuttle…17,000 mph…what is fast….speed of light….that’s fast….beat that with your Tesla Plaid….🤣🤣🤣

Season Greetings to you and your's Stu.
Wow, that is a busy schedule.
Thanks for the interesting update, what a weapon!

Thanks for the update Stu, I’ve got my RV4 fuselage in the jig and hope to put skins on in the spring here in Missouri.

Yeah awesome. So impressed with this RV

Congratulations! Nice hangar.
Thanks for mentioning that VNE is true airspeed. That caught me once...

Akura Autobody painted my GTO many years ago, the owner is an ex military painter. If they’re still there, that is. They did a great job!
Your videos are very interesting. I like your hangar, especially the lifting gates. Could you shoot in the next video in more detail the mechanism of these gates-books.
What lifting gates are you talking about? Not sure what you mean
@@stusaircraftfactory6592 Those that close the hangar are large. ;-)
Make sure to have a build your tank section for your young dude!
It would help to clarify VNE in IAS (typically) and your cruise speeds are in TAS.
At 9500 the IAS is about 160 kts I think. I’ll check next time. VNE is TAS to be clear.
Any idea what drives VNE? Could it be just conservatism due to variability of kit-built aircraft? What would it take to increase it, Van’s inspection, structural mod?
It’s aerodynamic load and flutter margins as far as I know
I’m looking for more info on your red intake setup, I can’t make out the name when you say it. Very interesting, thank you!
Rod Bower intakes - really amazing
Hi you mentioned in your video a ramp for the outlet airflow . Would you have a drawing of the installation? How efficient is it on drag?
Thks,
Mathias, RV6, France
Sure I’ll find a pic but it’s similar to what’s installed in RV8 if you’re familiar. It’s basically a curved ramp at airflow exit.
Thks
Surely VNE is an indicated speed. Hence the red line on the ASI. If you are referring to the critical flutter speed, then that is another thing.
Yeah it seems like there are 2 schools when talking about this so both sides are correct. Most regard VNE as flutter margin so its TAS I believe. This stems from fact that most airplanes do not have TAS indication until recently. On my RV4, the indicated airspeed will turn red at about 168 kts at 9000 MSL which equated to 182 kts TAS.
Thanks for the update Stu. Hope to see you in Debert end of August. What number Snowbird are you?
9 - opposing solo. Hope to see you also!!!
@@stusaircraftfactory6592 opposing solo, that’s awesome. I had a friend Micheal Cliche who was opposing solo when he flew with them back in the mid 90s. Stay safe.
Happy holidays.
Do you have the standard 16 gallon tanks? I wish my builder put the -6 19 gallon tanks when he built mine..
Yup 16 gallons. With 32 gallons however still good for almost 3 hours plus reserve. I’m planning an aux tank in back
@@stusaircraftfactory6592 is love to see the details when you do that aux tank. How many gallons are you thinking you’ll do back there?
@@thomasaltruda1243 probably fit in pax seat so less than 10 gallons prob. Easily removable for long xcountry solo flights
You know the RV4 and 8. Which do you prefer for all around considerations ?
Great question. I always answer questions like this with honesty and an actual answer hahaha. I prefer the RV4.
As far as building the RV8 is way easier
RV8 has more luggage space
RV4 Landing gear config is better
RV8 is bigger for passengers
RV4 is faster and better handling
RV8 space on firewall is better
Thanks is for asking

Any updates on that belly exit pan at 3:52? Is that a homemade piece?
I still haven’t got around to installing it. I’ll take a look at it today since I’m just finishing up fairings right now
Great stuff! Whats the name of that filter with the bypass?....

Too risky flying that close to VNE, zero margin!
