No, two-factor authentication is not required for Groups.io sign in;?it is an optional feature that you can enable to add an extra layer of security to your account, but you can still log in with just your email and password if you choose not to set it up.? Key points about Groups.io 2FA: - Optional:?You can choose to enable two-factor authentication on your Groups.io account.?
- Added security:?Enabling 2FA provides an extra layer of protection for your account.?
- Access method:?If you set up 2FA, you will need to provide both your password and a verification code (usually sent to your phone) to log in.?

The following is from this forums files section:
We, wife and children of Callbie Wood, appreciate the condolences on the forum about
Callbie's death.
He was a dedicated flight enthusiast.
We will continue to offer plans for his original design, the four place "Fourunner", and
metal wing plans for Wittman's Tailwind. You can contact us via email
(cfw1927@...), telephone (252-243-6708) or mail at 10717 Old Bailey Hwy,

Hi Greg, ??? I had a similar situation on a different plane. What I did was to stitch it at the base from the underside.? Don't know if that would work on a TW. Al
I'm using stewarts for my fabric system and I'm having difficulty getting the fabric tight at the 90 degree junction of the vertical stabalizer to top fuselage. In the image, the area of concern is where the white tape is. Can anyone help me that has figured this out. Up till now, I can only get the fabric loosely installed making a visually and aerodynamically unfit finish. Thanks

Jim Rust,
Your estimate was perfect. I reduced pitch 3 degrees and now at ~7500 MSL WOT exceeds 2700rpm so the flightaware plot is at less than WOT at ~23¡± MAP and about 2680rpm. Average ground speed 195mph. I plan to add back ~0.5 degrees to the prop, tape the gear leg fairings, put more paint on the spinner and hope for at least 200mph WOT down low around 3000 MSL.?
Thanks again, Bob Wray
Bob
Your RPM is way too low and thus giving up a lot of take off , climb and top speed performance. As per GA200L propeller set up Instructions, ?WOT straight and level RPM should be 2700. With this setting your TW will easily reach 195 mph, probably
more. Plus take off and climb will be substantially better. At. WOT rpm is proportional to HP, more HP is more thrust, more thrust always =more performance.
Est. Reduce pitch approx 3 degrees
Tried and true method to measure performance is to compare fuel flow for a given speed
Jim Rust
Whilwind prop pitch adjustments:
Flew 1/2 hour today with a lot more pitch (26.1 degrees relative to new spinner back plate). This is approximately the same pitch angle I had last summer that gave me about 195 mph. Todays 26.1 degrees was with a different hub, relative to a
different backing plate, and was measured with a different protractor. Whatever the source of difference this is now (probably) too much pitch. Today WOT at 7500¡¯ ?gave 23.2¡±MAP 2400rpm and 191mph average stabilized ground speed flying 4 points of compass.
?This was without spinner dome.
Also
static rpm was only 1800rpm.
? I plan to make more flights including some lower altitude flights at WOT and less than WOT with spinner dome installed before adjusting pitch again. Currently I expect to target <25 degrees.?
Also, I posted a basic ad on Barnstormers.? Note that I may replace N115WT with a low and slow airplane that could be a primary trainer for my young adult children.?
Whirlwind prop (new whirlwind spinner going on now, see pic). Efficient cowl. Low drag wheel pants with nice gear leg fairings (taping them adds a few knots but I haven¡¯t learned to do it without making an ugly mess). A very nice single piece
of carbon fiber that provides both sides wing root fairing and runs across the fuselage at the back of the windscreen that is a work of art. Very smoothly built wings. Simple and light build.?
Those are incremental factors. The quantum leap came from Steve Wittman and his wonderful design. ?

Re: Brake Master Cylinder mounting question
Andy,
I did like exactly like your proposed setup.? When I did my first engine run I had two people on the wings helping to keep the plane from rolling.? Now, the brakes hadn't been broken in yet.? But, I went ahead and installed Matco's brake intensifier kit on the master cylinders and now it works perfect.? Even though the brake pedal rocks forward a little bit with rudder.? It isn't a problem.?

Brady, one of the key things to making the geometry on the pedals work is to keep the base of the master cylinder as close to the pivot point of the rudder padal I did this and when I press on the rudder pedal the brake pedal moves with the rudder pedal without applying the brakes, to get braking action I just use the top part of my foot to apply brakes like on a old cessna 172

Re: Brake Master Cylinder mounting question
Clement method, works great lasts a long time no issues with inadvertent brake application. I don't do hammerheads in the Tailwind so no need for much rudder except taxiing in a strong wind.?

The Clement method was to use a 5/8 square tube for the lower mount and weld a piece of 5/16 x .058 tubing across the bottom of the 5/8 square. I will try to remember to measure mine but I think the geometry on the Tailwind plans is wrong for the mounting point in relation to the length of the are. The arm does not need to be? square to the pedal, it can angle upward significantly.?

Gene passed away at age 95. Most probably don't know that Gene built airplanes with his son at Santa Paula Airport in CA. Glasair, I think a 3, and a Pitts or maybe a Christen Eagle.? I think Gene had heart problems and stopped flying.? A photo of him with Top P. in the EAA museum in late 80's can be found.?
Do a search "Movie Actors who were pilots." Gene is not on that list and the list is very incomplete. The list was much longer just after the end of WWII. Steve McQueen was at Santa Paula in his final years. Tyrone Power was a Marine Pilot in the war and owned a DC3 after the war.?
A friend taught Johnny Carson to fly at Teterboro in the early 60,s. My friend was on the Carson show in that era as was Art Scholl. A few years ago Johnny's log book was on display at EAA Museum. The book was open with a signature Earl J. Sollien. Earl was from Hamilton NY and was a couple or years ahead of me in high school. His father in law was a local pilot and taught Earl to fly. Earl was a EAA Member when he passed away at his retirement home in FL. Ed McMahon and Skitch Henderson from the early Carson shows were both pilots. Ed was career Marine Reserve fighter pilot.?
