Albeit slow, some more "design as I go" progress.

The 1/8" diameter music wire for the landing gear just did not look strong enough, so upped it by 25% with 5/32". Much stronger and it turns out the wheels taken from the unflown Alpha 40 that is no longer needed (thanks to RF!) actually fit better as they as made for that diameter wire.

Also cut the slot in the fuselage top deck for the rudder post. Best idea provided to keep its length aligned with the motor thrust line was to run an available thin wire from motor shaft to tail post. The tail post used during assembly has not yet been cut to accept the stabilizer, so for picture purposes, the stabilizer was placed on the rear deck with the rudders' locking tab holding it in place. The rudder and elevator were also hinged and were blown about a bit in the light wind.

A quick check on the CG showed the plane looks to be a bit nose heavy. That's good as work (and the increase in weight) remains on the aft part of the plane, including the tail wheel and covering the tail surfaces.

Next up on the RF version will be the control horn detail as well as the wheel replacement to reflect the real FBB. Jury is still out as to whether the servos will get mounted back by the tail feathers or in the more traditional location with long push rods, so no RF modeling on that yet.

Work continues to be crazy busy, plus lost a little focus for awhile last week as one of our employees that I talked to every morning day passed away from a heart attack on the factory floor later in the day. Was a long week.


Enjoy a safe week.

Thanks U.T. Hoping to get it airborne THIS year
He usually came to my office in the morning for coffee, including that day, and the memories are still very fresh. To your question, I believe his was in his mid 50s. Will obviously learn more at the funeral this Friday.

Well keep at it, would love to hear about and hopefully see the results (via vid.) Mid 50`s wow!!, just a reminder to us all, of how fragile life can be

My brother in law suffered his first heart attack at age 29. 10 years later, he's had 3 more attacks, 9 stents, and a quadruple bypass. Just goes to show you never know and disease doesn't discriminate by age.

Be safe UT!

Squeezed in some FBB time recently, and having been struggling on what kind of tail wheel I wanted. Really wanted a coil spring, and recently the answer was provided as how to modify the Sullivan TW assembly I had on hand with some scrap aluminum and JB Weld.
So, now more to 3d model.

Enjoy a great and safe week!

A little more time on the FBB, RF & RW

The RW plane is just about to the last stages.
Tail wheel assembly was added this week, so the plane can finally stand on its own three feet, as well as the first pass at the top hatch, with a small cooling air intake, and a rough pass at where I want to place the RX, battery & ESC.
After the stab and fin get attached to their true positions, it should be just the control linkages and servos...

For the RF version, got the tail wheel assembly modeled and mapped, and well as changing to the real wheel types that are in use. Not always easy to see bottom views in RF, but as long as I was adding some detail, put in the actual housing groove and screws the real tail wheel assembly has.
Physics are keeping up with the RW model as its assembly progresses. Presently the RW model has a 13x4.5 APC (multi rotor) prop, but flight tests in RF show that seems to result in a little too much torque. so will probably go with a 12x6. Have not run the Power 32 and battery for awhile, so its time to get some new data using the 12x6 so the physics can get updated.


Enjoy a great weekend and week.

Thanks guys.

Tail feathers are now glued on, so it's pretty much down to the control linkages and servos.

After more consideration, am going with a servo on each aileron vs the inter wing linkage-- ah, 3d modeling change ahead...
