Considering about Flying-Tail construction in Yoshioka Pegasus Acro led me an inspiration the trial on Flying-Main Wing. Recent carbon pipe central connective main wing construction might show me the possibility of FMW idea!
Looping and rolling are done only by the main wing instead of elevator and aileron, interesting! don't you think?
Also sophisticated Radio might it possible set up Flying-Wing program!
Eliminating moving part, ailerons on both side the main wing themselves move and change the angle of attack independently, the fixed horizontal stabilizer loses elevator leading to the elevator servo elimination.
As I'm keeping 50 years old trainer airplane Ikuta Flying Tiger low wing model but fuselage and stabilizers only, the main wing for this would be newly constructed inviting upper idea immediately, motor would be 32 or 25.
An abstract of designing is already rosen up in my mind, I will start immediately to draw the mechanical construction now.
If the result of this trial attempt were favorable, the idea would be introduced in F3A competition models in future.
I wanna see what'll happen ASAP!

Yoshioka Pegasus Acro invites Flying-Tail design as it does, the supporting construction is very important, durability, accuracy and 3 dimensional backlashes.
Original designing is 8 mm dia. inner & outer sleeves Aluminum construction, it won't last 100 flight under 45 class grow motor vibration however some grease lubrication might be done well there, destructing energy caused by combustion phenomena should not be made little of even model small motor.
Because of the upper reason, I made up my mind to apply miniature ball bearing on the necessary portions.
Though I tried to follow the original design following instruction manual, only this complicated part was modified as my own. Weight increasing by the changing is very slight not to affect the original performance.
Stabilizers would be completed soon and a residual work is main wing construction, paying the best concentration not to distort at any rate.

I started to construct YOSHIOKA Pegasus Acro today, and initial step for fuselage is glued up. Wooden parts are well cut by means of LASER system.
Strength and redundancy system are well considered by the professional designer, many small parts are scattered everywhere intending weight reduction.
Very gentle handling is required by some experienced and trained pilot after completion, so this model airplane is not for a beginner but for adequately experienced one.
Pegasus Acro would makes a certain promotion to be controlled well as to participate in the future stunt contests. Very light and relatively large wing area design shows incredibly specific flight.
Because have I several suitable 40 class motors prepared for Pegasus ST model, I'm looking forward to try them on new model.
By the way, Pegasus ST was destroyed after 3 years using by my trifle mistake, vertical, low altitude and motor stop lacking fuel supply, I should not get riding well too much. Loosing power with low altitude leads to a critical crash, this is the same as an actual airplane.

I've realized that the main needle angular position on Solex 34 PICT 3 carburetor has some sharpened difficulty that has some relations with automatic choke control. As the 3ird party manufactured carb. used Bocar is mounted in my VW 1302 Super Beetle, a principle to adjust the original position 2 and a half turning back from the tightened angular position is not always meet with mine. Probably, former user of this Bocar might have tighten too much in, so the needle valve hole must have been enlarged illegally.
Consequently, the angular position of main needle valve should be decided by my cut & try method repeatedly, very small and keen adjustment is required under this condition, not impossible but available. 470 degree turning back position of mixture control screw is my setting as a matter of fact.
Though the procedure for it relies on my sense and experience, mainly rely on exhaust smell, too much lean mixture produces excessive Hydro-Carbon and too rich Oxidized-Carbon instead. Of course, spark firing timing and timing acceleration construction, both vacuum and centrifugal has much to do with the motor's combustion.
Because have I a struggled experience on Weber 40 DCOM side draft twin carburetor as long as 10 years originally embedded in Peugeot Talbot 205 Rallye, the single carburetor adjustment is not so difficult task for me.
With mechanical Weber side draft twin carburetors, Regular Government Continuity Inspection had been passing instead of Private. Experienced mechanic servicemen should know how difficult it had been on Earth?

I always say to myself and to my son, only experiences make a man. Asking anything to others means being stolen precious and indispensable treasures by the others.

Ordered brake rubber cup parts arrived from Tokyo for my VW Super Beetle 1302 costing 5,292 yen including Tax. Judging from ordinary common sense for these parts, ten times price, however they are unlikely as 45 years production air-cooled Beetle, how come?
I must inquire the rusting phenomena on the brake cylinder inside wall first, though I didn't neglect to change brake fluid every 3 years, occasionally, honing procedure must be done if the wall might have substantial oxidized deficiency.
Considering conscientiously, the cylinder inner surfaces should be processed by means of Chrome plating technology in to like a mirror, don't you think?
Because I touched everything, imagined I some fine omission work before I begin to change rubber cups into new ones.
In order to prevent brake fluid leaking, I do insert a DIY 1 mm thickness round rubber pert between the rubber cup and the bottom of a sliding pusher part, counter-measuring 2-step stance.
Let's see what will happen, reporting later.
