Swiss made DOLMY Stopwatch has completed safe and successful so much!
It's far from ugly work but like professional one.
Because I have no experience on this kind of work, I wanted to send it to the professional person in Kanto area, he refused to do that if the movement is included being afraid of fracture in transits.
Such kind of accidental destruction might happen while transports especially on the precision devices, have I once on a German Synchro Comper mechanical shutter from Tokyo.
This is why I determined to do the work by myself without disassembling the chronometer.
I must appreciate from the bottom of mind Mr. N**ai in Sagamihara city, but for his help to share me a precious parts, a shield glass for DOLMY, the work could not be accomplished at all.

Main wing construction
The main wing weak part is connection portion in Pegasus, according to my experience in the former model Pegasus ST, 100 flight invited some irreversible backlashes at the connection between aluminum pipe and holding holes because of the vibration of motor combustion including the stress while maneuvering, both phenomenon occurred, enlarging holes and thinness of Aluminum pipe.
The holding holes should be fitted tight with keeping some smoothness for insertion and disassembling, so to speak contradictory conditions must be satisfied.
I just imagined to apply Microflon, micro grain Fluororesin powder, in the wooden holes intending reduction of sliding friction.
2 mm nutters would be invested in flying tail Horn portion to make them tightened firmly.
These kind of trifle attentiveness and ingenuity are indispensable for the better maneuver flight.
As Dr. Peter K. Thomas in UCLA said, "A trifle thing might be trifle, on the other hand, piled trifle things are not trifle but worthy enough!".

Escape habit
Some precious descriptions are scattered in his explanatory texts that cannot be written if he has not enough experiences and does not establish his precise technology and contributing phylosopy.
By the way, the Stopwatch is not mine but is committed to be repaired by the retired professor in the Agricultural division a few year ago.
From the beginning I thought it impossible to find out because of so specific and rare item, so it has been throwing away for long time before seeking the parts so consistently, but made a effort, did I a bit. Physical property innately I have, escaping habit might be a reason, I don't deny.
Consequently, I could come across with the seller in the Web Site the day before yesterday, as I have received an information to send me a precious part, it would arrive me at hand tomorrow. Probably, the professor must have forgotten the fact to have given me the item or he might regard me as an unreliable person?
I would like to be recognized by him the truth that there exist a strange person wearing persistent commitment in the world.
Any way I hope he would receive the repaired Stopwatch with surprise, pleasure and smile tomorrow, because he is the very person for not only me but for all his graduates of the University to be loved with the deepest admiration.

Confusion
TOYOTA Caldina AZT241W has covered 150,000 km and she makes me feel some problems in motor and trans axle mounting rubber insulators. Bounce shock stress is conveyed relatively directly. The advantage of this condition is surer steering feel because the heavy masses of the motor and the trans axle is connected directly on the nose portion. I can discern the noise of valve hitting movement while driving meaning the loose of the insulating effect.
The time is come to be replaced as the periodical replacement parts on the motor mounting insulators.
Then what will happen if the necessary maintenance is not performed?
Direct stimulation would be transferred onto the strut upper mount and rubber part would be torn off leading to the dangerous result.
Remember that all the wheels are replaced into new ones costing 100,000 yen the other day, huge expenses. I should use newly replaced tires more two years covering more 50,000 km to meet with the value for the expense.
On the other hand, my son is going to sell his VW Golf GTI model without any problem because he bought HONDA Step Wagon for his convenience to carry around his motor bicycle while long trips.
As an another choice for me, I might use Golf instead of Caldina as a matter of fact.
Now, I'm at a loss how to chose the way standing on the cross roads.

Pegasus Acro on the way
The fuselage and stabilizers, vertical and horizontal were completed for newly building YOSHIOKA Pegasus Acro.
As mentioned before, the designing of main wing is modified to be available for both original aileron style and Flying-Wing, the parts, 4 investing ultra thin radial ball bearing 15-21-4, #7602 and two pieces of 15-13-400 carbon tube.
Considerable expenses make me satisfied.
So, my idea for Flying-Wing in ordinary stunt model is going to be tried on Pegasus Acro. Mixing procedure on the transmitter might be complicated but interesting. The fixed horizontal stabilizer without elevator should be newly fabricated in addition.
I hope I'll enjoy several attempts on the newly constructed model airplane, because this is my own world not to be invaded.
The motor to be introduced would be OS 46 LA with YS fuel pressurized regulating system and the servos would be E-Max 9258 metal geared digital.

A new Idea!
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!

Flying-Tail in Pegasus Acro
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.
