An another power source for Pegasus Acro was prepared, OS 46 LA with YS pressurized fuel controlling regulator system. The regulator body invites some complicated and crowded pipe application, but still it is worthy for burdening enough especially on this kind of maneuver model.
Ordinary richer needle valve setting for fear the lean condition after an ending half is a mundane affair for YS pressurized fuel regulating system.
The key to success of setting it is simply the angular position of the regulator with satisfying mixture, idle to middle and middle to hi.
The difference of motor's weight causing the discrepancy of CG point would be compensated by moving battery position including replacing different sizes. No easy way such as burdening lead weight is unacceptable.

YOSHIOKA Pegasus Acro is now ready to fly, precise adjustments were done in detail. The motor for acrobatic flight must be suitable with stable fuel supplying circumstance such as continuous pressure under adequately regulated control.
Tuned pipe is omitted, YS 45 FS is my choice this time, relatively heavy weight invited some anxiety on the CG point, but the additive of one more elevator servo has met it adequately. Adjustment of the point within 5 mm depends on the burdening point of the battery as usual. Very kind description about the setting of the moving wings is helpful so much.
This tiny model airplane but well designed based on the true ability as a former World Champion in F3A field has enough potential to supply me some tremendous datum from now, anyway, I must bare in mind to continue this worthy one as long as possible.

YOSHIOKA Flash Pro 45 started yesterday. The basic constructive designing resembles a former build Pegasus Acro for both wings and fuselage. The principle to fabricate these model airplane is the same, paying desperate efforts not to distort or to twist especially the main wing in any direction, of course the accuracy of fuselage is the same. Poorly destructed model airplane could be flown by adjusting the trimming the moving wings, but difficult to be controlled following to the pilot's desire. Both good designing and good fabrication could contribute to the better bare characteristics of the model airplane. However better improvements might be done on the controlling Radio and Servos with precise and sophisticated mixing technology, the principle of Science in Aerodynamics does not change, once obtained bad habit innately by ill-fabrication never disappears. So, it is said here, "The more precisely accurate fabrication, the more candid flight could be supplied to the pilot.".
As for my future construction, next one would be also YOSHIOKA Sunday Alpha 50 and follows my destination, YOSHIOKA Bingo F3A, both of them are prepared and waiting for my determination. An effort to be exerted in my Hobby World is somewhat far harder work than my previous occupation.

As the next step this year, a kit box of YOSHIOKA Flash Pro 45 is opened and shells were separated from the base plates this morning. The kit is constructed with many small parts that threats me as to hesitate to start. Adhered rubber band denatured because of long period of time were carefully removed.
Though the wood cutting method is not recent LASER burning one but conventional, the accuracy of sawing is good on both balsa and piled hard wood. The selection and distributions of balsa materials are ultimately adequate and the degree of distortion and bending as a natural phenomena are very slight, the kit quality is excellent, second to none. So, the execution of this model is fully dependent of the skill of the builder. Best care and concentration must be exerted not to make any distortion for all the steps. The better the more accurate.
The motor to be burdened would be one of the most reliable and powerful one, YS 45 FR 2 cycle with Hattori tuned pipe, the propeller for this condition should be a marvelous Grass Fiber Polyester, manufactured by Akizuki Product 12-7,5.
I would like to continue the principle, participating the contests not with a professional made sophisticated beautiful stunt model but with a individually self manufactured model. Do all by myself what I can do on a model airplane.
I hope I could be an applicant for F3A Certification Exam this year with this Flash Pro model.

Flying tail linkage work on YOSHIOKA Pegasus Acro was over before long. Though the basic structural vulnerability of the tail stabilizer has been making me so anxious, the availability of this construction might perform good maneuver, so my opinion was changed after checking the backlashes of the completed moving parts.
But, any lough landing or over loading dangerous flight are inhibited, weight reduction method by making halls are done every where in this Pegasus leading to some limit vulnerability as a maneuver model airplane.
Ailerons linkage and fuel tank fixing works are remaining now, just a little bit works.
Very simply designed as Pegasus is, this is not a trainer plane for laymen but a specific purposed excentric Acrobatic plane for an experienced pilot.
Handling with the best cares, I hope this Pegasus Acro would last me at least 300 flights from now.
