Air-cooled VW 1302 Super Beetle "Thrust"

The thrust angle on air-cooled VW 1302 Super Beetle has also adjusted, establishing zero total toe value, thrust adjustment invited much difficulty if compared with SXE10 TOYOTA Altezza that has capable enough adjusting points. As a matter of fact, the left side hub case movement 2 mm backward eliminated all the discrepancy.
The establishment of thrust is the most important requirement to drive a car in comfort. Let's imagine some Billiards game, any deviation of just a little of course results in failure to fall the aimed ball. On the other hand, the axis is to the point, it goes on the course to the falling point.
The importance of the thrust is the same in F/F or AWD models, because the direction of the driven car is decided by the thrust of the rear total toe vector direction. In addition, the discrepancy of the thrust is precisely adjusted by keen sensor equipped mechanism---the driver's corrective function under unconscious. This is why we drive a car relatively long distance, not muscle fatigue but nerve tiredness.
Though it might be some illness to stick too much to this kind of trifle thing, I would continue to do so because there exist obvious difference between Zero Thrust car and others.

Modify GW 30cc MXS-R

As mentioned before, Gold Wing 30cc V3 series model MXS-R is under construction modifying it's tail moment 75 mm longer than original design in order to adapt into F3A competition use. The task is not so easy as imagined because there were many parts to be corrected, twisted, vent, distorted in all the wings in addition to the fuselage construction. Consequently, it took me relatively long period of time including motivating myself to proceed the work, not so interesting nor fun. The rod type plastic hinges must not be strong nand tight to support stronger forces when laundering, and the same airplane had ugly flatter phenomena when I saw last year. So, I have applied additional hinge points in adequate positions for the fear of awful flatter, I don't want to come across with such kind of disaster, yes, damned disintegration!

Thrust in SXE10 Altezza

I have realized after establishing zero thrust in SXE10 TOYOTA Altezza that even a slight value of wheel alignment discrepancy as to 0,21 minutes(12,90 seconds angle value) causes some indescribably unpleasant steering feeling, le the thrust angle has much to do with the straightness of the vehicle. Hmmm---, there exist several difficulties, for example, rubber bushes scattered everywhere in the axle construction designing for preventing noise and vibration from the ground and motor crankshaft knocking stimulation, yes, these materials has inevitable physical properties, changeable permanent elastic strain, viscoelastic hysteresis. They are all the criminals that prevent us to adjust and set up the axle constructive geometry and wheel alignment in the critically precise condition. It goes without writing there that the tires has also much to do with the upper condition, because they cause some uneven polarized wear according to use in unfavorably bad environmental condition. So, we should check and correct periodically the axle constructive condition if we desire to drive your vehicle in comfort, the importance is the wheel alignment.

VW1302 bumper protector



Bumper protectors were set in places on the rear bumper end for preparing the 2 years periodical Legal Inspection according to the Road Vehicles Act next spring. This the measures of an accident that happened in the past with a bicycle,  a miserable bicycle driver dragging it's wheel sandwiched between the cavity Beetle's rear fender and the it's rear bumper. So the thickness there was specified below 35 mm, the value should be the bicycle's tire width? As for my VW 1302 Beetle, the original bumper was replaced into a poor quality ones for front and rear when face-lift had been done. Lack of the end length invited 45 mm space there, this is the reason why I applied plastic ugly protectors on the rear bumper. Though have I not a little regret after that, must I follow the Legal Regulation anyway.
Beetle's carburetor repair kit and a diaphragm fuel pump were ordered together with bumper bolts, the positions of the fuel inlet nipple and outlet one were at different relations compared with indigenous one, I knew the construction after breathing in or smoke was blown, care must be taken on the rubber fuel hoses arrangements including adequate length promptly.

Below 5 degree Celsius today

2 cycle 30 class modified "Majestic" ARF model is now undergoing to change my initial planning from GP into EP. For the convenience to replace Li-Po batteries, the original fuselage construction is also modified cutting it's upper part just infront of canopy portion. According to opening this part, any reinforcement would be required. Some carbon fiber square pipe would be applied around the upper hall.
About OPTO ESC Futaba MC9100A, this production is exactly as same as OS 100A ESC OCA-1100HV, so Futaba programmer MCP-1 is applicable to OS ESCs. This information was obtained by asking to OS customer service division.
Remembering back the starting point a year ago, my planing to invite GP were obliged to translate into GP by several factors. Because, Ogawa precise manufacturing company is using the test flight place that is the same place as mine and the newest information in F3A field are brought to me unintentionally as a matter of fact, this is why I have been moved my original planning from GP to EP, in addition, there were many opportunity to see the excellent condition flight of a seed player.
Remembering the past 30 years ago, I was flying with a person who had been a champion in F3A field belonging with Futaba researching and developing division, so I was and I am enjoying my R/C life in the luckiest environmental condition.

Gradual transition

Typical winter season has come this morning in Kinki area, the Continental high pressure comes down and covers here with Chills, so even in the day time the temperature outside does not come up to 10 degree celsius.
Two of EP model airplanes are under construction and soon they will be put in the air, gradually my power source is in transition these days. Kypom Lithium-Polymer battery for F3A with 10S have arrived today.
This winter season would be desirable and interesting interval of preparing for the future EP flight in the next Spring season.
