Hi Wollie, die BMW het 105 perde, meer as 912S en met regte tuning en exhaust maklik 110.

Johan,

Jy verstaan verkeerd....... ons soek prentjies van die vordering......

Groete

Hi Deon
Ons is nou besig met die papierwerk oorlog met CAA, dinge loop stadig. Ek sal die naweek weer by Trevor probeer draai maak en weer "prentjies" kry en dan weer pos.
Jy moet solank spaar vir die conversion, moet gedoen word voor ons Oranje rivier trip

Hi IceAge, man ek dink hierdie projek van Air Hog is sssoooo n blink plan en skitterende idee, dat wanneer hy probeer foties vat dan groet sy kamera... "flash an all ek se"...DIS nou die rede vir geen foties
Ho-hum , ons wag dan maar geduldig...........

[Air Hog]

I can now understand Oupa-G's frustration with paperwork because I am going through the same. Now waiting for TWO weeks for inspection of the Engine mount. After various e-mails and phone calls now realised that the the Gentleman in question is in the USA!!!!!!

Now we wait and wait...

Sterkte ou maat....... raak maar solank gewoond aan WAG......................

Went to visit the Trevor and the Thunderbird this morning and got some detailed pictures (Prentjies for the others). I am very exited and can't wait. Trevor cannot do the final assembly/welding before been inspected by CAA inspector, so now we wait.
The performance and handling of this Thunderbird is just going to be in a different class. The engine is way back and well within the C of G. The thrustline is 100% inline with the wings, not like previous 912 Thunderbirds where the thrustline was way, way above the wings and the engine had to be tilted to compensate for this. There is also no mods to the Standard MKII airframe so this will be a quick conversion for future Thunderbird owners.
Trevor has built jigs so that future mounts will be quick to built.

HOPEFULLY not long now.

Hi Johan

Ek het my convertion na ccm op 'n t-bird gedoen met 618 op en soos ek dit het:
Styg op 60mph
Vlieg 60mph
Land 60mph
Het al gevat tot so 75 maar dan voel dit asof die windshield nou gaan waai, en dit was nie gemaklik nie.
Gaan jy al die perde kan gebruik?

Sterkte en groete daar by kroon hulle.

Hi Wolter
Met al die perde gaan ek:
1. My Buurman van 6' 3" en 107kg oplaai. Hou daarvan om 'n pax te hê, om my vlieg met ander te deel.
2. Gaan teen ten minste 800ft/min met hom in, uitklim
3. Gaan teen 70mph cruise teen 12 liter per uur.
4. Gaan in minder as 100m met my buurman in, opstyg.
5. As ek in 'n Rotor beland by die berg het ek baie meer perde om uit te kom.

Ek het al in die 912S TB gevlieg. Hierdie een gaan nog baie beter perform.

Dis wat ek in 'n aerie soek.

Groete daar
