Hallo,Jaco!Bel my!Of stuur my jou nommer!Groete Johan!

At last we are ready to move to the airfield.
the paper war has started and now we wait patiently.

[JACO]

CONGRATS! LOOKS AWESOME!!!!!!!!!!!!!!

[diesel dog]

At the airfield done some taxi test and very happy with the results.

[Oupa-G]

What a lovely achievement. I do know what it takes.

Congratulations this is what it is all about. Speedy test flying. At least you do not have to prove the airframe.


Cheers Oupa-G

Well done. I am also watching this with keen interest. Please keep us informed with facts and figures. If you do not have it, get the testflying manual on the CAA website under NTCA and use it. It has very good info in it. Good luck

Hi There.
What is the best static thrust you have achieved to this stage.

Beautiful project

[Boet]

Static thrust means bugger all. Static refs is what will make things happen. Gerald, she looks stunning. I can not wait to fly an aircraft with a Toyota engine. A dream come true!! You/ We have done a nice job. See ya next week!

Boet, verduidelik asseblief ?
Ek dink daar is baie van ons wanabee armgatte wat nie die verhouding van static thrust en static revs verstaan nie, beteken 'n goeie static rev nie net dat jy die regte ratverhouding en prop het nie ? I.E. rendement.

[Boet]

Vra vir oom Piet Propeller om dit vir jou te verduidelik. As jou prop se pitch te fyn is sal hy hope static thrust gee, maar jy sal net VINNIG in die lug kom en daarna amper nie genoeg thrust he om jou daar te hou nie. MAW, jou enjin sal uit refs uit loop. N Growwer pitch, daarenteen, sal jou minder STATIC thrust gee, en jy sal nie so vinnig in die lug kom nie, maar jy sal goed klim goed cruise ens. MAW, as die propeller/ pich/ enjin/ ratkas verhouding reg is, sal jy n goeie kompromie performance uit jou fixed pitch prop kry. Ek wens niemand wil ooit weer praat van "static thrust" nie. Dit beteken NIKS.

Hoor hoor Boet!

As ek ouens sien by die vliegveld wat 'n skaal aan die stert vasmaak en dan die spog oor hoe hard die engin trek wil ek weg hardloop

Dis soos om the spog hoe goed jou 4x4 in eerste rat low range trek, maar ry hom so op die oop pad dan gaan jy nie vêr kom nie

[KFA]

Static thrust only means something when you have two different makes of props and you set the static rpm the same and you then measure the static thrust of each prop. This figure will give you the effiency difference between the two. In theory 2 props at the same rpm and same pitch should deliver the same thust but they differ because of prop design and that should give you a apples with apples comparison.

[Boet]

Static thrust ofte nie, hierdie errie se vlieg is nou so naby soos demmit aan n vloekwoord!!

We (the Kalahari/Westcoast trike gang) were privilaged to see this aircraft 'in the flesh' at the airfield and to witness some of the taxi tests on Thursday afternoon. It looks and sounds awesome. The original muffler has been removed for for C of G adjustment, but without it the aircraft seems to perform fine. It just wants to fly now!!

Apologies for disrupting the process so that repairs could be carried out on the trike I was flying after a botched landing (see incident thread). Thanks Johan for the help, and sorry about taking you away from this ground-breaking project.

Reg no done. ZU-FIZ
Proving authority submitted apparently caa are on strike
The Spanish have just landed at home and SA is back to normal, strike action and xenophobic violence.
We have done 6.5hrs ground runs and taxi tests and are ready for test flight once the paper work is in place.
