Johan,
Thanks vir die 'prentjies. Skuus ek kon nie Saterdag saamvlie nie.
Ek kan nie wag om die eindproduk te sien sien.
Groete
Deon

Definitely agree. Some other manufacturers has abused their market share. The time has come.
See my post under "Aircraft parts and accessories", to assist interested parties.
We must just stand together and make this happen.
Wait till my yellow 110HP machine takes flight...

I am fitting a GSC Ground adjustable 68". I like and prefer the P-Prop but I wanted to have an adjustable prop to play around with the pitch a little bit.
More details on GSC at: http://www.ultralightprops.com/tech_ser ... adjust.htm
Would love to meet when at Xwinds
Regards

Jy is reg, dis net wat die Thunderbird soek. Meer perde.
Jong, ons wag vir ons vriende van CAA om finale inspeksie te kom doen. Hopelik maak hulle die week 'n draai.
Sal julle op hoogte hou.

Hi AH
Was at Xwinds last Saturday and Trev showed me the engine mount and other stuff, must say I cant wait to see the final product! Everyone now still waiting for CAA to get their backsides into gear...I think Trevor is just as excited and anxious to get your bird into the air

But when something "illegal" is done, they are quick to be on your case, maybe they must ask themselves why people bypass them where possible! Corrupt like the rest of goverment. Wish there were a bigger international autority where we can report their non existant service.

Good News
The Thunderbird with the BMW R1200 engine will be on display at the Kroon Fly in on the 28th of May. It is not in flying condition yet, still some work to do but you will be able to see what the conversion look like.
