Diesel Fan Sycamore tried the soob engines. They now back to Rotax. Weight is the problem You should rephrase that : It is not the weight of the Subaru the problem, but the weight of the airframe. Designers (as opposed to clients) love the Rotax because of its weight to power ratio. They simply pas...

Eben, you are still not answering his question. He wants to know what are the pros and cons of the HS and then he will make a decision if it is worth having it. Your previous answer does not explain that.

It looks like the Aeroclub and other parties that are defending our case have been overwhelmed by querries on this subject. The message is clear. They are looking into it and get a definate "interpretation" of Part 24 as everyone seems to understand it differently. They will come back to us in due t...

Hi Gertcoetzee, In fact I did transport a RAF on that trailer. Obviously the wheel blocks did not match but that is to be adjusted when you build the trailer. Also the RAF is tail heavy without any pax. As you want the rotor blades parallel to the road for airflow reasons, I would force it on its no...

Hi Rotor-Blade, I don't know who you are but to answer your question, the Xenon is building steadily. A lot of minor frustrations in the way the kit is prepared by the supplier. It also helps to speak the language ! I understand now why the Xenon is not available in kit form anymore. I simply accept...

Yes, I did. I have done many trips like twice JHB-Upington and back, 4 times JHB-Hazyview, can drive up to 130 km/h with the blades on. Some trailers came with a sort of support for the blades but this design is wrong as it is a knife edge that can crack your blades. Also the 2 supports have no pitc...

LearJet on the word "Balance" - I accept your argument. I did not expressed myself correctly. T-bird, I think that your findings have been also witnessed by some RAF owners here. Please note that I have never mentioned any speed. If the RAF is "stable" up to 70 mph, well why wanting to push it above...

I have very limited experience with the RAF to simply have a conversion on it and few more hours solo. I have 500 hrs on the Magni. Regarding the stability issue, I can definitely say that the RAF does not need a HS to fly properly. It is quite well balanced to fly without a tail. Very much like a t...

Hi Spindoctor, The Subaru engine is under-estimated. It runs very smoothly on the RAF and has by far less vibrations than the 914. There is unfortunately a culture in SA that an automotive engine cannot run in a aircraft, and the more you pay the better it must be. Well it is just a matter of going ...
