Hi Aerosan,

a Friend off mine fly's a Bushbaby with a Subaru motor, he did a engine mod and had fuel injection installed. I think it develops 115 - 120 hp, a bit nose heavy but fly's beautifully and cruises at 100 mph.

Enjoy and "byt vas", almost finished.

Hmmm, don't forget to mention the engine failed and the plane ended in the bush......

And then there was the Subie in my Savannah.....

But many guys are happy with them in the USA so it is not all bad

Ag jinnetjie tog, daar piepie Rudix nou weer Sanna- hulle goet se betteries skoo pap-sop-nat............

Sorry man!!!

Daar is Subies wat mooi loop, soos ek sê die ouens in die VSA is happy en die plaaslike RAF 2000 Gyros vlieg ook mooi met die Subies, dit hang seker af wie die "conversion" doen...

[Aerosan]

ag nee wat oom Boet dit vat baie meer as dit om ons batteries nat te maak. die masjientjie is mooi gedoen en by all accounts baie betroubaar. Ek het met n paar manne van die USA gesels wat die spesifieke masjien in het en hulle (daar was 5 reports) se almal dat hulle baie gelukkig is. Ek sal maar my eie opinie opmaak.

Manne en onthou nog nooit was iemand veoordeel vir die waarheid praat nie al is dit nie wat die ander oukie wou hoor nie. So Rudix boeta gooi mielies en nommers van manne wat die masjiene in het. Ek sal graag wil hoor waar die betrokke failures was en hoe dit nou gaan.

Jip. Maklik om te se iets is kak. Maar vertel asb vir ons almal PRESIES hoekom dit so is. Dalk red dit iemand se lewe?

[Rudix]

Ja Boet....

Wel, laat ons nou sien....

Ons het een in die Savannah gehad, met 18+ uur se hobbs tyd het die vliegtuig 1.2 uur se vlieg gehad Die res van die tyd was sukkel tyd.... Nie juis baie krag nie, het rof geloop, gesukkel om te start, het meer as een keer 'n opstyg ge "abort" met die einde van die aanloopbaan wat vinnig aankom Het op die ou einde die enjin en ratkas geruil vir 'n Warp drive prop, die was 'n goeie move Het toe 'n 912EX in die Savannah gesit en begin VLIEG Die vlieguig is nou ook omtrent 35kg ligter en balanseer sonder om 'n moerse battery in die stert te sit.

Dan was daar die BB op Rhino met 'n Subie, hy het lekker geloop en het genoeg krag gehad. Alles was lekkek tot hy met 'n bang gestop het (nog lae ure), in die lug, lekker solied gelock, gelukkig was die vliegtuig oor 'n oop stuk en het niemand, behalwe die BB, het seer gekry nie.

Ek het op 'n stadium 'n subie oorweeg vir my Zodiac, nie meer nie....

Gesels me Ebin Mocke van RAF, hulle gebruik die groter Subies in die RAF 2000 gyros met groot sukses.

Oh ja, voor ek vergget... Daar was die afgelope tyd 2 voorvalle van die groter subies wat sommer net skielik gestop het agv 'n elektriese probleem, een plug wat die groot stilte veroorsaak

Ek sê maar net

[JvTonder]

Die Subie waarna Rudix verwys op RhinoPark se olie pomp het opgepak, die eienaar sê hulle kon nie agterkom wat dit veroorsaak het nie maar hy vlieg nou weer lekker met nog 'n Subie in.

Kon hom nog nie in die hande kry om te hoor of ek sy nommer kan uitgee nie maar sal aanhou probreer en vir jou 'n PM stuur.

Het sy nr vir jou gePM.

[Aerosan]

Dankie manne!!

Het die nommer gekry dankie

Baie kere is dit nie die produk wat foutief is nie, dis die vingers wat daaraan vroetel wat al die moeilikheid veroorsaak. Oliepompe breek nie sommer nie, en ek weet wat die storie agter die storie van die plug wat uitgeval het was. Alles vingertjies wat kak aangejaag het. Menslik.

I have an interesting story to share while we are on the topic

This past week-end I visited an old friend who I haven’t seen for years. His father in law rebuilds aircraft engines and his partner classic aircraft (tube and fabric) anyway, the conversation went to "what do you fly" and we ended up speaking about engines. Rotax in specific and this guy pipes up “did you hear that they are removing all Rotax engines from the market" "No why?" He replied, “well the things are so unreliable, breaking down ALL the time" well I questioned him as to what seems to be the problematic thing on the said manufacturer’s engines. He said something like "oh nothing specific". The very next sentence I asked about all of the engines in the workshop in various stages of rebuild. I said but surely in one workshop here I see more Continental, Lycoming etc. engines with conrods through the block seized pistons broken valves and much more to mention. I swear there was more "real airplane engines" in that one workshop that we have commented on in total on our forum

I just smiled and walked away.
Point is ALL things mechanical can and will fail for various reasons. If you make use of a machine, such as an engine, in a application that it wasn’t entirely designed for, such as a automotive engine in an aircraft, you have to accept that certain parts and or devices directly related to the operation of such a machine will need some serious rethinking
So it always takes one special person, like Oom Jan BMW, to make that first step. I’m sure that he will tell anyone that one of the most important steps in this long and tedious process is carefull documentation of each and every experiment that you carry out. I’m very sure that in any one of this documents you will never find a comment like “the thing is unreliable for no specific reason". That will be a waste of paper and time.

So, in my opinion, you can take any machine that you wish, redesign modify and adapt and if you have done half decent job you will be left with a piece of engineering that will serve you well. But hear this if you do this and that because your uncle’s, sisters husband’s brothers boss did this with his and it did or didn’t work, you meneer, are bound to become a statistic.

This is a long story because the next “real pilot” who flies a rented C172, on occasion, tells me that “the dangerous things we risk our life’s with” makes us cowboys, and even more so because we dare to make use of something that isn’t certified, is seriously begging to get bliksemd. If you are going to be too clever for yourself, come into my hanger, tell me about air flow and pressure, please please sir at least understand what you are saying. You are just showing the rest of us precisely how dof you are.

OK now that Im feeling much better, and have aired my views Ill attach a pic or two.

Thanx for being a great bunch of guys

Oh yes, guys the rant is not because of the comments about the engine I appreciate those

Dis waar!

Daar is BAIE ouens wat ook probleme met Rotax and ander "vliegtuig" enjins het, en dan is daar ouens wat selde of nooit probleme het nie....

Sanna, daai BosBaba lyk sommer baie mooi, weet hy gaan lekker vlieg, jy sal hom vir ons op Rhino Park moet kom wys

van die waarste woorde wat ek nog gelees het. Ek dink partykeer daai manne met die rented 7-10k ure een skewe twee`s moet die cowboy badges dra. Sterkte met die BB, dit lyk goed, jy bekyk die hele besigheid van die regte kant af.

Daai neus gaan vra vir n mooi spinner.

Well said, everyone always has more k@k to say than good. Do it right and it will work

The Machine is looking Baie Mooi.
Hope to be joining you soon.
