Building the new Bushbaby SAFARI

[Oupa-G]

Just for the Lycoming boffins watch this space when the Bosvark is finished the Lycoming is going to be the next engine on the block that will receive the full Eboxi mods with proper fuel injection and redundancy. A friend of mine had a recent Lycoming engine out in Gauteng he did a beautiful force landing out of the books but with a dual Eboxi system he would have flicked a switch and flown to a nearest suitable airfield. Just some thoughts for the new year.

Eissh Oupa-G, wont you reconsider and rather start with a Jabiru convertion?? There is a great need to get rid of those Bings and I promise you long lines of customers......

[Oupa-G]

The Jabiru is easy to do because it has a very good ignition system so the fuel must be done and that is reasonably easy. But I first want to finish the Bosvark.

We have fuel injected a 912S you won't believe how this has changed the engine . The Bing's are reasonably archaic.

Hi
What about the consumption ?

[Oupa-G]

We fly these engines on the Trike's we are 4 trikes with the same configuration .Two have BMW engines on one is the first conversion the experimental one it is the 1100 S engine and then the 1200GS when we do a fast cruise all in loose formation the BMW do 12.5 liters/hour. The fuel injected 912S does 12.5 lit/hr and the Bing carb 912S does 15 liters/hr. Finally a well tuned fuel injected engine burns about 235grams of fuel per KW per hour so the fuel consumption will be directly related to the amount of power your airframe needs to fly succesfully. The best you can do is not waste fuel . You have a better chance not wasting fuel with injection then with a carburettor. You can only really get one optimum situation with a carb.
Enough said

Back from holiday with a few days to spare so over the weekend the fotos will flow got both props for Safari #141 and #142 for the serial # boffins my Safari "Bosvark" is serial#142 because My DTA trike is also #142 but #142 should be finished before #141 Just some useless information.

Andy Capp the Vansin is a one off in the whole wide world it was built by Carel van Aswegen in Plettenberg bay. First flew in 1978 . The original aircraft was bought by myself from Carel I saw the aircraft being built from scratch and always said if he stops flying I will buy the aircraft. I have done a lot of refinement on the original aeroplane this included moving the CoG forward by making the engine mount longer. I you see early foto's of the Vansin you can see the shorter nose.........

Thanks for the info oupa G! (sorry for the late reply - bit busy having a holiday!! so surfing the net is not top of my priority list. Unfortunately I leave for the big smoke from Cape St Francis tomorrow. ) I really think the Vansin is an awesome looking errie with performance to match!

Good luck with the project for this new year! As an engineer it is clear to me that you guys are leaving nothing to chance and that your modifications and adaptation of the BMW engine has been carefully though through and engineered. It does not stop there though you are backing it up with full and thourough scientific testing. I cant help to look at the GS bikes with new eyes now. Cant wait to hear how it flies!!

Here some of the promised photo's at the moment working out the details of the cooling this could only be done after I got the beautiful prop as the back plate of the spinner dominates the position of the cowling. Also note the ground clearance with the tail l;ifted. Ground clearance should also mean grass, ditch and those lovely little twisters that form below a prop when the prop turns on a gravel surface.

Happy viewing
Cheers Oupa-G

We have been VERY busy today. For the morning we built a set of wings AND finished up the cooling baffeling of the BMW engine. I can for the life of me, not EVER see this engine overheat. every bit of the wind blocked on top of the engine just HAS to go thru the cylinders and cool things down!

[Boet]

All the side top and bottom front baffle plates has been left oversize, so it can be trimmed down later to suit application. Incase you wondered about the "boxy" apearance.

Oupa-G & boet this is looking VERY good. The workmanship is outstanding.

Oupa-G I was out at Grootfontein last Friday afternoon to look at tJonathan's XL in your hangar. I just received plans for mine & will scratchbuild. Shawn showed me the trikes with the BMW motors on as I havent yet decided which motor to use. My build will go rather slow so no rush. Have to say that what you do with the BMW motors have all my interest. Looks like the kind of setup that will work very well in a 60lXL.
