Yenn Posted July 2, 2018 Share Posted July 2, 2018 A friend of mine has bought a hangar, complete with aeroplane. He doesn't want the aeroplane. Borabee, Reg 19-3756 Two seat tandem, high wing, taildragger.540kg MTOW, 243kg empty Last flown June 2018 Engine Jab 2200 TTIS 150 hrs engine and airframe Prop wooden 2 blade Radio Icom A-22E Cruise 80kts for 4.5 hrs, 21 l/hr at 2800rpm Mac climb 800fpm. Fuel 100 lites 90 usable contact [email protected] Best offer over $5000 by beginning of August. Hangared and available for inspection at Rodds Bay airstrip. At 5 grand I am tempted just for the Jab motor, but I really don't need another aeroplane or motor. 3 Link to comment Share on other sites More sharing options...
facthunter Posted July 2, 2018 Share Posted July 2, 2018 Used to be a few of them flying. Don't know how you cool a pusher Jabiru. engine. Perhaps it can be done. Nev. Link to comment Share on other sites More sharing options...

old man emu Posted July 2, 2018 Share Posted July 2, 2018 Don't know how you cool a pusher Jabiru. engine. Perhaps it can be done. Nev. Wouldn't the mere fact that the engine is constantly moving through "fresh" air, bum first, provide the same amount of cooling as if it was going head first? The engine area is not cowled. Also, wouldn't the operation of the propeller result in air movement? After all, in a tractor set-up, you can get stone chips on the leading edges of the prop due to debris being drawn up from the ground. Link to comment Share on other sites More sharing options...
fly_tornado Posted July 2, 2018 Share Posted July 2, 2018 don't know how applicable it is to the Borabee 1 Link to comment Share on other sites More sharing options...
facthunter Posted July 2, 2018 Share Posted July 2, 2018 Most pusher installations have more cooling problems than tractor ones. Jabiru have not encouraged it, though they do list it in their installation possibilities. The prop wash is above the plane's velocity BEHIND the prop. The air behind a wing or POD is not clear air and at High AoA's could be anywhere.. Debris is/ can be pulled up from the ground in jets and props in front of the prop or fan at high power/ low forward speeds.. A cyclonic mini twister often forms. I can't see this being replicated in a pusher installation, where there's no clear air for it to form.in. Nev 1 Link to comment Share on other sites More sharing options...

skippydiesel Posted July 2, 2018 Share Posted July 2, 2018 What a little beauty. At that price, if Jab proves unreliable, fitting a Rotax 912 would be the next step. Link to comment Share on other sites More sharing options...
winsor68 Posted July 2, 2018 Share Posted July 2, 2018 You gotta keep the air around long enough for the motor to cool it in an air cooled motor... 1 Link to comment Share on other sites More sharing options...
facthunter Posted July 2, 2018 Share Posted July 2, 2018 The Jabiru engine is lightweight, but direct drive, small prop, aircooled. . A 582 is good in the " lightest for power delivered" Power/ weight stakes and liquid cooled. It's the only Rotax 2 stroke still produced for aircraft.. The 912 and 582 have to have a radiator "somewhere". Hard to be neat sometimes. Nev Link to comment Share on other sites More sharing options...
Yenn Posted July 3, 2018 Author Share Posted July 3, 2018 This one seems to run cool in our Qld heat. The owner builder made cowls, similar to the Jab ones, but back to front. It runs well, but the owner builder is giving up flying, has let hid BFR expire and it is awkward to renew it. 1 Link to comment Share on other sites More sharing options...

Yenn Posted July 4, 2018 Author Share Posted July 4, 2018 How did I merit a demerit point? Now that it is restored is that a plus or a minus for me? I am now as confused as I was when I first came across default in computer terminology. It was not what I understood from my army days. 1 Link to comment Share on other sites More sharing options...
facthunter Posted July 4, 2018 Share Posted July 4, 2018 You know pilots aren't allowed mistakes. So.... You "merit" (earn) a demerit for making a mistake . Since you corrected it "quickly". You have your demerit removed, since pilots are encouraged to make corrections to mistakes, and quickly because it works better that way. This is applying the carrots and sticks in a real world situation. Aren't you just one lucky boy to have such fair and reasonable treatment?

winsor68 Posted July 4, 2018 Share Posted July 4, 2018 So the Borabee is basically a Drifter with a Canopy on steroids. There did used to be quite a few of them around flying 20 years ago.. Does anyone know the history of the aircraft? You hear very little about them. Link to comment Share on other sites More sharing options...
Kyle Communications Posted July 4, 2018 Share Posted July 4, 2018 Rotax 618 on here will know...he designed them 1 Link to comment Share on other sites More sharing options...
facthunter Posted July 4, 2018 Share Posted July 4, 2018 There would be four or so at Natfly say 15 years ago (it could be more).. They are sort of a lighter version of a Drifter or Thruster. Both of which are OK for school work. and can take a bit of knocking around. The bee is more of a lightweight homebuilt you use on calm days. People DID fly these things long distances but not generally across Australia like you can with a Jab 230. I could be wrong, but that's how I see it.

Yenn Posted July 5, 2018 Author Share Posted July 5, 2018 Yhe one which is for sale and another were built at Rods bay and another was nearly completed there also. All 3 have flown as far as i know. The other one completed at Rods bay was involved in an incident with a whirlie and the tail boom was damaged. Fixed, by sleeving a second tube inside the boom to reinforce it. 1 Link to comment Share on other sites More sharing options...
Frankus1aust Posted July 7, 2018 Share Posted July 7, 2018 A digital engine monitor would be a good start for experimenting with cooling 1 Link to comment Share on other sites More sharing options...
