  1. The reason the Piper Sport, Sport Cruiser, Roko and Bristell look similar is because they were all designed by the same person - Milan Bristell. In an earlier job he was to some extent also involved in the design of the EuroStar/SportStar/Harmony but this aircraft has a distinctly different fin, rudder and tail plane configuration - and has been fully spin tested for EASA Certification.
  2. Actually a Bristell, not a Foxbat. Hope they both get out OK.
  3. Thank you to everyone for your responses. In the main, mostly confirm my own thoughts and those of plastic sheet suppliers.
  4. The screen in the photo is a brand new polycarbonate sheet (with less than 5 hours flying time), installed as a replacement for the original screen. The factory used to fit polycarbonate as standard, but now also fits PET screens, which are more pliable but are a little more prone to scratching. The owner says that no fuel or other chemicals were spilt or used on the windscreen.
  5. I recently noticed this damage to a polycarbonate windscreen. Definitely not stones - the screen remains smooth to the touch inside and out. Questions: (a) anyone any ideas as to what's causing this? (b) Is it dangerous - ie might the windscreen break in flight? © How to prevent in future? All helpful comments gratefully received!
  6. Foxbat Australia Pty Ltd are authorised Matco suppliers in Australia and we hold stocks of certain items used in Foxbat aircraft. However, many common items are available through Aircraft Spruce and all items via Matco themselves.
  7. In our experience, the 912iS is definitely more economical over a steady long-range cruise. But not much different to the 912ULS in shorter (eg under 60-90 minutes) flights, and certainly not for circuits and bumps
  8. Hi APenNameAndThatA To help you out - the Aeroprakt factory no longer offers fuel injection as an option. If you don't like the manually operated hot air system for the carburettor engine (which, by the way, allows the engine to develop full power through using cooler air from outside the cowling), some Foxbats have been fitted (admittedly quite a while ago) with UK Rotax dealer-supplied 'hot coolant'-fed rings round the carby throats. I believe these can be fitted with a valve to open or, in summer, close the coolant flow through the rings. Because the rings move the carby inlets towards t
  9. Oh dear Neil - no, the incident was caused by incorrect operation of the fuel pump. You can drive down the road at 100 km/h and slam the car into reverse. By your reckoning, the result would be the vehicle manufacturer's responsibility, not the driver's. Inconvenient as you may find the truth - a fuel return line is not mandatory on 912 engines - right up front, the Rotax installation manual makes it clear that it should only be used as 'a general guide' and that the airframe manufacturer has the final say. I know you think GA certified aircraft are irrelevant but many of them do not have
  10. When something potentially life-threatening happens, it's very scary, particularly in an aeroplane. Soon enough, those who experienced the event start looking for causes and those around them understandably want to support them. However, occasionally, comments can get blown into huge issues - sometimes based on a misunderstanding or an unintentional error. First of all, the Foxbat did not have a 'fuel pump fire'. The solid-state Facet fuel pump fitted to the aircraft depends on a good fuel flow through it for cooling - hence the instruction to use the pump only for start up or in the event o
  11. The first page of the current Rotax 912 series engine installation manual: "This Installation Manual for ROTAX® aircraft engines should only be used as a general guide for the installation of ROTAX® engines into airframes. It does not represent an instruction for the installation of a ROTAX® aircraft engine in a specific type of airframe or airplane. BRP-Powertrain GmbH & Co KG does not assume any warranty or liability in this context. This Installation Manual shall in no event be used without fully complying with the specific instructions and/or requirements of the manufacturer of an
  12. I think that a few facts have become chinese whispers here. When the owners picked up the aircraft, there was one small crack about 5mm long from a rivet in the bottom right corner of the windshield - which I photographed at the time. The windscreen failure was nowhere near and completely unrelated to this crack. No-one ever requested a warranty replacement windscreen. I offered cover the cost if the owners wanted to replace it locally. I am unaware of any contact from the owners advising me they had or would replace the screen. PS - I was only made aware of other windscreen cracks after the
  13. First, I have great empathy with the pilots and passengers who experience door, canopy and windscreen failures - I have experienced a bubble canopy coming open in flight myself; it was not a pleasant experience. In comparison, losing a piece of windshield must have been extremely frightening. Thankfully, such experiences are extremely rare. A few facts about the above references to the Foxbat may be helpful. 1. There have been no reported cases of 'vapour lock' in the 1000+ worldwide fleet of Foxbats - except for one aircraft in SE Queensland. This is because the wing tanks provide a cont
