old man emu Posted October 3, 2018 Share Posted October 3, 2018 I think that there are more videos of Cri-Cri's than there are Cri-Cri's built. 1 3 Link to comment Share on other sites More sharing options...
Thruster88 Posted October 3, 2018 Share Posted October 3, 2018 It's a good configuration to keep an eye on the toy jets to make sure they are not setting fire to the aircraft. Link to comment Share on other sites More sharing options...
Litespeed Posted October 3, 2018 Share Posted October 3, 2018 They are not toy jets...………………………………………..they are for roasting marshmallows. That's why the canopy opens from a rear hinge, so you can reach. Link to comment Share on other sites More sharing options...
old man emu Posted October 4, 2018 Share Posted October 4, 2018 Most of the video clips of this aircraft's flight are followed by inane comments relating to the engines, their heat output, and the effects of insect ingestion. What a lots of ignorant put downs! I see this as an example of experimental aviation at its best. The prototype flew with two 2-Stroke engines driving propellers, and most made since are prop-driven. The 2-stroke engines weigh about 17 kg each. The turbojets weigh 4.37 kg each. The ICE powered aircraft cruise around 90 - 100 kts. During the videoed flight the pilot claims a top speed of around 140 kts, so the cruise could easily be 120 kts. The fuel burn ranges from 4.25 oz/min to 22 oz/min at full power. Let's say that fuel burn is about 15 fl.oz/min in cruise. That's 0.44 litres per minute, or 26.4 litres/hr.

Can Any of you Sandgropers identify the airfield the video was recorded at? Link to comment Share on other sites More sharing options...
onetrack Posted October 4, 2018 Share Posted October 4, 2018 Maybe they deleted that section from the final footage uploaded - but I never saw a pre-takeoff checklist being used - and I never saw any flight controls check being carried out. However, I did see an awful lot of fiddling with the engines startup procedures, and an awful lot of awkward cross-handed switch and controls operation. Seems to me the cockpit layout needs improvement. Link to comment Share on other sites More sharing options...
onetrack Posted October 4, 2018 Share Posted October 4, 2018 OME - I'd have to say that's Serpentine Airfield. Link to comment Share on other sites More sharing options...
old man emu Posted October 4, 2018 Share Posted October 4, 2018 From Google Maps, I'd reckon you are right. Looks like there are some nice unusual aircraft based there. Link to comment Share on other sites More sharing options...
rgmwa Posted October 4, 2018 Share Posted October 4, 2018 Correct. The jet powered Cri Cri is based at Serpentine. There are around 130 aircraft on the field - from memory around 80 experimentals, 20 or so vintage/warbirds and the rest are commercially built. Interesting aircraft include several Tiger Moths and Austers, a Fox Moth, Sopwith Pup, Bucker Jungman, Stearman, Pitts S12, a couple of Tailwinds, Yaks, Culp Special, Stinson, Spitfire replicas, the Silver Centenary, Pietenpol, plus plenty of Jabirus, Zeniths, about 23 RV's of various types and well as Cessnas, Pipers etc. 2 Link to comment Share on other sites More sharing options...
old man emu Posted October 4, 2018 Share Posted October 4, 2018 Serpentine is obviously an airfield where the owner likes to milk the cows in other paddocks. Link to comment Share on other sites More sharing options...

facthunter Posted October 5, 2018 Share Posted October 5, 2018 Various versions since 1973. limited aerobatic capable. I've seen one with the single cyl two stroke engines in the flesh (so to speak). It's very small 16 ft wingspan. Nev Link to comment Share on other sites More sharing options...

I believe he was knocked around a bit but recovered. Didn't know him personally and have no idea where he is now. Link to comment Share on other sites More sharing options...

rgmwa Posted October 7, 2018 Share Posted October 7, 2018 Serpentine's annual fly-in is on next Sunday 14th Oct if anyone wants to come down. Apart from the aircraft, various car and motorcycle clubs, miniature steam engines and other exhibits usually turn up and it makes for a good day out.
