Sapphire Posted June 6, 2012 Share Posted June 6, 2012 Has anyone ever flown a single seater Chinook? There is one for sale with a 277 rotax near me. I know all about the engine but the research I have done on the aircraft is disturbing. It has two significant problems. The tail boom has snapped off killing a few pilots. In flight, the frame, especially the tail section, can distort causing no control over pitch. The a/c pitches nose first into the ground. There is a video of that happening. There are a few cases of near misses and fatalities to that. The boom has a modification to strengthen it and the tail section can be brased with wires. This plane is not to be confused with the two seater which is made by a different manufacturer. Norm Link to comment Share on other sites More sharing options...

Sapphire Posted June 6, 2012 Author Share Posted June 6, 2012 With cause and effect so obvious and long term why wouldn't you give this one a miss? It may come off my my wish list. However, there must be someone out there game to still fly it. Perhaps those and other recommended modifications solved the problems. The space shuttle went about the same way. It's called tombstone technology. Every means of transport developed works on that principle Link to comment Share on other sites More sharing options...
Guest ozzie Posted June 6, 2012 Share Posted June 6, 2012 They were very popular in Canada back then. Maybe jump onto the EAA forums and ask about them. Link to comment Share on other sites More sharing options...
Tomo Posted June 6, 2012 Share Posted June 6, 2012 This got the wing warp for banking? Link to comment Share on other sites More sharing options...
Teckair Posted June 6, 2012 Share Posted June 6, 2012 The Chinook is a proven design. I bought one 25 years ago and learnt to fly in it. Mine was 2nd hand and had been around a lot before I got it. Back 30 years ago they were thought to be ahead of their time and there was a few of them around. I still have mine but have not flown it for some years.

Teckair Posted June 6, 2012 Share Posted June 6, 2012 This got the wing warp for banking? No they do not have wing warping, you can't have wing warping with a double surface wing skin and 2 lift struts one on the forward spar and one on the the rear spar. The Wheeler Scout had wing warping which was totally different. Link to comment Share on other sites More sharing options...
Sapphire Posted June 6, 2012 Author Share Posted June 6, 2012 This got the wing warp for banking? The wing warping was given away quickly in its development. This one has flaperons. Stalls at 20 some knots and cruises at 50 kts. and vne is arount 60 to 100kts depending on your source. Burns abut 6 litres per hour which is good for endurance but not getting from A to B. Good low performance motor glider. Link to comment Share on other sites More sharing options...

winsor68 Posted June 6, 2012 Share Posted June 6, 2012 There is a single seater sitting with the wings off in a hanger at Marian... I am guessing the wing warping comments come from the fact that the skins are in one piece but do in fact have separate ailerons... very ingenious design IMO. 1 Link to comment Share on other sites More sharing options...
Teckair Posted June 6, 2012 Share Posted June 6, 2012 Does yours have all the modifications that have come up? Mine has what people who don't know think is wing warping it is the very early model. I know of several mods on mine. A doubler on the fuse tube and reinforced wings at the aileron area. Chinooks never had wing warping. Link to comment Share on other sites More sharing options...

He did specify "low performance" Motor Glider... didn't say exactly how low... probably on par with a Parachutist wing suit... lol Link to comment Share on other sites More sharing options...
Sapphire Posted June 6, 2012 Author Share Posted June 6, 2012 Correct!! Yes, true wing warping would be where one wing changes angle of attack. Link to comment Share on other sites More sharing options...

Try to get fast from one thermal to another and you'll sink like a rock. Flew a ka6 for a while and could out thermal high performance gliders. Push the nose down to 60 kts and your variometer is screaming sink to you/ Link to comment Share on other sites More sharing options...
Peter G Posted June 6, 2012 Share Posted June 6, 2012 I own one that Dad and I have fixed up but not yet flown but I have lots of video and info from other chinook flyers :) we upgraded a few things like changing all the control cable pulley's from the old warn out bushed ones to nice stainless bearinged ones, re wired all the gauges as they were not right when we got it, made a longer pullstart cord and added a pulley above the seat so it can be started while sitting in the seat, felt to dangerous starting it while being behind the wing struts and not being close to the throttle, upgraded the elevator bearings for the main pivot which I found were worn out ( got them from the Canada Chinook factory ), mine has the boom mods done and also the alum pipe between the wing struts has been replaced for steel as these have failed.... They have great cabin room for a single seater too. plus I like the look of them too :) there is a video here of a US bloke enjoying his chinook to give you a idea of how well they fly... http://www.lightsportaircraft.ca/volume1-issue9/webcast-3/ here is a good look at one on youtube too https://www.youtube.com/watch?v=pqlzw-aQMjk from what I found they are only a slow flying plane and only had flight issues when people tried to fly them fast which caused the pitch issues mentioned Specs are : Cruise Speed: 45 .mph Stall Speed: 20 .mph VNE: 65 .mph cheers Pete Link to comment Share on other sites More sharing options...

The Sapphire I used to have was a bit of climb, and the Varieze would turn you into a ballerina. That 60 kt [65mph] sound more realistic vne. Ideal for thermalling as long as it has good aileron contol. They have thermalled these engine off for long periods. The Chinook I was looking at on Gumtree is not there anymore so he may have sold it. Now looking at another Sapphire or even a Rutan designed Quickie.

If your interested there is a chinook for sale in the Sport Pilot mag (Add 2937) all yellow with the new version full span aileron wings and upgraded tail... only has the 277 engine but includes a trailer too.... I would get it my self if it wasn't so far away...... located in WA :) Link to comment Share on other sites More sharing options...

The Sapphire would be more like a motorised glider there is a WA Chinook like you described in the latest RAAus magazine. Link to comment Share on other sites More sharing options...

It's about hour drive from me. There are some Sapphires for sale and coming up for sale. A while back I put an ad out for a Quickie in the local paper; they are a hard aircraft to find. Eventially a lady phoned me up and said I could come anytime to her place for a "Quickie" 1 Link to comment Share on other sites More sharing options...
