Grasshopper Posted September 24, 2008 Share Posted September 24, 2008 Has anyone out there fitted a Vortex canopy to their Fling Wing? Just carved out my one and no way does it fit. Off out tomorrow to buy a bit of florists brown foam to carve out my one one.Any hints on where I went wrong Nigel (Hawes)? Quote Link to comment Share on other sites More sharing options...
Ben Mullins Posted September 24, 2008 Share Posted September 24, 2008 Hey all, Having fun on this build, its my first. I just wondered would it be possible to use film from a camera as a hinge? Its just I dont want to have a trip out for just hinges! Quote Link to comment Share on other sites More sharing options...
Rob Irwin Posted September 27, 2008 Share Posted September 27, 2008 Hi Grasshopper,I bought a canopy from Vortex-vacforms and thought the same as you. I decided to make a paper mache copy of the canopy and used this as my first attempt. Once you have cut the shape, you need to squeeze the ends together as shown below. I also had to add a bit of balsa on the top of the nose as the curve on the canopy didn't fit. Not to sure if this was my cutting or the canopy shape........ Hopefully the pictures below give you a guide.Cheers, Rob. Quote Link to comment Share on other sites More sharing options...
Grasshopper Posted September 27, 2008 Share Posted September 27, 2008 Rob,thanks for the feedback and the exc. pics. Yes, it was the width which threw me. I had 2 delivered (don't ask why!) so cut one roughly to try to fit it and found it was just much too wide. Knowing that you have made yours fit - and well, I will try with the other one. If that fails then its a Depron carving job I guess. I have added carbon strips to the fin and wing as I feel certain this will be one to ding, hopefully not on its first flight. I broke the fuselage near the tail on my Easy Glider pro - 3 times - before I got the hang of that and I now have a couple of carbon strips down the length of the fuselage to hold it all together Thanks again, Grasshopper Quote Link to comment Share on other sites More sharing options...
Grasshopper Posted October 15, 2008 Share Posted October 15, 2008 Oops, this one stings! Maiden flight, still day, no one around, underhand launch on full power and ZAP, instant corkscrew left and into the hay. In the air about 2 seconds I would say.Nothing broken apart from the prop thanks to CF strips on the wings and rudder. Now waiting for 4 new props at the local model shop out here in Brittany. Next time I plan to reduce the control throws although saying that I did not even have the time to get my hands on the sticks before it went in.Watch this space.

Ken Cutty Posted October 16, 2008 Share Posted October 16, 2008 Hi Nigel, Ive built my Fling and flown it 7 times but never managed to land it yet! it glitched and crashed; I fitted a better receiver and then I've spun and crashed it when trying to fly too slowly.Its a tough little thing, so far I've only managed to break props (6of) thanks to the long grass around our club field. The Fling certainly generates a lot of interest and my instructor Graham is going to build one also.,in the meantime I shall strive to complete a flight, I should add that I am an RC pilot of 13 months on the wrong side of 60 ,not as quick possibly as I need to be, but I'm enjoying the challenge.

clive peterson Posted October 20, 2008 Share Posted October 20, 2008 Well I have made one to, I just weighed it and its 285 grams less the lipo, is this about the correct weight ? I have used the recommended motor and it got a 6.3 x 4 prop, I am going to use a 3 cell 800 mah lipo, just playing with it and its pulling down a lot I am a bit doughtful, anyway its worth a try, just need a good day for it now, I must say it looks different , I have made a shorter canopy out of built up balsa scooped out on the inside I don't think this will make a difference.

clive peterson Posted November 2, 2008 Share Posted November 2, 2008 Well Just to let you all know its now flown, Quite a windy day its great really fast, penetrates the wind well to its a bit sensitive on the up on the elevons, I have now put in some expo and it fly's great, loops and rolls with no problem, I am impressed.

Rob Irwin Posted November 18, 2008 Share Posted November 18, 2008 Hi All,Below are some pictures of my Fling wing. I'm a slow builder but it's now ready to go! I just need to wait for the wind to die down.................... Quote Link to comment Share on other sites More sharing options...

Ian Regan Posted November 23, 2008 Share Posted November 23, 2008 NICE AND EASY TO BUILD BUT AFTER 3 TIMES TRYING TO FLY MINES IN THE SHED WITH A BROKEN TAIL will get around to fixing on day and try again, needs to go at speed but it came back down a speed henc its in dock for now, Quote Link to comment Share on other sites More sharing options...
Peter Goebels Posted November 28, 2008 Share Posted November 28, 2008 After a considerable break from flying, I recently dug out my surviving glider (30+ years old and still ok) I happened to pick up the November issue of RCM&E and read the 2nd part of the fling-wing review. Trying to get hold of the 1st part seems a bit of a problem but hey presto I found this forum section. Glad I did as it really enforced my plans to have a go at it. I'll keep you guys posted re the progress Quote Link to comment Share on other sites More sharing options...
Grasshopper Posted November 28, 2008 Share Posted November 28, 2008 Hi Peter, I had the same thoughts after a break of 20 years or so from Middle Phase etc. I now recently have bought an Easy Glider Pro which is excellent in almost every way and copes well with the interminable Brittany breeze!The Fling was a different matter as you will see from my post above. I wish you luck !! Quote Link to comment Share on other sites More sharing options...
Rob Irwin Posted December 7, 2008 Share Posted December 7, 2008 As today was still, I took the fling wing out for its maiden flight. Thank goodness for heather! The plane had the following running gear; Motor Max CF2812, battery 2S 860mAh, a 9 x 3.5 prop and weighs around 300g. Elevator travel +8mm -5mm, Ailerons travel +10mm -5mm.Conditions were wind free over a gentle heather covered common area. The first attempt in lauching ended with a violent flick to inverted and landing in the heather. I decided to reduce the throttle on the next lauch and dial in a bit of trim to counteract the roll. On the fifth attempt she took to the air! She looks great Nigel!To my astonishment/surprise I forgot to open the throttle to full as she followed the profile of the slope to the bottom. Just in time, opening the throttle resulted in a climb out and suficient height was gained to explore the performance.She flies with a reasonable turn of speed. The ailerons were fine. I could turn and roll sharply. The elevator seemed curiosly ineffective, so much so that I found that height (up and down) was mainly adjusted with the throttle! Attempted loops turned into stall turns/wing overs.Landing was a case of reducing height over the heather until she flicked in a low speed. (I think my speed was too low) Unfortunately, I only have one battery so only one flight to report on. If I can sort out the elevator I think she will be fine.If Nigel Hawes is reading this, maybe you could be so kind as to give me your thoughts? I have a gap of about 3mm between the elevons and wings. I used hinges with pins (see photo below). Should I tape this up? Could this be causing the inactive elevator? Also do you think a 9 x 3.5 prop is too large? I guess the excessive torque at the launch causes my probelms. Finally how critical is the balance point. I may be slightly nose heavy. Cheers,Rob.

FLY ELECTRIC Posted December 9, 2008 Share Posted December 9, 2008 Hi Rob,Fortunately Steve hargreaves directed me to the thread so I could reply - its been too busy to follow since the arrival of my baby son four weeks ago!The balance point on this model is EXTREMELY critical; 3mm can be the difference between excellent flight characteristics and an unmanageable model.The elevator problem does sound like C of G but the gap won't help - for the work involved it might be an ifea to tape them up but apply the tape with full down on each side so it doesn't restrict the downwards movement.After criticism that my designs always followed a "safe" formula it's interesting that I release a more challenging design and everyone gets different results! Two of my friends made them, one flies superbly, the other is awful. I think it's all down to build accuracy and set-up whether the Fliing Wing you build flies well or not. Don't worry about the 9" prop, mine uses an 8.5" prop and I simply launch it at half throttle. Nigel Hawes. PS - Top job with the finish, Rob!

Rob Irwin Posted December 9, 2008 Share Posted December 9, 2008 Hi Nigel,Thanks for the reply and congratulations on the new arrival!I re read your artical (October RCM&E) and you do mention problems with the COG too far forward. It was quite strange flying something that had no elavator authority.I'll tape up the gaps and report back when I next go flying. It may be a few weeks or so.Cheers,Rob.

Steve Hargreaves - Moderator Posted December 9, 2008 Share Posted December 9, 2008 Of course what Liam really needs right now is a 1/4 scale Tiger Moth so he can go up for a flight!!!!My Fling Wing nears completion & test fright time approaches.....!!!! Mind you I've made a bit of a hash of fitting the canopy.....why am I always rubbish at that bit!!! Quote Link to comment Share on other sites More sharing options...
Papa Posted December 10, 2008 Share Posted December 10, 2008 Congratulations on the arrival of your son. You have no idea how much your life will change but may be you are getting an inkling by now. I have just completed my Fling wing and showed it off at the club. Lot's of interest and since I am just a trainee it would be too much plane for me at this point but the experienced fast flyers were intrigued and I have no end of volunteers to maiden it when the snow melts. I don't think it would work indoors! We just got three inches of snow but it's melting. If we do some winter flying I may try it on the snow.Jack HigginsToronto.

FLY ELECTRIC Posted December 10, 2008 Share Posted December 10, 2008 Thank you all very much!Liam is actually my 3rd son, but the first with my new wife who is 18 years younger than me, so it's a new experience for Rachel and a very special second chance for myself.Believe me, we are enjoying every day of Liam's life!Definitely one of my better designs!

Rob Irwin Posted February 7, 2009 Share Posted February 7, 2009 Hi Nigel, Below are some flying shots taken from a video camera. She looks good it the air! Quite enjoyable to fly to! However, you need to be careful not to slow her up too much or open the throttle without care. Either seems to send her into a vicious spin and dive. Two out of three times she hit the deck. The first was into heather and the second into the ground. Straight as an arrow she imbedded the prop adapter into the ground. Damage on both occasions was just the prop. The airframe is so light you have to be quite unlucky to break it. I flew it the time it hit the heather but someone else was at the controls when it landed in the ground. On both occasions neither of us could get out of the spin. Any clues on reducing the chances of the spin? Also what's the cheapest props you know of? cheers, Rob.

Aidan Holmes Posted February 15, 2009 Share Posted February 15, 2009 Another Fling Wing flies - in OZ! G'day, just thought I'd check in with a a pic of my Fling Wing. I've just posted a small report on it in RC Groups so I won't retype it all here. I will say that I think this model will prove to be alot of fun to fly. Mine certainly isn't for beginners though, seems to be a bit of a handful. Now I just need to add some extra colour to the bottom to aid with orientation. It certainly is unique and looks different in the air to the traditional 'tailed' models I'm used to. Quirky as she is, I think she's very attractive. A quick note for Nigel and all the RCM&E staff. Thank you so much for the inclusion of plans such as this one. I especially like the fact that this one is designed to be built on a budget. I'm lucky enough to have started in RC building from balsa and I want to continue this way (though I will confess to a couple of foamys). Plans such as this one mean I can keep my RC budget down and have a load of fun doing it. Keep up the good work. I wish we had a magazine in Australia as good as RCM&E, I like to see what products are available locally, however nothing meets the standard of the articles and journalism in RCM&E. I've got my newsagent keeping one behind the counter for me each month. Cheers, Aidan. Quote Link to comment Share on other sites More sharing options...
