Ian F3F Posted February 21 Posted February 21 There have been some fantastic sub 3m models, from the Wizard Compact to the unobtanium Caldera and of course the F3F world record was held by Lin Kuo Ping with the Needle 100 and a time of 24.58. After meeting with Dieter Perlick in the summer and seeing his latest Caldera design, combined with a few drinks with the other members of Team Saker- time to take the plunge- The 2.65m Wyvern test model arrived in December I still love the Saker and I’m not trying to make something better- but different. I’ve always had a love for smaller models and the Wyvern’s design is (I hope) a combination of the aspects of the Saker and 2.5m Falcon that I love the most. The Wyvern also contains a number of aspects of aerodynamic evolution. Setting up a new design is a fantastic way to take on a new challenge. This winter has seen me braving just about the best and worst conditions I could find in order to test my new Project.-. Slope dog definitely preferred the lighter wind days but the Wyvern lapped up all conditions. Although a model’s performance is influenced by many factors other than the wing- this is an area that has seen some changes. Shape and camber details are more difficult to see by the naked eye but when you try to fit a 10mm servo in the aileron it becomes more obvious. A wing thin enough to cut through the air but with enough camber to respond well to snap flap was an ambitious goal. The fuselage retains the ballast tube and sculped sidepods of the Saker. Ballast won’t be an issue but there is now room in the joiner for 600g of additional weight in case you really really want to go heavy. I’m sure there’ll be more updates. 3
wookman Posted February 21 Posted February 21 Having seen the Wyvern on Mickey's in light crossed conditions it certainly looks to have both pace and agillity.
Joe Cubitt Posted February 21 Posted February 21 (edited) JP insisted that I pop up to Whitesheet just before Christmas and along with Ian I watched him slice the air up with this extraordinary little beast. With our JP on the sticks, it looked very locked in and gained pace with every lap. I want one!. The old adage of, if it looks right, it’ll fly right certainly applies here. It has some quirky scallops on the fuz and a well balanced plan form, I like it. It’s certainly a model that will entice me back into competing again. I have to point out, that I’m not connected to the designer/ retailer in any way. other than extended family Edited February 21 by Joe Cubitt
Jep Posted February 22 Posted February 22 (edited) Trying out some small servos, rather over complicated servo frame and linkage. Frames are very well engineered but a big fiddly for my fat fingers JP Edited February 22 by Jep 1
Ian F3F Posted February 22 Author Posted February 22 I knew there was a reason i squeezed in 10mm servos! Looking neat.
Julian Beckett Posted February 22 Posted February 22 Can't beat Tomas Liu's stuff. Beautifully engineered 2
Julian Beckett Posted February 22 Posted February 22 She looks mint Ian. Might have to take a run at one o' them...
Jep Posted February 24 Posted February 24 Well I managed a quick first fly today, very low conditions on the S/W bowl at the Longman. Had a little play with settings but need a bit more air to get these right, but it did feel very easy to fly JP 1
Jep Posted February 28 Posted February 28 Well had a good ish session on Sunday morning befor the rain, have to say this is a very well mannered plane. it feels very quick plus easy handling, aerobics where no problem as was it’s handling with crow. The slope I was using has very smooth sea air so this helped, next an inland site to judge the plane there. So far no real issues, I think Ian has another great glider to add to his list JP 2
Ian F3F Posted March 17 Author Posted March 17 Sorry no pics but fun to fly the Wyvern today at whitesheet. Good fun to see JP and his Wyvern in the same variable air. The Wyvern certainly sniffed the lift out well for me and turned it into fun. Champ of champs next weekend then
Ian F3F Posted April 15 Author Posted April 15 If last week was winter flying in the storms, this week was thermalling on a spring day. Each one with the Wyvern and I've enjoyed every flight. The Wyvern does keep putting a smile on my face. I think that I've started to settle on the model set up. The CG can be moved around a great deal to give different styles of turn but she's has remained well dehaved. Ian 6
Ian F3F Posted May 27 Author Posted May 27 Fantastic to meet up with jp at white****e today. A short notice opportunity for me, both JP and i had both our Sakers and Wyverns. . I wanted to test fly my full production Wyvern. Its come out over 200g lighter than the prototype model i have been flying. Helped by a more aggressive cg the new wyvern was really ripping through the turns in light air. . I split my flying time with my trusty Saker, a great model but the Wyverns have just been giving me so much joy this spring I think almost all my flying has been done with them. shropshire again next weekend, could be looking for a northerly slope with the Wyvern in hand. 3
Jep Posted May 28 Posted May 28 Managed a couple of flights with the Wyvern yesterday, pic of my Bananas Wyvern and Sakers. Was interesting to compare in very varied conditions at WhiteSheet, plus dodging showers made a fun few hours. Wyvern was way happier in the light air, sadly rain stoped my fun and I got bored taking planes apart and together all the time still a good day if a little damp jp 3

Ian F3F Posted October 8 Author Posted October 8 If there is a retailer who would like to stock/sell the Wyvern, please get in touch. Ian
Ian F3F Posted October 20 Author Posted October 20 Just about stopped grinning after yesterday's flying on Whitesheet's NW slope. The last 2 weeks have been testing the new Wyvern tail on the original wings and as a new lay up model. Last week on the Mynd in big air the Wyvern gave more vertical performance than I've had in a long time. Yesterday was far lighter conditions but with the weight savings that the new lay up have given. The Wyvern just grooved and ripped up the slope maintaining it's energy so easily- even my thumbs didn't mess it up too badly! This model just keeps being too much fun- I must fly some other models again soon! Ian 3
Ian F3F Posted November 23 Author Posted November 23 A wet day so I've started retro fitting some CHAservos into the fuselage of a Wyvern. Combined with some horns supplied by Tomas liu it makes even my fit outs look neat! 1
