Sam Wragg Posted September 14, 2014 Share Posted September 14, 2014 After resurrecting Magic and assembling an ARTF Curare I have had an immensely enjoyable season flying Retro at Ukcaa events. Doing this has whetted my appetite in flying F3a again after walking away from the Gbrcaa several years ago feeling jaded plus i felt the current trend of models had outstripped the pockets of the ordinary man,as to build and design your own model to keep within the 5kg rule was nigh on impossible.... Current F3a has become plug & play. This summer with beaming smiles talk between my "Pit Man" (John) and myself switched to what shall we build next to complement our fleet? It didn't take long for us to unanimously decide on Wolfgangs Matts Arrow as it was Magics competitor. So looking forward to doing some proper building for next season I intend to post a stage by stage sequence of "Team Wraggs" efforts. We hope you enjoy Sam & John Quote Link to comment Share on other sites More sharing options...

Martyn K Posted September 15, 2014 Share Posted September 15, 2014 He he.. That's my kind of mistake... Following this one Sam.. Martyn Quote Link to comment Share on other sites More sharing options...
reg shaw Posted September 15, 2014 Share Posted September 15, 2014 While your at the corrections Sam, unless Redshift made a special sidemounted prop driver version, that'll be a side Exhaust Redshift in the pics! Watching with great interest, I had an Arrow with a Redshift when I was ickle, a proper aerobatic model!! Ian. Quote Link to comment Share on other sites More sharing options...
Sam Wragg Posted September 15, 2014 Author Share Posted September 15, 2014 Yes; Rear Ex is at home tucked away this Redshift in in the workshop destined for Curare we've just finished and ready for painting Quote Link to comment Share on other sites More sharing options...

Sam Wragg Posted September 18, 2014 Author Share Posted September 18, 2014 Beginning to take shape now,,,,,Forgotten how enjoyable it is shaping a Fuselage Arrow & Curare side by side (Curare nearly ready for glassing) Next stage is to form the rolled ply pipe enclosure Quote Link to comment Share on other sites More sharing options...
Martyn K Posted September 18, 2014 Share Posted September 18, 2014 Looks great Sam. I agree - Sanding/Caving sheet fus's is great fun. Very therapeutic. I hadn't realised that you were building a Curare as well. Martyn Quote Link to comment Share on other sites More sharing options...
Sam Wragg Posted September 18, 2014 Author Share Posted September 18, 2014 Yes Martyn it will be nice to compare the Artf electric Curare against the Plan built i.c version. Little did i realize in resurrecting Magic it resurrected my enthusiasm for building 'Proper' pattern ships again and the enjoyment in flying them again Sam Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted September 18, 2014 Share Posted September 18, 2014 Lovely woodworking Sam, nothing compares to shaping balsa Cheers Danny Quote Link to comment Share on other sites More sharing options...
Steve Dunning Posted September 18, 2014 Share Posted September 18, 2014 You know where I stand on 'build your own'. There's nothing to compare to the satisfaction of flying a model that you've constructed yourself. Steve Quote Link to comment Share on other sites More sharing options...
Martyn K Posted September 18, 2014 Share Posted September 18, 2014 Absolutely 100% correct... even if your model looks decidedly second hand when its new (like mine), I would rather fly that than anything else. Martyn Quote Link to comment Share on other sites More sharing options...
Sean Tracey Posted September 18, 2014 Share Posted September 18, 2014 Very nice model indeed as opposed to to days models. I myself was lucky to come across a kit of the Kwik Fli MK3 by Graupner in its box complete in very good condition. The first the first time I ever saw this Aircraft I was hooked and I always swore that I would own one someday. This and a Carl Goldberg Skylark are to be my winter builds. I am really looking to building them .I will do a photo or two of the said builds. Sean. Quote Link to comment Share on other sites More sharing options...

Sam Wragg Posted September 21, 2014 Author Share Posted September 21, 2014 We decided to make a 1/64 rolled ply pipe enclosure instead of aluminium as stated on the plan, after the second attempt we managed this, The ply formers will be cut away eventually? after carbon tows are added Decision time now?? After readings the engine nomenclature and deep discussion, as much as we wanted to fit the intended engine i believe the Racing Rear Ex Redshift will generate too much noise as it develops its power around the 18000rpm mark. Until we decide on different power plant building is on hold as the engine / pipe determines the detailing around the pipe enclosure Kettle's on & time to ponder Sam & John Quote Link to comment Share on other sites More sharing options...
Sam Wragg Posted September 29, 2014 Author Share Posted September 29, 2014 Finally decided on the choice of power plant. The decision at this stage of the build is important as i wanted to incorporated soft mount system to keep noise / vibration to a minimum, so with this in mind i opted to use my other OS60 RFP with a view that i can fit one of my Hanno Specials at a later stage (if i wanted). The first step was to manufacture the Beach engine Bearers, this is how i went about the task Beach Engine bearers + Jig made to width of OS crankcase Bearers & jig set out on board prior to marking out Bearers tacked onto board The whole assembly offered up Bearers drilled with M3 captive nuts epoxied in place. The central holes are relieved for the engines M4 set screws Aluminium bearers in situ The completed soft mount system prior to epoxying into position.

Martyn K Posted September 29, 2014 Share Posted September 29, 2014 Are you actually allowed to put a Hanno engine into a Wolfgang Matt design? I thought that would be forbidden Very neat work by the way. Where do these soft mounts come from Sam? Martyn Quote Link to comment Share on other sites More sharing options...
Sam Wragg Posted September 30, 2014 Author Share Posted September 30, 2014 Ha Ha I was contemplating using my Webra 80 R- Ex. but it was too tight a squeeze. The soft mount is my own design made out of 4mm Ally plate with impregnated rubber bonded on. The isolated bolts are just 3mm Cap Heads using 3mm oversized washers again with rubber bonded on, then diesel fuel tubing cut to length and is slid up over the shank of the bolt up to the head making sure its the correct length so that it compresses when the whole assembly is tightened up. The Blue Cap Head washers are from FastLad just to add the finishing touch Sam Edited By Sam Wragg on 30/09/2014 12:34:56 Quote Link to comment Share on other sites More sharing options...
Sam Wragg Posted October 3, 2014 Author Share Posted October 3, 2014 After missing out on a Magic kit this week it gave me the impetus to get stuck into Arrow. Bearers glued in position All i have to do now is in-fill with balsa & sand to shape Quote Link to comment Share on other sites More sharing options...
Sam Wragg Posted October 4, 2014 Author Share Posted October 4, 2014 Finished nose area In-filled with balsa and sanded flush. We can now move onto the pipe enclosure I'm really enjoying this build, its better than assembling ARTF models Sam Quote Link to comment Share on other sites More sharing options...
Sam Wragg Posted October 20, 2014 Author Share Posted October 20, 2014 Final nose bay with soft mount installed Now the engine bay is complete i can move onto the pipe enclosure and pick up where i left it. After some head scratching i ended up with producing this, unfortunately a minimum amount of lightweight filler was used around the front of the enclosure to maintain the shape of the model 3mm carbon peg to locate Light-ply retainers glued in place View from front View from rear. Before i can progress Arrow i now have to move onto the producing the Tail-plane 1 Quote Link to comment Share on other sites More sharing options...
Martyn K Posted October 20, 2014 Share Posted October 20, 2014 That is a lovely looking model - some gorgeous curves as well. I think you should call it Naomi but hopefully it will be better tempered than the other one. What is the tail pipe in this context? Martyn Quote Link to comment Share on other sites More sharing options...
Sam Wragg Posted October 20, 2014 Author Share Posted October 20, 2014 Curvy indeed, It will be nice to see Arrow and Concept side by side next at years meetings. The tailpipe in context is a bike stand put out to pasture by Mrs W . Wolfgang calls to use an 1"dia pipe that exits from the underside.. I have decided that i will use my idea as used on Magic as i find it more user friendly As you can see its just a rectangular box that allows for greater adjustment Sam Edited By Sam Wragg on 20/10/2014 16:47:31 Quote Link to comment Share on other sites More sharing options...
