Bob Cotsford Posted August 8, 2009 Share Posted August 8, 2009 I do like a nice bipe, and that's a nice brace of bipes you've got there Stephen. The Stringalong has more than a touch of the Curtis Hawk about it. Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted August 8, 2009 Author Share Posted August 8, 2009 Hi Bob you might be closer to the mark than myself,the reason Ive called it the Stringalong is because there is a card in the model that states Stringalong on it.Ill probably find out more from the experts at the field tomorrow Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted August 8, 2009 Share Posted August 8, 2009 nah - it's just had the cowling and colour scheme styled on the between wars American fighters such as the Curtis 'pursuit ships'. http://www.myhobbystore.com/1525/Colyer-RM5---Stringalong.html Quote Link to comment Share on other sites More sharing options...
PatMc Posted August 9, 2009 Share Posted August 9, 2009 Stephen, I'm pretty sure that is a Stringalong. It seems to match the picture in an old RM plans catalogue. It's rated to be able to fly on rudder & elevator only. Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted August 9, 2009 Share Posted August 9, 2009 sorry if I confused anyone, I meant, yes it's a Stringalong, but with the cowling shaped to resemble that of the yankee between war fighters fitted with V or W congiguration engines - see the link in my previous post to the plan ad!Edited By Bob Cotsford on 09/08/2009 10:18:40 Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted August 9, 2009 Author Share Posted August 9, 2009 Yes the chairman of the club confirmed its definitely a Stringalong that the guy has modified.The most obvious 1 is the engine is fitted much lower so he altered the thrust line.The model flew beautifully,and the Murco 61 performed well Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted August 10, 2009 Author Share Posted August 10, 2009 After arest from a very early start(some work to get out of the way,and a full day at the field,I started on the high wing trainer.I think the previous owner had a standard removeable servo shelf he used in the next models as he finished using one and went on to the next.They have nothing in them so I have to build servo mounts from scratch.Having now done a couple its become straight forward.The 3 servos for throttle rudder and elevator fit along side each other so I have to build a support for the shelf so its at the correct height.As in the days these were originally built the radio system was so basic,the accuracy that had to be used then makes it easier now with the radio equipement we have now making it possible to trim the models controls so much more now.On the first model It took 3 evenings of experimenting before I got ot right,this one took an hour.Ive just the scews to fix the servos in and then the wing servos.This one has flaps ,new territory again for me,so that should be fun.I was going to do the Blue Bipe next but the demise of my Mentor has brought this one forward.Hopefully the fir.st low winger will be done for next weekend Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted August 10, 2009 Author Share Posted August 10, 2009 Spent most of the evening trying to get the throttle linkeage set up satisfactorily.Started off to long but by locating a shorter clevis finally managed to get it right.The rudder and elevator were a doddle.Bit stuck on the Aileron and flap sevo position.The bend on rhe connection appear to be 90 degrees wrong.Ill look at another wing that has a servo on it .The other models appear a fairly straight forward fit.

Stephen Grigg Posted August 11, 2009 Author Share Posted August 11, 2009 The firat pic is the model,2nd is the aileron and flap wires and 3rd the way Ive fitted the Servos inside Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted August 11, 2009 Author Share Posted August 11, 2009 Today at the field I flew the Stringalong,and th e Small Biplane in Swedish colours.The Stringalong is lovely,the little biplane takes foreever to turn so weve given it more rudder/aileron mix Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted August 11, 2009 Author Share Posted August 11, 2009 This evening seems to have shown a problem that my in experience isnt sure how to get around.The wing For the high wing trainer has no way of getting into unless I damage it.The problem I have been unable to solve is the aileron connections go left to right at the same time to go up and down in opposite directions.So when Ive connected a Servo in the normal way,the ailerons go up and down in the same direction,so both up or both down.Any ideas how I get round this please?

Stephen Grigg Posted August 12, 2009 Author Share Posted August 12, 2009 Funny how sometimes you wake up with the answer,and when you do its obvious,find out tonight if Im right Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted August 12, 2009 Author Share Posted August 12, 2009 Before coming to work I just had to try the way I thought would work,and it did.A full circlethingy on the sevo cut down to a quarter worked a treat.The 2 pics show the right way and the wrong way This one is the right way,and yes I know that its got fixes and screws missing.I now have to fit them on to the servo,then glue into place are cant reach afterwards Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted August 13, 2009 Author Share Posted August 13, 2009 Finished the Aileron servo last night successfully,tonight is the flaps servo which will see this model ready to fly.Ive brought the blue bi-plane called the Pasadena Special home to start tonight as well.

Stephen Grigg Posted August 14, 2009 Author Share Posted August 14, 2009 Managed ro get nothing done last night.My mate brought the first low wing trainer back this morning still alot to do on it but he has run out of bits.But it shows me what I have to do with the flaps on the trainer.I coulnt find a mount for the engine,but Ive got one in number 6 model so I can use that as a pattern and then use it in the blue bipe ,so plenty to get on with Quote Link to comment Share on other sites More sharing options...

Stephen Grigg Posted August 15, 2009 Author Share Posted August 15, 2009 Spent the evening trying to remove the engine mount from No6 model.I I was totally restricted by space and could only find 1 screwdriver that I could reach the bolt heads through a small hole,but managed in the end. can now do 2 things drillholes in the mounts I have and try and locate a couple of original mounts.I was then able to test fit the engine intended for the Blue Bipe,its to big.An OS 40 fits perfectly but I need at least a 46 2 stroke.There isnt room for a 4 sroke to fit unfortunately, Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted August 15, 2009 Author Share Posted August 15, 2009 I ordered an SC 52 2 stroke from Galaxy for the Blue Biplane.today.This is the biggest engine that will fit the engine mount and engine bay,so it should have enough power.Ithen fitted the engine,an OS 30 Max into the low winger,very fiddly,no room,and akward angles to put the screw drivers,but managed to get it all connected up eventually and the thottle servo moving the throttle correctly.The only hold up now is the switch.The sides are very thick ,the original placewas inside but the switches I have arent tall enough to drill a hole in to fit a rod to operate from outside Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted August 16, 2009 Author Share Posted August 16, 2009 When I was at the Bring and buy at the start of the year I bought some draws full off bits and bobs.I searched through said items and found a switch extension I think will do the job.So after work I hope to finish the low winger.

Stephen Grigg Posted August 17, 2009 Author Share Posted August 17, 2009 Finished the low winger tonight,Made the mount for the high winger Flaps ,anly need gluing and screwing and thats ready as well,.Aiming to fly them Tuesday. Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted August 18, 2009 Author Share Posted August 18, 2009 Flew the low winger today and it flew superbly,thats noe 3 into the air,and no dramas,the gent knew how to build them Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted August 18, 2009 Author Share Posted August 18, 2009 The good news is the SC 52 2 stroke arrived this morning.The bad news,it will not fit.Because of the way these models are built the engine fits into the cowl which is part of the fuselage.I have to fit the engine mount in to the fuselage first and the metal engine mount is threaded to take the engine bolts.There is no way to fit nuts and bolts.The engine mount is solid at the back where it fits the bulkhead.New engine mounts have a gap where the holes to mount them are drilled.I cant drill fresh holes because I cant get in there..I think Ill have to take the engine mount to a model shop and match the most powerfull engine to the mount and take it from there.

Stephen Grigg Posted August 18, 2009 Author Share Posted August 18, 2009 Ive taken the measurements of the SC52 2str, 35mm and the mount I have 33mm.Ive checked a number of mounts, and they are also 33mm.There must be a point where the engines go from 33 to 35,and possibly different makes are different widths Quote Link to comment Share on other sites More sharing options...
