Silver Wolf Posted October 18, 2014 Share Posted October 18, 2014 Started modeling in 1989, where I started with a DB Mentor kit (built on lap in the front room, wife not impressed). After that the box room was converted to a hobby room and a Trenton Terror (vintage kit) being built. This was followed by a plan built DB Aerobat which I would recommend as a follow on from a trainer, although small it would fly in all weathers. I then built a Cessna from an Eric Fernley plan, this model was built with no real detail but was a considerable step from the plans and kits I had built from. Not really understanding the importance of wing incidence or engine thrust lines, I continued and completed the model; the test flight did not last for long. It was after this experience that I started to try and learn a bit about model aerodynamics so I could understand what had gone wrong. I think that incorrect engine thrust line and too much positive wing incidence lead to a stall on take-off. So it was back to sports models (sig Astro Hog) this was built very accurately and measured during the build (lesson learnt), this model flew as if on rails. Several other models have been built since (loft converted to model room) and with each one I tried to learn something new either being in the build or type of model. And because off lessons learnt from the Cessna I do not tend to dread a test flight although always slightly nervous. This brings me to my current situation where I have not been really been active with my flying for more years than I would have liked, due to family and major DIY after house move. I have always been interested in scale but never successfully built or flown anything scale, the exception being a Cambrian fun-fighter. The sabbatical for family and DIY lasted for nearly 16yrs with very little flying and or building (where does the time go?). So at present I am back to a trainer and circuit bashing intend to get to the stage where I can be reasonable at completing the ‘B’ schedule. I intend to try flying pattern aerobatics, the intention being that if I’m comfortable with aerobatics then flying the scale models will be a little less stressful. Although the sabbatical was longer than I thought it ever it would be, it has left me with a greater desire to do build and fly scale models. My aspiration is to get to the stage where I can attend a scale fly-in with out being ashamed of either build or flying quality. Ideally I would also like to aim towards competing at the Nat’s. Intend to start the build at the end of October once the clocks change, there a couple of things that I would like to complete first. I have a flair Legionnaire that I would like to get covered, the small amount of detail can wait until after test flight. A SAS wildthing, this will hopefully help keep by hand in with the sticks once the weather turns? So why the chippy, well I have the RM plan that I had intended build, but have heard that there may be errors with the plan, so this was then relegated down the build list. So when this build appeared, it seemed that fate has taken a hand. So at some time in the near future I would like to end up with a model version of this.

john stones 1 - Moderator Posted October 18, 2014 Share Posted October 18, 2014 Hi S.W All sounds familiar, improving your flying will certainly help with scale models, they tend to have a few quirks The legionnaire is a nice model you'll enjoy it, it can be a bit naughty on the floor though (ground loop) Nice colour scheme you chose John Quote Link to comment Share on other sites More sharing options...
Nigel Day Posted October 18, 2014 Share Posted October 18, 2014 Yes, nice colour scheme SW. I think Danny F quoted someone saying that the scale stuff is 2/3s of the work. Not much for us to learn then! Quote Link to comment Share on other sites More sharing options...

Silver Wolf Posted October 18, 2014 Author Share Posted October 18, 2014 Thanks for that, hope I can do it justice. Build will be a bit of a challenge but the really work will start after basic air frame is completed. I plan to post my objectives for this build/blog just before I start and try and catch up with others. At present enjoying lurking and getting inspiration from all the other blogs.

Danny Fenton Posted October 20, 2014 Share Posted October 20, 2014 Good to see your build blog start SW, its an interesting build, but I think you will be able to cope reading your modelling history I look forward to seeing how you get on, any probs let us know and we will try and help. Have you thought where you will start? Cheers Danny Quote Link to comment Share on other sites More sharing options...
Silver Wolf Posted October 20, 2014 Author Share Posted October 20, 2014 Hi Danny, I normally start with tail feathers, which most people have done already. I then normally do the wing then the fuselage last, this allows that any adjustments for wing and tail feather alignment can be done to the fuselage quite easily. Hope to get further with this than my BT Kingfisher (tail feathers and two part complete wing panels). Although to be fair the only reasons that I stopped that build was due to a 4yr garden project (wife is happy though). I would have restarted the Kingfisher now but you came along with this chippy build and I think I (we) will learn quicker following you and other experienced builders. Also a great believer in fate. Hope to be able too meet some fellow chipertee'rs at Gaydon. SW Edited By Silver Wolf on 20/10/2014 09:56:51 Quote Link to comment Share on other sites More sharing options...
Silver Wolf Posted November 23, 2014 Author Share Posted November 23, 2014 A bit later start than planned, well a lot later considering that there are quite a few chippys that are nearly built. So what do I want to achieve with build? I intend this to be a model that could be used for flying only competitions and maybe a first attempt at stand (way) off scale. It will be interesting to see how long the airframe takes, past models have taken years for various reasons and I hope that by doing this blog this will change this into months. So my objectives are as follows Regular updates to blog (first blog) Air frame to be built within 4 months Flaps (first model with flaps) Some cockpit detail Scale like undercarriage (maybe oleos) Surface detail (limited to give effect as this is intended to be flying only) SW Quote Link to comment Share on other sites More sharing options...
kc Posted November 23, 2014 Share Posted November 23, 2014 Presumably you are building the Dennis Bryant Chipmunk like lots of other people, however the heading says Chipper-too which seems very like Chippertoo which is a different plan by Brian Peckham RM219 from MyHobbyStores. The Chippertoo looks rather like a Super Chipmunk but I think its just a sports model and not really scale. Could be confusing! Note there is another Brian Peckham design with a very similar name -Chipperoo RM129. again a Chipmunk lookalike but just a sports design.

Silver Wolf Posted November 30, 2014 Author Share Posted November 30, 2014 Up date for wk1. Rudder built, but needs to be sanded once fin has been built. Fin LE has been laminated and has stayed in shape. A new tail plane spar as been cut (as John suggested) due to the original been warped. I did try to remove warp after soaking it in water and pinning to building board. This had little effect in fact it made it worse. A little frustrating this week has i hoped to have progressed a bit further. It also has become apparent that my expectations far outweigh my building abilities, however i think this will change as the build continues. It has been quite a while since i have done any building and i know i that i have learnt a few lessons in just building the rudder.

john stones 1 - Moderator Posted November 30, 2014 Share Posted November 30, 2014 Yep that spars bent rudders very tidy SW, looks like you can build to me John Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted November 30, 2014 Share Posted November 30, 2014 Ahhhh SW all the tools lined up! a man after my own heart Great start, it gets quicker and you will get back into the swing of things I am sure. It took me two rudders before I got going Looking forward to following along, keep those pics coming Cheers Danny Quote Link to comment Share on other sites More sharing options...
Silver Wolf Posted December 14, 2014 Author Share Posted December 14, 2014 Fin now built but will leave rounding off the LE until ready to assemble to fuselage. To get an even surface for the sheeting i tend to use a sheet of sandpaper double sided to a bench or large sheet of MDF. Even after reading blogs did not check rudder thickness (doh) and guess what? Need to added some material but now have a rudder that matches the fin. The laminated and pre bent LE for the fin worked a treat. I have given the leading edge an initial rounding and have yet to fit the shrouds, how much movement is required for the rudder and how much overhang for the shroud? The tail plane has been made (built vertical)but that caused quite a few steepness nights on trying to get rid of a small warp (only a 1mm at the centre) after adding bottom sheeting. I soaked with water and pinned to the board, also done the same whilst using ammonia. Without the LE or the sheeting it is very delicate! After much deliberation I decided to fit the top sheet and have another go at getting rid of the warp and unless it got worse would try to live with it as it was very small. After using plenty of clamps (thanks to seeing those on other blogs) and some substantial timber we ended up with a nice straight tail plane. Reasonably happy with tail plane so far (If I trouble with tail plane can't wait for the wing) and will start the elevators next week. I have already made the joiner (silver soldered) and its not to bad. After Xmas will have a different camera then hopefully some of the close ups will be in focus. The only trouble with that any dubious building will be there for all to see. If anyone has the details for the amount of movement for the control surfaces then that would be really helpful.

john stones 1 - Moderator Posted December 14, 2014 Share Posted December 14, 2014 Moved on a bit SW it all looks good, as to control surface movements, I like plenty but it would be worth asking the question on the Airsail chippie thread maybe, for a starting point John Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted December 16, 2014 Share Posted December 16, 2014 Hi SW On the Airsail Chippie its R 30mm each way, E16mm up/down, A 14mm up/ 10 mm down, flaps I think is 30 degrees (not sure about that one ) John Quote Link to comment Share on other sites More sharing options...
Silver Wolf Posted December 26, 2014 Author Share Posted December 26, 2014 Hi John, Thanks for the information and apologies for not replying sooner. I have also done a bit of research and according to the pilots manual for the chipmunk the control movements are as follows. Aileron up 21˚ down 16˚ Flaps 15˚ and 30˚ Elevator up 38˚ down 15˚ Rudder 31˚ each way After transferring the angle for the elevator to the plan 38˚ seems to be quite a lot? A rough check for the ailerons give 20mm of up movement for 21˚. It would seem that if 38˚ was used that would give nearly 50mm of movement It will be interesting to see what we actually end up with, at the moment I would be thinking of those airsail movements. I daresay we will have a few maiden flights from others before i have to make any decisions. Anyway not any chance of doing any building today, off for another dinner!!

Silver Wolf Posted January 13, 2015 Author Share Posted January 13, 2015 Fin and rudder now complete with shroud. Using the technique that Danny showed was very effective Generally quite happy with overall appearance, however the transition from top of fin to rudder seems to be about 1mm. Not sure if this is and the general fit of the rudder/shroud or correct. Not sure if any further work will be done on them as the intention is for a stand off scale, however lesson learnt. Just about to fit shroud to tail plane but will await any feedback so that the evevator/tailplane transition is correct. In the mean time will start to have a look at the wing.

john stones 1 - Moderator Posted January 13, 2015 Share Posted January 13, 2015 It looks o.k to me SW, it's a compromise getting a nice fit/look and enough travel on the control surface John Quote Link to comment Share on other sites More sharing options...
Andy Muckley Posted January 13, 2015 Share Posted January 13, 2015 Hi SW looks good to me too, 1mm is ok as you will half that when you cover/glass the fin and rudder Quote Link to comment Share on other sites More sharing options...
