Peter Miller Posted November 11, 2012 Share Posted November 11, 2012 Having built the CAP 20L. I needed something to replace the Minnow that got demolished when I managed to switch the tarnny off whil;e reaching for the elevator trim. This is the story. Basic fuselage structure. The top sides added/ Underside. Note the blocks in the silencer area. Top sheet completed and cowl being built round the engine. Looking inside to see the U/C mount. Another view of U/C mount and silencer cut away. Close up of cowl being built. Engine being mounted temporarily. See silencer recess.

Peter Miller Posted November 11, 2012 Author Share Posted November 11, 2012 Now on to the wing The basic wing being built over the lower sheet. Top sheet being added to one wing. The other wing being built, Note that R-1 is not fitted to this wing at this stage. Complete left wing being joined to right wing. Right wing R-1 is added now. CLose up of Dihedral joint being made. CLose up of Bellcrank bay. Slot allows pushrod to be fitted after covering. makes life easier. Complete wing ready for covering. Close up of Aileron servo bay..

Peter Miller Posted November 11, 2012 Author Share Posted November 11, 2012 And today, with perfect conditions and wall to wall sunshine we took her flying. About 53" span. SC 32. Weight 4 lbs 6 ounces. Quick, easy and doesn't look too bad. Very fast, very aerobatic. I need to reduce aileorn and elevator high rates. Coming to pages near you one day.

Andrew767 Posted November 11, 2012 Share Posted November 11, 2012 Peter....I love your designs..but....could you please design them with removable cowls, so that those of us of a lowlife electric persuasion could do an easy conversion...Lol!! Kindest Regards Andrew Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted November 11, 2012 Author Share Posted November 11, 2012 I design them so I can get at the engine. There is a very simple way to make a removeable cowl. Make the cowl as shown but complete without cut outs. Put a facing of 1/16" ply on the rear face. Make small grooves in about three places and screw the cowl to F-1 with old servo screws. You could even make keyhole slots and just slot the cowl over the over the screw heads Edited By Peter Miller on 11/11/2012 19:49:09 Quote Link to comment Share on other sites More sharing options...
Myron Beaumont Posted November 11, 2012 Share Posted November 11, 2012 Peter Nice one .When will people realise that you just love proper engines? By the way,not like you not to have the engine mounted at 45 degrees is it ? Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted November 12, 2012 Author Share Posted November 12, 2012 Thanks Myron. No, the engine mounting is a new idea. Came from my scale Stits where I wanted the engine to replicate the original flat 4. On narrow fuselages it is quite easy to do and looks so much neater.

Chris Bott - Moderator Posted November 12, 2012 Share Posted November 12, 2012 Here's another way to do an electric installation Andrew. Removing the 4 screws that hold the motor to the X mount means the motor can be removed through the hole at the front. Another nice design by the way Peter.

Eck Posted November 12, 2012 Share Posted November 12, 2012 Very nice....Like a nicer Acrowot. Oodalally? isn't that from Disney's Robin Hood? Quote Link to comment Share on other sites More sharing options...
JohnnyB Posted November 12, 2012 Share Posted November 12, 2012 WOW Peter, your design and build output is just phenomenal!! How many designs have you created? Just out of interest, have you ever designed a model that proved too difficult to fly.... John. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted November 12, 2012 Author Share Posted November 12, 2012 Oodalally is from Robin Hood. an exlamation that can be excited, happy or dismayed. Very appropriate for modellers. About 150 published designs. I haven't a clue how many in total.. My recent Stits Junior was flyable but only just. it crashed on take off twice out of six take offs. Once in the air it wasn't bad. A couple of others which failed due to a wrongly located CG. Needless to say not published. Got a drawing for a TD 049 powered glider to finish off now....

kc Posted November 12, 2012 Share Posted November 12, 2012 A very nice model......when is it going to be published? I just noticed the size amongst the photos........ just the right size! Edited By kc on 12/11/2012 11:36:50 Quote Link to comment Share on other sites More sharing options...

Peter Miller Posted November 12, 2012 Author Share Posted November 12, 2012 Graham Ashby has my CAP 20 L: on file. this one will be sent in soon. then it is up to the editor. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted November 12, 2012 Author Share Posted November 12, 2012 Well, I can certainly say that it flies right. IT is very close to Minnow but low wing and one or two other very slight changes to moments and wing section. so I knew it would be pretty good before I even flew it.

kc Posted November 12, 2012 Share Posted November 12, 2012 I know that Peter really prefers IC powered models however there is a growing trend towards electric especially amongst newer recruits. Therefore it would be nice if some of the free pull out plans showed a revised front end for electric power too. In this case I suppose the engine bulkhead would be needed further forward as the motor is shorter and space is needed behind for the Lipo. It wouldn't take much extra space on the drawing to show this option together with a top hatch for Lipo access. It is so much easier to build exactly to the plan rather than modify it yourself if you are a newcomer. Frankly we need to do everything to help & encourage the new recruits to build their own models and if this means giving details of electric conversions ..... Otherwise they wont buy magazines but buy ARTF from the websites....... Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted November 12, 2012 Author Share Posted November 12, 2012 Some of us don't know what size the electric motor would be, or the batteries so it would be very hard, if not impossible to draw up an alternative front end and be sure that it is right. I suppose I could draw it up for a Speed 600 and a 7 cell Nicad but I don't think that would work to well on a model intended for a .32 ic engine.

Stephen Grigg Posted November 12, 2012 Share Posted November 12, 2012 When you get ARTF now they often have an electric kit which consists often of nuts and bolts to fit onto the firewall.In building a model like this using the space for the fuel tank could be modified to take the battery iexpect amd making a battery hatch would be straight forward..Most shops now can sell an equivalent electric motor,and using 100 watts per lb would also give the size required.

Peter Miller Posted November 12, 2012 Author Share Posted November 12, 2012 Sounds good. Then the builder should be able to get all the information he needs. As a point of interest, very few poeple build models without some modification however slight. That is the very first step to learning how to design one's own model. However I have just bought a Wankle engine. my plan for that will show a conventional engine and the Wankle. Wankles look like brushless motors. Problem solved.

Jimbo565 Posted November 12, 2012 Share Posted November 12, 2012 Peter No I have not seen your Dragon Dancer 2 because I went from page 63 straight to page 70 and the pension does not hit the bank until Friday. No doubt I'll have a look at it then and have it built by the following Friday and the Friday after, Doolally will be under way. Just keep em coming Quote Link to comment Share on other sites More sharing options...
