Peter Miller Posted February 11, 2016 Share Posted February 11, 2016 Back in the late 70s I designed a cntrol line stunter called Nebula. THis was a lovely model and great for windy weather. I once flew in a Novice stunt event and afterwards a judge asked me "Do you always fly a team racer in stunt?" I then designed a smaller version for .19 size engines which was just as nice. A few years ago I took the design lay out and designed a .25 powered R/C version. THis was fast. I have flown it in winds gusting up to 30 mph. It didn't half move going down wind on that day!! Recently I have been feeling totally burnt out and lacking in inspiration. and then I tought tht maybe a larger model with a bigger, thicker wing would be nice as I find small fast jobs are a bit hard on these old eyes and fingers. This is the history of Super Marauder FS. Now on to the building. Nice and very simple because I am still lacking in much drive. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted February 11, 2016 Author Share Posted February 11, 2016 The fuselage is very simple butthe cowling gets complicated The box is pretty standard but with 1/4" triangular stock on the edges The underside view Note cockpit floor. The tank is accessable when the cowl is removed. The nose is built with 1/2" sheet grafted onto the fuselage sides At the rear there is a 1/2" sheet tailplane platform. This is used to take the dowels that hold the fin on as we shall see. The sheet tailplane platform fitted. The fuselage with all the bits including the 1/4" sheet top.

Piers Bowlan Posted February 11, 2016 Share Posted February 11, 2016 That looks super Peter - I like simple. I have just started building a Ballerina so I better get a move on as I am sure your Super Marauder plan will be published before my Ballerina is finished. What engine have you fitted?

Peter Miller Posted February 11, 2016 Author Share Posted February 11, 2016 Actually I have another plan waiting t be published before this one so ypu shpould have plenty of time. Engine is an OS FS52 Supass that I bought on Ebay but a 48 or any 52 would do nicely. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted February 12, 2016 Author Share Posted February 12, 2016 The top fitted. The engine has been teporarily installed and the nose ring glued to the back of the spinner ready for shaping View of the underside of the nose before shaping. The nose has been shaped. In the final design the ply doubers will end at F-1, shaping them was a real pain in the derriere. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted February 12, 2016 Author Share Posted February 12, 2016 The fin is vertially just butt gued to the tailplane with very little support. This is a disaster waiting to happen. The tailplane is spot glued down and holes are drilled using an angle guide. 1/4" dowels are glued into the fin and these go through the tailplane and that 1/2" sheet block under the tailplane. Which then seats firmly on the tailplane. There are two very small fairing blocks that just fair the fin into the spine. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted February 13, 2016 Author Share Posted February 13, 2016 The cowling is built from parts cut from the fuselage sides. with a 1/4" sheet bottom, 1/8" liteply duct roof, and ply intake outlines. The two long 3 mm caphead screws hold the cowl on. In side view of the cowl with engine compartment and tank bay.The hard wood blocks just behind F-1 hold blind nuts for the cowl hold down screws. The two hardwood blocks in the cowl are drilled for the long cowl hold down screws This view shows the tank location and the cut away in the duct roof. to clear it. I will have to arrange some shielding as it is possible that the hot air from the engine could make the fuel boil off. I have had this happen with a rear exhaust engine but that was hot. THe fuel boiled out of the vents in a C/L stunt tank in about three laps!! A remote glowplug connector will be fitted in the side of the fuseage.

Peter Miller Posted March 17, 2016 Author Share Posted March 17, 2016 Finally finished the Suoer Marauder. No wing pictures have been posted as they are almost the same as all my others. The model is 58" span, nearly 600 sq in, weighs a mere 5lbs 4 ounces with a wing loaiding of 20 oz per sq. foot. Power is an OS FS 52 . Now all I need is a calm, sunny, warm SUnday to get the test flight and flying shots. OH, and it only needed 2 1/2 ounces of lead in the tail to get the balance right.

Colin Leighfield Posted March 17, 2016 Share Posted March 17, 2016 It's got a bit of the Chance-Vought Crusader/Corsair about it, looks fantastic Peter. Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted March 17, 2016 Share Posted March 17, 2016 Looks nice Peter, I immediately thought of the Spacehound era stunters with the short (by RC standards) tail moment and big chin inlet. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted March 17, 2016 Author Share Posted March 17, 2016 Thanks for the kind remarks As I said, originally the styling staged tout on my contolline stunters from the 70s. I have always thought of a Chnace Vought Corsair in the past I didn't think of it in this case. I always fancied a Corsair with the wing tilt as an R/C model. Must do it one day.

Colin Leighfield Posted March 17, 2016 Share Posted March 17, 2016 That will certainly be a challenge, but why not? Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted April 11, 2016 Author Share Posted April 11, 2016 Well at last we got a decent day for test flying. I took some photos and fellow club member Michael Morris took more. Here at=re the results. Edited By Peter Miller on 11/04/2016 12:48:15 Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted April 11, 2016 Author Share Posted April 11, 2016 The model was flown by myself and three other pilots who all liked it. It is not too fast but will do all the aerobatics you want. Very smooth and spin recovery is instant, doesn't want to stall and certainly does not show any desire to drop a wing.

Jack Banner Posted April 11, 2016 Share Posted April 11, 2016 Looks great, I fancy it would look great with retracts too. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted April 11, 2016 Author Share Posted April 11, 2016 Yes, I did consider that but couldn't find what I wanted. so I opted for the spats to look like drop tanks. Quote Link to comment Share on other sites More sharing options...
Tony Cook Posted April 11, 2016 Share Posted April 11, 2016 Very Nice Peter, new to forum after joining UKCAA, really enjoy the older stuff (must be a sign of getting older) do you have any problems with inverted FS installation? If so what do you do to remedy poor starting/idling? Quote Link to comment Share on other sites More sharing options...
Luther Oswalt Posted April 11, 2016 Share Posted April 11, 2016 That is really nice Peter, Looking forward to plans! Leo Quote Link to comment Share on other sites More sharing options...

Plans will be sent in in a few weeks, juust got to inish the plans and write the text and I have other jobs to da before then. Anyway next month is my Peyret Maubouusin plans in RCM&E.

kc Posted August 10, 2016 Share Posted August 10, 2016 The Super Marauder is one of the free plans in this months- September - issue of RCME. seems a good idea to buy a copy now for the winter building season....... Quote Link to comment Share on other sites More sharing options...
Shaunie Posted August 11, 2016 Share Posted August 11, 2016 For a classic style plane, how about a classic engine, I've got an OS 45FSR that needs a home. Would that be a reasonable match? It is the favourite engine of all that I've owned and deserves a new home. Shaun. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted August 12, 2016 Author Share Posted August 12, 2016 Hi Shaunie. Should be an impressive combination. Probably a bit faster than mine or even a lot faster but that should be no problem. Go for it!! I will look forward to hearing how she goes. I am exgtremely fond of theold .25 FSR and have one in my SWamp Rat Quote Link to comment Share on other sites More sharing options...
john kennedy 4 Posted August 13, 2016 Share Posted August 13, 2016 Hello. I've been out of fixed wing modelling for a few years now but seeing this plan in a copy of RCM&E I bought whilst on holiday I decided I had to get back in and build this beautiful simple (?) model. I am looking for advice as to how the wing is built. I am concerned about building it flat with no unwanted twists. As the wing tapers slightly towards the tip,would it be better to to place a tapered packing piece,at the T.E. on the board to counteract this? As I am going to fit retracts I will need to build it slightly differently to keep the bottom sheeting off til I've sorted them out. I am hoping that Peter or anyone else might have some photos of this or similar wing builds to assist me. Thanks in anticipation ..

trebor Posted August 13, 2016 Share Posted August 13, 2016 Watching with interest, I need a suitable plane for windy conditions. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted August 13, 2016 Author Share Posted August 13, 2016 Hi John. The wing sequence in the instructions works perfectly as described and guarantees a perfectly true wing. Now you will see that I fitted the U/C mount loosely on top of the bottom sheet, then added the wing ribs and then lifted the 1/4" ply U/C mount up and glued it ti the ribs as the lower sheet was raised to fit the underside of the leading edge. I used exactly the same method when I built my Dalotel with retracts for R|/C Model World. So cut your ribs to suit the retract bearers. Lay them down instead of the 1/4 ply U/C mount and then carry on with the sequence. Once you have completed the wing you lift it from the board and cut away the sheet for the retracts. Trust me, it works. I shall be using the same method on my next scale model which also has retracts. Quote Link to comment Share on other sites More sharing options...
