Bob Bertram Posted October 23, 2022 Share Posted October 23, 2022 I seem to remember one was called Fat Albert. Quote Link to comment Share on other sites More sharing options...
martin collins 1 Posted October 23, 2022 Author Share Posted October 23, 2022 😅, Your memory is correct Bob, Fat Albert, Fat Annie (one of two survivors) Big Bill, Big John, Big Joe, Big Bill (later renamed Plain Jane) and Porky Pete were the names given by British Air Ferries.

martin collins 1 Posted October 23, 2022 Author Share Posted October 23, 2022 More progress, some of the formers will get lightening holes once they are all in and i see which end is going to be heaviest. Still modifying the plan as i go due to discrepancies and better ways of doing things, it will help when i build the second larger one 😆. Progress being slowed a bit by the modifications and my recalcitrant glue gun! 1 Quote Link to comment Share on other sites More sharing options...
martin collins 1 Posted November 2, 2022 Author Share Posted November 2, 2022 Spent a week or so cutting out ribs, spar parts and l/edge etc but a number of discrepancies and the general vagueness of the plan in that area including what looked like wash in instead of out built into the ribs has made shove the parts in a box and start from scratch on the wings. I am now building them in the style of the ones that were on my Foam board ME 109, with a flat board on the bottom, two foam spars with wood to strengthen and a board on the top with the inner skin removed. It is quick to produce, strong and a lot less hassle, it may be a bit heavier but i will aim to lighten the fuselage in non structural areas to help keep the weight down. Wing bottom skins made and a picture taken to show how small the wing area is compared to the bulk of the fuselage, i am now taking bets as to whether it will fly!!! Picking up some more foamboard tomorrow and i will get the spars made and fitted with the top skin going on Friday. I feel a lot happier about the wings now as i can see how they will work. 1 Quote Link to comment Share on other sites More sharing options...
Eric Robson Posted November 2, 2022 Share Posted November 2, 2022 Hi Martin, the last 3 foam board models I have built all have flat bottom wings and they all fly very well. Quote Link to comment Share on other sites More sharing options...
Paul De Tourtoulon Posted November 3, 2022 Share Posted November 3, 2022 Maybe a few holes in the fuselage bulkheads would get rid of some weight, as above don't bother with washout, you can always put in a bit of up on the ailerons and see what that does.

martin collins 1 Posted November 3, 2022 Author Share Posted November 3, 2022 Circles for holes are already marked on it Paul, last night i was removing the paper with a heat iron on the formers as the strength is not needed there abd once the skin is attatched it will put more strength back. Of course it would have been easier to remove the paper before gluing it all together 🙄. You learn as you go along and in future the paper will be removed from these where they are just used for hanging the outer skin on. Quote Link to comment Share on other sites More sharing options...
martin collins 1 Posted November 9, 2022 Author Share Posted November 9, 2022 Carvair is making progress, redesigned wing is now built. Next job is to make the wing fit the fuselage which was designed to take the previous wing shape, that is tomorrows job . Once that is done the four motor mounts will be made. 2 Quote Link to comment Share on other sites More sharing options...
martin collins 1 Posted November 10, 2022 Author Share Posted November 10, 2022 It fits! Wing now fits the saddle and the rear mount for the bolts is fitted, the front mount for the dowels is going in now, i should be able to bolt the wing onto the fuselage by evenings end. Onto the motor mounts now. 2 Quote Link to comment Share on other sites More sharing options...
martin collins 1 Posted November 14, 2022 Author Share Posted November 14, 2022 Progress update, tailplane sanded to shape and fitted this evening, fin shaped and all hinge slots cut, the fuselage servos will be going in tomorrow. 2 Quote Link to comment Share on other sites More sharing options...
martin collins 1 Posted November 24, 2022 Author Share Posted November 24, 2022 Been busy with another Foamboard project (non flying) which i am making someone for Christmas, i will post on the forum once the present has been unwrapped, just in case the person stumbles across this forum! Back to the task in hand, the fuselage is now finished bar the outer 3mm depron skin, that is the last job on the list. All servos are fitted and fuselage control snakes fitted and connected, i used snake inners as the outer and ran carbon rod through the centre as the control rod with metal ends bound with cotton and epoxy to keep the weight at the rear as low as possible. The motor box skins are now made and fitted, i went off plan here as i had with the whole wing build, my pal had drawn the motor supports as a + section, a vertical and a horizontal with formers round them, my boxes will still have formers but they will need less material, i think this is a stronger method as well. Looking at the motor selection now and will put some thin ply strengthening into the inside walls on the boxes before adding the ply motor mounts to the front of the boxes. 4 Quote Link to comment Share on other sites More sharing options...
Simon Chaddock Posted December 3, 2022 Share Posted December 3, 2022 Impressive. It may be foam but it looks a bit on the heavy side to me. I am always conscious of the fact that full size airliner fuselages are basically hollow tubes! In addition the Carvair was not blessed with the biggest of wings. The final weight and wing loading will be interesting. Quote Link to comment Share on other sites More sharing options...

martin collins 1 Posted December 8, 2022 Author Share Posted December 8, 2022 Not much progress at the moment, time is being used `making` Christmas presents for someone, will post more details on Christmas day! Quote Link to comment Share on other sites More sharing options...
martin collins 1 Posted January 9, 2023 Author Share Posted January 9, 2023 This is what i was busy with on the run up to Christmas plus building plastic model kits of a 1969 Corvette and a Viking longboat for other presents. The wall hang Carvair is made from HobbyCraft foamboard using the main vertical pattern from the R/C Carvair then adding another piece of foam board to make the wing and the tailplane, so it is quite large. The scheme is that of the British United Carvair that our family flew to France on with our Doormobile camper van in the 1960`s, it is now hanging in my brothers entrance hall. 2 Quote Link to comment Share on other sites More sharing options...
