john stones 1 - Moderator Posted August 28, 2018 Author Share Posted August 28, 2018 Started to assemble it now I have the motor, wing has flaps, these are droop down with a hinge on the lower wing surface, can find no hard points to accept the screws and the hinges are poor plastic ones that look unfit for purpose. Any ideas for an alternative method ? Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted August 29, 2018 Author Share Posted August 29, 2018 It sumat I said ? What is laminating film, will it iron on ? Apart from cutting and fitting hard points for screws I'm stumped. Quote Link to comment Share on other sites More sharing options...

john stones 1 - Moderator Posted August 29, 2018 Author Share Posted August 29, 2018 Poked it with a pin, feels little there to fix hinge to, trying to avoid cutting in from the underneath if i can. Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted September 8, 2018 Author Share Posted September 8, 2018 Well I'm still stuck re the flap hinges, tried to cut a slot and fit fluffy hinges, spars rock hard so I gave up. Fitted the tail wheel bracket, nice bit off kit n lighter than it might look. Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted September 8, 2018 Author Share Posted September 8, 2018 Push rods in loose ready for rudder elevator, two servos needed for elevators, seems daft to me I might join them. Don't like the fitted ply trays for your gubbins, takes all the useful room up and stops you using the weight to balance it. Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted September 8, 2018 Author Share Posted September 8, 2018 After much pondering settled on an NGH 17 petrol for it, size was right and weight is good, are they any good ? we shall see. Few pictures, fitted in pretty well and not spoiled cowl too much, may end up with a wrap around silencer yet, cowls only taped on as yet, so ignore the cockeyed look.

stu knowles Posted September 8, 2018 Share Posted September 8, 2018 Hi John. Seagull Models have both a web site and facebook page. It might be worth posing a question there about the flap hinges?? Quote Link to comment Share on other sites More sharing options...

Biggles' Elder Brother - Moderator Posted September 8, 2018 Share Posted September 8, 2018 Hi John, sorry I missed this first time round! Re your flap hinge issue I can only think of two options, neither that brilliant! 1. Use screws that go through the trailing edge and poke out the other side. Fix the to a plate there. Popular ARTF solution of course. Not the neatest but simple and it will probably work fine. 2. Cut a square of film off, then make a shallow rebated square in the trailing edge, time cnsuming but not that difficult. Then glue a plate of hardwood or ply into the square recess. Effectively making a hardpoint. Recover that bit with an offcut of film. BEB Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted September 9, 2018 Author Share Posted September 9, 2018 Hi BEB, I may have had a brainwave (don't all laugh) thinking of making f/glass hinges same as is used for control surfaces, then slotting them in with a bit of reinforcing, it's underneath so I won't spoil the look too much, the supplied hinges want binning. Just got to scrounge some f/glass now. Quote Link to comment Share on other sites More sharing options...

john stones 1 - Moderator Posted September 9, 2018 Author Share Posted September 9, 2018 Posted by iqon on 09/09/2018 13:12:36: Is there anything you like about it. There's lots I like, it's lightly built, colour schemes good, it'll be fun to fly, it's built straight, wings two piece so easier to transport, its petrol so cheap to fly and not much to carry, glazings fitted already, engines easy accessed, no fffafing about to get at choke/plug or keep an eye on fuel tubes, I'll get 20 minutes flight times, will be a good winter model, no one else at club has one, I got it at a good price, it's a Cub so it'll irritate you.

john stones 1 - Moderator Posted September 13, 2018 Author Share Posted September 13, 2018 Been doing a bit, I'm ready to hinge the flaps, but unsure of myself, the flaps have square edges and droop via bottom hinges, supplied ones I don't like, and they're screwed into soft balsa. Plan is to make fibre glass ones and slot the wing/flap to fit em, I will fit these over hinge line and as low as possible, but it will mean there's a gap, this going to be a problem or is it common on scale models ? ignore the mock up hinge it's for question only.

Any ideas for an alternative method ? John, what happens if you slide the hinges forward so that the part fitted on the flap comes up to the flap leading edge? Looking at the design of those hinges I'd expect them to be fitted so that the flap swung down under the wing as it lowered wiith a gap between the two. Have a poke for a hardpoint on the flap leading adge and an hinge width forward of the wing trailing edge. Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted September 15, 2018 Author Share Posted September 15, 2018 Only finding they fitted balsa Bob, I'll leave it till last, getting on my wick. What's the thinking with flaps re servo speed, do you folks put a slower speed in Tx ? any advantage to be had doing it ? Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted September 15, 2018 Share Posted September 15, 2018 I use a rear rotary control for flaps and rely on my finger for speed control. Edited By Bob Cotsford on 15/09/2018 21:15:35 Quote Link to comment Share on other sites More sharing options...
ASH. Posted September 15, 2018 Share Posted September 15, 2018 There's much advantage in slowing flap servos. It prevents any sudden change in attitude and so looks much smoother. Also, the model does not have to be slowed down esp using half flaps. And it looks so much nicer - like full size. I put flaps on one switch - half flap and full flap.

john stones 1 - Moderator Posted September 15, 2018 Author Share Posted September 15, 2018 Idea of how much to slow servo, or it suck n see ? Quote Link to comment Share on other sites More sharing options...
ASH. Posted September 15, 2018 Share Posted September 15, 2018 About 4-5 seconds up and down.. you don't want it to take all day! Flying with half flaps down is so nice for slow scale flying. It will save some electrons as well. Edited By ASH. on 15/09/2018 22:21:14 Quote Link to comment Share on other sites More sharing options...
