[repair aerial lead]

Thanks Geoff,the wire is about 43 inches will check it again to make sure

[repair aerial lead]

Thanks Kc ,yes I did miss kens offer ,not easy on this iPhone .

Ken will pm you later when I have worked out how to do it

Thanks Martin would speaker cable be ok ,pull off the other wire,otherwise I can try my thicker cable,then give it a good range check.

I need to solder on a new aerial to my futaba receiver does it need to be thin wire as all I can find is twice the thickness

[Mick Reeves Gangster 63 electric conversion]

Hi gangster my motor is an Emax BL 2820/07 with a master air screw 10x5prop

the model has a 63 inch wingspan possibly 20 /30 years old given to me by a friend of mine

[Mick Reeves Gangster 63 electric conversion]

Not flown yet,but want a bigger motor ,anyone know of a suitable make and size of motor for my gangster,do I need 100 watts per pound?don’t want anything too fast.

[Joining the wings sig 1/4 scale cub]

Whoops ,incidence is the angle of atack on wing,should have said dihedral,

[Joining the wings sig 1/4 scale cub]

I have pushed the wings up tight to centre section,put some heavy batteries on the centre section,which gives me just under 1/2 an inch under each wingtip,will block up wing tips at 1/2 inch before glueing.

so that works out at 1 degree of incidence according to my calculator.will get my evostick wood glue out tomorrow and glue it up.

[Joining the wings sig 1/4 scale cub]

Thanks John I shall probably stick with the wood glue,I think the dihedral was 1 1/2 inches under each wingtip.

Thanks for the download instructions Martin not sure if I have got this wrong,both wing ribs for joining are at 90 degrees,should the wing rib w1 have been glued later,got a photo now at last not sure how I got it here though.

[Joining the wings sig 1/4 scale cub]

Danny,i believe the model cub flies better with a bit of dihedral.I did take some photos but couldnt get them off my iphone on to here,will try again,much easier on my laptop.

John ,im still at it still building,that sounds a better idea better than filling it with araldite,should i join the left hand wing to centre section with my wood glue (green bottle) or araldite,doesnt seem strong enough to me,needs strengthening,i suppose the struts may help a bit.

Hows your cub coming on?

Chris

[Joining the wings sig 1/4 scale cub]

Hi,i am building a sig piper cub 1/4 scale now got as far as joining the left wing to the centre section,problem is there is a gap at the back between the two wing ribs i am about to glue ,and the wing looks flat , not much dihedral, should i use epoxy resin araldite to fill in gap or put some balsa in there and block the wingtips up for correct dihedral

[Motor squealing at full power]

First thing i shall do is swap the ESC,then try some 3 in 1oil,if all that fails it will be another motor.

That was interesting about soaking the bearings etc,I don't think I shall go that far.

[Motor squealing at full power]

Probably is the blue series,I have found the instructions for it,but it doesn't tell you much,some of them look really complicated.How can I put a photo of it on here,years ago I used to use photo bucket.can I do it direct off my iPhone..?

[Motor squealing at full power]

Just been in workshop, its a Hobby King 35 ESC, but its a 15volt 4 cell,Ive been using it on a 3 cell ,would it make any difference?

[Motor squealing at full power]

Thanks for all your replies,I don't know anything about ESC timing so first thing I will do is google it as Dennis said,the ESC is not a very good one it came with a plane I bought,should have the instructions still in workshop.

I have a few spare ones so might just swap it over,would be nice to reset the timing though.thats if its not incompatible with the motor.

[Motor squealing at full power]

I have a low wing model with a brushless motor which squeals on full power,as you throttle back it's fine but every now and then it cuts out for a second or two and then it's ok for a few minutes.ESC is cool .

[cutting 3 mm balsa and ply to fit servo]

Hi Keith,I started on it back in May when it came out in the RCM&E magazine.not done much on it lately though,most of the fuselage is done working on the wing now,I have very slow broadband here ,having problems posting .

Chris

[cutting 3 mm balsa and ply to fit servo]

Now that's the way to do it,your servos are a bit bigger than my 9 gram ones,perhaps I should have used the Morticer might try it later.

[cutting 3 mm balsa and ply to fit servo]

Just tried the cutting wheel in the Dremel worked really well on the ply and balsa,just needed my modelling knife to do the corners,off to get some fine blades for the power scroll saw now,

[cutting 3 mm balsa and ply to fit servo]

Thanks for your replies,i would normally use the power scroll saw ,but on thin balsa it rips it up badly I need a finer blade,same with the fretsaw,the cutting wheel in the Dremel sounds a better idea though I will try it now ,should have a small cutting wheel in the workshop.

[cutting 3 mm balsa and ply to fit servo]

I am building a Chica from plans ,I need to cut some square holes in 3 mm balsa and 3mm ply what is the best way to cut it,

Chris

[Chica 3mm ply or 4 mm does it matter?]

Thank you for all your replies,the lightening holes sound a good idea ,good for the elevator pushrods ,aerial cables etc ,glueing sheets of balsa and ply together sounds good too,must find the plans and have a good look at them.

[Chica 3mm ply or 4 mm does it matter?]

I am thinking of building the Chico from the free plans May, from scraps of wood in the workshop,i have plenty of balsa but no 3mm lite ply for the formers, can I use 4mm ?or would that be too heavy.

[motor cutting out]

Thanks Ben,I shall try that ,I shall strap it on with some masking tape or elastic bands.

There isn`t much room in the fuselage so it would get quite hot ,better check the battery as well.

[motor cutting out]

I have a Bixler 2 and brushless motor with a Go Pro camera on the front,It has loads of power for taking off ,but once your up in the air and you ease off the power it starts cutting out,its full power or nothing.

On the ground its perfect no problem,

Chris
