WOT 4 Build Help

[Bruce Richards]

Hi,

I am building a WOT 4 for my son (Christmas present) and was wondering what to cover the fuselage with. I do not really want the mess bother or weight of glass and resin can I just cover with profile or similar?

I am worried that the fuz will be too weak with just a film covering.

I would be grateful for any suggestion of other methods I could use and the pros and cons of them. If you think that glass and resin is best I am happy to give it a go.

 I will be fitting an ASP 52 2stroke engine and have gone for 2 servos in the wing.

Any other hints and tips gratefully received. 

Thanks for your help

Bruce - a covering of solarfilm will be just fine. I've built two Wot4's and the airframe is very strong so don't make it more complicated than you need. The ASP will be great. Build her well and you'll have a model that'll last for many seasons.

My friend has a second hand Wot 4, is was a bit tatty when he bought it, apparently quite well used, he spruced it up a bit, cured an aileron flutter problem and has flown it for about 5 years, this year finally saw the demise of his engine - an OS 46. He replaced the engine and it is now flying like a bird again!

Monty, I have a second hand wot 4 that I am very pleased with. It also had a flutter but on the elevator. It was a loose connecting rod between the two elevators. Now its fixed and the wot 4 flys really well. Bruce

Nothing against the WOT 4. But flying one for five years or more, with all the duff repairs and stress of rough landings,  makes a potential hazard to other flyers on the strip.

need some advice please

I am building the wot 4 myself, just at the stage of installing the aileron torque rods.

can someone tell me what are these for? correct me if I am wrong but in my opinion when cutting into the root and drilling the dia holes for wing fixing this must weaken the this area of the wing.

Hi Andrew, I've built a couple of Wot4's.

You're talking about the holes/grooves you need to cut so the torque rods for the ailerons sit flush with the wing? Yes, it does seem as if things are being weakened there but remember that the glass fibre bandage will add loads of strength back so you'll be ok - it's an operation that needs care though.

[Andrew Hill]

ye got ya but I supose the real question is

do I need them when I am installing my servose in the wing 2 one in each wing

so are these rods used if only one servo is used? if you get my meaning

Thanks for the reply Dave

Ah, no - if you're popping a servo in each wing then you'll just need a torque rod connection from each servo to each aileron horn. Then run extended servo leads to the centre of the wing (presubably via small grooves that you'll have to cut into the veneer and foam yourself if using the foam wing) so they are flush with the wing surface and can be plugged into the receiver. The servo torque rods here will be straight wire with a clevis in one threaded end and a right-angle bend or something similar at the other.

From memory the rods for one-sero aileron operation will have been pre-bent at either end. Hope that helps?
