You are technically accurate. A Tiger moth (or any Gipsy powered tractor plane) does have the prop spinning clockwise view from the front! Not many model planes, even super scale ones, actually do!
Unless your prop adaptor and nut have left hand treads make sure your prop nut is done up tight otherwise it will fairly easily spin off in flight!

Aye, it has done before! You'll see earlier in this thread where I had wires running through the holes in the motor tying the prop on... Then I realised I was using the wrong washers in the prop mount and I just tighten with grips and it's all good now. 😋

To elaborate on the landing gear issue - should anyone have suggestions for resolving it - the struts are too flexy, in that they will give with ease, but cannot spring back until the weight is lifted off them. This allows a bump to knock one wheel outwards, and that wheel will stay there until lift off, causing the plane's aerodynamic profile to be off-set from the wheel base.

I am wondering if I simply made one that didn't have the loops bent into it, then used wire rather than string (string is very easily stretched beyond its elastic limit), then I would have the needed balance of ductility and stiffness. The loops were supposed to prevent the gear from being bent out of shape but they appear to be encouraging that.


May be you could check out the full size landing gear the WW1 planes used.
They had rigid under carriage but the travel was supplied by binding the underslung axle to the struts with bungee elastic. For your model elastic bands may do. I have not tried this method myself, just an idea🙂

I think you mean over slung axle rather than under slung!

Your quite right Simon, I got my over and under mixed up. Over🙂
