Re: ORLIC
I agree PC board is quite brittle. I've just replaced some broken PC board rudder hinges with 3mm carbon fibre plate, although if I was starting from scratch I would use Robarts. The bit of flex in the plastic is ideal.Jilles wrote:Very neat and skill full.
Is there a reason Robart hinges are not used ? The 3/16"size are very suitable for large scale. I am not a fan of PC board. It does not withstand bending that much and can break like glass.
Another problem with composite plate hinges is that the hole does eventually wear with use. At least if you leave the copper on PC board you can soft-solder a short sleeve of brass tube through the hole to improve wear-resistance. I've done this as a repair and it works a treat. I stole the idea from when we used to make all-moving tailplane bellcranks from the stuff in the 80's and reinforce the join to the pivot tube with a fillet of solder.
Sorry - straying off topic. Loving the build Geoff.
Re: ORLIC
I am now doing a bit more on the ORLIC , making a plug for the canopy.
I'm doing the red and white American one.
The plug is constructed with 3x2 timber with the grain vertical for strength , then covered in filler, making ready for two pack spray, done by a friend.
