Enlarging servo bay in foam wing

[Chris V]

My fantastic Tangent Glider has arrived from Germany this weekend

The wings are quite a thin section to say the least, the servo wells are already machined in. A quick measure has indicated that a 8mm thick wing servo
would just go in and I mean just go in. With regard to 8mm thick servos Hitec do make one at a nice price and I need 4

There is a vast choice of 10mm thick servos from lots of manufacturer's

So i could do with removing 2mm of the foam from the bottom of the servo wells any ideas on the best way to do this ???

I thought about using my soldering iron and thought about making wire cutter out of coper wire wrapped around the soldering iron tip

I don't really want to start hacking it out with a knife as I am concerned about the overall thickness of the wing

Any ideas would be appreciated

What a brilliant idea !! I think that will do the trick

If the wing is this thin you will end up with no foam above the servo anyway so I would remove it all and put in a patch of carbon to support the "roof".
After the hot wire you can remove any residue by Using cotton buds soaked in thinners (carefully). Finally you can take a sanding block with a square piece of wood. Put your servo plate in whilst the epoxy is still wet.
