Pan & Tilt setups

I've had a lot of peeps asking how I set up my P&T's, here's a handful of the many...

I use hot glue a lot, but please be aware I do not use the cheap art/hobby hot melt glue gun.
I use Bosch hot glue gun and genuine Bosch hot glue sticks.
Bosch hot glue not only is hotter, but it literally adheres better and is very resilient to hot summer sun.
The quality is night and day.

The Hitec servos are modded to rotate 180 degrees.
The difference in quality between the Henge type 260 degree servos is very obvious in the goggles, the cheap Henge servo steps with slow head tracker movements, where-as the Hitec servos are very smooth, no matter how slow the tracker movement registered.

I needed something that was as sturdy a set up as possible while ground pounding. I bought the pan setup from ServoCity. Works very well.

fwiw use a fibreglassing consolidating roller, like the one in the attached pic, an ally/alloy, they make life so much easier and you can roll out the excess resin with ease so not only will the end result be lighter, but it will actually be stronger
Weight WILL increase very quickly if too much resin is used, f'glass does get heavy if you aren't conscious of the fact
that said, this SSS can actually do with a bit more weight up fwd

i'm certainly not about to try and tell anyone how to suck eggs lol but here's a quick basic way to epoxy fibreglass, pretty much the same principal for repairing a boat...
~first give the epo foam you wish to f'glass a light sanding. this is important for two reasons... most epo finishes these days have a smooth wax like finish- epoxy wont stick to that at all, and you do want it to stick, you dont want the foam structure underneath to be able to move around so unless you are wrapping the foam but rather just repairing a spot, Polix is correct, it will peel off eventually. Also it will help the resin bind to the foam by having a mechanical key with the resultant scratching from the sanding. Sand until all the shine has been removed.
~then, preferably with the lightest epoxy fibreglassing cloth you can get, cut out the cloth to exact size patches for the work you wish to do, and when they are all cut out, number them with a marking pen so you know which order & where they need to be applied to the airframe
One layer will protect the...Continue Reading
