I cut the fuzz into 3 and then removed the inside of the middle layer. Makes the control rod & servo easy to install, but the edges distorted a bit. I don't want to do the same with the Hawk, but I don't have a good idea yet.
Now I have been slowly but surely getting tired of all this manual sanding so out came my trusty Einhell (Dremel look alike). Fitted to this was a DIY router base, the idea coming from, I think, Gert Nieuwoudt.
The working end of the setup.
With the right bit inserted and a sturdy guide it made for a perfectly routered slot for the fibreglass tubes. As the tubes aren't there for structural strength, a couple of dabs of foam safe CA keeps the tubes in place.
All that remained was to add a balsa cap to finish things off.
In my quest for some decently priced servos for the F18 Project I came across these little beauties. They are HD DS929MG ball-bearing metal gear digital servos weighing in at 12.5 gram from Heli Direct, supplied by Sandy Sutherland from XHeli @ R188 a piece + postage. Not bad compared to the close on R300 most hobby shops want for the plastic geared HS85. Unfortunately he only had three in stock, so I opted for two for the ailerons.
I'll probably end up with standard servos for the elevator as space is no problem inside the fuselage. Here they are shown sandwiched between a HS85MG and a HS55. It is the same width and thickness of the HS55 and only about 2mm higher. The 2.2kg.cm torque should be ample for the application. Time will tell if they withstand the Volksies Test....
