|So why the modifications?|
The following video was my 2nd flight with this plane, I attached the 11 gram camera in a rough position and off I went.
Mid-flight I suddenly lost elevator control (pitch up/down) later discovering the control line had totally come off!
I figured the bolts for the control horn collar must of worked lose and the entire line between servo and elevator came off. The first upgrade worth mentioning is fitting locking nuts (those with a rubber grommet inside) on all control horns.
|First is re-enforcing the nose area of the fuselage which after my elevator accident left a twist. I'm using the 10MM carbon fibre strip which is 16CM long (6 inches) just above the fibre glass rod which runs down the entire fuselage. Notice the marked line (one on each side).||Here's a mock fitting to ensure the cut is deep enough. You can also see where I have moved the battery pack back by cutting out the rear indented block and glued it up front, harriers are much easier now.||I applied CA to both sides of the carbon fibre strip and VERY quickly inserted it into position, while it was still wet I quickly by eye pushed the fuselage back straight until it dried. Repeat the process on the opposite site, the nose area is now solid and has no play.||The last small yet important modification is adding a 15MM piece of 2MM wide carbon fibre strip on the rudder bottom. This is where it contacts the ground and will wear down very quickly if you try tarmac / other hard surface take-off or landings, let this little strip take the scrapes and when its worn simply replace it!|
