RE: Black Magic v2 builder's thread! *Updated*
Critical Update: Gear block
Ok, this one is bugging me. I flew my own V2 well over 1000 flights before the infamous regulator failure, with no noticable wear and tear on the gear block. I DID tear mine out at Tangerine last December, but after seeing what I hit turning off the runway, it didn't strike me as an issue.
This year after seeing all of the Black Magics belonging to others, it's easier to count the ones that have NOT torn out the gear block. I believe that's evidence enough to classify this one as a weakness that needs to be addressed.
The VF3s already incorporated more structure for this, and are being updated to tie into the gear block and D1 doubler as a slotted fit.
I don't have a V2 to demonstrate, but what needs to be done is make a small half former at the rear of the gear plate, tying into the D1 doubler. This does not have to be large, ony about 1/4" tall at the middle, flaring up the sides to about an inch tall at the sides. Also it may be a good idea to make a triangular gusset piece at the front further anchoring the front of the gear plate to F2. This is critical if you plan to fly off grass.
I will try to make adrawing later to make it clear.
