I was asked the following:
Would the holes for BSX match up with holes for V911 main shaft. I plan to get this jig to make main shafts for 9958, V911, Bravo SX from 120SR tail boom.
Well, the jig does a good job of keeping your drill bit straight and true. And if you know what you’re doing, you can definitely use the 9958 jig to drill out holes for other helicopter’s main shaft.
The unique thing about the v911 is that they did a very good job of cloning the Solo Pro. I believe the Solo Pro stock main shaft is a direct bolt on. And because it’s already made of carbon fiber, buying the Solo Pro main shaft and fitting it on the v911 is probably the easiest way to go about it.
For those who like to hack and mod their stuff. Or those who can get hollow 3mm CF tubes, or even those who wants to make their main shaft out of a solid CF rod, then the following photos should help.
I took apart my Solo Pro so I can put it’s main shaft on the jig for comparison. You should be able to use the jig in two steps to fabricate a Solo Pro/v911 main shaft. As you can see, the top two holes of the Solo Pro lines up this way.
That means, from the front…line up the top of your carbon fiber tube to the BSX line. Secure with some tape.
Flip over and drill the top two holes. (Top two “ALL” position)
Once the first two holes are drilled, flip the whole thing back to the front. Remove the tape. And move the CF tube up to line up with the bottom of the word: MSR.
Again, secure with tape. Flip the jig over. Drill the hole, then cut the CF tube using the bottom of the jig as a guideline. Take extra care not to splinter you CF tube.
That’s all there is to it. It’s pretty easy once you do one.
Thank you for the tutorial! I just placed orders for a jig and 120SR tail booms for making frankencopter CF main shafts.
