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.
Flip over and drill the top two holes. (Top two “ALL” position)
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.
I just wanted to share a drilling jig that Jim Stoll made for us Xieda 9958 modders and hacker. I came across his jig on one of the forum. As a hobbiest, he created a drilling jig so he can make new main shaft for the mCPX helis. I guess going CP means more likeliness to break main shafts. Well, soon enough, he was making jigs for friends and forum members.
So I approached him, hoping he can do something similar for us Xieda 9958. That way, we have something that takes the guesswork out of making carbon fiber main shafts for the 9958. The photos below are the result of that collaboration. It’s really a labor of love for Jim and a way to pay it forward. At least that’s the feeling I get from collaborating with him over the holiday break.
The CNC machined aluminum jig will help help you drill your holes at the appropriate locations while keeping the bit straight and perpendicular. The bottom edge serves as a guide as to where to cut. It really simplifies the whole process for those of you who want to experiment with the various heads on your 9958. Switching from a metal main shaft to a CF one shaves about 0.8g. That’s pretty significant.
Here’s a mod to try if you happen to have some broken 9958 blades you want to resurrect. Use MicroHeli mSR aluminum balls. Drill a hole were the ball broke off and screw on one of the MicroHeli ball to resurrect your 9958 blades.
How many of you are breaking off the link guides like I am prone to doing during hard crashes? I put some 9958 canopy grommets on them and hopefully they reduce the breakage rates. Give it a try and let me know if works out for you.
I use tweezers to open up the o ring so they easily slip over the link guides.
Adjust the o ring so they don’t rub against the linkage.
I am searching for the best performing 1s LiPo for the money. Here’s the discharge curve for some of the cells I had on hand. Keep in mind that the Hyperion is brand new. The NanoTech are relatively new as well as the 9958’s stock cells. Only the Turnigy 160 has been well used. I am pleasantly surprise to find they still perform pretty well. It hard to see but the Hyperion 160mAh being new, and also has great chemistry, stayed flat at 3.8v until about 172s. Good performance and I can see why it’s one of the most popular 1s LiPo for the micro helis. I am waiting to get some new ThunderPower 160 to put to the test against the Hyperion 160.
I intend on updating this post with better data as soon as I get new cells from each of the manufacturers to test.
This test is to check discharge to 3.8v. Usually I fly my heli to about 3.7v or so.
Just a quick post showing my previous Xieda 9958 5-in-1 versus the new one I just received.
Some components are moved around and the LED has been moved to the rear. This will allow you to easily see when your 9958 successfully reconnected with your transmitter upon insertion of a battery. Previously, it was hard to tell since the servo does not move and the LED is out of sight inside the canopy.
Let us know if you spot any other changes.
I present to you, a printable template to allow you to create your own custom main shaft for your Xieda 9958. Simply use a PDF viewer to print out the file. Ensure that print scaling is off so the file prints at 100%.
Then simply line up, tape your 3mm carbon fiber shaft to the print out and drill. Using a drill press will help ensure straight holes. If you have a hard time finding perfect, 3mm hollow carbon fiber to use, you can purchase the Blade SR120 tail boom. The one without motor cost about $3.50 at the local hobby shop and should allow you to make 3 shafts.

Anyways, happy modding and stay tune for more exciting things in store that will help you make these shafts practically foolproof.
Here’s the best and simplest method that a friend (Heli Pad of RC Groups) and I came up with to be able to remove the canopy off of Syma s107/s105 type helicopters. I am sure it can be adapted to many others.
The fit is snug and secure. There are no external sign that the helicopter has been modded. So it retains the nice, factory look of the heli.
We do this by securing each canopy screws using a piece of clear plastic. The same plastic that is found on the box the Syma comes in.
Simply ream out a little hole and it fits nice and solid. Keeping both screw nice and tight in the canopy holes.
The end result is the ability to get to easily get to the battery compartment so you can swap out depleted batteries and get your heli back in the air quicker. You can then do the Daryoon’s Plug-n-Play battery mod if you want a really clean look.
Heli Pad inquired about what to do with the nest of wires. Here’s an alternate look in the photo below, showcasing the wires neatly twisted together and tuck away to keep the space nice and tidy.
Anyways, here’s a video demonstrating the original removable canopy idea I came up with, follow by the final, simplified mod Heli Pad and I came up with.
And finally, a link to the RC Groups S107 forum discussion.
