Finally got a chance to start putting my Ballistic together. Here are a couple of pictures of what is going on so far. The only thing I need to figure out is to use the CC BEC Pro or the Hyperion 3000mah 2S LiFe to power the electronics. Leaning toward the BEC Pro because it will save me about 4 ounces in weight (not that it will make much difference for my style of flying).

Frame build completed. Needed to do a little work to the rubber servo mounts for the elevator, it was spreading the hexagon bars a little too much for the cap screws to line up with the ends in the frame. A little trimming to the rubber servo mounts and all is good. Frame build was very straight forward with no other issues.

I went a little out of sequence with the build, I installed the swash and levelled it before starting to build the main head block. Made my own swash levelling tool with some plexiglass and small bubble levels.

Did the spindle shaft mod to extend the life of the dampners. It took three layers of shrink tubing to get the diameter right. From those of you that have done this mod it fits snugly into the head block and has just a little bit of rock to it, is this right or should I remove one layer of shrink tubing?

A little hard to see, but here is how it looks with the spindle installed into the main block. It fills the whole area between the spindle shaft and the head block. I am afraid it may be too tight and act like very hard dampers.

I built the swash leveler from some scrap plexiglass. I used a 2" hole saw and a 3 1/2" hole saw to make it. I screwed the plexiglass down to a piece of 2x12 board then cut the 2" hole out of the center. I used the center pilot hole from the 2" to line up the 3 1/2" hole saw and finished cutting out the base for my swash leveler. The bubble levels are from a local home improvement store that I hot glues to the plexiglass. Took maybe 30 minutes to build.

I'm a little concerned the heat shrink method on the cross shaft may be a little too hard for a damper. It thinking it may cause some bouncing on hard stops.

I do like the duct tape method because the duct tape allows some give and rebound when being banged on.

Keep up your rotor speed !

Thanks for the reply Don, I will definitely look for this when tuning and change to duct tape if needed.

I am now 100% satisfied with my Ballistic build and ready to maiden tomorrow if it does not rain. I really enjoyed this build, it is one awesome machine from a design stand point. Everything fit like a glove with no tweaks needed at all to make anything fit. The only things not stock out of the box are the metal main bearing blocks and the carbon fiber tail push rod.

A couple of things I noticed during the build:
I have a Greaser so I pack all bearings in a new kit or when being replaced. The bearings in the Ballistic kit are nicely lubricated from the factory already.
During the torque tube build things were a little tight on the gear mesh. Tore everything back down and did a very detailed inspection and didn't really find anything. There was a lot of forum talk about the plastic inserts in the tail boom. The plastic tail boom inserts looked like they were in all the way but when I placed the boom upright on a flat surface and applied a tiny amount of downward pressure a perceptable click was heard like they were now seated properly. The gear mesh came out perfect upon re-assembly.

Agree it looks great. Just be aware of your power leads touching the frames. You don't want any chafing.
Can't wait to hear how it goes for your maiden flight.

Thanks Fnity. Hey Kevin, good to hear from you again. You can't see it in the pictures, but everywhere a cable crosses the frames has the fuzzy part of the velcro installed to prevent any chafing. The power leads from the BEC Pro and the cable from the ESC are contained in some black spiral wrap so it doesn't show up in the pictures either.

Thats good to know Paul.
The pictures don't clearly show the Velcro or spiral wrap.
Can't wait to hear your first flight report.

dampening
im going to test out that shrink wrap mod, i will let everyone know what its like later today.

-with 3 layers of shrink wrap it is not that snug...well at least with the kind of shrink wrap im using,it should be enough though to stop the dampeners from wearing out as fast though.

also when i was at IRCHA Curtis gave me a little piece of this hard clear rubber tubing to put in the middle of the feathering shaft instead of doing the ductape mod. unfortunately the tubing was too difficult to slip over the cross shaft to do it and i ended up doing the ductape mod instead. it was just an idea that Curtis had that he wanted to try out, i think this will be the best and easiest solution to helping the dampeners last longer because you simply just cut to the length required and slip it over the feathering shaft...then your done

Got a chance to maiden the Ballistic this afternoon in front of the house. Two trim flights and now ready to put some air under this bird and have some fun. If the weather holds hope to do this tomorrow.
