I just installed the Xtreme motor - only have about 20 minutes on it. The first 10 minutes were stock; the heli really "jumped" and it was hard to hold altitude 'til I got used to the extra power.
For the other flights the heli was loaded down with a #16 camera, heavy rubber band, a penny and the custom "see through" canopy. It still flew strong, no problem with the extra weight, and it was very stable and predictable in the air. I give the motor a "10".

Another cool mod! Now I need the Klingon stealth body with secret squirrel spy camera--and the DIY tail stabilizer. You guys are busting through with great stuff!

New & improved stealth canopy...

...taking advantage of the wide angle lens on the #16 cam. You can just see the left side of the canopy fluttering in the breeze...

I guess it's to late because I installed them, but do you use the same stock screws to attach RKH metal upgrades? Still use the carbon main shaft. Holes were not big enough in the Rkh Parts and used the screws to tap it biger. Thanks WS

Hi, Very Nice mod, I think I will try the same, Only use RHK tail boom clamp and attach the elect. connnectors to it. Thanks for posting your idea. WS

You can also use a Dubro U-shaped landing gear strap....


I used one of these first but eliminated the two strews and strap to help with CG.
A few options all for the same purpose... stiffen the tail boom.

Solid CF Main Rotor Shaft

Well I decided to make my own Solid CF Main Rotor Shaft, and I learned a lot in the process. I had to blue-print the stock and aftermarket parts and as I assumed, I found what I believe is a problem with the Microheli Aluminum Main Shaft, the holes are too big!

Ever notice when you assemble a Microheli CNC Anti-Rotation Collar (MHE120SR002A) with the Aluminum Main Shaft (MHE120SR066) the Anti-Rotation Collar has rotational play in it? Then we wonder where the TBE came from!

The holes in the Blade/HH Carbon Fiber Main Shaft (BLH3107) are 0.055” Dia. Corresponding to a #54 drill. Based on the screws used this is correct for 50% thread engagement which is correct for materials which may be easily split like CF.

It looks like Microheli blue printed Blade/HH’s part exactly without correcting for hole size with the different material. In soft metal like aluminum you use 75% thread engagement which corresponds to a smaller hole, 0.052” Dia. #55 drill.

It is possible that Microheli tried the smaller hole and found it too hard to install the screw; I don’t know I haven’t tried it myself, but the screw should go in fine.

So what does all this crap really mean? To eliminate TBE, stick with the Blade/HH Carbon Fiber Main Shaft (BLH3107)!

As for my own Solid CF Main Rotor Shaft, No TBE! And it should last the life of the helo although it was a pain in the butt to manufacture.

alum shaft

I also ran into some problems with the alum shafts, they are .0015 - .002 smaller in dia than the CF shaft. After installing the alum shaft I kept breaking the plastics parts attatched to it. Many broke without any type of crashing. That is when I looked more carefully into the fit of the plastic pcs to the alum shaft. If you are upgrading all your parts to alum then you might be OK, but mixing the alum shafts with the plastic parts will cause the plastic to break more readily due to the extra play. Also more slop in the bearings as they are designed for a larger dia shaft. I went back to the CF shaft and have not broken any plastic parts even after crashing. If you find your CF shaft splits/cracks, it can be repaired.... drop some CA glue into the hollow center then carefully spread open the crack to allow the CA to enter. Close the crack, mabey even add some more CA glue and let it dry overnite. Lightly sand the OD till the plastic just fits (snuggly) re-drill the holes for the screws and your ready to go. My repaired shafts fly perfectly.
Good Flyin

I see you're in Sheboygan - man I've got to get up there soon to Il Ritrovo, I LOVE their pizza and it's the only place I know of to get guanciale (Italian cured pork cheeks)
Hope you were out flying today, we may not see 40F again for a few months!!!
