I bought one Friday. Here's my experience with the install. This is just my personal experience, yours may be different.

First the Head looks really nice, adds alot of bling to the blade. Initial install was smooth and easy.

Test flight, I was very lucky I didn't crash. Would not fly at all with any stability. Full stick didn't even seem to do anything other than make the CPP shoot up in the air uncontrollably. I was very PO'ed but determined.

Rework, took the fly bar weights off (I'm not using any now) and replaced the supplied ball links with the stock ones on the blade. The Microheli ball links are WAY too tight. Holy sticky collective batman. Again lucky I didn't crash. Next problem, grub screws that hold the head to the main shaft. I've seen other post suggesting replacing these. DO IT! Go to your LHS and get a bit and tap and replacement screws. I used 2.5X4 hex head and they worked fine. The Microheli swash (at least the one I have that came with the head) is garbage. The swash broke after two flights. Thank god I have the E-flight blue aluminum swash. It was difficult to get the blade pitch right for tracking, Finlay I swapped the microheli pitch linkage parts with the adjustable ones on the bell hiller head (stock). After at least 6 freaking hours of tweaking the head I Finlay was ready for the final flight.

Final flight. Smooth as a baby's butt. I mean silky smooth. Response is crisp and solid. This is the best my CPP has hovered and flown ever. Hovering took minimal input to hold rock solid. I dint think I've ever had my fingers off the sticks this much. Head looks great IMO ( I installed a high output blue LED pointed at the head and the effect is just great especially in flight)

From mad to glad a noobs story. I'm glad I bought it and stuck with it. In the end this was a good purchase and has made my CPP a better bird.

Sorry about the crappy pic but it gives you an idea of how it looks.

Now that is a great looking blade. I'm glad you got it all sorted. Do your LEDs do anything or just stay lit?

Thanks! The tail blinks. I hope to get some strobes from http://www.tjtrc.com/LiPoV2.html soon. After the head is sorted out it works great.

Buzzkill, good to hear you got that head sorted out. Mine was the same PITA but but now I am quite pleased with its' performance. Got a question for you, or anyone else that has upgraded to a CNC head. What are your plans for the old plastic head? I am looking for a complete plastic rotor head for a scale Colibri, fan tail micro I am working on. BCPP or HoneyBee CP2 (Bell/Hiller type) is what I am looking for. Anybody got one for sale/trade/donate? I tried the classifieds but got no replys. Must to be a bunch of these plastic heads kicking around considering the number of CNC conversions that have been done. Help, please!

I have a complete head minus the pitch linkage rods. Send me a PM.

First crash with CNC head. I fly in my app. parking garage at night. Its heated and lit so it makes for a great practice area. While flying tonight a neighbor pulled into the garage and I slowly moved out of the way (its 300' long so I had a lot of time to move) anyway, when they tried to lock their car they must have hit the alarm button because their car started blowing the horn. Stupid me, startled I looked to see. Bad idea. Its was a reflex reaction but long enough to nail my car with the CF blades. No damage to the car I was almost on the ground. One wasted CF blade, one landing skid and the feathering shaft. No broken grips. No snapped linkage rods or ball joints. Microheli main-shaft is fine. With a hit like that on a plastic head, guaranteed fried grips and probably linkage and shaft. CNC head held up very well. I thought for sure I had just blown $125. This head is a tough little bugger.

I just bought a microheli cnc head and I already assembled it onto my bcpp. The question is that I'm not sure if I should disassemble the preassembled parts and us thread lock or are the preassembled parts already thread locked?

Thanks,

Antoni

As a rule of thumb, yeah, take it apart and thread lock everything that could use it...

Even an ARF kit... :arggg:
