Great job on the guide, very informative. Is the stock mini cp pinion the same as a mod .5 1.5mm bore homefly 8t pinion? Also at what voltage should one stop flying? Lastly, do you think you could take a close up of where the C05 bolts in to the frame as well as any mods needed to get it in properly?

Thanks,
Ben

Thanks Ben,

Here is a picture I edited for you. The other picture is from my mCPX review.
The Genius CP and Mini CP will use the mCPX mounting holes (with the blue arrows) in my picture.
The only mod you may need to do is to lengthen the motor mount holes on the frame a little bit.
This will depend on what size pinion you use and if you use the Mini CP
or Genius CP main gear. The stock brush main motor screws work great for the C05 motor.
If you use the motor and esc plugs then it is a simple plug and play upgrade.
I use connectors because I test many motors and pinions for my reviews.

The stock Mini CP motor pinion is 1mm.

Different people stop flying at different voltages. I don't go lower than 3.6V.
Some people don't go that low and some people go even lower.

Great job !

Cracking review as always.

Always enjoy reading them and love the bullet points, etc.:popcorn:

Wonderful review. How about you add flight times with the genius motor too? with genius main and with mini maingear.

#9 Tom Z Mar 19, 2012 01:29 PM

Thanks guys for the compliments. :D

I have now added Turnigy Nano-tech 300mAh 35C battery flight times
in the brushless section. I had to make an adapter to use these batteries
on the MCP. I posted a couple pictures of the adapter.
I'll add head speed also soon with the Nano-tech battery.


mescalinedream, I would like to know that also. I wanted to test the GCP motor
on the MCP but I took off the pinion on the GCP to use on my C05 motor when I made the GCP brushless last year.

Below are some mods many people believe should be done to the Mini CP as soon as possible:
  • Servo Saver mod - Bytemuncher's RCG Blog has detailed info. HeHenri posted how to make a DIY Wire Spring Tensioner for the Servo Saver Mod. And Indoorheli has reported not fully tightening the Main Shaft Collar Screw also prevents stripping Servo Gears.

  • RX Saver Mod - Attach a somewhat stiff support from bottom of Battery Tray so it extends inside the bottom of the Canopy and helps keep the Canopy from easily sliding upwards when it is hit from the bottom. Marioinc posted details. I think if this mod (or any other mod that keeps the bottom of the Canopy from easily pivoting upward) is performed, then there might not be a need to do the RX Coil Saver mod.

  • Canopy Saver Mod - Apply a strip of tape along the entire bottom edge of the Canopy. The Canopy is very durable; however, it easily splits starting from the bottom edge, and then over time the split travels towards the nose. Hopefully taping the entire bottom edge of the Canopy will prevent splits from starting.

  • RX Coil Saver mod - Apply adhesive (Hot Glue, X2 White Gorilla Glue, CA, etc.) to Coil at front lower right corner of RX board, so Coil doesn't break when Canopy is taken off (in a crash?). If the Coil lead(s) has broken from the PWB and the lead(s) is too short to re-solder to the PWB, it can be carefully unwound as required (one of the Coil's leads easily unwinds one loop at a time from the outside inwards; however the other lead has its end exposed but immediately get buried under all the windings - if that lead is too short, probably the other lead will need to be completely unwound, so the coil can be rewound with long enough leads at each end), rewind as necessary (depending on which Coil wire lead broke from PWB), and re-solder as required. I think the Coil can be replaced for about $0.35 + $2.80 shipping from DigiKey.com; however, we should get one and verify it works before publicizing the Part Number.

  • RX Antenna end - Keep it as vertical as possible - this will keep its exposed bare tip from electrically shorting against the Motor or RX circuitry, and have the Antenna positioned for best signal reception. Some people feel safer insulating (Liquid Electrical Tape, X2 White Gorilla Glue, Hot Glue, Heatshrink, etc.) the exposed wire at the tip of Antenna.


After the Servo Holder's - Canopy Holder Rod breaks from a strong crash, Hot Glue a 38 mm (1.5 inch) length of 1 mm CF Rod centered across the back of the Servo Holder above the Servo Holder Guide Pin and Screw Head. If at a later time the Servo Holder needs to be removed, the Hot Glue and Canopy Holder Rod can be removed as required.

Tried to tell people the 300mah 35c Nanotechs rock for this heli but they just said "no no no they suck!"

You, Tom Z, have validated my point =)

Wish the 350mah 65-130c nanos would fit, 10mm too wide and 14g though =(

#12 scub Mar 19, 2012 11:00 PM

4 minutes down to 3.7v with a c05 using 300mah nano-tech batteries isn't that impressive. is that aggressive 3D or sport flying?.. 30 seconds more compared to the hyperion 240.. my hyperion are still going strong even after 80 cycles.

#13 RawmadeCF Mar 19, 2012 11:53 PM

They are $1.82, compared to the Hyp 240 at what, $5+? More performance and flight time at a third of the price is pretty good in my book.
I never said its the best lipo on the market, but that the performance to ratio is fantastic.

#14 scub Mar 20, 2012 04:28 AM

actually they're $4 ;)
i just haven't seen any long term feedback on the nano-tech. im not bashing them as i actually bought 6 950mah for my v120. i just hope they last a bit, even if i get 50~ cycles.. im just amazed how the hyperion are performing as good if not better than when they were new after 80 cycles. i did buy some zippy 350mah that will fit the mini and they're only 8.7g. good reviews from what i read. still waiting for them to arrive.

discount link since i just bought them
http://www.hobbyking.com/buddy.asp?c...9-EAD017E759C3

got a C05M on the way, hoping to get at least 5 minutes sport flying. i haven't come across any other brushless that provide better flight time with decent performance. it's strange because my v120 gets 6 minutes sport flying with stock motor and stock battery :eek: mini/genius brushless setups seem to drain battery.

#15 RawmadeCF Mar 20, 2012 04:46 AM

Yeah I bought 8 of the Zippy 350s too, waiting for them. They just arrived/left NY customs a couple days ago.
