Up 2 date recommendations for the CZC


Here are my up-to-date recommendations for the CZC:

[ EDIT: some links might be outdated, use google to search. Sorry about that! ]

- Use water-based polycrylic (Glitsa Parketlak PT) to protect the blue and grey paint.

- Put some clear or colored tape over the edges in front of the fuselage / canopy to protect the paint.

- Use 3700/4000 mAh 35/40C lipo's to stay light, easy balance and no need for batery tray.

- Stock ESC has no headroom: Strongly advised to disable ESC's build-in BEC and use a UBEC

- Best to change the EC3 to EC5 or XT90 connectors.

- Tie-wraps or velcro around main landing gear in socket to stop vibration.

- Easy battery tray mod with Velcro:

- Carefully balance the prop - be aware for heavy vibrations !

Stock motor / ESC is fine for normal / scale flying. !! Do not overprop !!
14x8E suggestion with more info:

The stock motor has plenty of power, but overheats when doing more than short bursts. (throws magnets)
When motor fails, or more aggresive / 3D flying is prefered, it's best to do a power upgrade:

Motor: Aerodrive SK3 5055 430kv +/- $50,-
All warehouses:

ESC: Turnigy Plush 100A (80A will do, program card not needed / factory settings) +/- $44,-

(Use a UBEC)

Update: at this point this Hobbywing ESC is a good replacement, scroll down for other option with a build-in 8A/20A Peak BEC.
HobbyWing 80A ESC with 5A BEC: +/- $26,-

Carbon-Z Cub - Power UPGRADE (11 min 16 sec)

Alternative: Optionaly you can use another ESC with a large built-in solid 8A (20A peak) BEC
BG: HobbyWing 80A V5 Brushless ESC Speed Controller With 8A BEC
BG: HobbyWing 80A V4 Brushless ESC Speed Controller With 10A BEC

Other suggested upgrades:

UBEC: TURNIGY (Hobby Wing) 5-7.5A (8~42v) HV UBEC +/- $17,-
All warehouses:


Spinner: Turbo Spinner (63mm) Black +/- $7,-

Prop: Xoar 17x8 +/- $20,-
Alternative: Aeronaut CAMCarbon Power-Prop 16x10 - APC ?

Scale Kavan Tires with profile ° 150 mm KV0266 (2 piece set/pair) (minus 150 grams weight !) +/- $29,-
USA: Order from Sig Mfg +1 641-623-5154 [Edit: not available] [Edit: not available]

Originally Posted by Cubcrazy used to sell Kavan tires, but they no longer list them on their site. A google search revealed this dealer in the US.
(leave air pressure as it comes out of the bag)

(Note: The Dubro wheels are VERY heavy for the CZC, stick to the Kavan's)

Bigger tail wheel, direct fit: 1.75"/44.5mm Ultra Light Rubber Scale Wheel +/- $1,-

Note: for about 170,- / 180,- Dollar you have a fully upgraded top quality flying CZC with better wheels etc.

Solid bolt-on prop adapter set comes standard with SK3 5055 motor - no need to reverse the shaft with this motor.
Note that you need spacers with upgrade motors - About 13mm for SK3 - either between firwall and x-mount, or x-mount and motor.

Note: that the often suggested Power-60 / Talon 90 upgrade is about 3 times more expensive, and less powerfull / efficiŰnt according eCalc.
The Talon 90's size blocks airflow, cut away foam. Setup with PC to remove the need to calibrate every time you connect a battery.
* Real world flight time: up to 2 minutes longer in mixed flight for the SK3 5055 430kv

Alternative BEC:
UBEC: HOBBYWING 10A/20A UBEC-10A (2-6S) +/- $35,- <> $45,-



Alternative spinners:
Spinner: Aeronaut # 725845 Carbon-Optik Spinner (63mm) Black +/- $10,-

Spinner: Extreme Flight RC Elite Electric (63mm) +/- $8,-

Alternative Wheels: smaller KAVAN: 125mm / 5" balloon version (about 46,- Euro a set)

- Optional tow-release servo: E-Flite EFLR7155 (see page 18 in manual)
Alternative: D-MG16 (Digital/metal gear) Weight: 18.8g (needs work to fit)

Total tow line length: beginner 60-75ft. / 20-25m; advanced 90-120ft. / 30-40m

Additional optional upgrades that other people use:

- Optional: Aluminium 2.5" Spinner. Part number: EFLSP250 (Expensive, needs to be modded for most props to fit)
- Optional: Aluminium 2.5" Spinner. TruTurn TTE-2502-B / TTE-0516-140-A / TTS-SCF10150-Kit
- Optional: MM LWC battery cartridge sytem (82 grams extra weight) - No direct postage outside USA, via freight forwarder
- Optional: Articulated Landing Gear. - (Expensive, extra heavy weight, order can take months to arrive)
- Optional: Dubro 150 mm wheels - VERY VERY heavy !! / they don't track as good as Kavan's
- Optional: Scorpion Backup Guard
- Optional: CC BEC

New: Hangar 9 Articulated Landing Gear / 352 gram
Landing Gear Assembly: Carbon Cub 15cc HAN506517
Extra weight compared to stock: about 85 grams when used with the lighter Kavan wheels

Additional used motors info:

- Aerodrive SK3 5055 (430kv) 378 gram 1750 W 16 x 10 - 17 x 8
- * Turnigy G60 (500kv) 360 gram 1500 W 14 x 8 - 16 x 10
- E-Flite Power 60 470Kv 380 gram 1600 W Prop: 15 x 8 - 17 x 7

- Potenza 60 470kv 380 gram Prop: 15 x 8 - 17 x 7 (rebranded Power 60)
- AXI 4120/20 465KV 320 gram 15x8 max 52A
- Hacker A50-14S V3 425KV 345 Gram 16x8 58A / 1276 W (ESC 70A)
- Scorpion SII-4020-420 420kv 288 gram 16x8 56A / 1266 W
- NTM Prop Drive 50-50 580KV 347 gram 2000 W 15 x 8
- Leopard LC5065 430KV 365 gram 1800 W Aeronaut 16x7
- Leopard LC5065 520KV 364 gram 1200 W Aeronaut 15x6
- OMA-5020-490 (490KV) 350 gram 1110 W 15x8 64A
- Suppo 4130/6 430kv 400 gram 1400W 16x8
- Aeolian C5055 400KV 275 gram 1420W 16x10

- Unknow status / untested:

Golden Power A4130-6 430KV 400 gram 1500W (?) prop ??

Scorpion SII-4025-440KV ?? 16x8
Scorpion SII-4025-520KV ??

+/- 80A ESC

All motors need a bit of work to fit: like using the BL-50 X-mount, add washers/spacers etc.
Universal mount:
(stock BL-50 mount needs to be drilled out a bit in most cases)

Stock setup specs:
E-Flite Power 50 BL-50 motor (525 Kv) 364 gram around 1,300-1,350 watts. 15 x 5,5 ( 14 x 8 )
E-Flite 60A ESC (Be aware: little to no headroom. UBEC or a NIHM flightpack suggested)

- * Note that the Turnigy G60 500kv has about the same weight and specs as stock BL-50
Will probably work with a 14 or 15" stock prop and stock 60A E-flite ESC, as it has a bit lower KV.
Always make sure to do a Amp / Watts check with a Watt meter. !

No you can not over prop the stock motor!

Use a 14x8 if you want to use another prop on the original motor.

So stock prop is 15x5.5, I was thinking of trying an APC electric 16x4...?
Thoughts? Anyone do this?

Might be better to change to 14x8

Not sure on 16x4. Use a watt meter and check if your motor runs hot after a short flight.

Over-propping is NOT a good idea with the stock motor.

hello poke. I ordered a CZC lastnight, I have a talon 90 that I want to use with it, I will upgrade the motor to power 60, but with the stock motor can I run a 13x8 3 blade prop? thanks

Hi Pert,

Sorry for my late reply. I have no idea about the 3-blade, but my idea is that it will pull less than the stock 15x5,5 so should be fine.

But you have probably tested it by now

I do wonder how a small 13" performs. The extra blade can make up for it, but larger size I like better for the CZC. Still depends how you want to fly it.

I did the castle, eflite motor upgrade, along with apc props.
I CAN'T no matter how I do it get apc props to balance. I'm using a topflite balancer. I ream the prop hub. Then balance, doesn't matter 15x6 or 16x8 2/3 3/4 throttle is OK after today vibrates LIke mad. I've tried different hub, spinner combinations, stock eflite aluminum 2.5 inch. I've even had other guys in club check my props. Arbors and spinners are running true. I've given up, just using the eflite aluminum spinner and stock prop. I've probable thrown $75 in props talk about being not happy

Strange, I never have read about vibration problems other than the stock motor. So I'm suprised you have that with the Power60.

Suggestions: check on the glue joints on the firewall. Just let some CA go in there, maybe that helps.

Than try a "dynamic balance" - put some marks on your motor / adapter / prop and spinner and set everything at "12 o'clock".. than start adjusting with the prop for starters, turn it 10 to 15 degrees each time and test-run. It can take a long time, but when trying different combinations with every part, there's a good chance you get it to balance.

I hope it sounds a bit clear what I mean, otherwise search google for dynamic balance.

Good luck, I know it's very frustrating

any motor/esc/bec substitutes from Heads Up RC?

Edit: Cross-posting this in the main CZC thread, disregard.

Hi! Thanks for compiling this, I'm grateful and so are a lot of others. While I wait for my CZC to arrive, I want to do pretty much everything you advised, starting with upgrading the motor, ESC, also a UBEC or something else for receiver safety. For the motor, ESC and UBEC you recommend, they are all hobbyking, and I am loyal whenever possible either to my LHS or to Heads Up RC. Could you or anyone recommend any of these motors that would fit the CZC either with or without the recommended universal mount but ideally without otherwise modifying the plane? These are motor candidates that are in stock on Heads Up's site's beefy motor section, any winners?

Emax GT4020/09 470kv, 9.8oz, 60A/1200W for 30s
Emax BL4030/10 400kv, 11.5oz, 55A/1300W for 30s, 181oz thrust w/ a 17x8 at 47A/1120W
Firepower 80 Sport 450kv, 13.3oz, 65A/1400 for 30s
Emax GT4030/08 360kv, 13.4oz, 50A/1250W for 30s
Power Up Sport 430kv, 14.4oz, 70A/1400W for 60s

I'll also need an ESC. The Turnigy Plush 100A's dimensions are 80x31x17mm. Heads Up has this Sky Power 100A ESC - SBEC with similar dimensions, 79x32x13mm. Look good? And the recommended UBEC is the Turnigy 5-7.5A (8~42v) HV UBEC, and Heads Up has this no-name 5 amp and this Castle Creations CC BEC 10A Switching Regulator. Do I want either of those, or should I spring for a Scorpion or a receiver battery? Thanks so much!


PS: Attached, my first draft of "converting" a PA-Cub to the CZC in ClearView RC using Google Images and Youtube videos to extract the motor sound. :)
