New Hobby – New Weblog

My Cycling Adventuers Mast Head

I started another hobby, Cycling.  It’s a natural here in the Tucson area as cycling is a major activity.  Lot’s of road paths and desert trails are right out side the front door, so to speak, and mountain trails are about an hour away.

Take a look at my new blog if you’re interested:  “My Cycling Adventures“.

I still fly in the mornings on the weekends and mix in cycling afterwards.


Morgan RC Battery Cartridge

I went ahead and ordered and received the Morgan RC E-Flite Carbon-Z Cub Battery Cartridge.  There’s a risk ordering optional goodies for a plane because you’re not really sure if the plane will still be in one piece before you get the chance to use it!  Well, I took the chance because I see the immediate benefits it provides for this plane and it’s not just bling.

Small parts come packed in a zip-lock baggy.  No instructions are provided and you’ll need to supply a small bolt and lock-nut for the lock mechanism.  You’ll need to refer to the company’s website to  watch an assembly video to make sure you get it right. Thin CA is all that’s needed.  The video mentions that others have used wood glue and even epoxy but CA will do the job nice and easy.


Note that the two wrench pieces differ from the assembly video and are actually the cartridge front and rear pieces.  The two holes are positioned at the bottom when installed. You use one of the holes for the cartridge gate.


All of the laser cuts are crisp and clean.


I used a 4-40 3/8 socket head screw with a washer and Nylok nut for the cartridge gate.


Assembly took about 15 minutes following along with the video.  Everything aligned perfectly straight.


Remove the existing mount and reuse the screws.  Installing the rack deck was easy as the mounting screw holes were perfectly aligned with the stock mounting holes.


Now you have a one-handed operation to install and remove your flight battery without damaging the hatch opening and the hassle of dealing with the two Velcro straps in a confined space.  In addition, the extra long rack deck allows you to move the battery much further aft to shift some weight towards the tail which you couldn’t do with the stock mount.

All in all an excellent product.





I did it again!  I really enjoy the Carbon-Z Cub and I like everything about it.  The Carbon-Z Splendor offers a different flying style and uses the same batteries as the Cub.  Assembly log coming soon.

Needed to Complete

– 6S 22.2V 3200mAh 30C LiPo flight battery
– Charger capable of charging 6S LiPo batteries


What you need: A Watt Meter and Power Analyzer that measures peak Amps and Watts like: a Watt’s Up or Turnigy

watts up

After logging the various measurements you can use these simple calculations to estimate your planes performance and to make sure that you are within the limits or your ESC and motor. Very helpful when experimenting with different prop sizes to find the right performance you’re looking for.

Let’s use these two examples of peak Amps and Watts taken with my Watts Up on my Carbon-Z Cub:

Peak Amps at full throttle = 56

Peak Watts at full throttle = 1,333

With just these two numbers we can determine expected length of flight time, watts per pound and the equivalent internal combustion engine horse power.


To determine the expected length of flight time, you’ll need the peak amps at a set throttle position and the battery capacity in milliamps:

The calculation is: Battery capacity in mAh divided by amps x 60

The result is: Flight time at full throttle = ~3.54 minutes

Of course you may not fly at full throttle the entire flight so take several readings at various throttle positions to help determine an average.


You can determine the expected flight performance based on the peak watts and the weight of your plane:

The calculation is: Watts divided by plane weight

The result is: Watts per pound = 157

Use these Watts Per Pound values to help determine if you have the power to match your needs:

  • 50-70 – Minimum level of power. Think Park flyers.
  • 70-90 – Trainers and slow flying scale planes
  • 90-110 – Sport / aerobatic and fast flying scale planes
  • 110-130 – Advanced aerobatic and high-speed planes
  • 130-150 – 3D and ducted fan planes
  • 150-200+ – Unlimited performance 3D and aerobatic and larger ducted fan planes

Bear in mind these are industry related  de facto numbers and I find that in the real world they are not all that reliable.  Use them as a starting reference point.


You can also estimate your electric motor performance compared to an internal combustion engine

The calculation is: Watts divided by 746

The result is: IC equivalent = 1.8HP

I ‘ve been looking at the new E-flite Carbon-Z Cub since it came out late last year.  I was looking for something  electric to have some fun with and this one really fit the bill, with the added bonus of being float ready. So I finally got one.  Look for a build (assembly) log soon.

Key Features

  • Easy-to-complete final assembly
  • Quique Somenzini design
  • Exceptionally strong, easy to repair, Carbon-Z® construction
  • 5-channel control including functional flaps
  • E-flite 60-Amp Pro Switch-Mode BEC Brushless ESC included
  • Digital servo control including operational flaps installed
  • Pre-hinged control surfaces with control links installed
  • Plug-in wings and stabilizers
  • High-grade socket-head hardware use throughout
  • Hatch covers provide easy access and a wide range of battery options
  • Included 3 meter sailplane aerotow mechanism requires just a single servo—sold separately
  • The optional camera mount (EFL1045023) is ideal for aerial photographers—sold separately
  • Floatplane ready when used with the Carbon-Z Cub Float Set (EFL1045016)—sold separately



The E-flite® Carbon-Z® Cub aircraft is the first to offer patented Carbon-Z strength and rigidity in a giant-scale package. Like the full-scale Cub Crafters Carbon Cub SS airplane, this ultra-lightweight model by World Aerobatic Champion Quique Somenzini is astonishingly versatile whether your intention is to cruise gracefully or surprise scale admirers with envelope busting aerobatics. Its Carbon-Z structure has been molded with all the detail you’d expect from a traditional model, but you get the popular benefit of weight savings plus maintenance ease. Despite the size, this giant-scale model disassembles quickly into compact parts you can transport in almost any vehicle.

Based on a platform known for its legendary versatility, the Carbon-Z Cub makes giant scale so simple—now even more RC pilots can go big. Its enormous Tundra wheels tackle just about any terrain you choose to romp from, or you can easily mount the optional Carbon-Z Cub Float Set so no RC adventure boundaries stand in your way. A mechanism is included for towing sailplanes with wingspans as large as 3-meters and there’s even an optional camera mount so you can take one-of-a-kind images from a bird’s eye view. Even if you get carried away, the Carbon-Z structure is easy to repair.

A major part of what makes this giant scale icon so versatile is the control innovation package included as standard equipment such as the digital, metal-gear servos, and slop-free ball-link hardware. Because the included flaps are functional, greater control at low airspeeds is possible in addition to the ability to significantly shorten takeoff and landing distances.

Although this aircraft may look tame, its brushless power system has been specially chosen to offer incredible muscle to take full advantage of its multi-purpose potential. But if the ultimate Carbon-Z Cub experience is what you’re after, then you’ll want to install the extraordinary Spektrum™ AR635 6-channel AS3X® Sport DSMX® receiver (sold separately). An all in one unit, its AS3X System will allow you to experience agility beyond the immensely popular Cub form, deliver enhanced stability and a feeling of control that’s always crisp and natural. The 6-channel aircraft transmitter you choose should at least have adjustable dual rates and expo. For your convenience, the power system and battery compartment can accommodate a wide range of 6S Li-Po configurations.

It’s been a while since my last post or update.  I’ve recently moved and had all of my stuff in storage for 6 months.  I’m just now getting the hobby room setup and hope to be back to building and flying by summer.
