Product Review: Fullymax LiPo
Hardcase & Saddle Pack Batteries
LiPo batteries have become the battery of choice
when it comes to powering the flight pack only. In
the main they work very well, specifically the 2s 7.4V
packs are perfect for most voltage regulators. However, with me especially and maybe at times you I
suspect, sometimes these batteries just don’t suit,
fit and so are a real pain in the proverbial.
Recently I came across several 7.4V LiPo battery types meant for R/C model cars. Initially I wasn’t
really interested in them, but I did have a moment of
inspiration. At that time I had a hassle trying to fit
both a flight pack and power pack into the model helicopter I was working on. I could fit one battery, but
not the other, and it was really bugging me.
The inspiration came in the form of orientation
possibilities. The battery that I found would best use
the space available was a “saddle pack”. The battery comes in 2 halves, hence the saddle reference.
The beauty is that the 2 halves give you more options on how to fit this battery pack. It only took me
a couple of trial fits to find the perfect installation.
All these batteries also have a hard case, designed to withstand the rigours of RC model car
abuse. I then realised that this would also be useful
to have on a model helicopter, especially when these
are high capacity packs, with a “C” rating, more than
enough for any power hungry flight pack. The hard
case also could be more securely held down, plus it
would be more likely to survive a severe crash.
By thinking ‘out of the square’, I found a use for
batteries normally associated with RC model cars.
Fullymax batteries as reviewed were:
• Fullymax 4900mAh 2S 7.4V 25C hard case
• Fullymax 3300mAh 2S 7.4V 40C hard case
• Fullymax 5100mAh 2S 7.4V 30C saddle pack
Highly recommended. Check them out at Concept Hobbies in person or via their web site.
Product Review: Spin Blades
I’ve reviewed these excellent main and tail,
rotor blades not too long ago. The 2 rotor system
blades have performed flawlessly, both for flybar
and flybarless systems.
Recently the distributors for Spin Blades, Concept Hobbies, imported a line of rotor blades
specifically designed for multi-rotor heads. With
the availability of multi-rotor heads for scale use,
having access to the right blades is paramount.
Spin Blades offer blades to suit 3, 4 or 5 multirotor heads. Lengths start at 325mm and go up to
840mm. Colour can be either matt black or white.
Spin Blades have put their logo right at the blade
root for aesthetic appeal. With the matt blacks, the
logo is virtually invisible as it’s black on black.
The airfoil section chosen by Spin Blades is
asymmetrical. The reasoning is that inverted flight
wouldn’t be required, the lifting section would enable
heavier loads to be lifted, and possibly the rotor RPM
can be reduced to enhance overall scale effect.
To check out these multi-rotor system blades, I
selected the 3, 4 and 5 blade types in 600mm length.
There are any number of 600 sized scale model helicopters on offer from just about every manufacturer,
so this size would probably be the most popular.
The physical characteristics are:
The weight errors I found would be easily compensated by the tracking tape used on these blades.
I really liked the fact that they look scale, i.e. long,
thin and flexible enough to show some droop.
I haven’t been able to fly these blades myself
as I don’t have a suitable scale model helicopter
available, yet. However a good mate of mine will
be using these blades on his 600 sized Hughes
500E, with 5 blade head. Once the model is ready
to fly, I’ll let you know just how well they go.
Nevertheless, knowing the excellent pedigree of
Spin Blades, I can recommend them, no worries.
Check them out at Concept Hobbies
personally, or via the web.
