UNLIMITED vertical performance
With 300+g
thrust and a model that weights approx. 160-180g,
you will have 2:1 power/weight ratio
This model
is extremely
quick to build
(it took me about 4 hours - including the design time)
And the materials cost next to
nothing.
You just need some 5mm (or 6mm) Depron, a CD-ROM motor,
a 700 m/Ah 3-cell LiPo pack and some micro RC gear
The wingspan is 520mm
and the prototype weighed only 162g
Power
is from a reworked CD-ROM motor that's been rewound with 11
turns of 0.45mm wire, with a Star connection.
12 x N44 5x5x1 NdFeB magnets replaced the original magnet
ring. Kv = 2530 |
|
This
is Delta number 3. (Depron models don't last forever).
As you can see, the nose is different. Frank Weaver's delta
(see pic at bottom of page) looked so much better than my
original, that I decided to give my new one the same look.
The motor has now been rewound with 11 turns, 2 x 0.35mm
wire. It runs sweeter and feels more powerful, probably due
to more copper on the stator. |
|
Static thrust is
300+g on 3 x
700mA/h Etec LiPo's
All of this was built at home, including the motor conversion
An
inside view of the motor reveals the magnets that were cyanoed
in. I used a short length of alu tubing for a spacer to better
lign up the magnets with the stator when the motor is
assembled. |
|
The
Gunther prop has a push-on fit. A short length of Golden Rod
outer is pressed into the hole and some heatshring tubing on
the shaft. Then wet the tubing and press the prop on. |

Frank
Weaver from Vancouver Island, Canada sent in pictures of his
version, which he calls "Demon Delta". |
|
A
side view of the "Demon Delta" shows the stealthy
look of the canopy. |
