Airfix 1/72 Sea King / Revell Roxter fusion


Recommended Posts

I found these in Argos 2 for £15

And they have some good parts...90mah lipo, 2 motors and an IR system

So I fixed it with a previously started sea king. 

 

It was only a test build to test the concept so a rushed (very bad) paint job.  I hate the gloss yellow as well..... so hard to use. 

 

But it works...

The module of course needed resoldering and rejigging with addition of longer wires and a transistor to allow tall light to flash. 

 

The tail rotor I used a 4x8mm motor instead (taken from old mobile phone - the vibrating motor) and needs putty to reshape the tail but allows a tail rotor action.  

 

The IR receiver is in the cockpit and sits neatly in the cockpit panel. 

 

Thankfully only a test build as now I know the mistakes eg poor placement of switch and charger

The switch is under the white rails so hard to use and the USB charge position is awkward.

 

Will go for the easier colours of the other airfix sea king next time. At £7.50 each for those revell helicopters they are a cheap source of gadgetry!

The cat must find that fascinating.  😄

 

Does it fly or are the R/C copter innards just to animate the display?

Just for animation and scaring cats. Way too heavy to fly!

Neat bit of repurposing! How did you get the tail rotor to work? Enquiring minds want to know!

Mobile phones have really tiny motors that they use as a vibrating motor.  The hard bit is removing the weight on the shaft but can be done neatly by crushing with a pair of vice grips. 

 

The actual placement of the motor requires cutting the existing position of where the rotor sits, and placing the motor then rebuilding the 'shape' with either filler or putty. Then all needs to be done is wire down to the main module.  The tail led is placed simply by cutting a space at the top.  Flashing is possible by using a flashing transistor (which also controls the flashing led on the lower surface led).

Very cool.  I'm curious to know if you managed to get it to fly..

Unfortunately not.  Way too heavy!

How did you hide a motor in the tail rotor?

 

Very small motor 4x8mm. You have to essentially carve out plastic to fit motor and remould (with putty) the original shape

There were a few questions around tail rotor. I've started another sea king so here's what I've done with tail rotor

I've used milliput to build the shape after aralditing the motor in place. 

 

Will of course sand down when ready.
