Mugin 3M v III

The new design of the Mugin UAV 3M is out.

It's a huge UAV platform with 300 mm wingspan. The platform caters to larger UAS projects such as universities or commercial projects. It's really not a beginner platform.


The platform is available here: Mugin UAV 3m vIII

It comes with or without engine/prop.






Twin Motor


Type: Two-stroke piston valve petrol aircraft engine
Displacement: 55cc(27.2ccx2)
Bore x Stroke: 34mm×30mm
Carburettor: Walbro(Diaphragm & Butterfly Valve)
Max. Output: 5.6ps/7600rpm
RPM Range: 1600-7800rpm
Weight: About 1780g(Engine+muffler+CDI)
Ignition power: Auto advanced CDI(DC 4.8 Volts , 4 cell NiCad or NiMh battery)
Fuel mixture(Ratio of gasoline and oil): 25-40 : 1
Propeller: 20X12-23X8 two-blade prop( suggest to use 22x8 prop)

  • Colton,

    I have built a number of aircraft from this manufacturer.

    Do not take the parts that are supplied as a guide as to how to assemble the aircraft.

    You must depend on your own capability in building a large RC aircraft. By all means use some of the hardware supplied, but source your own where it doesn't fit the bill. If you are at all in doubt, get some assistance from the RC aircraft fraternity.

  • Can anyone give me guidance on how to install the control horns? Do they expect you to just thread the plastic pieces with the bolts? That's how it seems right now, but i'd much rather use bolts on the other side, but can't find any confirmation...

  • Have you ever flown model rockets, they have a really small charge of gunpowder which pushes the Shute out. You prob want 4
  • fuselage = fiberglass

    wing = wood

  • @cessna, payload bay have 65x22cm

    height -  you can use +- 22cm

  • So, not all motors can be reversed. Interesting.

    Ours was supplied from Desert Aircraft already reversed.


  • Hello Jack, i reversed my DLE too bu when i contacted DLE team it say that DLE

    connecting rod are not made to work reverse and that i have trouble in the future so i ordered 10 reverse props.
  • Interesting photos in your blog Eduardo.

    I am just a weekend hack pilot, and I could only land our Muginn (version 1) on our 120 metre mat when all the ducks lined up, and the engine kept running well enough to do a long high alpha approach. I was just not used to such a large airframe and my perspective was way off.  The biggest difficulty was in estimating the speed on the landing approach. It landed in 40 metres in this picture of the first landing because one of the main wheels had fallen off. I had more success later on when Tridge would read out the landig airspeed to me.

    I like the carbon fibre? booms. This means you will not require such a heavy weight to balance the aircraft, and lighter landings mean less damage.

    It appears you have the same main undercarriage, mounted in the same way.  The problem is that the  mounting bolts are very close together, and the mechanical advantage of the long undercarriage in a not-the-best landing will damage the bottom longerons. I hope you place a strip of at least 50mm long, 4mm thick aluminium under those nuts.

    The structure in the nose supporting the nosewheel to me looks like it really needs some beefing up. Hmm - let it break and be easy to repair, or make it strong and have it really tear things apart in a bad landing? We broke out a 12mm plywood bulkhead a few times, but it did have a 4Kg lead acid battery behind it.

    We used standard direction propellers that were easy to find. The direction of the motor rotation was reversed just by re-setting the timing.

    I am really looking forward to hearing how you get on.

  • Yes, are you absolutely right, Giovanni.
    Impossible to compare Penguin B and Mugin (any version). Swan-02, I never see before, in fact.
    My thoughts about Mugin V3, are concerning converting for EP.

    Btw, I've talked with Fabio at mundogeo connect 2013. Very good plane / systems do you are building, congrats!

    @Jerome ,

    I purchased quite a few props of various config/size from hobbyking. 3 blade  pusher are little difficult to find but they are available there.

    I have seen sullivan generators used in smaller airframe but am not aware of its performance. It was little bulky.

    but there is one more choice called Jewel  onboard generators which is converted brushless  moto.  check that out.  I am trying to home brew this and looking for info on what modification is needed to make brushless motor/generator.
