How to make MPX Twinstar II Brushless Motor Mounts

[Shikra]

Good info mate.

For the real lazy ones out there...

Replace the stock motors with one of these and an APC 6*4e

Direct screw in replacement.

Not quite so efficient as outrunner with abig prop, but still very good flight times. 

Also a nice drop in for EZstar too!

Hi Shikra, thanks!

I thought it was my civic duty to make this little vid in response to...
RC Day: Multiplex Twin Star II Maiden Flight

Those 2200's are the sh!t I must say. I'm too much of a chicken docile flyer to put twice as many steroids in my plane :)

[Shikra]

LOL - I'm a steady flyer too... thats what throttle stick is for!!

Love the Twinstar. Just realised something ...
After a few attempts to fly gliders I taught myself to fly properly with the original Twinstar when the first came out. Got to be  14-15 years ago now.
Then taught myself FPV on a TS2 about 5 years ago

You've been around the block with these then.

Hairless Hippy reckons the TwinStar is being pulled, what a pity. I've just bought a mint 2nd hand one off a BMFA chap for £50 all in. That should keep me in spares! I had better maiden this thing now, or no one will ever believe a word I say again - hope the frikkin mounts hold :)

An ultra-simple modification is to remake the motor mounting plate but extend it down at least 3mm in order to lower the motor, thus giving enough clearance to the ribs on the motor bracket for an outrunner. I made mine out of 1.5mm glassfibre plate. I'll try and dig out some photos which explain it better.
You can also buy aluminium plates which do the same thing. They are advertised as being machined but are really just drilled castings.

Electrotor, that sounds like a bit more work. Here I have used only the stock goods, nothing added. Job time 15 - 20 mins for both.

It's just the front plate that I remake from a flat piece of glassfibre pcb. No modifications are necessary for the Multiplex motor mount which you glue into the nacelle in the normal way as you would for the brushed motors. Also I am using motors which do not require a radial type mount which you have used and modified. The motors are mounted directly onto the rear face of the plate. Using my template I could cut several in 20 minutes. A photo will explain better so I'll post one later.

I suck.

It's not a competition Flyboysee, it's about sharing ideas.  :)
On my first Twinstar I used radial mounts, reversed the Multiplex plastic motor mount, spent bloody ages filing off the ribs to clear the motor casing and it worked really well. Then I saw the aluminium plates and thought I could do that easily and cheaply, hence the fibreglass plate. As the meerkats say, "simples."
Here's the pictures.

That's a good, quick solution! Nice.

I have a pair of these in mine running 8x4's with one reverse pitch to counteract thrust. It was so fast i had to adjust the epa on the throttle to bring it down. I tried using the original mounts but both were ripped apart on the 2nd flight!! had to land with one motor hanging out of the wing. Remade witht eh fibreglass fronts as above and all ok now.
