Hi gang,

I came across the Nexus Legato during a post-flight catalogue browse last
night, set me wondering whether it is practical to convert my standard Nex
to four stroke?

Does anyone have the part numbers for what is required?  I realise that the
Legato uses the VR flapping head, but I assume that it will fly on the
standard Nex head, mine already has various VR parts, including pitch
slider, swash plate, washout, etc. What else would need to be changed - is
it just engine mount, gears & fan? Is anyone out there flying one and what
is it like?

This is very hard to type as I keep having to dash outside, a Robinson R22
is making very low circuits over our house. An hour ago I was flying my Nex
and had a Hughes 500 fly over very low, even though I was flying in the
centre of town!

Cheers,

David,
Just keep the 32.

Hi David,

The general consensus I've heard from Legato owners is that it is not worth
your time.  The OS52 4-stroke has about the same Maximum power as the
OS32SX.  However, being a 4-stroke, it has more power and torque in the low
to mid-range and less at high RPMs.

Unless you are extremely familiar with 4-stroke engines and really love
them, I would recommend not doing this conversion.  The price Kyosho asks
for the conversion is horribly expensive.  You are correct in your
assumption that the substantial difference is the engine mount, pinion gear
and fan.  The flapping head part comes from the fact that the Legato kit was
built on the Nexus Deluxe.

If you're looking for power, then the OS46 conversion is a better approach.
However, this is not without issues as the 46FX is really too powerful for
the 30-size Nexus, so you might need to do some tricks like installing a
longer tail boom and larger main blades.  If you want something with more
zip than the Nexus, I would recommend looking into the Concept 32VR.  Even
with the OS32 engine, the VR is quite a bit faster and more maneuverable.
It also shares a large amount of common parts with the Nexus, so it is a
logical upgrade path.

Leif

Harlan,

Probably the best advice! Thanks!

Hi Leif,

Thanks for the info., I wasn't expecting the 4 stroke to produce more power,
just to be different and quieter! I have had quite a few 4 stroke engines in
planks (in a previous incarnation :) ) and enjoyed the way they ran.

My Nex already has quite a few parts from the VR, basically because I
destroyed my VR a few weeks ago in a dramatic backwards inverted crash! I
have a new VR built and waiting for the gyro to return from its medical
examination at CSM!

The VR certainly has more zip, too much, in that it kept making do silly
things (see above!) but it was so much fun that the replacement was ordered
as soon as the first was determined to be beyond economic repair.

If the conversion kit is so expensive, then I doubt that I'll bother.

Thanks again,

So...since the VR and the Nexus seem to have so much in common, what is it
about the VR that gives it so much more zip than a Nexus?

Just wondering which kit I should be considering next time I make a Nexus
shaped hole in the airfield.
