Default RE: KATANA XL - new release

Fenton - Good work getting the 160!

If it were me, I'd use a Mejzlik 19X8 and an NMP muffler or a slimline...oh and 30% Magnum seems the best fuel...this is the setup that Nath (3D Dancer) uses....simply awesome!
Ask him for any more info

The factory in China are incredibly rigorous. They have told us that if we can test something for at LEAST 200 flights with no probs (e.g a spring-loaded hatch latch was suggested, in preference to the two retaining bolts), then they will use it. All prototypes and production samples are flown for 200 flights as proof of concept.

We have suggested to the factory that the U/C is a weaker design (than say a hunk of ally), but they said it is better to have the legs break rather then do worse, more lasting, internal damage to the fus structure/woodwork...They have no personal experience of legs breaking.

Some time we will be trying solid carbon rod for the U/C legs (have to do some thinking on the axles, but shouldn't be a problem...Nath is a machine-meister!).
If this proves to be a good solution then it will be submitted to the factory.

So far, all our legs have been fine, as far as I'm aware.

Regarding positioning of the throttle servos, the user is left to do it themselves, due to the huge choice of engines (and hence different throttle positions) available. YS, OS, Petrol, (even leccy) all have different throtle positions!

Finally, the YS is a REAL bone-shaker but our Kats have held up fine so far...
as with ANY ARTF I would always suggest going around joints with cyno, just in case.
