indeed NC, the incident with my smaller plane was a good wake up call so i'll constantly have that in the back of my mind on the next run with the Siren, attached a picture of the covering job i did after fixing the dent., (don't mind the washing i chucked on the bed) and yes it is actually lever arch label stickers, so basically a paper sticker with clear tape i added over that afterwards to seal the paper from water should a drop or two fall on it, not ideal covering but it worked,

Flew mine in 15 - 20 mph winds a few days ago. Man, is that fun. Especially when the rest of the flyers are siting on the sidelines complaining about the wind. A few months ago, I flew it in even stronger winds and had a blast.
Don't let the wind turn you off when it comes to this plane.

For sure

There's a vid somewhere of someone slope-soaring one of these things.

Plus the wind is your friend for take-offs and landings.

A good headwind helps to slow it down a bit and cruise-on in on landings - provided, of course, you can land into it. I wouldn't want to try to put it down if there's a raging cross wind with those big wings it has...

Hi everyone. Would appreciate some feedback. Recently I became interested in the Kunai. Now I see that it has an even bigger sibling, the Siren. What are the pros and cons of both? Which one would probably be better for an intermediate pilot new to warmliner/hotliners and why?

Jeez - what was the big bird in hot pursuit there? Sea Eagle?

Was the flight moto-off, or did you give it a tickle every now and then - she was certainly shunting along there

You mentioned adding ballast - did you just make it heavier around the CG, or load the nose up a bit?

Mmm, the Siren is more like a cousin to the Kunai than a bigger sibling - the Siren is definitely NOT a bigger version of the Kunai.

The Siren is more toward the "fast glider" end of the spectrum or "warmliner" good for full-throttle speed passes down the runway or fast vertical climb to altitude and some thermaling if there is lift (though the Siren is not solely designed for thermaling like a Calypso or Radian).

The Kunai is much the same thing, but lighter weight, more nimble and a stronger wing also capable of whatever aerobatics you can throw at it.

Either is great for an intermediate pilot, but the Kunai will be quite a bit easier to get setup and airborne as it comes with the motor installed and all that. The Siren requires motor installation, radio installation, and you have to do a little research and ponder which motor/battery/prop for the Siren. With the Kunai, the decision is made for you.

Here's a link to my blog on the Siren. I still have it today and love flying it:

I'd back ordered a Kunai but thinking now I'll go the Siren instead. I have a nice composite 2.2 glider for thermaling but was really chasing something good for windy days and hot dogging around like I use to do with my much missed Blizzard
