Martyn's Ballerina @ 115%

It's called Ballerina 115 - sounds more impressive than Ballerina 70

Simon, try a coat of satin finish varnish or satin Flair Spectrum/Spectra clear on the pilot, it really does transform an iffy pilot with a gloss paint job as I've proved several times. nowt wrong with Dick's finish that a coat of satin won't sort out.

I maidened my Ballerina 115 this afternoon. 3 great flights. Still a little nose heavy and the first flight was a little under elevated. What amazed me was how agile this aeroplane is. Clearly not a precision Aerobat but on the first flight I was looping rolling split S reverse Cuban stall turns with no problem at all. The only thing that I couldn't get right was a spin which always ended up as a spiral. Hopefully pushing the CG back will fix that.

I am am using a 13x7 APCon the OS70 - which made the landing speed a bit on the high side but it was very manageable.

The troublesome engine performed faultlessly on Contest 10 which was a bit of a relief

still a bit of trimming to do but it's a lovely fun aeroplane to fly.

Well done Peter

Martyn

Congratulations Martyn. Sounds like you really enjoyed it! yes

It looks a dream to fly and from all accounts it is! I put mine off today in favour of running the engine in and pre maiden checks hoping the wind was less tomorrow and at the latest forecast it look like it will be and straight down the strip too!

And the maiden - only a short snip

 
From just after take off, you can see that it was a touch under elevated after the initial climb out

Hi Ian

andy was suffering from cold hands so no more videos.

Landings were all ok (if a little fast), quite smooth and where intended but all nosed over due to the rough ground. The strip is unusable as the grass is far too long and the ground too soft to be mowed.

Great fun though.

I am glad I built it slightly larger. My eyesight started playing up during the 3rd flight so it was time to call it a day.

Well, I'm quietly jealous really. No chance of me building one this year.

That makes three Ballerina maidens this weekend! My wheels are raked forwards in line with the leading edge of the wing so I didn't really have too many problems getting away, or down.
