Yesterday my twin had its first outing. It is a dream. 53" span using the Oodalally wing, it is powered by two SC .15s.

With this power it climbs like a homesick angel and does everything in the book. Loops, rolls, spins, inverted, outside loops four point rolls and so on.

Stuart Pickett who flies my models for the camera loved it. We both found that we felt completely confident in a few moments of take off..

A long shallow dive, screaming low pass and pull up into a series of very fast rolls really curls your toes

Single engine flying just needs a touch of trim held in and it even can be turned into the dead engine with care. This was found because the other way would have been right through the sun.

Could it be electrified? Well, there isn't much room but I did need lead in the nose and you would need more with electric motors so you could lengthen the nose and modify that.

And the name? well, obviously the model was very loosely inspired by the Grumman TIgercat

Well. What a happy announcement. I was thinking about starting my Oodalally as the next project after the 2014 mass build (Mini Jazz) so I will now make two sets of wings. Thinking about it, why not three then I have spares for both.
I have a pair of OS 20FS engines and wonder if this combination would work. Maybe it would bring that CG a tad further forward albeit with perhaps a slight overall weight penalty. Mr Ashby please note, you have at least one fan here and yes, I will be renewing my subscription.

Yes, it should fly on the FS 20s but rather slower.

The only difference between the wings is that the ribs have to be spread slightly at the location for the nacelles and a couple of tubes installed for the leads from the servos.

If you asked SLEC nicely they would probably cut an extra set of ribs for a reasonable price for the extra wing.

We can always rely on Peter to produce another popular design. In fact I have a couple of OS 15 FSRs lurking in my shed but if I were to build a Tiger Cub when the plan comes out it will probably be Leccy. In fact I would speculate that the majority built will be of the latter category nowadays? What do you think?

I would only build a twin for electric power.

Not many sports twin models in the plan service so its going to be popular.

teeth 2 Not my design! Ask Mr Miller......

Should'n't be too heard though. With the cell packs in the nose, there would be plenty of rrom adft of the motors to fit rear-folding electric units.

Be sure to post some pics, eh?

IT weighs enough without retracts at over 4 1/2 lbs.

If anyone wants to do a conversion drawing they are welcome. Me? I am too busy designing the next two or three models!laugh
