RE: CADET/KADET
G'day
The Kadet range from Sig are my favourite trainers. The Kadet Senior (and its little sister the Seniorita) are my absolute favourites. Both have to be built from a kit. They fly slowly and are extremely stable and forgiving. They do not have ailerons but I think this is an advantage for some learners. The Senior is available as an ARF and it has ailerons. My favourite Kadet Senior is now about 10 years old and is powered by a Saito 62 though for most of its life it had a Saito 56. This is an extremely good combination.
The LT range (25 and 40 of which I have one of each) are great all around trainers. They have ailerons. My 25 has an Enya 36 four stroke and the 40 has another Saito 62.
There is also a version of the Seniorita with ailerons available from Hobbyking as the Margurita. I have one of these too and love it. It has a 25 size electric motor and a 5000mAh battery which gives it about 40 minutes of flying on one charge. It is very cost effective too. It is very similar to your photo.
I see from Sig's site that they have some new ARF models too.
The only Sig Kadet which I do not really like is the old Kadet Mk 2. It is quite heavily constructed and this makes it less easy to fly as it has to fly faster. Any of the others you will love.
