RE: Beginner kit...no experience
G'day
It really depends on what sort of things you have already done, how old you are, how much you want to spend, how big your car is etc etc.
The Sig kits are really good to build. There are several versions of the Kadet ranging from quite small to quite large. Some need some woodworking skills, the others less so.
So ... if you are under 40, then I'd suggest one of the LT series. There is the LT-25, which only needs a small engine as it is quite light but it is still a good size model. It will fly with a 25 two stroke and really well with a 30 four stroke. The LT 40 is a larger version of the LT-25 and will fly really well with a 40 two stroke or a 45 plus four stroke. Both use sheet sided fuselages which are easy to assemble and their wings have flat bottoms so they build flat on the plan which makes things easier. Both fly really well and I currently have one of each thought the 25 is in retirement.
If you are over 40, then I'd suggest the Kadet Senior or its smaller sister the Seniorita. They are essentially the same plane - the Seniorita is simply a scaled down Senior. A Seniorita will fly with quite small engines. I used to fly mine with a 15 size diesel though originally it had a 30 four stoke. A 25 two stroke will also be fine. The Senior needs a 40 or larger two stroke and a 45 or larger four stroke. I currently have four Seniors with the following engines. Saito 56 (great), Laser 70 4c (amazing), Saito 90R3 radial (total overkill), Saito 72 (almost as much overkill). I modified the one with the Saito 72 to add ailerons with less dihedral (the angle between the wing halves). I recently sold my Seniorita to a friend who needed a model urgently.
There is also the Kadet Mk II but I have never had one and can't comment.
Have fun choosing and building.
