Hello again

Can you give us a rough idea of your ages? My suggestions will vary depending on age.

That said -

You seem to be keen on the Kadet Senior. I can understand that. I like them too. A lot. I do have four at the moment.

So I would be very pleased if my brother bought me a Kadet Senior Kit. You brother should be too and I am sure he will be.

The Magnum 46 will fly the Kadet. It would not be my first choice but it will work fine. I recently set one up for a kid with an old Magnum 46. It flew fine. Not great but quite usable and no serious issues.

Almost any covering will work. Film is light and cheap, cloth is dearer, heavier and lasts longer. Your choice.

The Kadet is an excellent trainer but some teachers hate them. But it is your choice. After all, it is you or your brother that ha
s to fly it not the teacher. You can always buy a second wing kit and build an aileron version later if you want. Initially I would build it as per plan BUT with a little extra strength in the firewall where the front wheel mounts.

When you come to servos etc, almost any standard servo will be ok. Hitec 422 would be my choice.

The real downside of the Kadet is your ability to build it. The stick structure does need to be cut fairly accurately but if you use aliphatic resin (yellow waterbased glue) it will cover a multitude of sins and fill gaps though gaps are best avoided. If you think you can build it, then go for it. Just take your time and measure before cutting. Cut long and sand to size if you are not sure.

The picture shows my quarter scale Cub with one of the Kadet Seniors and a Sig four Star 60. As you can see, the Kadet is a pretty big beast but very light compared to the Cub.
