I liked the Sig Somethin Extra for a second plane. This is an easy build or in an ARF. You can set the controls to do whatever you want. Very nice!

I just saw a Sig 4* 40 "arf" at Sheldon's Hobbies.

My second plane was a Sig 4*60 with a super tigre 75 on the front. Totaled first one from not extending my antenna but had an exact clone built because I liked it so much. Was able to use everything out of first one except plane.

Good Luck,

Mike

My best second plane was a Goldberg Tiger 60 with a Saito 91 four stroke. This was a easy landing airplane and also had a lot of vertical and I really enjoyed it till the radio went south-----

I had a "south bound" radio myself, cost my my glider tow plane...
Hate those loose solder joints.

Have you considered a Sig Astro hog? This is a tough, great flying bird. It lands and flys like a trainer if you wish or can be cranked up to do about any trick you wish. I know 3 people who
had this as a 2nd plane and learned a great deal with it.
Thanks,

How about a SIG Rascal 40 high wing.

For low wing a 4*60 or a Great Planes Space Walker. They are easy to fly and Aerobatic.
