I recently bought a World Models Super Tai Ji 40ep. I wanted a pattern plane that was a little bigger then my 47" Osiris, But Smaller then My 62" Osiris.
The Super Tai Ji fit the bill, wingspan of 52" and AUW of 3lbs 12 1/2 ozs. I am still using the same size 4s 2650mAh lipo that I'm using in the 47" Osiris. I'm able to get 5 min flights and that's enough to practice the Advanced AMA Sequence.
I love my 62" & 47" Osiris Pattern Planes and I can't say enough good things about them, But I think that there's room for one more love in my hanger and the Super Tai Ji will fill that space nicely.
I only managed to put 9 flights on the Super Tai Ji before the weather forced me to hang it up for awhile, But we usually have some decent weather in Dec. Here's Hoping, As I would like to get the Tai Ji 40 a little more dialed in for Pattern work.
I would recommend this Airframe to anyone looking for a plane about the size of the Sequence. It was a easy build, and I used all of the hardware that came with the ARF. Everything fit and the covering on mine was almost perfect, maybe one or two small wrinkles, but not bad enough for me to get the covering Iron out.
