Are these planes reliable? They look great. I would like to here from modelers who have one. Which one would love to have a OS 160FX strapped to it?

One of our club members has the 72in Peak Models Yak 54 with an OS 1.20fx. It is a great flying plane with unlimited virtical. An OS 1.60 would likely increase the wing loading too much and detract from it's flight capabilities. So, you will want to go a size larger than the 72in models probably.

I have the SU26M , very nice & quality is very good , I only have three flights up on her so far but looks very Promising.
I used a turnigy 30cc gasser on mine.
Theres a thread on the 3D forum on the SU26.

I <3 my 30% Edge 540T from Peak Model. Great HUGE plane. 88.5", 85", 16lbs RTF with my setup on a DLE-55. 1485 squares makes it near 33% territory for a VERY low wing loading. Vertical is space ship like. lol

How far back did you set the C G? It looks like 6 and a half to three quarter. I have this same plane and have seen awesome hovering pull outs on youtube.

A vid of the first couple of flights of my SU26,really enjoying the plane & starting to try/learn a few new tricks.
Engine is now run in so on a 40-1 mixture & performance has increased a little.
Cheers.
