A great flyer if you build light, no bad stall, slow flight and harrier possible, glide slope reasonable for a biplane - build it heavy and you will have a dog.
Engine - OS 50 SX - with 12x6 APC prop - excellent engine
Good to fly, looks good and sounds good with Bison muffler
I have always liked the look of the Edge so I had to buy this high quality ARF kit-
It is good to fly and limited by the pilot only - has the glide slope of a brick without the engine but that is its only minus
Engine OS 91 FX Two Stroke ringed with 16x6 APC prop
Another Chinese built ARF, similar to the 40 sized but has removable wings - this kit was put together in one night with radio, servos and engine the next night. As usual I decided to put a larger than recommended engine on the airframe. The manual recommended a .70 4 stroke or .60 2 stroke. Looking at the power and weight I decided on an OS 91 FX 2 stroke (the same weight as the OS 60) and used a 16x4 APC prop - I changed the landing gear and wheels shown on the first photographs - too weak by far. Again the flight characteristics are excellent and limited only by the person moving the sticks.

Probably my favorite aircraft for pure fun flying - does what you want it to when you want it - the pilot is the limit on this aircraft
Chinese built ARF aircraft, just glue the wings and tail to the body and its done - I used a slightly larger engine than the recommended .46 size and decided on using a TigerShark 0.56 ringed two stroke (donated by a previous crash) with a 12x4 Master Airscrew K series Prop - A very good powerful set up for funfly - Just make sure than you give enough time to run in a TigerShark ringed engine, I had used my .56 in a sportster type model for a good 20 -30 flights
