It's an easy build and flies great on a ball bearing .46. Two suggestions- 1-do install the tail wire supports, they dont weigh much and if you plan on putting this plane through violent maneuvers like I do, they are a must 2-the fuel tank is very hard to install/remove/maintain once the fuselage is built, a hatch on the top or bottom of the fuel tank compartment makes things go a lot smoother. custom making this piece now will save you time later, trust me.
hope this helps
PS-Ive been flying mine for quite some time with a rubber band and zip tie back-up on the wings,no problems to date, probably due to the lack of lateral force on the wing halves during flight
