Ladies and Gentlemen, I'm Jim, very new to the forum and though not a quad newbie, I wonder at times!...I've got a bag full of dusty kites! I've flown so infrequently that my skills are thin! Though I've knocked (or crashed!) the dust off of most of them now in the last month! This forum and the REV forum are super resources...had nothing like this (no kidding) when I bought my first air machine in 94. I have 3 Rev's...two identical 1.5's (bought for stacking) from 95, and a Rev II from about the same time...when I say I wonder about being a newbie...I've flown my Rev's set up incorrectly for 17 years! I just learned about 3 weeks ago that the vertical spars are to be installed on the back side of the sail...hmmm, ok, though I can't hover in all the clock positions, I can hover in most and reading about spar installation it was said that these babies are more stable with them installed correctly...so I'm stoked to see if I really have any skill! Ok, enough blah blah blah... My first question for the collective is regarding the usable wind range for a stock Rev 1.5...I realize that is a two part question when you have to consider line weight...so, lemme rephrase...hypothetically, I've got 300# line, what's the Rev's wind limit? I'd imagine that's spare strength based...on a more advanced line of thinking, frame replacement/augmentation...thoughts and suggestions are invited...I like to stack my 1.5's and wonder if I'm close to over stressing the lead kite... on the softer side of things, I've got 50' 50# line, how light a breeze would you expect a 1.5 to fly reasonably? Thanks!
