you are correct, the leading edge spar is in three parts, plain tube for the centre and the outers have one furrule each.
Have contacted previous owner who assures me it had no crashes or other abuse, he would say that though.
Lolly has however come to the rescue, I sent her an Email explaining the problem and asking if the spars were the correct ones for higher wind. She confirmed all was correct so maybe a problem with the manufacture of them, she had a shipment coming to the UK so has put in a replacement set at no cost, bless you Lolly and thank you.
On another point and from a previous Blast posting.
The tension in the top bridle is the opposite of my 1.5 SLE's which I think is right but wanted to check.
From the attached my bridle is the same except the 30" on the outside of the "W" is 28" on mine for both sides. Flew with the light weight spar over the weekend and all the tension on the top bridle is on the RED line with the "W" having none to the point it is loose on all 4 lines, the red line is much thicker that the "W" so I think this is fine but as I said, my 1.5 has all tension on the "W" and none on the equivalent of the red.
Crumbs theres a lot of replies, thanks to all. The picture had the spars on the wrong side just to show them, that was all, he said in the blurb they were on the other side when flying. They are the 7/16" spars and are slightly larger outside diameter than my 1.5 SLE's and the wall thickness is 0.03" instead of the 0.02" on the 1.5's, they have the Rev stickers with three feathers which I believe means three wrap. It did come with a set of 1/4" ultra light rods and a set of 1/4" race rods. The pictures are definatley the Rev I received, or its twin brother.
The images are from the original post on the auction site I bought the Blast from, chap said he had bought it a couple of years ago and could not get on with it, was sticking with his EXP, also attached are the pictures of the ferrules and the associated spars. First time attaching images so I hope it works.
