Andy Blackburn Posted July 11, 2009 Share Posted July 11, 2009 I bough a Kyosho Osmose 70 last year and I have to say it's possibly the nicest ARTF that I've ever flown. There are a few minor niggles but they really are minor; 1. The covering is multi-layered and wasn't stuck down properly. I had to go over it with an iron (NOT a heat gun) and then stick all the overlaps down with Solarfilm Prymol. 2. The fuselage appeared to be twisted very slightly so that one of the wing seats had to be adjusted to get the wing dead square with the fin and stabiliser. In-flight handling with standard digital servos and a Spektrum Rx is very, very good. The undercarriage seems to be fine, although the spats have been junked and the 2" wheels replaced with 2.75". Power is an O.S. FL 70 which is only just enough on 10% nitro, ideally it should have something like a Saito 82. Getting the balance point far enough back with a non-pumped engine set-up is a bit of an issue, I had to install the battery (1500 mAh) at the wing trailing edge above the servos. Overall - expensive, but worth it. Never though I'd say that about an ARTF . Quote Link to comment Share on other sites More sharing options...
Bruce Richards Posted July 11, 2009 Share Posted July 11, 2009 I have recently bought an Osmose 2nd hand with a Saito 82a and the fuel tank set at the C of G. It has the same servos as yours and a 5 cell Rx pack. Cost £250 and is in great condition. Bargain I thought. The previous owner had about 50g of lead on the tail. I have removed this for now. I will fly for a while before I add it back if required. Flys very well as you say. Quote Link to comment Share on other sites More sharing options...
Bruce Richards Posted July 11, 2009 Share Posted July 11, 2009 Yes the spats are rubbish. They are so thin and are clamped to the U/C over such a small area. When I gat mine they had already had a hard life so I removed them and reenforced them with more class cloth and resin plus larger steel washers. They have been fine so far 5-6 flights.

ntsmith Posted August 12, 2009 Share Posted August 12, 2009 The spats, as so often is the case, can be strengthed by fibreglassing a piece of the ply - use marine ply and not lite-ply and fibreglass resing not epoxy - to the inside of each spat. This adds an enormous amount of strength. Quote Link to comment Share on other sites More sharing options...
ntsmith Posted August 13, 2009 Share Posted August 13, 2009 Has anyone had issues with the covering and has anyone tried their suggestion of spraying with clear polyurothane? Quote Link to comment Share on other sites More sharing options...
