Scruffmeister Posted June 8, 2015 Share Posted June 8, 2015 I have a brand new, un-run OS 81FSa sitting on the shelf. It was intended for a Wot4 at one point before I decided it was too heavy and went a different route for that model. I'd like to do another kit build after I finish my Wot4, but I'm still building up my confidence and have limited time available so I'm looking for something along the lines of Sig kits, Chris Foss etc. rather than a plan pack. The Acrowot seems like a good choice as I know many people like a Saito 82 in it, but the OS 81FSa weighs a good 3.5 Oz more than the Saito so is that just going to be too nose heavy or just heavy on the wing? What would you put it in if you had this engine and my constraints? Edited By Scruffmeister on 08/06/2015 18:59:52 Quote Link to comment Share on other sites More sharing options...
Frank Skilbeck Posted June 8, 2015 Share Posted June 8, 2015 Chris Foss Wots Wot maybe Quote Link to comment Share on other sites More sharing options...
.. Posted June 8, 2015 Share Posted June 8, 2015 My Acrowot has an OS70 fs up front and still needed a bit of ballast so that's an option. But I do think the wots wot would suit it well. Quote Link to comment Share on other sites More sharing options...

Steve Hargreaves - Moderator Posted June 8, 2015 Share Posted June 8, 2015 I'm sure it will be fine in an Acrowot SC...I have an ASP91 4 stroke in mine...no ballast & flies lovely... As an alternative how about one of these......certainly on my "to buy" list....& should go nicely on an 81..... Quote Link to comment Share on other sites More sharing options...
Robin Kearney Posted June 9, 2015 Share Posted June 9, 2015 I had the same motor on the front of my ARTF Acro Wot for a few years, wonderful motor and plenty of power. I still needed 6oz. of lead up front to balance, but with the 81 pulling it along it was not short of power. Quote Link to comment Share on other sites More sharing options...
Engine Doctor Posted June 9, 2015 Share Posted June 9, 2015 Kyosho Majestic , they would be perfect together. Second choice would be the Acro-wot . Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted June 9, 2015 Share Posted June 9, 2015 Sig still do the AstroHog by the look of it, nice vintage style low winger. Quote Link to comment Share on other sites More sharing options...
Concorde Speedbird Posted June 9, 2015 Share Posted June 9, 2015 If you want something a bit different then the Galaxy Domino Biplane is worth having a look at. My Hobby Store do the kits now. I have built one with an SC 80 now and it is a lovely aeroplane with a stunning climb rate. The quality of the kit isn't quite Chris Foss standard but you are a good enough builder to be able to deal with that. I have done a log on here somewhere (search Galaxy Domino Bipe).Wots Wot kit is excellent. My Dad has one. Top wing mounting a bit odd if you want to bolt it, we are going to change it. Acro Wot similar but with one wing. Both excellent based on general consensus. CS Quote Link to comment Share on other sites More sharing options...
Scruffmeister Posted June 9, 2015 Author Share Posted June 9, 2015 Thanks all, loads of great ideas! Just incase I increase in bravery, are there any well refined designs for this engine size for sport aircraft as plans that you would recommend?
