Tom Flynn 1 Posted March 4, 2018 Share Posted March 4, 2018 For some time now I have been playing with idea of building an Xtra Wot. I've Flown most of Chris,s models and not found a bad one. Anyway I have seen a few on eBay and other sites, but don't really want a plane that has been hammered by other flyers. So I thought I'd see who had the best price for this model on line. To my surprise It appears that this kit has been discontinued, so no stock about. I haven't seen this mentioned anywhere so I thought I'd ask on here as, I'm sure some body has the story. Thanks Tom Quote Link to comment Share on other sites More sharing options...
Paul Marsh Posted March 4, 2018 Share Posted March 4, 2018 There might be one for sale at a swap meet, either new in box, unbuilt, or well new built model, Failing that, if you want an Xtra Wot, what about the ARTF version. It is quite good, and only around £200, where the kit was over £250. I have one and they fly well. Incidentally, I have 2 kit ones and a ARTF one. The model one is the first kits made and over 20 years old now. No 1: first Xtra Wot, built. Engine OS 120fs Pump Mk1 No. 2 bought from a Swapmeet. Has an OS 120 AX ARTF version Saito 182 Flat Twin.

Brian Cooper Posted March 5, 2018 Share Posted March 5, 2018 If you get one (Xtra-Wot) reinforce the tailplane. . This an area which is known to be weak on this model and it can and will collapse whilst being pushed hard with some spirited flying. B.C..

Rocker Posted March 5, 2018 Share Posted March 5, 2018 Just realised the XtraWot is a different model from the Acro Wot XL .The Xtra Wot is the Chris Foss Model that you have to build and the Acro Wot is Ripmax ARTF Quote Link to comment Share on other sites More sharing options...

Lone_Wolf Posted March 5, 2018 Share Posted March 5, 2018 Take a look at the Chris Foss website (contact us section) where it says: "All our kits, with the exception of the Xtra WOT, are available throughout the UK via leading hobby shops and from selected distributors overseas." You can buy the Xtra Wot directly from Chris I believe. Quote Link to comment Share on other sites More sharing options...
Gary Binnie Posted March 5, 2018 Share Posted March 5, 2018 SMC often have one in stock, being very close to Chris. I got my XtraWot from there. Virtually finished, recently painted with two pack paint that is not fuelproof, back to the drawing board!! Gary Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted March 5, 2018 Share Posted March 5, 2018 The Xtra WOT is a great machine and looks much better (especially with 2 person larger canopy) than the XL WOT. But, is it still made as I heard that it has been discontinued? Quote Link to comment Share on other sites More sharing options...
Jon Laughton Posted March 5, 2018 Share Posted March 5, 2018 I think you have to order it direct from Chris Foss models via their website? Quote Link to comment Share on other sites More sharing options...
Engine Doctor Posted March 5, 2018 Share Posted March 5, 2018 Extra wot is a great flyer and a very durable model . The weak fuselage just in front of the tail plane on early kits was I believe modified some years back . Violent snap rolls could snap the fuz especially with a very powerful engine fitted. I built and flew mine on a YS 140 , a great combination. Smashed it after a couple of years and gave it to a club mate who quickly rebuilt it and its still doing the rounds and flying more sedately with a Enya 90 FS up front.

Tom Flynn 1 Posted March 8, 2018 Author Share Posted March 8, 2018 Well I thought I would follow the website's advise and ring. Well that's a challenge on its own. Rung about 8 times, left message,s but still no contact, No email address, and the last time I saw a fax machine I was still at work.

Tom Flynn 1 Posted July 1, 2018 Author Share Posted July 1, 2018 Hi All, well I have my xtra wot, a used model in need of a bit of TLC. So I have a couple of questions to carry on with this. Do I need 2 servo,s on the elevator, and what inboard battery should I use. I have an SC 120 to fit up front. Cheers Quote Link to comment Share on other sites More sharing options...
edgar Posted July 1, 2018 Share Posted July 1, 2018 Mine flew fine with one servo and a snake on elevator, my battery was a 2000 mAn Eneloop. This was with a Saito 180. It might be even better (more responsive and agile etc.) with two servos, but my understanding it was designed for five standard servos.

onetenor Posted July 2, 2018 Share Posted July 2, 2018 Edgar why should two servos on the eles make any difference if both are linked? Quote Link to comment Share on other sites More sharing options...
edgar Posted July 2, 2018 Share Posted July 2, 2018 I don't know, it might not. Even if it is, I'm not a sufficiently skilled pilot to be able to notice small differences. I have been told by an owner of a similar sized model, with two servos on elevator, that this is better on large models, but I've never tried it. So this is merely hearsay as far as I am concerned, but I know at least one person will not agree. I thought I could avoid the discussion by saying it "might" be better. I can speculate (just for the fun of it): it's a big elevator (compared to my other models), there is noticeable flexibility between the two halves (on my example) and, having seen this, I have considered that this theory (two better than one) might have a small benefit. However one is good enough for me, I prefer simplicity. Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted July 2, 2018 Share Posted July 2, 2018 Two basic reasons come to mind for twin servos - redundancy and reduced servo load. If one servo fails you still have a degree of control from the other one. You can get away with smaller, lower spec servos which are usually cheaper. There is one other reason applicable to either poor builders or perfectionists (delete as applicable), if you have an elevator joiner there's the possibility of joining the two halves asquint. You can avoid this with two pushrods from one servo but this can give unbalanced movement because of the link geometry but two servos on separate channels allow you to adjust the throws and introduce curves if need be resulting in perfectly matched elevator movement on each side.

Tom Flynn 1 Posted July 2, 2018 Author Share Posted July 2, 2018 Well you have all been great with your advice. Just to put you in the picture I’ve stripped this plane down and I’m slowly rebuilding to ( I hope) a better condition. Looking at the many pictures on line and you tube, it appears this is an early version of the kit. Here in Weston S Mare although the sun is beating down, we have had a continuous strong wind, since the sun came out, which, to me, makes flying not the fun event I enjoy. So I have had time to play in the garage. Taking the rudder and elevator off, I’ve found very large hinges epoxied in place, which don’t lend to being pulled out, so I’ve made new from stock wood. I was going to use Mylar hinges pinned in place as per normal, when I put back in situ. Any comments on that. I’m still to address the wings, but the aeralon are now out and the hinges are also rather large items also well and Truly stuck in. So thoughts and advice please.

Martin Harris - Moderator Posted July 2, 2018 Share Posted July 2, 2018 3 options spring to mind: 1) If there's enough aileron movement to allow access, slide a scalpel blade down the side of the hinges to cut the glue line and extract the old hinges. 2) Cut them off and re-hinge alongside. 3) First part of option 2 followed by option 1 Quote Link to comment Share on other sites More sharing options...
