Nick Williams Posted June 19, 2021 Share Posted June 19, 2021 Hi all, I have just picked up a Chris Foss Acro Wot kit and can’t wait to get started on it! Whilst not new to flying I am new to kit builds so I’m reaching out to anyone that has been in my shoes for tips and advice on building, also any essential tools etc I should get hold of. My plan is to build it up with a Saito 82b some decent servos and wheel spats to finish. thanks for reading ? Quote Link to comment Share on other sites More sharing options...
ken anderson. Posted June 20, 2021 Share Posted June 20, 2021 hello nick, the A/Wot is now an olde world kit and over engineered. The model is pretty robust and well designed to last.i've owned two and on each one i reinforced the area inside the fuz,around the undercarriage mount with a fibreglass bandage to give it a bit extra strength(i fly off grass)fuel proof the entire tank bay inside before you add the top deck...and enjoy the model...oh and trace all the parts before you start the build onto a bit of old wall paper in case you need to do a re build..... ☠️ ken anderson...ne...1...A/Wot dept. 1 Quote Link to comment Share on other sites More sharing options...
Engine Doctor Posted June 20, 2021 Share Posted June 20, 2021 (edited) When you make up the fuz sides make sure you make a left and right hand sides, easy to make two left or two right sides?. Also for the Saito set the firewall back as per instructions for fourstrokes. Fit a servo for each aileron instead of single Central servo as some early kits had. Everything else is simple. Great easy flying model, enjoy. Edited June 20, 2021 by Engine Doctor 1 Quote Link to comment Share on other sites More sharing options...
Nick Williams Posted June 20, 2021 Author Share Posted June 20, 2021 Thank you guys, all points noted ? I must say I am looking forward to building this. I’ll post some progress pictures as I go if I remember. Quote Link to comment Share on other sites More sharing options...
Low pass Pete Posted June 21, 2021 Share Posted June 21, 2021 (edited) Hello Nick I reworked my old Acrowot over the winter. Now in the air and has become my goto model for now. They do fly very well. I have stuck with a single central servo for ailerons which is just fine although I do prefer to use two. I used car spray paint for the Fus and Oracover for wings etc. Suggest you use a Dubro fuel tank as they can be set up to have a double clunk which makes defuel at the end of a flying session very simple. I always use 3 colours for fuel pipes. Clear for feed to carb. red for pressure feed and green for refuel/defuel. Ref instructions in original kit ref side thrust I did not follow for the rebuild and I put engine on with no side thrust and that seems fine with my selected engine(OS55 2 Stroke). My original build was with an OS70 4 stroke and it always needed rudder to correct a vertical climb. Not so now. Anyway have fun on your build.

Cuban8 Posted June 21, 2021 Share Posted June 21, 2021 (edited) Nice model and not a fully glass fuz as I first thought - just the cowl ? Edited June 21, 2021 by Cuban8 Quote Link to comment Share on other sites More sharing options...
GrumpyGnome Posted June 21, 2021 Share Posted June 21, 2021 I think the new kits come with cutouts for dual aileron servos..... a much better solution imho. Every AcroWot I have ever seen flies really well ....... with a Saito 82, should be really good. Quote Link to comment Share on other sites More sharing options...
Redex Posted June 21, 2021 Share Posted June 21, 2021 My kit came with cutouts for dual aileron servos - in which I have installed HS-225MG servos. Quote Link to comment Share on other sites More sharing options...
Nick Williams Posted June 21, 2021 Author Share Posted June 21, 2021 Hi all, This is the later release kit I believe that comes with the GRP cowl and undercarriage and duel aileron servo recesses pre cut. I am guessing I will be ok with standard sized servo’s? I would also like to add some wheel spats and possibly a CF under carriage and tail wheel if anyone has any recommendations? I am just waiting for some tooling to arrive and then I can get the on with the build. ⛏?? Quote Link to comment Share on other sites More sharing options...
GrumpyGnome Posted June 21, 2021 Share Posted June 21, 2021 (edited) Cf undercarriage, yes, good idea, especially with the Saito. I personally wouldn't bother with spats as they can be a right pain! GG P.S. the plane in my avatar no longer has them ? Edited June 21, 2021 by GrumpyGnome Quote Link to comment Share on other sites More sharing options...
Cuban8 Posted June 21, 2021 Share Posted June 21, 2021 (edited) Spats can really improve the look of a model, and in my experience providing you don't fly from a patch with a surface no better than a bomb site then most types other than very small ones can be made robust enough to survive. With an aluminium undercarriage of reasonable size, several self tapping screws that fix into a well glassed in and substantial piece of ply within the wheel well will usually be rugged enough to do the job. Wire undercarts can be a problem, as saddle clamps or similar will tend to be not so durable. Having said that my 22 years old Goldberg Chippy still wears its spats with the internal reinforcement despite my rough landings on occasion! Most kit and ARTF spats have mountings that are hopelessly weak as standard, so it's not surprising that they fall to bits.

Andy Stephenson Posted June 21, 2021 Share Posted June 21, 2021 I fitted spats to a 28% Extra thinking they would be big enough to cope with a well maintained sports field but they accumulated so much in the way of grass cuttings I had to take them off as they were binding up the wheels. I've amassed a box full of unused spats from all the ARTFs I have built over the years as they are always impractical on the strips I fly from. There's also a problem with tipping a model with spats on it's nose, it either skews or breaks them. Quote Link to comment Share on other sites More sharing options...

I’ve ordered this, I think it comes in ever so slightly narrower than the GRP one supplied, I’ll compare them once it arrives ? Quote Link to comment Share on other sites More sharing options...

Picked up an original Acrowot kit from a deceased member. Must be an original kit, vaccine cowl etc. But missing instructions. I could manage to build it, but not sure of : cg, movements, engine thrust rec etc. Somebody help please ??.

Keith Berriman Posted June 27, 2021 Share Posted June 27, 2021 (edited) Just out of interest I have thought in the past of fitting two midi servos in the wing centre section to give finite control if needed On fitting a 4 stroke does the firewall need to set back some ??

ken anderson. Posted June 27, 2021 Share Posted June 27, 2021 hello keith ,i would go down the 2 servo route,and yes the firewall can go back a bit for a four stroke,its in the instructions.... ken anderson...ne..1..firewall dept. Quote Link to comment Share on other sites More sharing options...

Hey Keith, also note update bulletin 1, point A which meantions re enforcing the fuselage sides. I’m not sure if others have done this but I’m planning on adding the additional 1/32 ply. Point B is also worth doing, u/c re enforcement ? Quote Link to comment Share on other sites More sharing options...
Keith Berriman Posted June 27, 2021 Share Posted June 27, 2021 Hi Nick Definitely glass cloth the inside the fuselage area where the undercarriage fits My experience with glass fiber undercarriage is on the occasional heavy landing it starts to create splitting inside the curve and this then gets worse and eventually time for a new one The ally one can be straightened out Quote Link to comment Share on other sites More sharing options...
