Geoff S Posted January 21, 2022 Share Posted January 21, 2022 That's what I thought, Peter. There is a drawing error as only one is shown - or at least implied as the wing centre-line goes through the R1. Not a serious problem but it did make me scratch my head for a while, especially as Sarik only supply one rib in the CNC cut set. Thanks for clearing it up.

Peter Miller Posted January 22, 2022 Author Share Posted January 22, 2022 In fact the two R-1s slots form the hole for for the wing dowel that goes into the former. The 1-as closing the sides the hole Quote Link to comment Share on other sites More sharing options...

I for one will be interested in a detailed build of this model, like your Ballerina which was what attracted me to this forum and my subsequent Ballerina build and the rest. Thanks Lucas. Taking this up to 60" will mean the next size motor which will be a 3547 800 kv like this model 4-Max Brushless Motor setup for Peter Miller Little Miss Honky Tonk, RCM&E February 2018 Steve Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted March 4, 2022 Author Share Posted March 4, 2022 Sorry. I didn't realise you wanted to make it larger. I can only say that I had a trying morning at the dentist which made my brain go slow. I will check with the builder as to the size for your enlarged version Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted March 4, 2022 Author Share Posted March 4, 2022 Mick has a Turnigy G45, 60 Watt ESC, 14X7 Prop, 4 cell battery. He originally used a 4248 500 motor but that was not powerful enough. I see that Google shows a Turnigy G46 but not a 45 so maybe they have changed it or Mick got mixed up. I would suggest raking the U/C a bit further forward as Mick's model always noses over on the landing run...Mine never does!! Quote Link to comment Share on other sites More sharing options...

When building starts, most likely October when the days become short and cold, I will for sure make a detailed blog. It makes building much more social.

Lite EFlite has. So it must be a G46. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted March 6, 2022 Author Share Posted March 6, 2022 Note that the plan says 3 hoops for the canopy but in actual fact I used four because I used two at the windscreen canopy join. This was covered in the write up but not corrected on the plan. Quote Link to comment Share on other sites More sharing options...

I would suggest raking the U/C a bit further forward as Mick's model always noses over on the landing run...Mine never does!! I think it's always been a G46. I've had a new 670kv one in stock for a while now, intended for a model yet to be built. I'm using an old Scorpion motor in mine I've taken out of my Multiplex Blizzard as I rarely flew it - partly because I couldn't see it well enough. I actually made a wider hoop for the windscreen/canopy joint on my Chaos, intending to chamfer the front to take the sloping screen but the chamfer ended up merely narrowing the hoop ? Those hoops are the worst part of the build IMO but I guess I'll have to make another - I shed blood whilst cutting one of the numerous ply strips with a scalpel (I found using scissors ended up breaking the wood as it peeled away - probably I'm just clumsy).

Peter Miller Posted March 6, 2022 Author Share Posted March 6, 2022 Yes. I used one standard hoop chamfered to match the windscreen angle and the centre two square and the rear one chamfered. I used a sharp knife and a steel straight edge to cut the strips...No blood!! Actually I have found that models seem to fly better if one has accidentally shed blood on them!!!! (Silly spellchecker doesn't recognise "Chamfered") Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted March 14, 2022 Share Posted March 14, 2022 On of the reasons for the Rans S-9 is that I moved to a club that flies at an airport that is also used by full-size planes. One of these was a Rans S-9, although it was modified enough the authorities designated S-9B. I always scan the drawing to PDF. Since we have an A0 plotter at work I can then print a few copies that can be cut up to serve as templates. If anyone has scanned the RCM&E drawing I would appreciate a copy (on lucas.bm.hofman @ gmail.com). Regards, Lucas Quote Link to comment Share on other sites More sharing options...

I can send you my own plans AND the rcm&e ones Thanks again Peter! I will start with making a material list and order what I do not have. The intention is to start in the autumn, but maybe I cannot wait that long. Any tips for changing sizes and/or materials for a 110%-115% version?

Peter Miller Posted March 15, 2022 Author Share Posted March 15, 2022 For a 115% increase I would not bother to change sizes or materials. After all it is bring the model up to about 60" span and I would use the same size materials for models even a bit over 60" span. Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted March 15, 2022 Share Posted March 15, 2022 @Peter MillerIt looks like you have not used your usual NACA3414 (14%) profile here but a thinner 12% profile. Is that correct and if so, why? Lucas Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted March 15, 2022 Author Share Posted March 15, 2022 Yes, it is NACA3412. Not sure why I used that section as it was quite a long time ago. Probably something to do with the 3 views I was working with. It works well. l can't even remember where I got the 3 views from. It must be senility creeping (Galloping?) in.

THis is my standard construction and sizes, I have a G meter and on my Dancing Queen 53" span and powered by a Wankle engine I did a terminal velocity dive and hard pull out. The G meter registered 25.4 G which meant that the model weighed over 90 pounds briefly with no damage. Does that prove my point? Quote Link to comment Share on other sites More sharing options...
