Mark Powell 2 Posted August 30, 2012 Share Posted August 30, 2012 There was a talk of the Optica. The Sipa 2000 'Minijet' was a French (?) plane many years earlier. No connection with the much later piston engine Optica at all. Any 'pusher', such as the Optica effectively is, or very small jet almost dsigns itself that way. It had a small jet engine, A Turbomeca Astou or something, and like all these they are difficult for EDF the intakes are so small. For modelling the Miles Student has the same difficulties. There was a 'Model Aircaft' plan available for the Sipa Minijet many years ago for a Jetex 150 Jetmaster. Slightly smaller than yours, but much lighter as it was, of course, free flight. Also a smaller one for Jetex 50 in a 'multi plan set' of various small planes from Aero Modeller. I sent off for the 'Model Aircraft' plan and built one. Nice to see something similar 50 years later.

kevin wild Posted September 7, 2012 Share Posted September 7, 2012 Hi fantastic. add sculptor to your list of modeling skills hope you're enjoying the summer "flying" and not just making loads of dust in the shed ? Kev Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted September 7, 2012 Author Share Posted September 7, 2012 Hi Kevin , Yes i have been doing a lot of model flying while we have had some nice weather , a lot of the time with my son and his new trainer , Which he enjoys doing rolls with . I have been out quiet a lot with many models including the Sipa even let a couple of are club members have a go of it too . One Guy flew my Sipa so low and fast it even made me go geeess . in fact it now goes so fast i am going to get it`s speed recorded at are clubs festival of speed do . I have also been asked to make one bigger a lot bigger as he likes it so much but doesn't do small models . For now i think we can safely say this project has come to its end . This one i am happy with and it has turned out better than i had hoped for and also flies better than i could of hoped for , even if i do say so myself , Hmm now where is that smiley blow you're own trumpet .

Stephen Jones Posted February 17, 2014 Author Share Posted February 17, 2014 Oh My God , I got bored and was looking through old posts and found that this one has slowly crept up to over 10,000 views and it`s over four years old . Boy doesn't time fly by . I am sure it was no where near that figure when i left it . . Quote Link to comment Share on other sites More sharing options...
Ton van Munsteren Posted February 17, 2014 Share Posted February 17, 2014 Stephen, Must be great knowing that so many have been looking at the pics. Iam sure they have been enjoing it because its a lovely model. Cheers Ton Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted February 18, 2014 Author Share Posted February 18, 2014 Hi Ton , Well it`s nice to see there is still some interest in it . Most of my build logs do not seem to get to these dizzy heights . Usually once a build log has got so far down the list no one sees it, and there for it remains to stagnate. So someone or some people are actively seeking it out but whom as they are clearly not users of this site other wise they surly would have passed comment . It certainly is strange to see the viewing figures to continually rise and not remain stagnant . Steve , Quote Link to comment Share on other sites More sharing options...
Down Under Posted February 19, 2014 Share Posted February 19, 2014 Hi Stephen I'll go one better. Are there any plans for this? I think it is a great looking little plane that I would love to build. Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted February 19, 2014 Author Share Posted February 19, 2014 Hi Down Under , Only the plans i drawn for myself as it is a scratch build . Cheers Steve , Quote Link to comment Share on other sites More sharing options...
Down Under Posted February 19, 2014 Share Posted February 19, 2014 Hi Stephen. Thanks for the quick reply. Hmmmm. I see Outerzone has plans for a 24" free flight version. Wonder if I could successfully enlarge these? Wonder how much work would be involved in modifying it and making it a ducted fan version? Maybe I'm getting ahead of myself....

Stephen Jones Posted February 19, 2014 Author Share Posted February 19, 2014 Hi , The free Flight jetx model is not too scale the body shape is wrong and the booms are too long , it was built to be stable for free flight , Ducted Fan would also need the rear opening up too allow the air too flow out quick enough so once again would not look scale . Having said that there are so many models that have been successfully adapted too look like they are scale . Why not give it a go nothing ventured nothing gained . There is a jet Sipa 200 model on you tube do a quick Google and judge for you're self . Cheers Steve , Quote Link to comment Share on other sites More sharing options...
Ton van Munsteren Posted February 19, 2014 Share Posted February 19, 2014 Stephen, Why not send the drawing in to RCME, with so much views iam sure there are modellers out there who want to build there own. Ton Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted June 8, 2014 Author Share Posted June 8, 2014 Hi , I have made a Launch Dolly for the model so i do not have to rely on someone being there to hand launch it for me . It is made from depron and so is very light and with the large wheels should get through the grass with ease . I haven't tried it yet , so I hope it goes ok . I also need to make one for my CanDoo . Ton i did try to give Graham the plans when i meet with him at Greenacres i have also flown the model their on several occasions .

Stephen Jones Posted June 15, 2014 Author Share Posted June 15, 2014 Hi , I decided to sneak out this dull morning to give the Dolly launch a go . I am glad i did as it works perfectly , i only wish i had tried this method much earlier as now i do not need to rely on someone being there who will hand launch it for me . Sorry my daughter Evelyn took the video and the weather is grey and damp . Steve , Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted June 28, 2014 Author Share Posted June 28, 2014 Hi all , Some of you may have been to the Greenacres / RCM&E due this year and seen me there with my Sipa 200 Models . You may not of seen me fly one of them for Graham Ashby , as it was at the end of the Saturdays due , Well it may of been a long time coming but now that Graham has all the pictures he needs (hopefully ) the plan will be in the RCM&E by the end of the year . I believe that Graham will be doing the build write up and Nigel Hawes will be doing a Scale feature on the Sipa S-200 to go along side it . I have been going though all my old notes to add to the the plan and build log and any additions to be put on the plan and as soon as that is complete i will send them of to Graham . So for those of you that have shown interest in this model , watch this space and for now here is a Picture that Nigel has sent me . Thank`s Steve , Quote Link to comment Share on other sites More sharing options...
Colin Leighfield Posted June 28, 2014 Share Posted June 28, 2014 Great news Stephen, you've got a winner there. Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted June 28, 2014 Author Share Posted June 28, 2014 Thank`s Colin , It was nice to speak with you at the show , It was a shame i did not fly it earlier for you to see , But the flight line was a bit too hectic for my liking and that cross wind was not for me i am afraid . As it was at the end of the fly in the flight line became quieter but there was two large planes hovering around in front of me which put me off and it had to be hand launched into wind . Thanks very much to Richard Harris without you're help i doubt Graham would of got his Photo opportunity . By the way Richard did you manage to Video it ? .

Ton van Munsteren Posted June 29, 2014 Share Posted June 29, 2014 Steve, Thats great news that the Sipa will go in the RCME. Cheers Ton Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted August 6, 2014 Author Share Posted August 6, 2014 Thank`s Ton Yes it has been confirmed That My Sipa S-200 will be going in the RCM&E as a free plan and if you have a copy of the September issue Of RCM&E you will see a picture of it on page 18 . I have sent a PDF of the plan into Graham and been checking over the specs for this little rocket ship and the motor i used where very common at the time but now seem to be in short supplies and so if anyone is considering building this one i suggest you make sure you get the motor while you can i have found two site that have similar motors to the ones i used . As the motor needs to fit inside the model a maximum diameter of 28 - 30 mm is recommended and as we need a 250 watt motor driving a small prop a high 2200 Kv is also needed .

Stephen Jones Posted August 6, 2014 Author Share Posted August 6, 2014 Hi, Also if any of you are concerned about hand launching this one i also tried bungee launching and so made a tow hook which fits on the belly which i will share with you . I Also made the launch dolly . Steve Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted October 6, 2014 Author Share Posted October 6, 2014 Hi , As this is a one piece model with no wheels there are three way you can get this one airborne . 1. And most obvious is to hand launch which for the 1st few flights i would recommend a experienced helper to throw it for you . 2. Use a launch dolly. 3. Use a Bungee for which you will have to make and fit a Tow Hook . And here is how i made my Tow Hook. Three pieces of ply a small magnet and a small piece of brass tube squashed over a bit of bent wire. Assembled like this will allow the hook to self close after use. Make sure that you make the hook with the z bend and not the straight arm as above , as you're Tow hoop may get stuck don't ask me how i know .

Stephen Jones Posted October 6, 2014 Author Share Posted October 6, 2014 This Tow Hook can then be fitted to the underside like this . A nice and discreet Tow Hook which could also be used on any model . Steve . Quote Link to comment Share on other sites More sharing options...
