Richard Wood Posted March 31, 2015 Share Posted March 31, 2015 It probably means sheeting all tail surfaces - fin, rudder, tailplane & elevator on both sides, with grain lengthwise. Quote Link to comment Share on other sites More sharing options...
trebor Posted March 31, 2015 Author Share Posted March 31, 2015 What do you think of these ? **LINK** Would I be ok using 3 for ailerons, elevator, rudder and get a cheaper one for the throttle ? Quote Link to comment Share on other sites More sharing options...
ken anderson. Posted March 31, 2015 Share Posted March 31, 2015 as above as stated by young bob for the servo's.....the one I had-I did as they recommend and covered the tail structure with sheet balsa..... ken Anderson...ne..1 mystic dept.

trebor Posted March 31, 2015 Author Share Posted March 31, 2015 Just found out that the last servo link is better for a boat, too sloppy for planes. Also having trouble finding mentioned servos.

john stones 1 - Moderator Posted March 31, 2015 Share Posted March 31, 2015 Well that is a very popular servo Robert and used by large numbers of folk wanting a stronger servo, as is the 625 of the same make so I would ignore that comment completely myself. I've used Hitec for years no complaints John servos Edited By john stones 1 on 31/03/2015 16:12:31 Quote Link to comment Share on other sites More sharing options...
Don Fry Posted March 31, 2015 Share Posted March 31, 2015 From bitter experience, a first low winger is still a learning tool. Stick a cheap engine in it. No first low winger ever saw its old age pension. Yer going to invert it sometime, and the result is usually interesting. Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted March 31, 2015 Share Posted March 31, 2015 645MGs would do, I have them in a 1.80 powered Christen Eagle and they're not sloppy at all but how about Savox 0352 or 0254 or for MG ball raced 0252MG - also available at other suppliers but easy to link to on Webb's website! I've got no complaints with the Savox servos I've used, they seem to be well made with overload protection and take standard Futaba style arms.

trebor Posted March 31, 2015 Author Share Posted March 31, 2015 Thanks chaps, I have a headache now. Those Savox look ok and cheaper Been looking on that Servodatabase. Quote Link to comment Share on other sites More sharing options...
ken anderson. Posted March 31, 2015 Share Posted March 31, 2015 when the mystic first appeared last century - don't forget we didn't have the Vast selection of servo's we now have to choose from.....so don't get too hung up about which one's to choose/use etc.....in fact I would have thought that it was designed around pretty much standard one's compared to what we have now.... ken Anderson...ne..1 last century dept.

ROY DAVIES 1 Posted March 31, 2015 Share Posted March 31, 2015 A great model. I used an OPS 120 four stroke and it would get away quite nippily. Touch and goes were a delight and on the approach it would almost land itself. I used standard servos and you should definitely use the original undercarriage, it had the correct sit and the 'rate' of the legs was spot on - no second bounce. I can't remember if it was supplied with a steerable tail wheel but mine did. I still have the spats as our patch was not friendly enough to use them. Making me all lustful now.

trebor Posted March 31, 2015 Author Share Posted March 31, 2015 What happened to it ? I'm starting to wish mine was finished now. Quote Link to comment Share on other sites More sharing options...
bert baker Posted April 1, 2015 Share Posted April 1, 2015 Well I am with Ken, The servo option was the reliable and trusted Futaba 148. The only difference was that on both of the ones I have owned I put the servos under the tail plane and had short rods. Yes although the under carage wire is quite chunky it will spring back and forward during touch and goes. I never had any problems with it and would keep it standard. Way back in the late eighties when I was poor I had my first one and I fitted a ASP 90, I also fitted a smoke system, I replaced the motor with a ASP 108. can't remember why. Have tried Saito 120 very good and Laser 150. SuperTigre 2300. Super Tigre 90. OS BX 108. All I would say is back in time My pocket dictated what I spent on engines, For me at that time if it said a forty size I would get the cheapest forty I could find, then if a club mate turned up with the same model but a nice OS on the front I would spend time wondering why my engine was not performing as well as the OS, I think we were all being slightly misled about engine size for a kit. OK the cc rating is important but so is the HP output It's an old design and was done with using standard radio gear.

trebor Posted April 1, 2015 Author Share Posted April 1, 2015 Did those larger engines fit under the cowel ok ? You didn't have to move the firewall back or extend the cowel at all. Quote Link to comment Share on other sites More sharing options...
bert baker Posted April 1, 2015 Share Posted April 1, 2015 Yes they would have as the cowl is huge, I personally didn't bother with it. I kept the engine Firewall standard, I would recommend Sheeting the tail feathers. Quote Link to comment Share on other sites More sharing options...
Richard Wood Posted April 1, 2015 Share Posted April 1, 2015 I found the Magician was easily prone to nose over with the U/C in standard position & eventually bent it forwards a bit - it might have been my inadequate ground handling skills mind! The Mystic isn't a Magician of course but perhaps something to bear in mind. Edited By Richard Wood on 01/04/2015 12:12:46 Quote Link to comment Share on other sites More sharing options...
trebor Posted April 1, 2015 Author Share Posted April 1, 2015 When you say sheeting the tail would that mean elevator an rudder both sides ? Quote Link to comment Share on other sites More sharing options...

Dave Hopkin Posted April 1, 2015 Share Posted April 1, 2015 Either 1/16th balsa or any old floorboards you have knocking about - it will help to counter balance that big lump of motor you are bunging in the pointy end Quote Link to comment Share on other sites More sharing options...
Stuart Z Posted August 13, 2015 Share Posted August 13, 2015 Hi I had one of these several years back. Flew on ST90. It performed a reasonable range of aerobatics, was slow and easy to fly. I could do very precise landings and used it to pass my A certificate with an impressed examiner! Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted February 21, 2016 Share Posted February 21, 2016 Thread resurrection - I picked up a second hand Mystic for very little and now I could use some info on the model. First, this example is quite nicely finished in either well sprayed Solartex or white Glosstex and sported a home made half cowl. It looks like it may have been fitted with a large petrol motor from the amount of cowl that's cut away and the odd engine mountings. I've replaced all the rather old control horns, freed up the wire in tube pushrods, bolted an OS 120 surpass up front , fitted a cowl from Pegasus models (£10 - very reasonable). For control I've kitted it out with a mix of spare servos that seemed to fit the bill - 3001s (3kg) on ailerons, BMS620 (10kg?) on rudder, two HXT5010 (5kg) on elevators and a 148 on throttle. The battery is a 5 cell Sub-C pack mounted in the tank bay. The shock came when I went to balance it - about half a pound of lead needed to get it balancing at about 30% chord! AUW is 13lbs which is more than I'd expected but I can't find any details on t'web to tell me whether this is just a bit on the high side or that I should be searching the tail for hidden engineering bricks. So - what did these normally come out at weight wise and does anyone know the recommended balance point? Quote Link to comment Share on other sites More sharing options...

trebor Posted February 21, 2016 Author Share Posted February 21, 2016 I must confess, I haven't started to build mine yet. I've got the plans in the loft so I'll have a look next week for the balance point. Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted February 21, 2016 Share Posted February 21, 2016 In an inspired moment I had a poke around under a little hatch beneath the tailplane that I thought was for access to the closed loop - no, it's a ballast compartment with 3oz of lead. I've now removed that and the 8oz up front leaving the AUW at 11lb 14oz - 8-8 for the fuselage and 3-6 for the wing. With no ballast at either end it's balancing around 4 3/4" back from the LE or 32% chord. Close enough. Brian, as for the 148 - I find plain bearing servos fine for throttle control, as long as it's not got too much slop. Besides it was already in there when I got it - this is cheap hack territory. Airframe - £40 Cowl - £10 Servos, receiver,extensions, aileron servo mounts, bit of white film for patching, spinner, prop, horns, aileron pushrods, tank, mount and engine - all out of the recycled box or spares. Total expenditure - £50 = worry free flying. Quote Link to comment Share on other sites More sharing options...
