Bernard Dolinski Posted August 16, 2012 Share Posted August 16, 2012 Well mine wont be built for a while as mum said to make a list of what i want for christmas. So im going to go with one of the thunder tiger 07 motors, 0.069cu so it should be good. Along with balsa servos rx etc. Quote Link to comment Share on other sites More sharing options...
Daniel Page Posted August 27, 2012 Share Posted August 27, 2012 I am a big fan of your designs Peter (and adaptions of other designs), even though I haven't built one yet I would like to build this as camera platform for my GoPro Hero but will go for electric power instead of IC. Other than making sure the CG is correct would there be anything else I need to keep in mind doing an electric version? Do I use the same down/side engine thrust angles as mentioned in the article?

richard shorrock Posted August 28, 2012 Share Posted August 28, 2012 Hi Peter, I am known as a light builder and have also built and flown my own design all vintage One electric at 52" which i call the joker and a 60" ic with a OS25 which i call the Wizdor. These are both floater and are great fun to fly. I have just finished the Sandow electric The battery is in front of the centre line between the fire wall and under the motor I have done this so as to put all the heavy stuff right up at the front. But the amount of lead i needed to balance it was to much even when i put it under the motor and i also could not accomdate the mass. This was complitley finished cover and everything. So i thought the only thing i could do was to turn it in to an i/c which is what i did. This was a big job i had to get rid off the shoot and make a fuel tank bay where that was. I put a os15 no a plastic mount and before i went any further i tried to balance it same thing. Can you tell me if you had to put much lead in it. Regards Rick I have built the sndow Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted August 28, 2012 Share Posted August 28, 2012 I did have to add quite a bit of lead. I can't remember how much but the all up weight indicates quite a bit. Main point is bring the CG to the indicated point. The original was a free fligher with the CG much fuirther back than the current design.

Bernard Dolinski Posted September 10, 2012 Share Posted September 10, 2012 What is a good electric setup? I MIGHT be able to start building it over the holidays here. Im rhinking a 2s setup with a mother of a big battery so a) i wont need AS MUCH nose weight. B) ill be able to have a few flights with the one battery and help keep the cost down.

Peter Miller Posted September 10, 2012 Share Posted September 10, 2012 I am sure someone will be able to tell yu what set up to use for electric. Getting a large battery far engouh forward minght be a little difficult but I know nothing about batteries Quote Link to comment Share on other sites More sharing options...
NealeG Posted September 10, 2012 Share Posted September 10, 2012 A suggestion for an electric motor set-up would be a 2212-06 (2200kv) motor, availabe Giantshark for a little less than £9. That way you could use your 2cell Li-po battery. You wouldn't need anything bigger than a 30A Esc and if you study the motor spec they advise on prop sizes suitable for the motor and battery set up.

NealeG Posted September 12, 2012 Share Posted September 12, 2012 As my Sandow nears completion just a couple of things to do, like covering the main wing and then deciding what size silicone or rubber bands I need for both the main wing and the tail stab/ fin. If anyone can help with a recommendation on sizes it would be greatly appreciated. Quote Link to comment Share on other sites More sharing options...
NealeG Posted September 23, 2012 Share Posted September 23, 2012 Sorted the rubber bands out 4" will do for both main wing and stab, if anyones interested. Quote Link to comment Share on other sites More sharing options...
NealeG Posted October 4, 2012 Share Posted October 4, 2012 Finally finshed the model and giving her a test flight today. I used a OS15 and I needed a tonne of lead up front. Watch this space. Quote Link to comment Share on other sites More sharing options...
NealeG Posted November 8, 2012 Share Posted November 8, 2012 Maided flight went extremely well its a pussycat to fly. The only problem was take off, the model has a mind of it's own skating around in every direction conceivable so I ended up hand launching her. Another brilliant Peter Miller model. keep um coming Peter.............. Neale Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted November 8, 2012 Share Posted November 8, 2012 Glad to hear of another happy modeller. Bit puzzled about the take off problem. Mine took off straight on grass. Mind you, with the power it didn't roll far anyway. Quote Link to comment Share on other sites More sharing options...
ian ludwell Posted December 10, 2012 Share Posted December 10, 2012 Hello all, Did start to build this a couple of months ago,but other builds took over.plus cold weather. So now i have sent for the laser cut parts along with the Pix-e-major parts (Tim Hoopers offering) So the only part i have started is one fuz side. Do we have any completed elastic trikery models,and what set up are you using. Does it require extra weight to compensate for lack of engine. Will post some pics on when parts arrive in next few days. Good building..Ian Quote Link to comment Share on other sites More sharing options...
ian ludwell Posted January 15, 2013 Share Posted January 15, 2013 Hello all, All seems quiet on here,has everyone stopped building or are all builds complete? Any pics of builds or completed models to look at. My CNC cut parts for the Sandow and the Pix-e Major arrived, Have done some building on both. Regards ..Ian Quote Link to comment Share on other sites More sharing options...
Brian Cheyne Posted May 19, 2014 Share Posted May 19, 2014 Here is my leccy powered Sandow. I have made it into a toffee bomber with the bay just behind the CG. It is lots of fun! Quote Link to comment Share on other sites More sharing options...
Brian Cheyne Posted May 19, 2014 Share Posted May 19, 2014 I want to fit my 3.5cc (.021 cu.in) MVVS two stroke in my next Sandow fitted with a 8 x 6 prop. My thinking is this engine is heavier and will lessen the need for extra lead. Any comments from forum members? Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted May 19, 2014 Share Posted May 19, 2014 Very Nice. Glad that you are having fun with it. I can't help feeling that nearly doubling the power will be rather over kill. It is basically a free flight model. Maybe if you scaled it to 60" span it would be better with the .21 Peter Edited By Peter Miller on 19/05/2014 08:29:14 Quote Link to comment Share on other sites More sharing options...
peter harvey 1 Posted May 29, 2014 Share Posted May 29, 2014 Have just flown my Sandow fro the first time, take off was novel, all over the place, so hand launched. It flew well but seemed to adopt a nose up attitude, as though tail heavey, which it wasn,t, also rudder was fairly insensitive (possibly blanked by fus. One of our older members who has flown ff for years reckoned it was nose heavey, which seemed strange as I would have thought the opposite, it dossent balloon when the throttle was opened fully. Has anyone got any ideas?????? puzzled of Stockport Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted May 29, 2014 Share Posted May 29, 2014 Some people seem to have squirrely models and others don't. If it balances in the right place it should perform as described. The fact that it doesn't zoom on full power could mean it is nose heavy or more down thrust than original. It seems to vary much more than other models that I have converted.

peter harvey 1 Posted May 30, 2014 Share Posted May 30, 2014 Thanks Peter, will try reducing lead first, then maybe try playing with tail and wing incidences, unless someone else has a brainwave. love your designs, my Harlequin flew brilliantly until recently I thought I could fly in the gap between the top of the trees bordering our club and the low winter sun, big mistake, I have just started on the Big Ship, and hope this flys as well. Many thanks for much fun Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted May 30, 2014 Share Posted May 30, 2014 The Big Ship is a really nice model. IT was originally designed as an R/C model and the orginal Little Ship at 44" was an incredible model. Everyone in our club built at least one. They would fly in quite strong winds. I would suggest a good OS 35 to 40 FP for your Big ship or even a 40 FS. NOTE Make the wire "V" on the undercarriage that goes under the fuselage out of much thicker wire than specified on the plan. at least 10 SWG.
