Carl Muff Posted November 2, 2008 Share Posted November 2, 2008 Hi alli have been give this old plane ,and was wondering would it be difficult to covert it to 3 channel electric flight .its bare no servo tray and the rudder and elevator is one unit held on by rubber .but other for a couple of holes it seems in good condition .any help would be grateful Quote Link to comment Share on other sites More sharing options...

Carl Muff Posted November 3, 2008 Author Share Posted November 3, 2008 ok will do ,sorry Quote Link to comment Share on other sites More sharing options...
Michael Dearden Posted November 4, 2008 Share Posted November 4, 2008 Looking at it I would say almost certainly yes. There are motors/batteries out there that will lift just about anything but yes, it would be nice to know the weight, wing area etc. As it has wheels, presumably it used also to have an engine of some sort and, if it had a petrol or diesel engine, then there is certainly an electric set-up that will do the job.

Carl Muff Posted November 4, 2008 Author Share Posted November 4, 2008 the weight is 1 lb ( around 500gs) the wing is 120 cm by 23 cm the hose has a wooden point ,cant see anything that shows its had a engine mount to the front Quote Link to comment Share on other sites More sharing options...

Andy Gates Posted November 5, 2008 Share Posted November 5, 2008 Or it could have used a power pod attached to the missing hatch.It looks a bit like a Veron Impala with an extended nose.A slightly better / bigger picture may help especially of the nose section from the wing forwards.I would agree with Michael, there will be a motor / battery / prop combination which will suit this machine fine. I would start looking at a 3S 2100mAH lipo, a 10" folding prop and a brushless motor in the 28mm outside diameter range with a kv around 900 just to give you a vague idea.More details would of course help.

Michael Dearden Posted November 5, 2008 Share Posted November 5, 2008 With that long nose you're going to have to be careful with the C/G but an 11.1v lipo setup will surely do you just fine with the battery probably just forward of the wing or possibly half/half and the servo try under the wing. I presume it has a rudder and elevator??? Quote Link to comment Share on other sites More sharing options...
Carl Muff Posted November 5, 2008 Author Share Posted November 5, 2008 thanks all ,and will do some better pictures .the tail section is one piece no rudder or elevator .any details you need just let me know and i get them it does have a name on the side pitts 74 s although that could just be a sticker Quote Link to comment Share on other sites More sharing options...

Tim Mackey Posted November 5, 2008 Share Posted November 5, 2008 Well if it has no elevator or rudder, and I can see no signs of ailerons....one has to wonder how it ever flew!If it was me, I would add rudder and elevator, fix the tailplane permanently, and then weigh the result. Add approx 50% to allow for a leccy tractor setup, receiver and 2 servos, and whatever the total comes out at calculate the powertrain at approx 100 watts per pound of AUW. So assuming AUW of approx 1.5lbs ( which seems pretty light to me ? ) you need a setup capable of 150 -200watts. Plenty to choose from in the likes of BRC and other online shops....and at pocket money prices too. Quote Link to comment Share on other sites More sharing options...

Michael Dearden Posted November 6, 2008 Share Posted November 6, 2008 Ah - old age can help there Timbo. The very early elastic powered planes I built, circa 1940/50's didn't have any control surfaces. Just wind then up, point them into the wind and let go! Hopefully they flew reasonably straight and didn't come down too hard! One of the biggest danders was over winding the elastic! Then the tail tended to come up and meet the nose with a loud "snap" and the fusalage was reduced to a load of broken balsa and tissue paper!

Tim Mackey Posted November 6, 2008 Share Posted November 6, 2008 I do remember rubber free flight Michael, but figured this one looked a little too large ? Glad to report however that 40 /50s is just a tad before my building time - I was born in 51 Quote Link to comment Share on other sites More sharing options...
Michael Dearden Posted November 6, 2008 Share Posted November 6, 2008 Wish I could say that Timbo having been around since '38Quite an interesting project though and not too difficult to convert the tailplane into rudder and elevator, and yes, it also has solarfilm or similar covering so comparatively "young" Quote Link to comment Share on other sites More sharing options...

Michael Dearden Posted November 6, 2008 Share Posted November 6, 2008 Not far off Phil! A brief history copied from their website:- In 1968 the Manufacture of SOLARFILM iron-on film started in Chorley, England with just six basic colours. 1973 Solarfilm manufacture moved to a larger factory in Blackpool, England. By then the colour range included transparent and metalic colours.1979 Solarfilm moved back to Chorley into a larger purpose-built factory, doubling the floor area again.1982 SOLARTEX, the iron-on fabric was developed and put into production Quote Link to comment Share on other sites More sharing options...

Carl Muff Posted November 6, 2008 Author Share Posted November 6, 2008 yet again thanks all ,had a closer look and you can see where a servo was ,also 2 inchs of the nose is new balsa wood then the rest and you i think i can make out a fire wall . the under carriage is nearly as heavy as the plane its self .im going to fix the tail plane and put on a rubber and elvator and replace the servo tray for starts Quote Link to comment Share on other sites More sharing options...
Andy Gates Posted November 6, 2008 Share Posted November 6, 2008 I hope you mean a rudder and elevator, a rubber may well make your plane a little vague in control response. Quote Link to comment Share on other sites More sharing options...
