ericrw Posted March 1, 2012 Share Posted March 1, 2012 I've just bought this ARTF model 82"wingspan. Though it is intended for i/c power, I'm hoping to convert it to electric power. If anyone has experience of this model and certainly if they have carried out the same conversion I would appreciate their advice ! Quote Link to comment Share on other sites More sharing options...
Peter Wood Posted May 7, 2012 Share Posted May 7, 2012 I am looking for a electric piper cub, of about 80" span and would like to know if it is possible.. I have tried one convertion, but it waswas not possible to fit the cowl Peter Quote Link to comment Share on other sites More sharing options...
ericrw Posted May 7, 2012 Author Share Posted May 7, 2012 I've found my Thunder Tiger Piper Cub, very easy to convert from i/c to electric. It has a wingspan of 82.7" Quote Link to comment Share on other sites More sharing options...
Biggles' Elder Brother - Moderator Posted May 7, 2012 Share Posted May 7, 2012 I've had a hankering to see what "bigger" electric is like. So I'm doing an electric conversion of the World Models Cub at the moment. Its 76" span - so just a little bit smaller. I've not had problems so far. I had to relocate the firewall captive nuts and I'm currently reinforcing the ply formers in the tank bay to take the battery. I intend making the side panel (which is handily a separate unit) hinged so I can get the battery in and out without taking the wing off. Power is a EFlite Power60 with a 6s battery and 80amp ESC. I'm considering fitting a sound system once its maidened - the bit downside of electric for me is the loss of the lovely 4st sound!

Martin Harris - Moderator Posted May 9, 2012 Share Posted May 9, 2012 Never seen so much enjoyment, Eric! But BEB, what's happening to you? An electric Cub??? Have you considered seeking professional help for your condition?!?! Edited By Martin Harris on 09/05/2012 14:12:35 Quote Link to comment Share on other sites More sharing options...
ericrw Posted May 9, 2012 Author Share Posted May 9, 2012 BEB, you might as well go electric as, despite Martin's remarks, I/C doesn't really sound like the real thing, now does it !!! Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted May 9, 2012 Share Posted May 9, 2012 Hey, I never claimed it did - but it's a lot more "real" than a whining electric motor (which I don't deny has practicality). We've done the EP/IC debate to death before - I'm just concerned over BEB's state of mind. Perhaps some kind Northern soul could pop over to the Wirral with a dampened copy of an old Peter Chinn engine review to apply to his obviously fevered brow?

Biggles' Elder Brother - Moderator Posted May 9, 2012 Share Posted May 9, 2012 Sorry Eric, in trying to remove the dupliacte posts I've accidemtally deleted your original as well The trouble is the forum is so damn slow I'm getting confused whether I'm looking at the current page or the previous one. Sorry again mate. Re electric - yes gliders next for me Martin! No seriously I just fancied finding out what could be achieved with a larger electric model. As I say I'm planning some experiments with a on-board sound system. Its all good fun! I'm not planning on mothballing my engines Martin - don't worry!

ericrw Posted May 10, 2012 Author Share Posted May 10, 2012 I'm getting there but one photo has been duplicated. The problem appears to be that the time span between "insert image" and actually responding is lengthy Quote Link to comment Share on other sites More sharing options...

ericrw Posted May 10, 2012 Author Share Posted May 10, 2012 The Motor is a G46 from HK. I entered underneath the fuselage to install a battery;as you can now see by the photo. Quote Link to comment Share on other sites More sharing options...
ericrw Posted May 14, 2012 Author Share Posted May 14, 2012 I'm now ready to maiden my model but I was asked as to what degree of off-set had I allowed. Can anyone advise me on this matter as this is too technical for me !! Quote Link to comment Share on other sites More sharing options...
Pete B Posted May 14, 2012 Share Posted May 14, 2012 I think they mean the amount of right thrust and down thrust you've set on the motor, Eric. If you haven't set any, the Cub will tend to turn left and climb at higher throttle settings. With that mount, you can easily adjust it to put in a couple of degrees of right thrust and about the same of down. That should make it behave quite benignly through the throttle range.......

ericrw Posted May 15, 2012 Author Share Posted May 15, 2012 Hi, I assume it will be best to maiden the model and see how she performs but also be aware of the tendancies that you refer to. Eric. Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted May 15, 2012 Share Posted May 15, 2012 Many models have the side and downthrust built in to the firewall so you may not need to add any. Quote Link to comment Share on other sites More sharing options...
Pete B Posted May 15, 2012 Share Posted May 15, 2012 I've just had a look at the build manual and see that 2 deg right thrust is advised (photo 66); photo 67 shows the engine mounted and there appears to be a tad of downthrust built-in on the firewall, as Martin suggests. An examination with the Mk 1 eyeball should resolve it...... Pete Quote Link to comment Share on other sites More sharing options...
ericrw Posted May 15, 2012 Author Share Posted May 15, 2012 The manual refers to fitting an i/c engine,as to whether an electric motor will be any different ??? Quote Link to comment Share on other sites More sharing options...
Pete B Posted May 15, 2012 Share Posted May 15, 2012 Nope, thrust lines are the same for either Pete Quote Link to comment Share on other sites More sharing options...
