Surface Deflection Indicator recommedations

Looking for something cheap and cheerful for future setup use other than cardboard and sticky tape :)

Something like this perhaps? (it cost about £15)

I just use a ruler!

Measure from centre to top and bottom, either eyeball an extended level or tilt the ruler to touch the surface, it doesn’t matter which way you measure as long as you’re consistent. 
 

We’re only really making sure things are even on either side :)

It’s merely a pendulum, simply attach the peg and zero the protractor

Have one of the above from Hobbyking - cost very little but more trouble than it is worth to me  - easier to set-up  with a ruler

The hi-tech solution. £60 from Nexus Hobbies. Works well.

I'm still using the gauges that came with one of my Stu Blanchard Calypso's 25years ago, a degree protractor printed out and spray glued onto some cardboard.P1010051.thumb.JPG.84cb0cfed56db426d345085d7d1e7f34.JPG

Hi John

#2!

A word of warning though....I stopped using my MT kit about 10 years ago, because all it seemed to be doing for me was pointing out the slop in my linkages.....following on from that I had a long discussion with a chap on the Beacon last year, between flights, telling me that he'd broken quite a few linkages on his mouldies because they had no slop and therefore no give, before they broke......sadly, another chap mentioned  he'd had to buy two VERY expensive flap servos last year because he'd had to land his pride and joy in high, gusty winds and, by the time he got to his 'plane in the long grass, the howling of his stalled flap servos had stopped and the puff of blue smoke had occurred (two separate instances):( for him a very expensive learning curve.......

Regards

Pete

I suspect degrees could be made to be mm

On the Digitech device you can set the width of the surface at the point where you want to make the measurement, and it will provide the mm equivalent of the angle.

Thanks for all the replies gentlemen, much appreciated.

Such an interesting variety of devices.  The 3D printed ones look really simple and functional, also like the look of the hi-tech solution...

I was lucky enough to get a set of the 3D printed ones from Tony.  Simple no-frills design that does the job. Marvellous. 

Cheers Tony!

Just been re-setting control surfaces on my Longshot1 for a first flight today hopefully. I Just wanted to thank Tony for his throw meters, nice one Tony! 👍

I have just had this thread pointed out to me and thought you may be interested in an Arduino based “Deflection Indicator” that I recently made as a “lock down” project. It has proved ideal for setting surfaces on my F5J gliders, partially balancing the Flaps and V-Tails.  It simultaneously measures the movement of a left and right surface, either in degrees or vertical deflection, for +/- 90Deg. 

At a component cost of little more than the commercial mechanical gadgets based on cloths pegs and protractors this project is well within the capabilities of anyone that has a little computer knowledge, a few soldering skills and access to a 3D printer (for the case), ie most modelers.  See attached photos and video (at: https://www.dropbox.com/s/vhifwbmjz46co2z/Throw Meter video 3.mp4?dl=0).   If there is serious interest in this project then I may start a build post.

Looks very interesting. It's such a drag setting up pairs of surfaces.

That’s very nice.  Would you be willing to share the sketch and other info?
