Incidence / Throw Meters

[Dave Smith]

 I believe a 36" bar is available,but that won't help much if the rest is not good.

  I also just received my new Hangar 9 digital throw/incidence meters from Horizon and am somewhat disappointed.  I already had a digital level on my incidence meter so I was actually more interested in the digital throw meter function.  While it works, it does not have a counter balance to unload the surface as previously indicated/implied and it is very hard to reset the meter to zero without moving the meter resulting in a non zero setting.  The holder for the digital meter as a throw meter is relatively heavy; even tho it has soft rubber pads on the clamping surfaces, it is fairly easy to change the angle of the clamps because both sides of the clamping surfaces pivot as opposed to one surface being fixed and the other pivoting as in the CRC throw meter.  We were able to measure throws to .1 degree as advertised but it too some 'futzing' to get there.  In less than 10 minutes, we came up with several ways to make this setup better. Neat idea, wish they had taken more time to actually think through how it really works and how modelers would use it.  I already started making a new counter balanced surface mounting clamp for mine and am looking for a longer bar for the incidence meter part. It is woefully short for the wings we have if you want to measure near the root. 

  Like I said, neat idea, they should have spent more timing thinking or having some modelers test it first before release.  It would also be nice if we could just buy the digital component and skip the rest.  As designed, the CRC Throw Meter and Budd Engineering throw meter are much more user friendly.

    A while back I made reference to the (then yet unreleased) Hangar 9 Angle Pro Digital Throw / Incidence meter as a possible option for this task. Sorry to say that the two that I received are disappointing - one was inoperative, the other worked well for a little while and then failed. (The length of the "incidence bar" is too short unless you wish to measure incidence near the wing tip also. ) Postings on RCU suggest that my experience isn't an isolated case.
