Propeller style question

Posted by Robert Beatty on December 4, 2010 at 3:41pm

I have a 1000-gram custom-frame aluminum Arducopter and KDA20-22L motors. I have been using APC Slow Flyer Propellers 10 x 4.7. These work fine.

I also have a batch of EPP 10 x 45 propellers  that I'm thinking about trying. (These are the props specified in the new DIY Drones Arducopter kit so I was curious to try them out on my unit).

Since they are the same length, and similar pitch (although not exactly the same obviously), I'm assuming they will be OK also. (I plan to use all the same type during a flight, not mixing them).

Does anyone know how the two props will differ in terms of flight characteristics (and other attributes that might be relevant)?     

(I don't know if this is relevant to my question or not, but my goal is stability and steadiness, rather than performance and acrobatics)

    OK. Thanks for the info, guys. That's exactly what I needed to know.

    I agree with the easy to break with the APC. The slightest contact with the ground, even grass, will cause them to fracture. I have only broken one EPP prop and bent two. Very rugged and not as temperature sensitive as the APC. I actually found that my quad flew better with the EPP than the APC. In the end it becomes a personal preference and may be dependent on how you fly.

    I used the EPP and they were very resistant to crash damage.
    Now I am using the APC and they break much easier.
    I like the APC better because they seem to respond faster to motor rpms. Better hover and response.
    I just carry more spares since they will break easier.
    Eventually I won't crash so much and then all will be better.
