Default Visionaire Pilots, Prop Question

Any of you Visionaire pilots use a prop other than the factory 12 x 4?

I dont have a Visionare but on other 3D models I've found a 'half-square' (12x6 in this case) works best. Much less than half square tends as a rule to be lacking in speed and quite inefficient for anything but hovering.

You would of course have to watch your amps if you went to a 12x6.

Nope I use that stock prop and really love it.... I know many change it for a bit more speed but this is not a go fast plane for me. That said I am still happy with the overall speed, but lets face it, that is one draggy airframe...by design.

Thanks guys I should have added that I am not looking for more speed. My issue is 12 x 4E is hard to find in my location and looking for alternatives. My local Hobby Shop has APC 12 x 4 in, but my spinner will not fit unless I modify it.

Yeah I just ordered 4 factory props. Noticed in the charts 12 x 6 was a bit much for motor and ESC.

Now if I could just get the dang elevator from oscillating.

Mine does that too. You just have to move the elevator stick on the tx a little and it will stop. My Addiction x does it as well. Think it's because of the huge amount of movement and huge area of the elevator.

When you talk about the elevator oscillating... is that in flight or when sitting on the ground?

Oscillating when sitting on the ground seems to be something that some digital servos do after they have a little bit of wear. I stop it by putting a tiny piece of the 'fuzzy' side of velcro tape on the inside of the elevator balance, so that it rubs on the fixed part of the tailplane as it passes the centre position. This adds a tiny amount of friction damping which is very effective in stopping the oscillation.

If it happens in flight then it's probably gain too high, as mentioned in the other thread.

Try backing off on the elevator throw. I cranked up the throw on mine and ran into the flutter. Backed it off and everything was fine. Try either coming in on the servo arm or out on the elev. horn. If it doesn't work, nothing lost.

In flight. It is enough you can clearly see the elevator flutter. Back off the speed a bit and it quits. Having said that the manual does mention this problem and recommends backing off the throttle as the plane is moving too fast. My issue it before it only happened at high speeds with open throttle. 2/3 has always been good up until something changed.

Hey Gord are you talking about Throw Percentage setting on the radio?

If so you might be onto something I had not thought about until now when you brought it up. I downloaded the radio setup file from Spektrum for the Visionaire and did nothing to it because I like it. Point is I know all the throws are programmed to 125%. Is that what you are talking about?

I'd have to take the wing off to see where the throw is on the servo. Also the throw on the elevator is programmed in the DX9 at 100%.
