Forcer being inconsistent, seeking alternatives

[FuzzMaster]

Hi.

I recently built the most basic of basic wired flying contraptions. Attempted a form of weaponry by having the following setup:

A prop spawner located above a forcer. Upon the press of the button, the prop will drop onto the forcer, and in a perfect world, be flung forward to kill whatever lies ahead, no problem.

However, I do seem to have problems. OCCASIONALLY, the prop will fall down and get pushed ahead as planned, but more often, the prop will just fall through the beam and de-spawn two seconds later.

My question is, has anyone else had this issue? I googled around to no avail. I tried using the Adv. Dupe prop spawn that would spawn props with thrusters on it so I wouldn't have to muchk about with dropping things n the forcer, but it's awfully clunky and seems fairly incapable of doing exactly what I need.

Thanks.

Which prop are you using? I put a prop spawner to spawn a brick above a forcer and the forcer has produced the desired effect (flung the brick at a combine elite) several dozen times in a row.

I tried this with explosive barrels. The only time it failed is when I double-tapped the spawn key and the barrels spawned inside of each other, clipped, then shot off to different sides.

A variety of things, including the saw and cinderblock, the latter which I would prefer to use. I will upload an Adv. Dupe if you want to play around with it.
