Minimizing Spit Back On RDA

[VaporDaze]

Just curious if anyone has a solution to minimizing the spit back on an rda? Would slightly tilting the coils have any effect as there isn't room to do certs in my rda. I'm currently working with a royal hunter Mini I picked up last week and I'm absolutely loving the thing minus the spitting.

Get used to it? jk

 

[smacuser]

Jk. What are you wrapping?

watts?

If you're looking at microcoils, so be it.

My next build would be 28 with spaces.

On a mech, rough guess would be around 85. I'll try that, I have some laying around somewhere

Try moving the coils a little closer to the air inlet rather than the middle near the posts. You'll have a little bit longer legs, but it'll kick the spitting down.

This ^^^. Also use a bigger bore drip tip.

I'll third the coils closer to the airholes. Also, don't over drip and don't inhale so hard.

Use a lower VG eliquid, 50/50 is good.

Three causes:

1) the coil is sitting in a puddle of juice and spits due to boiling outside the wick

2) under powered (too much air), the coil is too cool, localized evaporation occurs causing juice elsewhere in the wick to be ejected as a hot liquid

3) not enough air (too much power), so much liquid is vaporized in a short time the particles collide in the chamber forming larger droplets

When referring to wick above, I am referring to the portion inside the coil.

Try moving away from the mini rdas for a change, go for something taller (the Infinite CLT V2 or V3 come to mind).

Too thin a wick inside the coil and its a mini. Haven't seen a mini that doesn't to some extent, nature of the beast. I thought the RH had a piece to stop it, even on the mini

Follow these suggestions, they are more than likely the issue. Spitting is an indication that something is off rather than normal operation. It can happen in any build, but after the wick is broken it should not be spitting back at you all the time. Sometimes after I saturate the wick I give it a quick pulse to see if I have any excess liquid that didn't move all the way into the wick, if I do then this liquid can possibly shoot out, but it should not happen draw after draw.

A RDA build can shoot/spit streams of liquid outward if there's a wicking issue. If you over drip spitting can happen too. Take off your top cap and fire it to see what it happening. I feel like you have issue #1 or #2 in the above quote.
