thanks V.

The second one (Sullivan) You can use a Li-Poly battery without a regulator on it so total weight will even be lighter

I have been using the TME for many years and hve not had one problem. both would be fine. Room is the only issue with smoke. Make sure the placement does not change the CG. Dennis

Dennis is correct. I use both as well. In a tight spot the Sullivan is a bit better. In physical size the TME is basically a windshield washer pump with resistors and such attached it to and is a bit fat and round but short. The Sullivan is a rectangle about the same height, a little narrower than the TME but a bit longer

Weight wise the TME is a bit heavier, now I do not know the exact difference but it's probably close to an ounce or so. Unless they have changed, the TME cannot use a Lithium battery up to a 3 cell so the battery weight alone makes that setup heavier than the Sullivan. The Sullivan can use any battery type up to a 3 cell Lithium

And I just thought of another smoke pump and that is the 3W one. It does not need a separate battery as it uses the power right from the receiver but you should increase your receiver battery. Cactus Aviation and Aircraft International sells them

The Sullivan seems to prime itself fairly well too.
