Actually looking at this hand after I allready posted it I think it's clearly a fold. I have 7 outs (4 fives and 3 Aces assuming that hea has a pair).

First off, the pot is small, so folding ain't bad. 

Against three players, that flop probally did hit anyone and not too drawy. I would have bet the flop.

You only need to get them both to fold one time out of three for the play in and of itself to be break-even. But that not why I'd bet. Here are the gravy reasons.

Betting will help disguise your bets. If you end up checking the turn if it doesn't help. People may remember that and give you a bit more action later on.

The turn may help you. There a in four chance a heart will come. At that point, your odds to take away the hand improve dramatically.

You could get a better Ace to fold. Freeing up those 3 outs. 

No one has ever folded to the dreaded 'call'.  If you bet the flop and get called in both places, you still do not have proper odds to continue.  In a full ring game let this hand go.
