I believe the Engine is 25mm. If that's the case it wouldn't fit
From what I've read, some 23mm will work, but others bump into the battery cap or at least scrape into it. I think it's because some tanks stick out a little over the 23mm baseFrom the reviews that I saw and some feedback from friends, It seems very good, but officially, the Pico only accepts 22mm tanks...
Sorry, I meant the Engine Mini which is 23 mm. I corrected my post. Thanks for pointing it out.I believe the Engine is 25mm. If that's the case it wouldn't fit
