In short-yes! look at:
www.texastimers.com and see under 'micro' timer-this is based on a Tomy clock mechanism. There is also the 2-function texas mini. Alternatively check out:
www.freeflightsupplies.co.uk and again look under timers. Mike Woodhouse sells a Tomy based micro shutoff timer with a different type of arm to Texas timers. I have several of each and can recommend them. Both-with a bit of fiddling-can be setup to add a temporary quick DT function for trimming purposes.
Some figures: Texas Micro-1 weight 6.4g max ER time ~25secs
Texas Mini weight 15.4g max ER time ~17 secs
W'house mini-timr weight: 5.9g max ER time ~30 secs
Tatone 1/2A tickoff wt:16.7g max ER time ~15 secs
All these weights and times from my own examples, and static running free (ie no effects from engine running vibration or fuel line drag). Though they do an equivalent job, the Texas and Woodhouse timers use their clock mechanisms differently, the Texas runs unslowed, the Woodhouse has the waggler slowed with weights, shown in the photo.
