I have envisioned a project to build a jet propelled 1/72 scale PT boat so approximate length of the model will be 13 inches long. The smallest jet drive unit I have found thus far is approximately 5 inches long and the output nozzle is .6 in in diameter. A bit large for the scale I'm considering. (I know PT boats did not have jet drives, but I want to utilize this type of propulsion) I'm looking for a smaller version of this type of drive:
Please let me know if there are any vendors that produce micro jet drive units, preferably with a brushless motor included.
Thanks,
MNS
