Manual says the top speed is 33mph for the T-16 which would be regulated by the governor. I still haven't found a correct Waltham speedometer and haven't installed a more common jeep type yet so don't know what my actual top speed is. Haven't gotten into fourth gear either way since I haven't been out in a field for a real run yet and am really limited in what I can do driving on my side lot and quarter mile of flat road in the housing area.
I do know from past experience with my jeep, that a long trip can be pretty rough on the passengers and the vehicle when you're trying to pedal at max speed on a hot day. Nothing like driving an open air vehicle without seatbelts doing 50mph on the highway with regular cars and trucks blowing past you on both sides going 80 plus mph. Only good thing is so far nobody has gotten angry at me being a rolling roadblock. They all seem to either smile and give a thumbs up

or look concerned when they see me in WWII Denison with the weapons mounted on the side and hood
No problem doing a spread of shots for you. That way you can pick and choose based on allocated space. Once it's all done, I'll also set something up so I can take some photographs from overhead in a similar way to the 4.2" Mortar Carrier shots the Canadian's did for their prototype T-16s.
