Found this on Aussie ebay.  I'm assuming that Kenbrite were the Aussie manufacturers/agents for Cox stuff back then.  
The Electronic Sure Starter is really interesting.  Never seen one before.  Claims to be able to "burn off" a flooded glow head.  The unit contains a 9volt battery, so I'd be a little concerned about burning a head out.

I have one of those electronic starters. Never actually tried it. I guess I should take it out and finally use it. At least once.

I understand that, clear button heats the element continuosly with 1.5 Volts to burn excess fuel in engine. Three D cells are for this purpose.

One D cell is for heating element normally to start the engine. If engine flooded then clear button works as I described above.

9 V battery is for checking glow plug element electrical continuity and lighting the LED.

I don't have this starter, only I guess all of this information.

Cox Kenbrite brochure Empty I have a Kenbrite PT-19 box

Post  jmendoza on Mon Oct 14, 2019 3:45 pm

Have a decent Kenbrite PT-19 box if any of you collectors are interested, PM me with an offer.

Cox shipped molds for the PT-19 to Australia, sent packaging and completed engines w/ mount, wheels and prop. The blue plastic Kenbrite used is a shade lighter, as is the yellow. The PT-19 Boxes had stickers placed over the Cox Santa Ana address, and on the wing the mold was modified to say Kenbrite. I traded a Cox Seafire to a guy in Australia for his NIB Kenbrite PT-19.

Hey Jay.  Thanks.  It's nice to know a little bit of history about the Australian connection.  I knew they were made out here.  I remember the TV ads for the PT-19 and desperately wanted one, but we counldn't afford one and I ended up with a Testor P-40 instead- can't compare.
I found one used in box at a swap meet once but the guy had a couple of hundred bucks on it.  Still can't afford one 40 years later. Sad

I have one of those Electronic Sure Starters. I lifted the board out of it and took pictures. I'll have to dig those up.

As I recall, it uses 1.5v from the D cells to light the glow head, places 2 D cells in series for 3 volts to clear a flooded element, and the 9 volt battery is the rail supply for an op-amp comparator (I think it was a LM324?) used to determine when the plug is flooded. Only going off memory here.

I'll dig up those pictures and take a look at it again.

I got the PT-19 Kenbrite from a guy whose father owned a hobby shop in Sydney, and also was a distributor for Kenbrite. He told me it was a display model that his dad had at the store, it was never flown.

I still have my Cox electronic glow starter that I used in the '80s. Kraft made a glow starter equipped with an amp meter that attached to a square 1 1/2 volt square lantern style battery. When those batteries became hard to find I took the meter and installed it in my Cox starter. Worked great. It would indicate glow plug current draw. Nowadays I use a D cell powered glow driver that has an amp meter built in.
