TOPIC: 'Top-Jet' Rocket motors for Model Aeroplanes

Hi guys,

is there anyone out there who knows anything about the 'Top-Jet' motors? By all accounts they are very similar to Rapier motors and, similarly, made in the Czech Republic.

I've had a query asking about them, and I had to confess I had not heard of them
The motors my colleague had come across were nicely engineered and a bit larger than Rapier L-2 motors, more in L-3 territory with similar performance, i.e. a steady 400 mN for 18 sec. Below are two data sheets:





Note there is a range of motors - fall of them very desirable:


There appear to be equivalents to the Rapier L-1 (80 mN) Rapier L-2 (120-200 mN) and L-3.

This is the only info I have - I don't know if they are still made, or whether they were ever available 'over the counter'.

So, if anybody knows anything at all about these motors, please tell me!

So these are from Svinčany, 535 01, Czech, which is less than ten miles from Pardubice. I wonder if these are somehow connected to our friend Dr Z?

Hi Terry,

if you can find out anything about these motors I would be most interested ....
