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 :blush:
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!:cheer:
