TOPIC: New Motors from TSP Modelar

Not exactly

We now have a new TSP L-3 motor, which is looking very good:



So we can now build the larger 'Flying Scale', or even Tailored, models and duration models with confidence we have the means to power them. More about these motors - availability, prices, etc. later.

Piotr is now producing L4 motors and these are very nice.

Weighing in at 28gms fully charged and in 18mm x 66mm tubes with an average thrust of 850mN (87gm or 3oz in old money) for 20 seconds. They follow the same general design as the smaller motors and ignite easily and fire smoothly. In fact with a slightly larger exhaust I was able to see some very pretty supersonic shock 'diamonds' in the exhaust. (although this is not seen in my video, I need a better camera!)



I can see these being just the ticket for larger models and even, dare I say it, radio control.

These look very nice indeed - there are some classic large duration models, like the 'Vindsvreen Viper' which would go very well with this motor. Add (say) rudder and elevator, and you have a great model for some small field thermal soaring. Even I could be tempted!

Also, a tethered car:



Above: this early Wilmot Mansour car (1948) was originally (I think) Jetex 350 powered

or hydroplane :






Above: Jim Free (now sadly passed away) powered his Hydrojet with a Rapier L-3. How he would have loved the new TSP L-4!

Terry has posted a splendid video of his Skyray on You Tube:

Good stuff!

Excellent, way to go.
