A little video I made of Sunday's flying session. I was assisted by a friend, his wife and his young daughter who can be heard enthusing in the background.

Looks like you were having a lot of fun here Terry. Good to see the Skyray performing again, must fly mine sometime too. I was pleased to note at Old Warden that the Tendera motors are quieter than Rapiers and more like the old Jetex motors.

Thank you Terry. The flight of the Skray was just outstanding, and I put the usable motor time at around 17-18 seconds.

These TSP L-2s are obviously quite powerful - did you try 'bored out' L-2 or one of the '150mN thrust motors with the Skray?

Terry has just measured the thrust of the latest batches of L-2 motors with the following results:



Terry adds:
The green trace is the July batch; red and grey are deliveries of Sept 7th and 8th respectively (a very nice 150 mN ).
Orange is the Sept 16th pickup.

As I've remarked before, we can plan our 'winter bulding program' with confidence we have the wherewithal to power our models!

Hi Tony,

a timely request. Terry has measured the latest batch of TSP L-3 motors from Piotr with the following results:



These look to be a very viable product. :)

I have to say these L3s are very nice motors. Of the small initial batch that Piotr has produced every firing has been easily accomplished with the thrust quickly steading and no sign of burn through on the 15mm diameter motors.

I just took one out for an air test on a 290mm span Depron [ :woohoo: ] and balsa T33. Weighs in at 40gms and got a very nice flight out of it.

Roger adds:

did you mean your latest T-38?



Very encouraging!
