I am looking at putting a JetCat120 into my L39, but Skymaster mention in their "manual" that horns etc need to be increased if
other turbines than the Jetcat 80 is used.
What have others found, is it necessary to change the horns, and are there any other problems if the 120 is used?
Best wishes for 2010 to all jet drivers

Horns are fine for a 120.....

Cheers, Alex

. On the elevators i use like the ones for elerons and flaps..

I did the same thing as DelGato, the only horns that I change were the ones from the elevator for bigger ones like the ones use on the flap or ailerons, I'm sure you have visited this thread.

New project L-39

http://www.rcuniverse.com/forum/m_81..._1/key_/tm.htm

The Skymaster included horns are good for a P-120 installation. That is what we are using here on our BVM demo model and have had no issues at all. Just remember to keep those servo arms short.

same here, I am also building my SAkymaster L-39. P-120, and i feel very comfortable using the package that came with the kit.....

Thanks for all the comments and help.
My L39 is painted the same colours as the BVM demo, now to start putting it together.

Best wishes for 2010 to all
