THUNDER TIGER TTR4572 Assembly Manual page 18

For satisfying 3D performance and safe sake please read the following
guidelines before you fly your 3D Spirit.
Do not install engine over .50 cu.in. as it is overpowerful for this plane.
Normally a Thunder Tiger 46 could hover the 3D Spirit at its 70% output
power.
Recommend using 11x4.5 or 12x4 propeller, smaller pitch is preferred.
Always set low rate as manual instructed for the first flight or taking off
until you fine tune your plane.
Since 3D plane is light weight structured and fantastic low/middle speed
maneuverability, never intend to fly your 3D Spirit at full throttle or high
speed
Use care to check all control surfaces and linkage before each flight. Do
not take chances to fly the plane if there is any problem.
