Well I finally did it. After many post's on this forum, talking with numerous people including my instructor I just last week dropped the cash to get a complete trainer setup.

The setup I chose is as follows:

JR Max66 radio set
Boomerang 40 ARF trainer
Thunder Tiger Pro 46
flight box, starter etc

Each of these came highly recommended from here, my instructor and the hobby shop where got them.

I'm really happy with the setup and have nearly completed building it. I get the feeling however, that the boomerang 40 manual was written assuming that one has done all this before, especially when it comes to Propulsion and linkages. It is in these two areas where my questions abound.

Propulsion
1) The instruction manual says " use pieces of foam rubber to hold the (fuel) tank in place". What does this mean? Do I jam peices of foam down beside the fuel tank until there is no movement whatsoever? Do I somehow secure the tank so that it can't fall out?

2) The "vent" tube goes to the muffler for back pressure, the "Fuel Pickup" tube goes the the carb.....What does the "Fuel fill" line plug into? This isn't explained in either the boomerang manual or the engine manual.

3) The engine wasn't exactly a perfect fit onto the engine mount....Is this normal? Have a look at the picture...The manual does not mention anything about making sure the shaft of the engine is perfectly perpendicular the the thrust line of the fuselage. Does it look straight enough to you?

Linkages
1) The connection to the servo's is my main concern. The ARF kit included the linkages as shown. Two nuts, a brass cylinder and an Allen Key screw. Should the brass cylinder rotate freely? So that the pushrod never has any lateral bending on it.

2) The manual has a section on control throws. It's just a list of up and down numbers. How do I set control throws? Does this really matter?


The other thing which has really annoyed me is the fact that the manual switches between imperial and metric units at seemingly random points throughout.

Anyway...that's all I can think of at the moment ..Thanks for reading
