-
- It will 'turn' but with great difficulty. A turn is really a combination
- of roll and pitch using the rudder first and elevator last. A rudder/elevator
- airplane with large dihedral will roll and yaw when rudder is used. With
- decresing dihedral comes decreasing roll capability.

- If it is a glow plug motor, about 10-15%. If it is a diesel, none.

- The screw on top of the head is the compression screw and that advances
- or retard the ignition. The adjustment at the carburetor adjusts fuel
- mixture in relation to air.

- Yes but at a lower rpm range. You would need a larger prop than a normal
- glow plug motor to absorb the power it generates.

-
- I don't know what Nbl or nbf stands for. If a 4ch radio is purchase
- with 3 servos, a forth can be added to receiver with no problem. A
- 4ch radio will come with a 4ch/function receiver. Servo reversing
- allows the flyer to reverse the rotation of the servo electronically.
- It's a nice feature to have. AM is more susceptible to interference
- and metallic noise than FM. They are not recommended in highly populated
- areas such as Los Angeles. My first radio was a 4 Channel AM Cirrus used
- in a glider. The extra two servos were never used.

- Yes, they have a rubber cone that mates with the spinner. There is
- a switch that is used to turn the starter which turns the engine
- over quickly. Soon as ignition occurs, the starter is removed.

-
- Yes, balsa is a lot easier to repair than foam/plastic. Foam/plastic are
- not necessarily stronger, just more convenient and saves time.
