1.2. VMA-H240X Hornet 40-52 ARF ECS Sport Trainer+ - Fuel Tank - How to install

Question: How do I install the Fuel Tank into my VMAR Hornet 40-52ARF?

Answer: This is not difficult but the instruction book does not cover this directly.

Do the fuel tank setup first. Install the internal tubing and clunk(s). When the stopper has been tightened but not overtightened, install pieces of fuel tubing between or over the ends of the metal pipes to seal them against dirt and debris. Mark the back of the tank with an arrow pointing up so that you can clearly see which way the tank is to be positioned in the model.

Remove the black sealing gasket from the fuel tank. Apply sealant such as Pacer Dap-A-Goo to the front face of the tank around the neck and re-install the gasket. Apply more sealant to the front face of the gasket.

Insert the tank into the fuel tank compartment with the tubes forward and oriented so that the top of the tank is positioned correctly. Press the tank firmly against the back side of the firewall and secure in place while the sealant cures.

From the engine mount area, apply more sealant around the neck of the fuel tank working from the front of the fuselage.

When the sealant has dried, support the tank with sponge foam around the sides and bottom of the tank. You may wish to install your battery pack beneath or behind the tank before inserting the sponge foam.

1.3. VMA-H240X Hornet 40-52 ARF ECS Sport Trainer+ - Maximum Engine Size without modifying fuselage or engine mounts?

Question: What is the maximum engine size that can be mounted on the VMAR Hornet 40-52 ARF without modifying the fuselage or engine mounts?

Answer: The Maximum engine size is a .52 2 stroke or about a .70 four stroke provided that it will physically fit.

Better Answer: We can only endorse the use of engines up to .52 2 stroke in size or other engine types such as a 4 stroke having similar power.

The specifications on the engine mounts are as follows:


Engine Mount Engine Width Max: 1.3 in. (32 mm)
Engine Mount Engine Lug Length Max using Factory drilled holes: .7 in. (18.5 mm)

Engine Mount Engine Lug Length Max if using Custom drilled holes: 1.5 in. (39 mm)
Engine Mount T-Bar Beam Length Max: 2.9 in. (74 mm)

 

1.4. VMA-H240X Hornet 40-52 ARF ECS Sport Trainer+ - Servo Cavity for Aileron - Missing

Question: My VMAR Hornet ARF does not appear to have a cavity for the Aileron Servo. What should I do?

Answer: This is a manufacturing glitch that occurred on a few models produced in late 2006 and early 2007. The cavity is in fact there but the skin has not been trimmed away after covering.

This is easy to fix and takes about one minute per wing. Here is what to do:
 
  1. The cavity is to be 11 mm wide x 40 mm long in each wing. When the wings are joined, the cavity will be 22 mm wide x 40 mm long. This will accomodate major brand "standard" servos.
  2. Examine each wing root.
  3. The cavity is bounded at the front (towards leading edge of the wing) by the triangle stock adjacent to the wing spar joiner channel and bounded on the rear (towards the trailing edge of the wing) by a strip of "rail" hardwood. You can see the triangle stock and the rail strip from the wing roots. 
  4. Carefully cut away the balsa skin that lies over the cavity between the triangle stock and the rail strip. Each cut out will be approximately 11mm wide and 40 mm long.
  5. Test the cutout to ensure it will accomodate your standard servo. Trim to fit accordingly.
