<span style="font-family: Verdana;"><font size="2">My Ultimate 40 was RTF at 90oz (5.6lbs) including the 18oz Lithium pack. I measured 60amps static current (or 1300 watts) with my AXI 4120/14 using an APC 11x7 e-prop. My 6-cell </font><font size="2">FlightPower EON28</font><font size="2"> 3350mAh 28C pack can deliver 94amps continuous so it will not be getting stressed. My power to weight ratio was 1300w/5.5lbs = 232w/lb.</font>

The Ultimate 40 flew very well and </span><font face="Verdana, Arial, Helvetica, sans-serif" size="2">the AXI 4120 provided</font><span style="font-family: Verdana;"> enough power to knife edge at half-throttle. Full throttle was rarely used. We flew several flights with mixed aerobatics for around 7 minutes each. The only issue we had was with my old FMA digital servos lagging behind the pilot elevator control. Iwill replace them with new JR DS-821 digital servos.

</span><font face="Verdana, Arial, Helvetica, sans-serif" size="2">We saw no bad tendencies in flight and landings were relatively easy.</font> <font face="Verdana, Arial, Helvetica, sans-serif" size="2">The video of the Ultimate is with 10-15mph winds. We had plenty of power and the wind didn't really affect the flight. The combination smaller prop on a 6s Lithium pack really makes the Ultimate 40 nice and fast. As you can see in the video, my Ultimate 40 tore up the sky!

</font><font face="Verdana, Arial, Helvetica, sans-serif" size="2">The Ultimate design is known as a "Muscle Bipe" because of its extreme aerobatic capability. They fly fast and land hot. The smaller span models under a 40" wingspan are the most difficult to handle usually due to high wingloading. In recent years, lighter construction techniques have allowed the 40" span bipes to become less of a handful to fly and land. The Wings Maker Ultimate 40 design is in this new category.</font>

<font face="Verdana, Arial, Helvetica, sans-serif" size="2">Only intermediate flying skills are needed to handle this bipe as it is designed to fly very well and land slower with some low power required until touchdown. The key to a good flying aerobatic bipe is to have proper incidences and sufficient power. The Wings Maker light ARF design and incidence guides make the task a whole lot easier.</font>

<font face="Verdana, Arial, Helvetica, sans-serif" size="2">Although a .40-size glow engine will provide sufficient power, a .50-size engine makes the Ultimate 40S very spirited! For a glow-to-electric conversion, having around 200 watts per pound provides great performance that is both clean and quiet. A motor in the 1000+ watt power class is recommended.
