Castle Creations Phoenix 25 - 25A - 5 to 16 cells - BEC & Brake - Programmable cut-off
|Receiver / Battery||GWS Naro R-6N/H - 6ch - PPM - 35MHz - sub-micro|
|Servos||Ailerons - 2 x Ripmax SD-150|
|Elevator - Hitec HS-55|
|Rudder - Hitec HS-55|
|Static motor parameters||9.0A @ 10.5V giving 6600 rpm and 95W and \ approximately 90W/lb. Thrust_XL estimates the thrust as 496 g giving a weight ratio of slightly over 1:1. This seems correct as the model feels weightless when held pointing vertically up.|
|Flight performance||Climbs can be maintained at 45°+ or be more scale like at reduced throttle. Level flight can be maintained at well below 1/2 throttle travel. Loops can be completed from level flight and do not require full power to complete.|
10 Sep 06 - Whilst flying it Basingstoke MAC today the F4U spun in, completely out of control. Fortunately the model was completely unscathed and didn't actually hit the ground - it was sitting on top of the stubble in the field. Speaking to club members, this appears to be fairly common there when using the GWS Naro R-6N/H receiver. I think I'll replace the receiver with a longer range version before flying it again.
28 Mar 05 - Finally managed to test fly the Corsair. After a short ground run it climbed away at 45° with plenty of power in reserve. After throttling back to a cruise setting, the only trim change made was 1 click of up elevator. When throttled up the model rotates into a steady climb and is extremely stable in the air. Level flight can be maintained at well below 1/2 throttle travel. Loops can be completed from level flight and do not require full power to complete. The radio check was not quite as far as I would have like and I experienced a little interference at one point. Due to this I cut the flight short and landed after 2 mins 20 seconds. I will be moving the receiver further aft, away from the speed controller.
26 Feb 05 - Minor update of static motor parameters.
29 Jan 05 - Just finished and photographed the model.
