After the last failed test flight where I threw my propeller on my P-47 power upgrade, I secured the prop on more securely and headed out to try it out today. As my regular field is busy with Cinco de Mayo, I went to the soccer complex by the power station. Wires everywhere. But I took it up for a few circles of the field so I could see if it would perform - as I've made TONS of changes now from stock....
1. Upgrade to E-flite Power 25 870kv 600Watt motor
2. 60 Amp speed controller
3. 9.8"x6" 4-blade prop
4. Eagle A3 6-axis flight stabilizer gyroscope
5. 4s 2600 mAh 50C 14.8 Volt battery
6. Shimmed landing gear brackets forward to try to help on the nose-overs while taxiing
The flight was successful, but laaaawsie! - did it have power! As soon as I took off it seemed the plane was gone in the distance. I quickly learned to back off on the throttle on this setup. From there on I never went more than 1/2 throttle - and mostly less than 1/3 throttle. The power system seemed to hum along nicely with no complaints, though. I'll bet this plane would push 100 MPH if you opened it up.
With all the modifications from stock I've done now - and especially with the new 600 watt motor and 4-cell battery - there's a lot of weight added. Stock, this plane was around 45 ounces. Now it's 55 ounces. And add two for two Mobius cameras and it's up to around 57 ounces - over 3.5 pounds. And the wingspan on this plane is about 44" - so the wing loading now is pretty high. Which means the plane is going to fly pretty fast to maintain lift. And it did. But it still flew REALLY solid. Just faster. But what would one expect from putting a V-8 in a Volkswagon? <grin>
Anyhoo - here's the flight. Them con-fangled power lines got a LOT closer than I thought this time. With this bigger motor and extra power. the plane is a long ways away quickly it seems... And that over-turned trash barrel when landing - I'll swear, obstacles are magnets for my airplanes. HA! This plane will be a lot better at a more open field... Of course flying is easy - simply avoid the edges of the sky.... which includes objects protruding from the ground ;-)
