Went to the family farm this morning and ran 2 packs through the Racer, 2 packs with the Mini F22 and 2 with the Cub. Was a beautiful morning with practically no wind and I went to the far field which a much nicer spot to fly and land from. I brought my GoPro and recorded both Racer flights. Unfortunately my first flight the camera got knocked and was pointing to the side the whole time. First flight was with the 7x7 prop with a spinner on and when it came down the motor was 29 Celsius.
Second flight I ran the 7x8 prop and had a bit of trouble launching as the prop stalled. Second attempt was successful and when the plane came down the motor was about 36 Celsius. I'm not sure if the plane was much faster with the 7x8 and it probably used more battery. Flight time was almost 4 minutes with the 7x7 and about a minute less with the 7x8 prop. I probably flew at higher throttle settings with the 7x8 prop.
Overall I'm taking it easy still and not doing any aerobatics. Once I get the plane fully dialed in I'll play a bit with loops and inverted. currently the plane is pitching up a bit under high throttle/high speeds, which leads me to believe its more of a trim issue but perhaps a bit of down thrust will be needed. I'm also going to have turn the low rates down a bit, that will make me more comfortable with lower level high speed passes.
Well below is the video and most of the time the ground isn't in view to get a sense of the speed but there are a few shots. Hoping to get a chance sometime soon to measure time over distance to get a speed reading.
How fast do you think it is?
