Got a bunch of good flights on it this evening. Played with 4 different props and came back to the 15x4 Xoar. Will probably try one or two more. I am getting 9200 RPM on the ground and a little over 10k in the air which works out to a little under 10lbs of thrust. At the moment the plane weights 6 pounds 5 ounces dry, but I have not put the cowling on yet. I weighed a 60 Extra EXP with the battery in it and it came out to 5lbs 11oz so the gasser is basically 1 pound heavier than the electric. I can probably get more speed in the end out this setup, but it does not have the explosive pull out the electric has.
The Xoar 14x4 had electric instant response, but it hit the speed barrier pretty quickly.
Xoar 15x5 lost 1k RPMs in the air for basically no more speed.
APC 14x4W was pretty similar to the 15x4 in feel and performance. I would rather have the bigger prop disk.
I want to try an APC 15x4W and Xoar 16x4 when I can get my hands on one.
I forgot the hatcam, sorry.
I was able to get stable hovers and harriers. The only weird fly habit it has is that with the battery in the tail, it does not do very good waterfalls because it runs out of pitch authority to throw that extra weight around against all the weight in the front with the engine.
I am easily looking at 14-15 minute flight times based on the current fuel consumption.
I am heading to the FLI for the weekend so it will be next week till I can put some flights on it. I will probably wait till I get the cowling done up. It needs some work as I had to cut out the entire bottom for it to work. I bought a backup cowl just in case.
