Wattage Pitts with Hacker Brushless Electric Motor
|
This is my Wattage Pitts. It is mostly stock except for the power system, two aileron servos and some right thrust added. It is a very nice looking model and flies well. The Pitts has a lot of drag and is not the lightest model by any means and because of this glides about like a bucket of hammers, but under power is a lot of fun!

Wattage Pitts Flight Log
|
May 5, 2004 - 6:30pm PST
|
Well, the wind was nice and calm this evening and based on the feedback I got on Ezone I didn't think I was going to fry anything so I rounded up the kids, packed up the digital video camera and off we went.
I was a little nervous as they are doing some construction in the lot behind my house and my usual runway is fenced off on three sides with a 6 foot chain-link fence. Worst case would be an abnormal departure from the runway, too late to throttle down, with a super strainer through the chain-link! Yikes!
As I expected the Pitts is very short coupled, but once the back wheel comes up it tracks pretty straight. I used the 9x6 APC for the first flight and with the Hacker B20 15 L Brushless Motor it provided good speed, but I think the 10x4.7 will be better for aerobatics. It needed a little down and some right aileron, but besides that flew pretty nice.
I trimmed it out and then brought it down to check everything out. Battery was only mildly warm, motor was warmer, but within limits. I agree with other comments on Ezone that the aileron response is very week. I took the opportunity to increase the aileron rates, and dumped a little of the differential.
Second flight was nice. A little rough on the takeoff, but over the fence and away.... Still not enough aileron for me so I think I will have to make adjustments to the control horns to get a little more.
I got about 12 minutes combined with the two flights fighting a little wind, which seemed to pick up right as I set the plane on the ground.
The Wattage Pitts would definitely be a much better flyer about 10 ounces lighter, but I am happy and this was a great change of pace from my Zagi which is all I have flown in the last two years.
I cannot imagine that this plane would fly well at the weight listed on the box (30-33 oz) with the Cobalt 400 included, so if you are considering it, don't.
I will take a look at the video my 10 year old shot and if I can edit anything out of it I will post a link.
