One of the two props that come with the Zipperis already screwed onto the prop shaft (above left). The freshly painted foam spinners (above center) could use a bit of the tacky adhesive used for model railroad grass scenery to stay secure.

thirds throttle. About the only thing it really couldn’t do were stall turns since there is no rudder.
There weren’t any surprises with the P-51 either. That very nice 4-bladed prop pulled it off the ground with plenty of authority in a short distance. Because it is 4-channel, it comes set up with a steerable tail wheel. That’s a very nice touch for a plane this size and helped the ground tracking quite a bit. In the air the P-51 showed that it had plenty of pep but still could slow down nice- ly. It did need some trim for both elevator
and aileron but it wasn’t much and almost right away Thayer had the plane weaving between and around some trees in the park to set up for photo passes. Once again the battery, even though it was only 800 mAh instead of the specified 1000 mAh, provided a decent 9-minute flight with reserves. Pretty much the same maneuver regimen was used with the P-51 as the Zipper. And as with the Zipper much of the flight was far below full throttle. Have to say that the plug-in main gear will allow removal for hand launch flights so that the planes flies
with “gear up”. That gear is pretty robust and with decent size wheels will definitely handle grass fields.
There’s a lot of complimentary things to be said about both planes. Either one can provide some good solid flying that isn’t quite the very casual Sunday flier fare but also isn’t white knuckle anxiety. Both are more middle of the road for any R/C pilot with some experience. They’re economical, and they’re ready for flight real quick. So, have a weekend to spare? Here are two good choices to make it a very enjoyable one.
Plastic model spray enamel worked fine for the red and the blue paint on the Zipper (above left), and without it the plane would have disappeared in flight

(above right), especially with the pervasive snow cover and the hazy sky. Despite its racy appearance the Zipper is a pretty nice sport flier.
