Here's the second flight of my little Cub. This plane looks awesome and flies great! Thanks to Leigh for another great job on the sticks! In the maiden, we forgot to see how she behaved in a stall. We tried it this time and I'm happy to report that it didn't drop a wing, it just gently put her nose down.
Notes:
In the instruction manual, they recommend 80% aileron differential and no rudder mix. I found 80% was way too much and it made rolls very large and sloppy. I dialed it down to 50% (the same that I have in my DHC-2 Beaver) and it is much better. I might take it down a bit more as I slowly fine tune it.
The recommended elevator to flap mix was perfect. There was absolutely no ballooning when the flaps were deployed. I used a 1.5 second delay for the flaps.
All throws are set to the recommended high rate setting (or more) and it behaves very nicely.
To save weight, I went with the Power 25 setup instead of the Power 32. It was a good choice, the 25 has tons of power for this plane. I've read that many are using the 25 with floats and are very happy with the power.
As you can probably tell, I installed a set of 5" Kavan air filled tires on the Cub. They are awesome and only weigh 2.6 ounces compared to the 30 or 40 pounds or so that the 4 ½" Du-Bro's weigh that I have on my DCH-2 Beaver. (I have to keep making reference to the DHC-2 designation because it just doesn't sound right talking about my Beaver lol).
This little Cub has a split elevator design with each half getting its own control rod. To save weight, the halves have been joined and now function with just one control rod instead of two. Works great!
Before assembling this ARF, I read that a number of people complained about the stock tail wheel so I installed a Sullivan tail wheel assembly that works perfectly.
I had to get the Dremel out to do some surgery on the battery compartment to make it possible to fit some 4s 3300 mAh Turnigy batteries that I had and they now fit fine. Luckily, with the battery all the way forward, the COG is spot on.
In case you haven't guess by now, I'm really happy with this plane! It's a keeper.
