Hi like to know what you think about a u can do 3d 60 size for a second plane..thanks chad...

This may go against the grain.... But if your proficient with your trainer
and have tried a tail dragger and can land good...
I would say on low rates and a forward CG the UCD 46 can be a Great
second plane... It flies super easy, No bad habits, lands really easy,
more so with the forward CG.. It's a floater and cheaper to buy....
It does not like hard landings, will rip the gear out if you do not reinforce.
And being a 3d plane it is built light, So landing other than on it's wheels :-)
will break it..... There are better steps to take first... But I would do it
if I had to do it over... My UCD 46/YS63 is the easiest plane I have flown..
But that's just my opinion

My UCD 60 had the widest flight envelope of any model I've ever owned. Its extreme lightness allowed it to basically stop and mid-air and not stall right away. I could "walk it down the runway", IOW, walk alongside of it while keeping the nose up, about halfway between a hover and flying a straight line. An accomplished 3D pilot can do amazing things with one. Yet, my young grandson had no trouble flying it during his formative period (fresh off the buddy box/trainer).

But there is no free lunch. The UCD airframes are rather fragile, and will not take much abuse, such as hard landings, etc. That is not to say they are short-lived; I've seen one that was flown until it was basically falling apart, but it took three years of being flown almost every week-end to get there. Just keep the landings gentle...

So, if you are comfortable and COMPETENT with a trainer, a UCD will not throw you any curves. Just be aware that it will do things you might not be ready for. The way to avoid that is to keep the control throws at or below the minimum listed in the manual. As you become comfortable with the UCD, gradually increase the throws to your taste.

And don't overpower it. A .91 four stroke or .61 two-stroke is plenty for this airplane. Just be aware that an inverted installation will require some sort of pump or regulator with most engines, due to the tank being well above the carburetor. Contrary to some opinions, a side-mounted engine is absolutely no problem on this airplane. Mine had a side-mounted YS 91 FZ, which was WAY more power than needed for normal flying.

The UCD has been a very popular model; IIRC, the only model that has had a longer-running thread here on RCU during the height of its popularity has been the EF Yak, and possibly the H9 Funtana 90. Dig up that old UCD thread; it will keep you busy reading for hours...

I went from a LT-40 to a U-CAN-DO 40 size. In higher winds this thing can be tricky to land and I have knocked the landing gear off a couple times unfortunatly. If your proficent with the trainer I would say go for it with low rates initially.

Got to go with the flow, this thing is a 3D trainer and on low rates, could almost be used as a trainer. Just make sure you put enough power on it. It is a large airplane for a standard .46. If you use a OS, TT, or Magnum .46 to .52, strongly suggest you spend the $15 for a Tower .46 muffler. It is not only lighter than stock, it makes those engines run like they are on steroids. Also, if you are using std servos on the ailerons and rudder, make sure you go to 6 volts for the extra holding power, torque and speed that will generate.

Be warned, the airplane has a inherent weak fuse above the landing gear and it comes off easy. Once it does come off and it will if you fly it off rough grass, glue it back with good 30 minute epoxy extra pins through the formers, extra tri-stock and fiberglass cloth over the outside for extra strength. I have one that is over two years old and after that fix has survived many rough landings.

One other thing, you really need a good computer radio with expo on it to get into really wild aerobatics with this plane. It can be flown on a standard radio on low rates, but will lack what it was made for.

Good luck, and welcome to the world of 3D capability.
