I had a Razzle 3D, and here is my 2 cents.

Yes, it is a very cost effective 60 size ARF Fun Fly. But:

1. The Turtle deck is all balsa stick-build-up without a lot of hardwood to dissipate heavy loads of say a harrier landing when the wind drops from 10 mph to 0 in a second. I know of three other Razzle owners who broke the tail off, right behind the sheeting. (Where the ugly yellow begins). So, when I bought mine, I first removed all the covering from the fuselage. I epoxied four sticks of spruce into the tail section. Now, One dude did this by cutting out only the bottom covering and sliding them in there, but I wasn’t to fond of the color myself anyhow.

2. In removing the factory covering out of the box, I noticed several stingers where not glued in place very well. While the covering was off, I pumped quit a bit of CA in it before recovering. It was held together by it’s ultracoat.

3. Second, the tail wheel mounting plate, it a simple piece of 2” X .5” piece of light ply, white glues to balsa stingers. Mine broke off 3 times. I finally sheeted the aft enf of the tail, after the servo mounting area, and glued in a 4” piece of .125” ply in place to the stock plate. This worked a lot better.

4. Last but not lest, the I used tail bracing on the vertical and horizontal stabilizers. The improved rigid/strength quit a bit.

With these mod, I had not problems, and didn’t have to add any nose weight. I ran a MDS 78, with a 14X6 and 15X4W APC prop.
