shooter,

I have the zoom zoom set up now on the 2212/34 and 3s1p tp 1320, plenty of power, weighed in at 14.5 oz. with 2 bluebird 371 aileron servos (4 servos total) a hitec electron 6, and phoenix 25. good for outdoor, or if your good, probably indoor 3D. seems to be a nice flyer so far, I'm just starting to trim it out. I think I'm going to try a phoenix 10, and a smaller pack to lighten it up, then it should be even better, maybe about 13 to 13 1/2 oz....... good plane for hovering for sure.

hope this helps,

wood

Hi Guys,

I just maidened the ZZ 4D yesterday! I was VERY pleased with it. AXI 2212/34, Hokam 1500 3 cell, and TP 1320 3Cell. 10x4.7 prop. There was plenty of power. However, I've read other reviews where the AXI 2212/26 has more "punch-out" of hover power. The plane flys nice, and displays more of the "floater" tendancy during landing than other foamies I've seen. The plane rolls very well, and does not have too bad of roll-pitch coupling with rudder. For CG, start with the battery pack around on top of the wing, near the LE. This plane seems easy to hover, point rolls nice, and floats in on landing!!

Hi Guys,
Flew the ZZ4D some more last night and moved the CG aft. The battery is velcroed on top of the wing, in the center of the wing. In this position, the cg is such that is barely dives towards mother earth when inverted. With the CG in this position, the rudder has become nice, and knife-edge loops are now possible. Also, I've settled on 7% "up-elevator" mix to Left and Right rudder, and 5% opposite aileron to rudder. Thus far, I'm very pleased with the "flying" capabilities of the plane. However, I do wish for maybe 10% more power. The TP 1320 cell (I think), definately outperfoms the Kokam 1500 3cell. I ordered some 3cell 900 packs to see if the lighter weight will help, and a 11.47 instead of the 10.47 prop for the AXI 2212/34.

Thanks,
Jim

HI All, this afternoon I added a 3/16" carbon tube I had on hand. I glued this carbon tube down the side of the fuselage from the motor to the horizontal stab. The result is a VERY STIFF airframe. I flew it again in about 15-20 + gusting conditions, and the plane was just rock solid. This spar made a tremendous difference in the way it flew, and the extra 0.3 oz or so made no difference in vertical performance. If I had to do this again, I would also add this type of spar to the wing, which with just the incorporation of a carbon 0.07 rod, still flexs a little in pull-outs and with gusts. Basically, this type of spar-age gives the still bouncable EPP frame, the stiffness of a wood built-up structure.

Hi Guys,

Two more mods to the ZZ4D. I added s section of 0.07 carbon rod to the underside of the counterballanced elevators, so that the counterballance could not flex differently that the main portio nof the elevators, and added a section of the rod to the rudder. Now I believe, any of the play is left to the servo train.

I also flew with the 900 mah 3-cell Kokam 15C rated batteries! These seem to offer more "punch" than the TP 1320s, or 1 year old Kokan 1500 3Cell that I have.

Thanks,
Jim W.
