When you open the Venture box you are presented with a project that should require less than 5 hours to have in the air. The entire frame set is built, including the control system and head with all linkage rods installed. The tail boom requires simply twisting the end of the tail drive installed belt and looping it over the tail drive gear, then tension the belt and tighten the boom holder and the single boom support rod. The fuel tank is installed and ready to hook up to your engine or header tank. The landing gear struts (installed) are attached with rubber "lord" type mounts, which should help prevent frame damage in an "incident." The installed cooling shroud is strangely distant from the top of the engine head but much better at directing air than the Raptor v1 or original Sceadu. I had no cooling problems. The clutch and start system is similar to other JR helicopters but is a new style. The flywheel is relieved for the clutch shoes similar to the Kalt 30 Baron and it can be installed in two directions to minimize runout. The instructions explain how to check this, and our sample had significant runout with the clutch installed one way and virtually none when I rotated it 180 degrees. Two 3mm bolts (with threadlock) hold the clutch to the flywheel. The clutch has a one way bearing so any 6mm hex start shaft extension will work to start the Venture. |
The kit comes with wood 550mm blades and 4mm mounting bolts. It also includes two flybar setups the installed setup is for beginners and is a pretty stable arrangement. An optional flybar and KSJ style paddles increases the responsiveness considerably, at the expense of a bit of pitchiness as is usual with the KSJ paddles. We have flown the Venture quite a bit. With the mild flybar setup it is a very stable machine. Any beginner will be happy with the feel. Due to the JR trademark large fuel tank mounted far forward of the main mast, the fore-and-aft trim will change during the flight as the fuel burns. (Much more so than on the Raptor). The mild setup is somewhat deader than the stock Raptor 30. With the Venture's hot flybar selection it is nearly as agile as a Raptor, though definitely suffering from some pitch sensitivity in forward flight and some overall slop in the head. Dulling the leading edge of the paddles normally helps this problem. Although the performance is not QUITE as good as teh raptor V2 or Sceadu for 3D work, the Venture is a VERY GOOD trainer and sport heli and is the LOWEST cost option we have. |

New style tail case is pre-assembled as shown. Looks a bit nicer and neater than the old Ergo 30 style. |
 |
Frame set is molded with integral bearing cases (as per the Raptor, Sceadu, etc). Molded extrusion on lower frame makes it VERY rigid. Also note the dampners on the landing struts. The Cooling shroud seems optimized for a 50, but works fine. Tank is front mounted. |
