Do you feel the need for speed? The Hobbyking Viperjet is a true, fully aerobatic speed machine with stunning good looks to match it's performance. The 70mm version has been a massive hit and rightly so, this amazing 90mm version is sure to be just as popular. The bare airframe is lightweight, so anything from 6s up is going to give you an amazingly cheap 90mm sport jet, certainly nothing in this class looks this good and fly's so well for so little money.
The Viperjet's superbly painted composite fuselage and matching pre-applied covering make for one good looking model, combine it's looks & speed with the Viperjets amazing precision aerobatic ability and you have one of the most exciting EDF jet's in it's class at a price you can afford. This gorgeous looking model is also well behaved at lower speed courtesy of the pre-installed split flaps and of course the "winglets" which provide lift, right down to the slowest of speeds, meaning a greatly reduced stall speed and excellent flying manners.
A full hard-ware kit and fixed landing gear are included, retracts can be installed of course with a little work. The large canopy area gives you plenty of options for Lipoly batteries, ranging from 6s right up to 10s for the real speed freaks!

Pro: Plane looks awesome. Plane flies well. Split flaps work well. Access hatches are well designed for both EDF and battery. Plane is fully ducted from factory.
Con: Major-When they assemble this plane at the factory both of the planes I purchased have the vertical stabilizer lean to the left about 1/4".=Factory defect that cant be fixed, this is the reason for 3 stars on quality. Other Minor-Both planes also had the elevator covers rotated 90 degress so the decal on the cover had to be removed. Minor- The position of the internal wall for the front landing gear severely limits the gear height.Plane came packed nicely; however, several minor paint chips on the fuselage nose area. It also appears the finish has been scuffed in places as the sheen has dulled. Very poor overall finish. Additionally, the two piece exhaust ducting is a welcomed innovation but there appears to be no room to extend the servo leads from the rudder and elevators forward thru the fuselage. Can anyone provide a "work around" for this problem? Would also like specific retract recommendations for the model.had a few scratches out the box nothing major. flies great . im running 10s jetfan. very nice starter jet after flying a few foamies. i love it !!Got the Plane
there was a scratch in the side through the paint stripe
also was a soft spot on the same side this is why the lower rating
no real problem added a little epoxy to stiffen but for the price and cost of shipping
The consumer should not have to do even a miner repair seemed to be well packed so has to be a factory quality control problem
other than that plane looks great seems to be balanced going to use Doctor,.
Mad 6S 90 EDF also bought retracts to add to the plane should be nice when doneFlying this jet on jetfan 90mm with het 1680kv on 8s , pulling 119.5 amps and 3650 watts , I epoxied all the formers and retract area. Keep it lite , mines 8 lbs 11 ozs. Cg 98-100mm from le. Just got the 120mm edf version 2100mm wing span. Eflite 15-25 retracts with tams trunnions and struts, drop in fit !Way better than the first batch .
Flies great at 100mm cg and good power from jetfan 90 and het 1680 on 8s. Retracts are possible , look at tamjets and eflite 15-25 size. I did reinforce all the formers that I could get to with more epoxy and strengthened the retract mounts . Duct work for the fan is top notch and paint is good. Dont let others bad luck with this jet discourage you from making a good purchase and flying a fun plane.
Will tip stall if speed is to slow coming in on approach.received my viper jet with a 3 mm crack about 5 inches long straight up the leading edge of the vertical stab.looks just like it was not joined correct. when the 2 fuselage half's were joined together as one fuselage. Little disappointed since I have been waiting for a year for this jet to be in stock. Will try and repair It with stuff it Fiberglass and try and match the green paint .Just received mine, looks Great! Will start the build next week.
