The Scorpions are great jets and are easy to land. With the right gear will handle grass no problem. Looks like the new manufacturing has fixed a lot of the quality issues from when I had mine. Compared to the Elan, I would say the Elan is faster and more aerobatic (the Scorpions are slow unless you put a big block in it).

I like the the suggestions for the JL Viper - nothing but positive stuff coming out of people who fly those.

the UF's are great airframes and probably the toughest out there. If you're looking for something with a really wide speed envelope they're hard to beat.

Oh yeah, definitely look at used if you go the UF. Or a Classic Flash. There are so many out there and they pop up for sale often. One of my flying buddies got a CF last year for 4500 ready to fly with a jet Cat 140Rx. He has put tons of flights on it now.

I have both, CARF Ultraflash and Skymaster Viper 2.6m viperjet
The UF was my first ever turbine plane and I got my waiver with it. Set up correctly and having an excellent coach that has flown an UF is what it takes. I love my UF...but the Viperjet is actually, though its bigger is more relaxing.

What kind of waiver do you need to fly RC jets?

Terry Holston

My Feedback: (1)

AMA Waiver to fly TURBINE powered jets in the USA at an AMA field or event. If you have enough room on your own property and are not afraid of anything happening to others then you don't need a waiver.

A friend started with a viper with a jetcat p90 (supposedly more thrust than a 100). it would NOT take off of 800 feet of the best maintained, putting green maintained grass in the northwest. He was forced to take off on the road and land on the grass. After 5-6 flights it experienced a weird departure and pancaked at low speed. I think the wing failed structurally-most likely the skins delaminating from the spar. He replaced it with a carf ultraflash. It wont get off the grass either with the p90. Carf tutor with a 180-Takes off and lands in about 250 feet on the same grass..

This does not sound like Jet Legend Viperjet. We have had several different JL Viperjets fly off grass at Raydon. The engines have varied from VT80 to Merlin 140. None had any problems getting off. If a plane will not take off in such a long distance indicates it was far too nose heavy.

John it wasnt nose heavy and it wouldnt take off. It was a jet legend viperjet. The flash wont take off there either. The grass is well maintained and very short on the runway. Maybe it would go with a 120 or larger turbine.

How much did this Viper weigh and what size wheels were they?

My Feedback: (10)

Viper was built with no mods and had the as big of wheels that would fit without hacking it up. Nothing extra added. Built by an excellent modeler and flyer. The grass there is draggy. The flash wont take off either. The moral of the story is that if you want to reliably fly off of grass with either plane is that a 100 class turbine wont cut it. A carf tutor with a 160 and the recommended behotec trailing link gear/wheels gets off in 250 feet every time... Ask Andy Kane why he got rid of his other jets but kept the tutor. Its because it will get in and out of just about any field capable of landing a 40 sized glow trainer.. If i wanted a pointy nosed sport jet i would get an ultra lightning with a 180 or larger in it. The wing loading is way down from the flash/viper and the bigger wheels would work better on more grass fields. The flash is a nice flyer and it is amazing how slow it will fly. And the viper flew well right up to the point that it started porpoising and crashed. There have been a few complaints about carf not getting the horns glued in straight etc. but you don't see any mysterious crashes or suspected structural failures with carf. And none of the typical "oh the factory in china got it right this time. We promise. Just send the money...."
i would bump quality up a couple of notches on your scale. I would buy a used bvm or carf before a new composite china model. The pilot sport jet looks promising but i would want to see how well they hold up after a couple seasons of flying.

Your friend must have some serious problems with his engine not developing full power and/or he has the planes very nose heavy or your grass needs cutting! Here is some video taken at random from the Internet of JL Viperjets and Flashes taking off grass with 100 size engines.

Viperjets aren't "sport" jets last I checked.

For toughness, I mean flying tanks, CARF flashes can't be beat. My classic flash took some serious beatings, multiple dead sticks (from all the Hillclimbin with Doug ), landing off the runway, gear up and gear down, other people hitting the gear switch, etc....

And well, it is one tough mudder. Almost literally.

All that said, I love bandits! Nothing flies like a bandit, but they are more delicate and more expensive.

I don't see how the UF would struggle to get off that strip with a 90N engine, mines only got a Merlin 100, if the CG is right, it should easily rotate within 80 - 100 yards, mine is on the Tail Heavy side at 240mm and it rotates within half of our 200 yard mown out strip and it's cut short but not putting green standard.

I think the two main things you should consider is ........how much you'd like to spend?? The Jet Legend Viper is an amazing airframe for the cost, and does fly very very well and lands quite slowly aswell, the Ultra has the edge on just about everything but your gonna pay nearly twice the price for it. We've got both these jets (my Ultra Flash and my Dad owns both an UF and a Viper, he often leaves his Flash at home as he says he finds the Viper much more relaxing to fly).

The second for me would be......do you think you'll outgrow the Viper quite quickly?? If I your eventually looking to move into something like a Flash then I would just take the plunge now as you will not be disappointed, for me, it is pound for pound, best sports jet available today. I've not owned many jets (4 so far) but quite a few friends have got some high end toys so I do get regular go's with what they have, and I'd still take the Ultra (flying wise) over everything else I've flown.

Hope this helps.

Hi john thanks for the videos. We will have to measure the thrust on the turbine and see what it is actually putting out. It is hitting about 180-190 mph on the gps but you never know till you put a scale on it to see how hard it is pushing at a stop. On asphalt his will get off in 200 feet or so.. So i would bet it is fine but you never know. Those guys had the grass cut pretty short in the videos.

My guess is that the plane has a nose down attitude. Ideally it should sit with a couple degrees of nose up attitude for proper take off. It's much more critical on grass than pavement.
