Check out this cool video filmed by a spectator. I like his commentary and 4 Viper actions.

Thank you, Paul. It's fun to have all these Vipers chasing each other around. One challenge is that we all have different types of engines and throttle set ups. It's quite a challenge to fly in tight formation on the first try. We use 2 team formation: 1&2, 3&4. The guy with smallest engine stays in front. Viper (red/whitesilver)1 with JetCat 90rx piloted by Jose. Viper 2 (copper tone)with Jetcat120rx piloted by Dave Euse, Viper 3 (Ferrari) with JL T-12 piloted by Mike Lin and Viper 4 (Yellow/Green) with Jetcat120 piloted by George Manning. Each following jet will try to stay at the lead plane's 4-6 O'clock. It's easier to say than to do. Just doing laps was keeping all of us busy from start to finish. We did a couple of formation landings earlier and it's nicely executed by all pilots. The runway is really nice. Look forward to do that a few more. Now my engine has reached the service time so I need to take it out for maintenance.
Fun and reliable jet.
Mike.

There are no formal instructions from the factory, but we figure out by experimenting. The surge in pressure can be easily obtained by the handheld pump from Craftsman or any portal pump. It's a surge so most pump can handle it. I put 1/2 shock oil and 1/2 air it.

Victor, did you put the Viper in at Eglin?
I warned you not to fly it there if you did do it at Eglin
With a 10,000' runway at Santa Rosa why didn't you wait for the weather to clear and fly with us.....
Sorry that the bird is dead, I do have a few parts from my first Viper same color if you can rebuild it, your for no cost.

Hi guys. Just a question on the servo wires routing to the rear of the fuss. Mine is in a normal wire mesh sleeving. Cable tied away from the pipe itself all the way. Min of 20mm gap every where, in most places about 30mm. Should It be ok? Or do you all wrap it in heat resistance sleeving?

Hi Extra300s
Best way I have founf to run the wires is through/under the fin and keep them outside of the rear fuz, if you look back though this thread you will find a few pics of installs I made some time ago.
Update
"There is very little that has not been covered on the Viper within this thread if you care to look through it, for this particular question I would look at post #837 and #1244"

I finally have some good video of my JL Viper jet being flown on a bitterly cold winters day as you can judge by the headgear and gloves!
The engine is an old Simjet 3000 which is rather more thrust than the plane needs. Most flying by Dave was at half throttle.. It was the first flight on the engine which had recently been converted to kero start. The settings were not optimised and are much better now. Still is a great plane.

I agree with the others, the more I fly it the more I like it. Gorgeous, smooth looping maneuvers. More roll coupling than I like with rudder, but I'll get that mixed out when I have a bit more time to work with it. Slows down nicely (with crow), easy to land.

Guys, some advice please.
I ran off the runway this morning into the rough and bent the pin in the nose gear. I ended up removing the 2mm airlines to get the gear assembly out where I could work with it. It was a bit of a pain to straighten the pin, but I managed. The 2mm airline uses an external collar which appears to be pressed down over the tubing and fitting after the tubing is installed. I'm used to working with 3mm airline and the thread-on collars. I've tried several different methods but I can't get the collars installed tight against the fitting the way that JL installed it. Can anyone clue me into the technique?
Thanks for the help,
Greg

I have removed my gear before and was able to press the ring back in place with hemostats. It takes a little effort and be careful not to break the nipple. It will work.
Enjoy your Viper.
