Hi, I also fly ate 600 mt above sea level. My landing flap is about 65º-70º and I use about 5 mm crow with elevator mix (about 2 mm up elevator) only for landing flap. I have a Jet Central Cheetah 160. For landing, on upwind I lower the gear, when it is down I go to take off flap ,and once in downwind go to landing flaps between 1/4 and half throttle depending on wind. On final I keep the throttle at about 1/4 managing altitude with throttle so that it touches down a little past me. When I know I have reached the runway I go to Idle, usually at about 2 mt altitude. Some time we have a lot of wind and to bring it in throttle on final has to be more, it slows almost to a crawl with no bad habits.

Regards
Eduardo

If you have 2mm UP mixed with flap you are running nose heavy.
The Viper’s huge tail hides this situation well, it’s why people have been flying this aeroplane nose heavy since it was designed.

Hi Guys,

Very helpful tread, thanks for that! Just a quick question, what size pilot will fit this plane?

Thanks,
Hans

I have 1/4 scale pilot from warbirdpilots.com The pilot is 15" tall and fits just fine in my Viper.

Near 10 year old CARF Viper brought up to date. It was in quite a state when it came to me for a running issue. Cleaned and polished, new canopy, totally ripped out and re wired with Powerbox wire, Mercury fitted, changed to Core. Fuel system was rebuilt and turbine serviced at JetCat. Ready for another 10 years!

Yep…probably don’t even need to be on the airfield 🙂 Set up correctly they are just like flying a leather arm chair. The owner will be shocked when he next flies it as I moved around 12oz of batteries from the nose and put them by the fuel tank! It flies even better with a correct balance.

Bob, no CARF Viper’s are all 2.6m

Default Help with Unilight installation

Can anyone help with spar position in the wing please and how you routed the cable? I’d like to install Unilight nav/strobe units on the ends of the wings but I noticed the wing is sealed outboard of the aileron servo. I also want to make sure I’m either in front or behind the spar when I cut a slot in the wingtip. Any help would be appreciated.

Love it when you skid around the corner with the rudder on the slow passes!

There was a cross wind that day from memory, but slow turns with a jet is all about the rudder…it’s why so many run into trouble trying to fly slow, they just use aileron!

Wondering if anyone has or can take a pic of their Electron nose gear/servo/linkage setup? I pulled my ER-40's from a Carf Hawk and contacted Electron as to what needed to be changed for this Viper and received the parts. For the nose gear, all that Adrian from Electron said needed to be changed was the servo mount which is offset to lower the servo. Even with that I have to mount the servo from below the mount(not pass the servo body through the mount) for the servo arm and linkage to clear the fuse skin and it's still very close. Just curious if I'm missing something mechanically. Thanks.
