Yes its second hand and only worth half its original cost.

Okay, $2,000 to build + $2,000 parts, YOU can have it at 1/2 or wait til someone builds you one for 1/2 the price of the components.

Flew mine yesterday - P160 (I know, but i dont have a 120

Take off roll very short, rotation hardly noticeable. Very smooth.

Flap - have set up crow - about 5mm up on the ailerons at full flap, and hardly any pitch change. Landed a bit fast so bounced and got airborne, but no bad vices it seems.

Love this jet

One comment - on the tail feathers - a bit of silicone sealant between the fin / stabs and the fuse before you bolt them in stops any wobble and helps with flutter.

Have fun guys - lovely jet!

A guy is selling one of these part bulit for £1290 including retracts/lights/wing bags.
Is it a good jet?

Difficult one to answer - I think you could buy it from a dealer att that price.

I got really lucky - paid 600 for airframe incl retracts and 7 servoes.

I would guess 8-1100 is what I would expect to pay.

Always the option of an F15 if you are getting into jets - they are great.

But to answer your question "is it a good jet" I would (after only the test flight) have to say yes, definitely

Blimey,£600 is a real bargain.I take it that was second hand?

hymie42

Nope - yesterday was the first day it flew. Was in someones loft for a few years first though.

So.... you going to buy it?

I`m seriously thinking of making an offer for it.It will only be my second Jet as I`ve just started out with the Boomerang Sprint,idea being to use the P80 plus all the bits from this jet.Isn`t a P160 a bit over powering?I was looking at the Skymaster Viper jet 2m WHICH IS £2300 from Al`s including retracts/cockpit etc,but maybe if I can get this jet for maybe 1k,maybe worth it.
I`ve also read that there is a problem with the thrust pipe not being long enough,was this so with yours (approx 3 inchs too short)? I would be very grearfull if you could let me know of any issues you had with this kit.
Are you going to Classic jets this friday?

Cheers

Hi Steve,

Didnt have any problems with the tube. Did find it a real squeeze to getthe servoes in the wings and stab - used full size ones in the wings, and Hi-text 6245 (I think they are) in the stab.

Needed quite a bit of nose weight, so could have moved the turbine forward a bit.

Yes, 160 is huge, but its all I have other than a 70. Found on the 160 that it flew happily below half throttle.

Came out a bit heavy in my opinion - 26.5 pounds dry.

Also found that space was a bit short despite thre big cockpit area, so plan carefully. Use Multiplex plugs for the wing servo wires - less aggro.

Used a new JetTronics gear valve - absolutely great, as they shut themselves down after 15 seconds s- so less worries about leaks

Will post any other info if I think of it.

And no - no trip on Friday for me - have to keep toiling away so I can buy jet fuel

I guess the P80 will need less nose weight.

Thanks for you input Dave

Just another question if I may.Did you use the 3 fuel tanks as supplied? I presume not due to the larger engine used.Just wondering why you came out som heavey,how much weight did you need to put in the nose?

Thanks

Steve

ps:you got any pics of yours?

The manual calls for 13/16" on the flaps. I've managed to get max throws on them to 1 1/4" on both sides ..... what did you guys end up running??

Hello Ledd4u
Recently I bought a friend a Cermark Viper, and seeking more information about the Viper here on RCU I found this forum.
And seeing the pictures of your Viper I was sure exactly my Viper.
My friend bought the Viper there in Florida. Your Viper has been sold?
If yes, probably he's here with me in Brazil.
As I think I know? The hole on the right side, probably to switch on and off.
And by finishing that you said you did to the seam on the fuselage.
hugs
Juliano
