Unboxed. Went together like Lego.

These are the two colour schemes i will settle on for stock models unless anyone has any suggestions. Lots of other colour schemes available to order..

The Pre-installed LDS is not a system i am familiar with until now. Only used to Servorahman IDS. Seems very good i like it. Saves a load of hassle that's for sure...

Kingmax CLS0612W going in sweet as a nut on the ailerons. Lots of movement and no buzzing at neutral. 

Like for servorahmen IDS, the Samba LDS horns are a tight fit so had to remove the tightening screw and gently open up the clamp and wiggle the servos in. When done the screw can be re-fitted and clamped up for an extremely secure set up. The output horns on the Kingmax are identical to KST. When i used to sell KST the IDS horns were an equally tight fit on the KST output gears. Better this way than sloppy horns.

Short 50mm leads make for a neat clean finish

Flap servos in. I am really impressed with the Samba LDS system. It is very smooth, rigid and slop free. Very impressed. And the geometry is perfect. Flap servos need only a few percent here and there for symmetrical crow flap movement.

Only criticism is the inital fitment of the spline into the hub. It is a bit tight and you need to wiggle the servo in and use a bit of force. But once you get the servo horn in once the next time (s) become very easy. I think this is due to newly machined servo output splines going into newly machined LDS hubs. Both will have crisp sharp machined 90 degree edges. Once these get edges get slightly rounded and chamfered from the initial fitment the horns then slot in beautifully.

Next batch of Precision 2's in September  will be the last ones with free wing & fuselage bags and free fitted LDS system. We will still offer the best airframe price possible but the covers and bags will be at an additional cost as per normal. Thanks

Nice to have all the wiring including the MPX plugs all done and dusted.  

Fixed into wing at factory, just need fixing into fuselage wing root.

KingMax servos fitted into wings. As Neil said it takes a little persuading to get the servo heads into the lds heads . New splines and no taper/lead-in makes it a trickier operation that it should be. Still a massive improvement on fitting the whole assembly yourself . Impressed by the ‚Äúgearing‚ÄĚ of the drives, it seems Samba have spent time making this just right . ¬†

Imo too many models use of the shelf systems that are not optimised .

It is very colourful. Wiring all done and fixed into wings by Samba. Only needed to feed the wires into the fuselage and epoxy the Mpx  plugs into their corresponding fuselage recesses. No fiddling trying to line them up. They worked perfectly. Receiver plugs all nicely labelled. 
fuselage pushrods are made at tailplane and tailplane horns are in. Just have to cut servos into fuselage and make servo end of pushrods. 
waiting on delivery of fuselage servos as I wanted to use the same type as in my other models. 
18650 battery pack is a fit.

install took approx a day, if servos slotted I’m easier it could be done in an evening.

Received my Pike Precision 2 today.

Dry fit for a couple of pics.

Hopefully I get the time to get the radio gear over this next week and maiden it in Wales before the comp on Saturday. 

Thanks Neil/Flightech UK

Not the brightest of days for a maiden.

Pike added some sunshine!

Settings all transferred from my Green one using a digital angle meter.

Perfect result in the conditions yesterday (light) it immediately felt "spot on".

As standard the servo covers pre-cut out of a clear perspex acrylic type material. They are a perfect fit just needing a bit of canopy glue or thin doubled sided tape internally or clear diamond tape type stuff externally to fix in place. Whilst i would normally leave these clear to show off the kingmax servos i thought this time to spray them on the insides like an rc car bodyshell to make the samba lettering complete...

All servos installed 

KST X12 in the fuzz  with X10  and X10 mini  in the wings,all HV .

Still unsure on battery,18650 or Life4. 

Need to add nose weight to get CG then the maiden hopefully next weekend at the English Open weather permitting.

Nice job Les.

I am thinking 5 cell nimh 2/3 AF in llll- format. All these Lithium based cell formats just dont fit very well

18650 will fit in the place of 2/3a cells generally. And those 1600 life packs are about the same size.

In my view Neil, few cells are more reliable. 2 cell with balance lead is the current best technology for a safe installation. Using 2/3A and 5 cells increases chances of cell imbalance, no balance lead increases the chances again. Cells out of balance  can fool the charger, and fail quickly when put under load. 
18650 cells fit fine, if you have a receiver of the right size. Nose cone is a perfect fit over my JETI  receiver. In the picture it is hot glued to the fuselage and a magnetic switch glued to the receiver. 
wires run neatly under receiver where there is plenty of room . 
I use 2 mm banana plugs to connect power at the start of a days flying. The battery ends are hot glued to battery pack to reduce movement and stress to wires.

Hi Neil 

I've been using these for a good few years now and work great 2cell Life4 1600mha ,also 18650 2 cell.

Both will fit perfectly. 

Tom's building me a new pack of 18650 to go into the PP2.

I was looking at those only this morning Les. I might use those then. I have used the Hyperion 1450 Life in f3j models okay towards the end of the class in 2016.  When i did f3b and slope it was all nimh. Or even nicad.

All i do now is connect a big 4s lipo to an esc and it all works.

With the good advice now received about the batteries that are being fitted into f3f models and the fact i have to use multiplex receivers, it appears tbe multiplex receivers are a bit bigger than other brands making my installation that bit tighter for space

Thanks
