Ailerons installed. Manual says to use medium CA but I used thin as I feel it makes for a stronger bond and does not clump up at hinge center where I want easy flexing. Horns installed with medium CA per instructions. Servos centered and rubber grommets installed with brass sleeves flat side down. After screwing down I unscrewed them and added thin CA to the wood to give added strength.

The hardware kit comes with 8 small washers. The assembly manual doesn't indicate where they go but I'm using them against the control horn as shown. Once tightened down I'll drop a dab of medium CA onto the nut to keep it in place.

Installation was pretty straight forward with just a few modifications to mounting pocket and strut. :)

These should offer trouble-free landings. :rolleyes: Well worth the added effort!

Nosegear Install - retract comparison
 
1 Attachment(s)
The nosegear retract supplied with the kit mounts from the bottom whereas the E-flite retract mounts from the top. In addition the E-flite is considerable larger. I have spent the better part of the day cutting and trimming the existing mount to fit the E-flite retract. I'll post photos of the the modifications to the pocket and new mounting rails in a day or two.

Nosegear Install - modifying the pocket
 
6 Attachment(s)
Tools required:
X-ACTO knife with No. 11 blade and sawtooth blade
Dremel with No. 420 cut-off wheel and chipper bit
Small modelers wood chisel
Mallet

This was pretty much a learn-as-you-go procedure. Lots of test fitting and 'is this gonna work?' moments. :confused:

Looks great! Just finished mine, White and blue version. Should be flying it any day now.

Thanks Bob. It was a toss up between the blue and white or the red and white as both color schemes look fantastic on this airframe. My final choice was more of 'keep it in the family' as my fleet is predominately red and white.

Good luck with your maiden flight!

Nosegear Install - continued

After much trial and error I feel that I'm nearing completion on this phase of the build :)

Before testing your servo to steering arm connection I strongly suggest that you set up a mix for the nosegear servo. This will cut power to the servo when the landing gear is up. Set up as follows.

I'm using a Spektrum DX7s transmitter.

Mix 1
RUD > AX2
Rate: 100%
100%
Offset: 0%
Trim: Inh
Sw: Gear0

I saw this done on another build thread and... 'an ounce of prevention is worth a pound of cure'.

Elevator install

Installing the stock hinges did not go well. :censored: One of the hinges nearest to the fuselage got hung up and just would not go in completely leaving me with a uneven gap. CA can be very unforgiving. I let it dry overnight and cut and trimmed the hinges flush with the surface and made new slots for Du-Bro small nylon pin hinges No. 118. Test fit them to make sure they would seat properly; had to trim back part of the hinge to get it into the stabilizer section before mixing up some 30 min. epoxy. Tip: before using epoxy on pin hinges bush a little Vaseline on the pin hinge portion and melt it with a heat gun to prevent the epoxy from getting into the hinge area and binding up the hinge.
