this is the Build log of Park Master 3D (http://www.rcdhamaka.com/index.php?main_page=product_info&cPath=3_46&products_id=665)Everything came neatly packed, all parts in its slot, well laid out.

(a) Pretty simple, beautifully laid out directions, A few Critical areas are

    (i) Follow the instructions Meticulously, like not putting the second aileron before sliding in
    the wing, not fixing the second wheel etc

    (ii) Slots for the hinge can be tricky, used Vernier to measure the centre before making the
    slot

    (iii) Used 2218 Motor, should be good for 3D (http://www.rcdhamaka.com/index.php?main_page=product_info&cPath=100_93&products_id=517)

    (iv) Drop Bond CA 190 is safe on this Elapor, however i used Evotite

    (v) Do not glue Undercarriage fairing to the fuse, shock transfer to the fuse will be without shock absorbed

whichever surface you keep the wing after applying glue make sure the wing doesn't stick to that surface

Aileron to wing root clearance is just 1-1.5 mm, make sure you have it otherwise aileron will foul with the wing

There is a 2 1/2 mm dihedral on each wing, that will be 5 mm on one wing tip if the other wing is parallel to the ground

Put a wing skid there, RCD has some. Control horn can also be used as skid.

I wanted pdf plans for this. Is it available?



BTW it is a wonderful plane. Palash from IHC was flying at our college. When i asked him the price he quoted it at Rs 10,000. Luckily we have more dedicated Lhs's like RCD.

Hi Augustinev,
                  How meticulously you publish you build logs,  I really appreciated your spirit of sharing.
I see clearly good composite plastic foam and excellent design.

Thanks for sharing

Thanks Karthik

(a) reinforced Motor mount with hot glue, 2218 has the capability to tear the mount apart

(b) Went with SLS on the skid, saw Santhosh's post later

(c) Moved the batt as far back as I can , CG is at 92 mm instead of 110 mm. Any ideas?

(d) Batt woudn't fit in height had to sand the slot a bit

(e) Used 50 Amps ESC from HK, could've used 30 Amps decided to go with 50 Amps for starters, 2218 with Mystery 30 Amps ESC ran slightly warm last time around.

(f) Had only one, the best in its class Power HD Servo, therefore, decided to go with 9 gms HK servos. Hot glued it with a option of removing it later, as and when RCD/ anyone else stocks it, will replace it with power HD.

(g) Used recommended 10x4.7 Composite SF Prop (http://www.rcdhamaka.com/index.php?main_page=product_info&products_id=39)

Pricing

RCFORALL sells it for 9800+350 :Rs: for shipping (http://cgi.ebay.in/MULTIPLEX-PARKMASTER-/150564215584?pt=LH_DefaultDomain_203&hash=item230e539b20), website says 2x 18 gms servos,it is a typo,  you will required 4x9 gms servos

RCD Charges 6948 :Rs: (with 5% Vat) and i think, about 300-400 :Rs: for shipping

I think my motor is overpowered for the model. in less than half throttle she is doing wonderful hover.

Model has four thrust adjuster nuts with that you can adjust downthrust and sidethrust

waiting for the videos :headscratch:.hxt900 servos are not good for this, use some high speed servos

rcpilotacro

was impatient that's why mounted this servo with hotglue, will remove it later

Flew 6 sorties in the morning, sorry no pics permitted there, where i flew, few issues cropped up,

1. 2218 is way too powerful for the model. therefore changed the motor, pics soon
2. Prop and prop nut came off in hover (with 2218), thankfully i was hovering high, a quick stall turn gathered just enough speed for a kisser touchdown. i wonder how? did i not tighten it properly ???
3. Batt fell off in a knife edge (Wasn't fixed with a velcro, thought it fit like a glove in its slot, i was wrong) wire got wedged between fuse and the aileron, landing was with rudder and elev (Like our GWS Slowfly) , no issues there, thanks to XT 60, it held.

Rest of the three sorties were gr8

PS
maiden was as suggested in the book, 30% Aileron 50% Elev, -50 Expo on Aile and Elev, In this config she is like a very docile trainer, nothing fancy about it, now throw s/w 'B' (Thats what i assigned) she is a monster, roll plane is extremely snappy.

PPS
Pics and video soon
