Congradulations on your purchase of Donatas Design, aeromusical plane Arrow V.5. This plane is
evolution of famous 4D trainer with variable pitch propeller placed inside fuselage. Arrow V5 is
latest version of this plane, that is extremely good choice if you want to learn 3D ore 4D flying.
Plane kit come in two versions regular and milled. Regular version is preffered option for
beginers, and pilots that plan to fly Arrow outside in light winds. Not milled version is also
stronger. Milled kit is made for competition pilots and flyng with Variable Pitch propeller. Milling
save about 9 grams, and as we know weight and wingloading is very important factor in F3P
competition planes.
Arrow V.5 is intendet to be powered by 18,5g AXI2203/RACE motor and 2s light lypo battery if you
fly indoor. If you plan to fly outdoor AXI 2204/54 with 3s light lypo is recommended. Please have in
mind if you sellect more powerfull motor aditional reinforcements to airframe will be necessary.
This kit include all items that are necessary to finish kit, depron parts, carbon rods, flat
carbon, hi quality fiberglass hardware set, motormount, Z ends for servo attachment, velcro
tapefor battery fixation and pull pull line.
Equipment selection
Motor:

AXI 2205/54 (For outdoor flying in light wind, motor weight 25,9g.)
AXI 2205/54 EVP (VPP flying, motor weight 25,9g ).
ESC:
Competition option Castle Creation Phoenix 10a , budget version CC Thunderbird 9.
Battery: Desire Power V8, 35C 300mah, 2S/7,4V , battery weight 16g. (Light indoor)
Desire Power V8, 35C 380mah, 2S/7,4V , battery weight 22g. (Powerfull indoor)
Desire Power V8, 35C 380mah, 3S/11.1V , battery weight 30g. (Powerfull outdoor or VPP)
Servos: Dig. JR 290G single servo for elevator and rudder, 2 servos can be ussed on ailerons.
Dig. JR 188 single servo for elevator or rudder, 2 servos can be ussed on ailerons.
Hitec 65hb single servo on ailerons and rudder
Radio: At least 4 ch programmable radio with minimum programming of exponential. My advice
would be more advanced radio like JR 9 or JR11 that have travel adjustment, dual rates, trim steps,
digital trimmers, mixes and other useful functions, that will help you setup plane fast for best
performance.
Receiver : As light as possible, i use with great sucess: Spectrum 2,4ghz Ar6300 2g.

Summary of Contents for DD ArrowV5
- Page 1 Assembly manual Congradulations on your purchase of Donatas Design, aeromusical plane Arrow V.5. This plane is evolution of famous 4D trainer with variable pitch propeller placed inside fuselage. Arrow V5 is latest version of this plane, that is extremely good choice if you want to learn 3D ore 4D flying. Plane kit come in two versions regular and milled.
- Page 2 Here you can see fiberglass hardware set. It is done to achieve best control of your moving surfaces. Now you can use long servo arms and servo horns, this will allow you to have less pressure on control rod and also use full potential of your servos and not lose resolution. Also few small piece will reinforce areas that face allot of forces.

Page 3: Required Tools And Adhesives
Required tools and adhesives: You will need just few basic tools and materials to finish your Arrow V.5: Sharp hobby knife, file ,1.5mm dril, piece of sanding paper, scizors, screwdriver, solder, Donatas Design beveling tool. Mercury Adhesives foam friendly CA glues (M100F), Mercury Adhesives Accelerator MH 16 M3 medical tape for control surface attachment. - Page 4 Optional reinforcement: Glue thin carbon (that is left from „shaving“ main carbon spar ) like shown in picture, this give very good strenght for elevator and prevent stabilizer part from cracking. Glue 0.5mm carbon on back and leading edges of the wing. Carbon lenght required for back edge is 70cm, for front we will need 83cm carbon lenght should be.
- Page 5 There are few ways how you can attach elevator and rudder. Easier one is to use Donatas Design beveling tool and cut control surface by angle, and then ussing blenderm tape attach it to fuselage (same way ailerons are done).Such method is good when you use solid pull push system. But if you use pull pull cables, tension on hinge line will displace rudder or elevator.
- Page 6 Now its time for one of most important steps durring building of your Arrow V5. Place tail section to main wing as shown. Use some heavy objects to lock parts on flat table. Measure very carefully distance from each wingtip to stabilizer, it must be exactly the same. Also be sure tap line where bottom of fuselage will be connected is in one line.
- Page 7 Glue flat thin carbon piece as shown in Cut holles for V shape carbon reinforcement. picture. This will reinforce top of fuselage and This is necessary step to ensure both sides of in case of inverted landing will help to protect elevator deflect ecactly the same.
- Page 8 Now we need to prepare main wing support. Here you can see reinforcement piece made from 0.5mm fiberglass. In your Arrow kit you will find similar detail, glue it in center of wing on bottom of fuselage. Mark 23 cm distance (measuring from fuselage towards wingtip). This will be point where wing support from 1.5mm will be connected.
- Page 9 Now when kevlar thread is in place and carbon rods are already glued in place put plane again on flat table. Use some weights to press it down to table. Now double check vertical fuselage position and apply some CA glue in center of fuselage. Now you can glue two support SFG’s from depron to wing support carbon rod.
- Page 10 Carbon structure from different angle. Now it is good time to glue in flat carbon pieces to V shape openning we cut earlier. When you glue flat carbon inside depron, glue fiberglass square plate on top and bottom of elevator as shown in picture.
- Page 11 While we did not attach top of fuselage, now it is good time to prepare and install landing gear. First of all i like to reinforce stresfull areas near landing gear. For this task i use some 6 cm piece of thin carbon and fiberglass cloth.
- Page 12 If you decide to use single servo, glue servo in, and after that glue top of fuselage as shown. Cut holle for aileron horn as shown. Try to do it exactly same on both ailerons. Next picture show aileron servo arm , Take original servo arm and put it on servo trim and sub trim on your radio must be 0.
- Page 13 If you decide to use double servo, glue holle in wing front. And prepare location for servos, cut servo size hole in both SFG’s as shown. Having two aileron servos will require little more work to setup but in my opinion it worth time spending time, because you will receive few obvious advantages. First it will be much easier to place battery where ever you want.
- Page 14 Here you can see 40mm x 1.5mm carbon rod installed to elevator. It must be exactly same lenght on both sides. Cable that is providet with kit will work fine, but same as with ball links i preffere to use slightly different material for my competition models.
- Page 15 Very end of connection is done with stronger fiberglass tape. Also i put soft velcro on point where tail will be touching ground, this will remove noise durring take off and landing. Next step will be motor mounting. If you decide to go with regular motormount, this process will be very easy, you can use wooden ore fiberglass motormount.
- Page 16 Optional: For more advanced pilots i would recommend to try to called TV (Trust vector control) system. This mean motor will be moving to sides mixed ore connected ro rudder. Such upgrade will allow you to make some crazy maneuvers. Here you can see construction of such system. I use ball links connected to motor for smoth and noise free system.
- Page 17 Here you can see exact dimensions for each side connection. Notice there are two ways to control TV, with same servo as you use for rudder ore with separate servo. Ussing one servo will save you weight, but TV willrequire powerfull servo such as JR 290G ore Hitec 65hb. If you gonna use one servo pull pull cables must be crossed in one side of the plane, otherwise motor will move to oposite dirrection than rudder, and there will be no benefit.
- Page 18 Here you can see dual rate and exponential setup for all surfaces. I use full deflection of all surfaces all the time, and therefore i preffere more expo’s. For competition flying 2 minutes aeromusical routine goes by very fast and durring two minutes switching flight modes for different control surface deflection would be not wise.
