1 tbm dv8r manual revised 1/4/2010 note: this manual will be updated continually as new information is obtained. The dv8r (pronounced deviator) was pcm model’s follow up to the av8r (aviator) sport trainer jet but was a completely new model designed from the ground up to be a superior all around per...
2 it is an arf. The dv8r is the premier jet for grass runways. It combines high performance with low wing loading for easy take offs from any surface, and easy landings. Being wood and covering rather than fiberglass, if you do have a mishap, repairs are quick and easy. Experience level building the...
3 engine selection - please read! The original dv8r is still flying with a jetcat p80, which is a perfect match for this model. Tbm built its prototype arf with a jet central 36 lb rhino only to test out the dv8r’s maximum capabilities. The rhino is not recommended as it is too large. We recommend t...
4 1) retractable landing gear with valve, air tank, air lines, servo, etc. The bottom of the wing is ready to accept the landing offered by tbm. This gear is of trailing link design for shock absorbing. This design is great for grass runways, or for cushioning a hard landing. 2) brakes, brake valve,...

6 6) install batteries and radio 7) fuel up with kerosene and go fly build instructions note – most planes of any type are tail heavy. Temporarily mount the batteries in the nose. They can be easily moved rearward if necessary. Note 2 – some builders recommend building the plane as much as possible ...
7 2) push the two halves together and clamp in place. 3) do not install the fuel tank as shown in the photo below. This is the smoke tank mounted in front of the fuel tank(s). The fuel tanks are behind this tank on the cg. Fuel tank installation below is a photo of the installation of 2 dubro 50 oz ...
8 4) install overflow fitting. It goes off to the right in the photo below, through the fuselage. The overflow/startup tank then can rest on the wing. 5) plumb tanks as shown. There is plenty of room to add a smoke tank in front of these tanks if desired. 6) attach the tbm bft (bubble-less fuel tank...
9 tbm bft has velcro hot glued to the tank. A band of one-wrap velcro hold it in place. After the assembly is completed, glue in place as a unit. See next photo for placement..
10 photos show placement of batteries, steering servo, retract, ecu, air gauge, receiver, brake and retract servos and valves, on/off switch, bft, fuel valve, etc. Note that the air tank is located under the false floor on the opposite side of the bft..
11 photo of another pilot’s layout of equipment inside the fuselage. Nosewheel and steering installation install nosewheel steering servo as shown. Install the nosewheel retract. Install the nosewheel steering. The nose gear steering is activated via pull-pull set up. Locate the materials to make up...
12 hinging all control surfaces – the prototype used ca hinges. While the proved adequate, we upgraded to flat pin hinges for production. Pin hinges have less resistance than ca hinges, and last longer. The chinese do not do a good job of cutting slots for flat hinges, so the slots are not cut in pl...
13 term storage. If you prefer to glue to the two center sections together to provide increased structural integrity, you are welcome to do so. Note: be sure to glue the joiners into the wing tips. You don’t want anything sticking out of the center section of the wing with the tips removed. This mak...

15 from the photos, you can see how the wing tips are held onto the center section. There are 2 spars, one made of cf in the front and one made of aluminum in the rear. 1) test that the rod (machine gun) goes completely through the 2 spars. 2) find the hole in the front of the wing, and open it with...
16 3) install included hardware. Use 2” titanium linkages for ailerons, 1.5” for flaps, ball links, and swivel clevis and horns..
17 elevator, rudder and aileron servo installation 1) all the servos for the control surfaces are similar. Install the servos using the mounting blocks (provided) as shown. Glue the mounting blocks to the hatches after you trim them to the correct size. We provide 4 wood blocks 1” x ¾” x ¼” for this...
18 2) use 48” servo extensions with safety clips. (or use 36” extensions and a y-harness though one servo must be reversed electronically as discussed above in radio section).
19.
20 3) install the control horns by opening the holes in the covering, drilling to the appropriate size, soaking with thin ca, and assembling. 4) install spars into the elevators as shown using hysol 5) remove covering and glue wood to wood to permanently glue elevators in place. Note: always put a d...
21 rudder servo hatches moved to the fin instead of the fuselage..
22 5) remove covering and glue wood to wood to glue rudders in place..
23 original style rudder servo mounts. Don’t use these. This photo shows the covering removed for gluing the rudders to the fuselage. So the same for the elevators. 6) if you use the inner hole on the swb arms, then set the horns about 13/16” away from the surface from the rudder..
24 all control horns should be at about 1” as shown with about ½” servo arms. We recommend 1” servo arms, yet use the inner hole. The throw required is minimal, yet we want full servo travel to maximize the mechanical advantage of the linkage. Turbine installation installation of the turbine is simp...
25 components have been installed for cg reasons. You can easily move the turbine fore or aft several inches to change the cg. For temporary installation use 2 small wood screws. Once you are satisfied with the cg, permanently install the turbine using machine screws and blind nuts. Permanently inst...
26 photo of engine rails. These will need to be cut down for larger turbines. Use a drum sander and a vacuum cleaner to remove material. Canopy the canopy can be painted as shown or not painted. You can have one pilot or two if you prefer. There are many options. Simply paint the outside of the cano...
27 retract and brakes the wing is already cut out for the tbm retracts. Test fit the retracts in place. Modify the mounts if necessary. Screw the retracts to the blocks provided..
28 photo shows bulkhead fittings and holes for bulkhead fittings and for aileron and flap servo extensions. These holes are hand cut in the prototype. In production the holes are laser cut..
29 a. Photo of bulkhead fittings and aileron and flap servo extensions in place. B. For the brakes and retracts we suggest that you purchase 3 different colored air lines to keep things organized. We suggest 1/8” or 3mm line. Either of these lines work well with festo 3mm fittings. C. Purchase 6 of ...

32 photo of the new flaired area. The bottom front of the wing is now built up to mate perfectly with the fuselage. The wing can be 1 piece, 2 pieces, 3 pieces, or 4 pieces. Pilot’s choice..
33 photo of the left vertical fin and rudder. Note servo mount is now in the rudder for a cleaner look. Install the heat tape the heat tape was not installed on the back of the plane to facilitate wiring of the elevators, rudders, and turbine. When you are happy with the set up, install the heat tap...
34 flaps and landing one last note deals with flap operation. Most radios have the ability to put flaps on a knob or dial. Also many radios have an available three (3) position switch that is either a dedicated flap switch or one that is available as an auxiliary channel. I have found that the three...
