The aileron inner end has a width/chord of 50 mm so I decided to have a constant 50 mm flap chord from the aileron to the fuselage. I used a long straight edge/ruler and placed painters tape “loops” on the bottom to keep the ruler from slipping. Using a new large box cutter I made perpendicular cuts along the ruler’s edge. The 1/16 inch balsa was easy to cut through but the root end had hardwood and I used Zone saw for that. After separation I used a sanding block to lightly sand away any imperfections in my cut. I then used my straight edge to cut away the top of the flap for reflex. Again I used the sanding block to lightly sand away any imperfections.

I used 1/64 inch thick plywood to face the flaps and wing. I cut 4 lengths of ply a little wider than the faces and made sure the bottom hinge edges were straight and true. I used blue painters tape to hinge the facing on to the bottom of the flap. I then used 5 minute epoxy mixed on to scrap paper before smearing it on to the plywood. After closing up the hinged plywood facing I laid it on its edge on my cutting board and cut away the overlapping ply with my box cutter. I then used painters tape to keep the facing up against the white foam and balsa wing sheeting. Total time to cut and face the flaps and wing was about 2 hours.

After leaving the epoxy to harden overnight the next morning I removed all of he blue painters tape that was keeping the ply facing against the balsa wing sheeting. About 5 %...Continue Reading

This technique can be used on any fiberglass or CF canopy (like the Allusive CF canopy.

The Allusive does not have any intake vents other than the firewall and has no exhaust vents. Other owners have used the aluminum turbo spinner to cool off the motor shaft and motor. Others have used spoons or scoops that stick out away from the fuselage. This technique uses intake and exhaust cutouts.

I used blue painters tape and cut out 2 intake and 2 exhaust templates. There is more exhaust area to allow for low pressure movement of hot air inside the canopy area where my ESC and battery are located. Air entering the turbo spinner hole and firewall holes can exit thru the exhaust vents.

I positioned the blue tape templates so that the folding prop would not interfere with the vent openings or the CF hold down strip under the canopy. The canopy sill was used as a guide to place the blue tape templates. Using a diamond rotary wheel on my Dremmel I cut along the edge of the blue painters tape as shown.

Using 1/16” plywood I cut out 8 vent sides for the 4 vents. After wedging the vents open with scrap plywood I used CA kicker and medium CA to glue the ply pieces to each vent. After they were dry and secure I cut away excess wood and then used regular Gorrilla glue to reinforce the ply pieces to the CF canopy....Continue Reading

I recently bought a used Allusive motorglider with Hitech MG servos and a NTM Motor with an Eflite 40 amp Lite Pro ESC. Specs state 55 amps for 15 sec. A hard brake was programmed using the ESC online manual.

The 12/7 prop on 3 S used 30A and 325 watts.
With the same prop but with A 4S she drew 45 amps and 623 watts.

This is a brief explanation on how to configure your talking DX 5, 6, 7, 8, or 9 transmitters. The photos are the same or very similar. You must have an AR636 receiver that comes with the 50 or so models that are the Bind and Fly type. You can buy a receiver from Horizon and have them program an “open stock” AR636 receiver for about $90 (as of Nov 2019). Most of the older types of wood or foam models can use the AR 636 receiver. The receiver must be solidly mounted and orientation is important and reversing the direction of the elevator, aileron, and rudder channels can’t be done at the transmitter. A $7 servo reverser, or a reverse servo are some ways to solve this situation. Removing the servo output arms and repositioning them 180 degrees so they push or pull the flight control surface is another way. The pushrod or tubing must not bind or interfere with anything and this may take time and effort. Purchasing a program cable and connecting it to the Bind port of the receiver is another way. You must use a Windows computer or tablet, and download programs and updates. Learning how to program the receiver can take some time. Terms like relative and absolute gains and flight modes must be understood. There are Spektrum videos and third party programs to help. If you enjoy spending hours on your Windows 7 or newer computer then read RC Groups on how to program your AR636 receiver. The pics are numbered and correspond to the following paragraphs.

Flys great using the V900 AR636 programmed by Horizon Technical.
Eflite Power 52
Castle Lite 100 amp
APC 13/8
5S Glacier 5300

7-9 min with moderate power use.

Did not use cable to reprogram RX but used 3 electronic reversers

Y channel for ailerons on ch 2
Flaps are on ch 5 and 6

SAFE On/Off on DX8 switch B0/B2

The Maule has 3 plugs (aileron, flap, and wing led lights that must be connected and stuffed into the left and right wing panels. They come with a label but after time the labels disappear and it’s easy to make a mistake. I’ve engraved the black plastic and used white paint to identify them but it’s still a potential problem. About a month ago I took off and there was not the usual aileron response so I landed and found out that I had connected the flap to aileron plugs witch rendered no aileron movement. However because I usually mix ailerons to rudder I was able to steer with rudder only using the right stick.

In my rush to complete a test flight I failed to complete a flight control check. It was on my pre flight DX TX Checklist but I failed to complete the drill. Lesson was learned. Yesterday I found one of the pins bent and it would not seat correctly so I had to resend the pin for correct spacing. I decided to fix this problem and improve the connection process for ease and reliability.

My Radian Pro has been flying since it first came out. I converted the plugs to a glued in single plug and I’ve had no problems with over 100 or so connections and disconnections. The pins are bigger and stronger than the typical servo plugs, Deans, or other pins. The spacing is bigger and there is more surface area for glue to bond with foam or wood support.

I ordered the same type of connectors for my Maule except it’s a 6 pin plug with a matching header. I will use 2 pins for +/- power, 2 pins for the aileron and flap signals, and 2 pins for the +- led power.
