My experience with the E-Flite T-34 Mentor has been so good that when I saw this slightly larger T-34 by VQ Models, I wanted to give it a try. This larger model can accommodate retracts so that helped convince me to purchase it. I'm not really crazy about the "printed" covering, so I thought that when I purchased it, if I didn't like it, I could recover the plane in a scheme that I did like.

When I opened the box, I was very surprised to see how well the covering was adhered to the plane. Not a wrinkle in sight. Normally, you have to go over the covering with a iron for good measure even if it looks tight, but in this case, it was already tight and very well attached. The covering is a PVC film with an adhesive base. It will shrink with low heat. When heat is first applied the film will sag as it expands. Then it will reach a certain temperature and then begin to tighten up. At this point, stop applying heat and let it cool. As it cools it will tighten more. Use only very low heat.

Modifications and Notes:

Easiest ARF I've ever put together. The only thing I replaced was the stock ball-links with Dubro links and control rods. I originally set the plane up for sport flying with a motor from another plane.

I decided I really liked the plane, so I went all out with the servo's, Motrolfly motor, and Talon 90 ESC.

Maiden Flight:

August 7, 2013, 5:30 am: Air calm and temp about 82 degrees. Fantastic maiden. 2 clicks aileron, one click down. Fly's like a champ! Did four flights. All perfect. De-lighted.

Introduction:
The Cessna 337 is a very distinct plane because of having one engine in the front of the aircraft, and another in the rear of the aircraft.

Modifications and Notes:

The most serious problem with this kit is the way that the wing mounts to the fuselage. It is pinned in the front and uses T-bolts aft to hold the wing on. Very traditional. The problem is that the rear cowl has an over-hanging intake, that makes it impossible to attach or remove the wing without having to remove the rear prop and cowl. Just plain dumb.

Fortunately, the fix is to move the...Continue Reading

Prop: 10 x 8 Electric Propeller with Ears: C-Z Scimitar by E-flite (EFLP1008E)

Manufacturer's Info Page (full info here).

Maiden Flight:

December 26, 2011. A bit gusty. Although the plane was carefully balanced at the mid-point of the stated CG with the stock setup, the plane flew like it was tail-heavy. It was a bit uncomfortable to fly. My landing was good up until the point at which the nose suddenly bounced back up, resulting in a slightly bent nose-gear on final contact. I did notice as it was taxiing that it seemed to be jumping up a bit, like it needed more weight in the nose, but thought I would go by the manual (lesson learned). Adding about 2 ounces of nose weight was needed. I suppose this plane is really hungry for bigger batteries, which it looks like it can handle.

Overall a very neat plane. Looking forward to getting out and using the thrust vectoring.

I originally wanted to put in HiTec HS-85's servos, but some slight trimming would be needed, so I bought the MC35's thinking that they would be a perfect fit. Turns out I had to trim the MC35's anyway. It would have been better to buy the HS-85's as they cost only slightly more than the MC35's and the HS-85's are ball bearing. Won't do that again.

Not mentioned in the manual, but included in my kit was a pull-pull kit for the nose gear and the appropriate cutouts in the plane. I was not happy with the push-pull nose gear arrangement as it suffers from slop due to the long cable run, this was a great solution.

Painted top and bottom.

The servos are mounted on the top of the aircraft.

Maiden Flight:

The plane was hand launched into the horizon and then power was applied. This was easy to do. Although Xeno seems heavy, this bird loves to glide, powered or not. Flight was fun, and it is amazing how slow you can fly it. Even directed in a 15mph wind with power off, the plane still manages to accelerate somehow. Amazing. Down side, at my field I have to belly land her on the dirt or on asphalt (we are in the desert, no green grass nearby), she is a little...Continue Reading

Modifications and Notes:

Initially I was going to use a HS-65 MG servo for the retracts, but DSR-30T Electric Retracts were used instead of mechanical retracts. These were very easy to install. I followed the existing mounting rails, and glued in supports for the new retract mounts. A BEC set to 7.4 volts is used for power. Especially important is that the electronics of the DSR-30T offer logic to prevent gear-up when transmitter is turned-on with wrong switch position. To save...Continue Reading

Description: The analog current tester for servos and radio receivers.

I've been doing electronics for many years and recently had a problem with some servos. I needed a way to tell how "healthy" they were. The analog current meter is a very simple, inexpensive, and powerful tool that will allow you to measure the current draw of any servo (or match multiple servos). Any pilot with an airplane, helicopter, or other flying object that uses servos should have this great diagnostic tool in their toolbox.

The problem: If you try to measure the current draw of servo with a digital meter you will find that most digital meters will display an ever-changing cascade of readings while operating the servo. These readings are mostly useless because of the way that the digital meter “samples” the reading. A way to “smooth out” the readings, and to get a sense of what is going on with the servo is to connect it to an analog panel meter. Although some digital meters have a “bar-graph” to show changes in the readings, I find that the analog meter is easier to interpret, and is cheap enough to have in the toolbox.

Quick and Easy: The amount of current drawn by a servo increases dramatically when the servo is binding. A simple analog meter is an inexpensive way of telling if your servos are healthy and drawing the right amount of current, or drawing excessive current due to some other problem like binding.

Not all servo or control linkage binding is obvious....Continue Reading

My AUW: 11.3 oz (321g)

Modifications and Notes:

This is my first soaring plane. It is very nicely designed, went together perfectly, and has a great manual.

I added a Volt Watch monitor for the 4 cell 4.8 volt 700mAh AAA-size NiMH battery. This was a freebee from Tower so I was happy to finally find a use for it.

I installed a Lost Model Locator available from Skyking RC Products. I used a sharpened 1/2" brass rod to nicely cut a hole into the fuselage to fit the alarm. I really like this alarm, as it has a very hard-to-miss up-down tone that can be activated by turning off the transmitter or by flipping the "gear" switch.

I also cut the excess wiring from the servos, wiring harness switch, Lost Model Locator, and Voltwatch. This saved alot of excess wiring (see last image) having to be stuffed into the electronics compartment. A crimper and servo connectors were used to make the custom length connections.

I discarded the clevis's supplied, not because they weren't nice, but because I prefer E/Z links (Du-bro 845) and a good Z-bend. Epoxy and heat shrink was used to fasten 0.047" music wire to the provided fiberglass rods. This arrangement is lighter than the clevises.

The plane was covered with Coverite Microlite. It adheres well, but will also come off again, in case repairs are required.

Scotch High Performance Packaging Tape, Blenderm, and fiber reinforced tape were applied as well. I used Scotch Gloss Finish Multitask Tape for the hinges (I think it sticks better than Blenderm in this app).

I needed a penny in the battery compartment and some extra fiber reinforced tape on the nose to balance the plane.

Modifications and Notes:

This is my first laser "kit" build. It was fun. I learned alot from brucea's covering tutorial that I applied to this plane. I wanted this plane as a trainer for my girlfriend so that she could have a full size plane at the field to train on.

The instruction manual was good, and the build was easy, but I would caution a first time builder that you need to practice beveling a control surface and use care sanding, especially the ailerons. My only complaint is the need for more clearance for the aileron cutouts, they are a bit too "tight" for my comfort; I shortened the ailerons 1/16" for more clearance, and I'm glad I did, because that clearance was needed after the wing was covered.

I modified the...Continue Reading

Modifications and Notes:


I went with all digital servos, for this plane I think they are worth it.

I added the (I think very important) MaxxProducts 6970 Arming Switch for safety. Just a personal note: I think that Maxxproducts should call it an arming "plug" instead of switch, as I think more people recognize that term and would identify what it does more clearly.

EC5 bullet connectors were used for power connections instead of Dean's Ultra's. I really like these EC5 connectors, (they are pictured below, and you can see them at this link over at HobbyKing). I have converted all my batteries 3200mAh and over...Continue Reading

Center of Gravity; CG: about 1" back from the center of the wing.

Control Throws: Reflux the elevons and trim them both up about 1/8" (3.2mm). This is to compensate for the "flying wing" tendency of the plane. Ailerons and elevator go about +/- 0.75 inches (19mm). The elevator is sensitive, and because of its size needs solid linkage.

BUILD:

Wing halves – I used hot glue and masking tape to align and adhere.

Hinges: I used my “Dual Offset Tape Hinge Method”. Click on this link on RCGroups to see this method. This method is great for cold weather applications as it produces very flexible, tough hinges.

Fuselage - I split the solid block for the fuselage into 3 pieces so I could glue the structure together. I didn't want to "poke" holes into the fuselage with a hot tip. I created a "flow" chamber for air to flow past the...Continue Reading
