I’m a big fan of the large Haigh-Style tailwheel assembly manufactured by Ohio Superstar Products. I find them easy to install, they provide good dampening and are extremely durable.My only issue...and I may be the only R/C’er in the world faced with this problem, is the amount of built in swivel.
The way that the wheel assembly is manufactured allows it to pivot 90 degrees left or right of centerline. While this design provides 180 degrees of travel, I seldom, IF EVER, need that amount! In fact, about 30 degrees total travel provides total control on the ground, both on paved and grassy surfaces.
Another issue with the design is that the tailwheel will sometimes hang up at 90 degrees whenever full left or right rudder is employed. Although the wheel will pivot back to center upon landing, the added (unsymmetrical) load on the rudder servo during flight makes for some interesting maneuvers!
Okay, so here is my fix. I’ve installed a pair of “stops” that restrict the total left and right travel to approximately 35 degrees in either direction.
Rummage through your spare supply of music wire to find a size that looks appropriate for the job and that you have a drill bit to match.
Using the wheel collar that came with the tailwheel assembly as a guide, either scribe or mark with a pencil the outer diameter of the collar on the top (flat side) of the bracket. This is somewhat important because the collar must be able to fit between the pair of pins that you’re about to install.
Drill one hole outside the circumference of the collar and as far forward to the edge of the straight side as possible. The hole should be drilled all the waythrough the first side and only HALF or less of the way into the second side of the slot. This allows the pins to be held in place by simply swaging the top of the holes.
Measure the total depth of the holes and reduce the measurement by a small amount. The pins need to be slightly recessed in their respective holes to allow for swaging.
Drop the pins into place and swage (dimple) the top edge of the holes.
Reassemble the tailwheel and note that the pins now use the collar set screw as a “stop.”
If you find that you’ve either misjudged the distance between the pins or if they tend to hang up slightly on the collar, just grind the outer dimension of the collar to make things work smoothly.
Perhaps someday Ohio Superstar will consider altering their design by milling a curved slot vs. a straight slot for the collar. In the meantime, this solution has worked great for me and I hope it does the same for you.

I acquired this Giles 202 and have purchased a DLE 111 for it. The plane has on the wings Ultimate Charger II and built by Dr. R Suding. I did some digging and found some information but would like to find some more. I found an article from 1999 in
Farm flyers rc about Dr. Suding and know he invented and developed the Ultimate Charger. I will post pics as I go but here is what I am starting with.
F3A EUROPA PRO composite body airplane.
Produced in Europe using top quality German made epoxy resin and glass/carbon fiber.
This professional EUROPA PRO is the result of 23 years experience in F3A world and his research in best F3A performances. This innovative design combined with the extremely lightweight structure, the full composite fuselage, wings and stabs, give the EUROPA PRO an impressive precision and smoothness at any airspeed and flight condition.
The plane is a total novelty: the new fuselage is wider and wing area lower;
The EUROPA PRO is the most economical version of this high performance F3A plane. As you can see the whole hard ware and high quality electronics including batteries are available, the plane after assembly had 5 flights in total, 3 of them was for trimming the angle of attack of the wings and other two just for pleasure.
The reason I am sealing this beauty is because I start flying Large Viper XL turbo jet and to be honest I lost interests for propeller propulsion, so for time being my EUROPA PRO collecting dust in my work shop. Once this plane was built/molded and design the color scheme I install the most expensive equipment on it as you can see.
Here is the ruffle real price of the hard ware:
Motor: AXY gold line 6kg to 8kg +/- 500$
ESC: Castle 100A (new version) +/- 120$
Servos: Hyperion (10kg-16kg) +/- 200$
Power Box: Gemini II +/- 150$
Board Batteries: Power box 1500A two of each +/- 220$
Main Batteries : Turnigy 5000A two of each by 4C +/- 140$
The Body: +/- 2000$
APC prop with carbon cowl: +/-80$
Custom made protective transportation covers: +/- 100$
And the small hard ware parts like hinges, titanium linkages and etc I am not tacking in to account.
Wing Span - 1870 mm Length - 1980 mm Wing area - 60 dm Flyweight - 4850-4950 g
All together 2000$ + shipment
If someone is interested, please contact me on firstname.lastname@example.org
Regarding the shipment I need to find out depended where it goes.

Here is a video everyone. This is the Edge V3. My plane is almost a year old now and still flying great. This has the torque vectoring motor mount which is controlled by the rudder servo. Cool plane. Very acrobatic and fun to fly. Enjoy

The Xracer Quadrant BLHeli ESC from FPV Model does something that you may have never seen before. It lets you decide whether to install it on the quadcopter's arms, as usual, or you can combine the ESCs into a 4-in-1 board that fits in a 36mm stack. The ESC takes up to 6S, runs BLHeli_S, supports up to DSHOT600, and costs only $12.99, so... WHAT MORE COULD YOU ASK FOR???
1. Can be installed separately on the arms, or 4 ESCs installed together like a PCB under the flight controller.
2. Powered by high performance EFM8BB21 MCU.
3. Flashed with BLHeli_S program. It supports multishot/one shot42/oneshot125.
4. Dshot150/Dshot300/Dshot600 Compatible.
5. With 25AMp constant RMS, 30A max.
6. Designed to support 4-6s Lipo, but work well with 3S also.
7. Only 2.5 grams each piece and 10 grams for a set of 4 pieces.
