It's finally finished! The ultimate 1.3 Video Ground Station! TrueRC Gatling and Singularity on a ServoCity Tracker with EagleEyes for control and diversity, 7" monitor, 5.8 relay, Power Switch, E.T. PowerPanel for displaying GPS, and one switch to power up and start recording on the FPV-Japan DVR - which is powered by the onboard 8000mah 3S Lipo! All housed in a custom built CF and ABS box.

Also included are pictures of my original Ground Station, which used all the same components except the tracker, and some of radios....Continue Reading

Ranger EX Thrust Angle Issues
Posted by Sweetieinsf | Dec 02, 2014 @ 02:27 PM | 9,884 Views
Volantex Ranger EX FPV

Equipment - Air Frame
1) Volantex Ranger Ex PNP version
2)FMS Main Wing Multi Connector parts 1 & 2
3) 4 Hobby King Digital Servo 2.2kg / 12.5g / .11sec (Ailerons and flaps)
4) Stock 1000kv motor and 10X5 prop (soon to be replaced with a Turnigy 3542 1250kv)

Mods - Air Frame
1) Spread the Main LG out to ~ 12" between Tire centers and added a bit of Toe-in for better ground handling
2) Used Gorilla Glue and Foam Tac to glue the two main wings halves together for increased strength. (Gorilla glue for the main wing spar, Foam Tac between the foam halves).
3) Added two strips of fiberglass reinforced tape to the bottom of the main wing for improved strength
4) Re-hinged the rudder and elevator using plastic pinned hinges
5) Applied hinge tape to the top of the main wing to reinforce the flaps and aileron hinges
6) Replaced the stock aileron and flap servos with digital metal gear units
7) Installed FMS P-51 Wing connectors on flaps and ailerons to ease wing installation and removal for transportation.
8) 65amp FMS ESC (from the parts bin after I upgraded the P-51 to a 100a CC ESC)
9) Added a washer under each of the two lower motor mounting screws to increase the down thrust. This, along with flying at 70mm COG, has greatly improved this plane's tendency to climb off throttle and dive at full throttle. If it were not for the fact that It would complicate things flying with the ET Vector I would long ago simply programmed a...Continue Reading

Today I once again saw a post regarding LiPo battery charging and since I always seem to see these kind of questions from NOOBS (remember we all were once!) I decided to post a clear reply. Once I got started my response quickly got into my usual method of charging multiple batteries, Parallel Charging. When I bought my first Parallel Charging Board from Hobby King about a year ago I was ASTOUNDED that it arrived with ZERO INSTRUCTIONS and quickly realized that this thing was a recipe for DISASTER in the hands of the average person. I did lots of research and found very limited info on safe practices of parallel charging but over the last year I have leaned a few things and have had excellent results charging multiple batteries at the same time. Hopefully this prevents a few disasters and makes your battery charging just a little less of a hassle.

Q: Hallo to everyone,
1 question ... I have a IMAX B6 charger and I need to know what is the best current (Amps) to use for charging the 5200 mA battery of QR X350 PRO. For now I have used 1A ... Can I set to 2A with no issues ?
TIA


A: All modern LiPo batteries can be safely charged at 1C (one times the "C"apacity rating). In this case the C rating, or capacity, is 5200mah or 5.2ah so you can safely charge these at 5.2 amps. For longest life always BALANCE CHARGE them with a quality balance charger.

In my case rather than charge each battery one at a time (I often use six or eight batteries when I go fly) I...Continue Reading

It seems I am always getting asked about my FrSky setup and since I am in the process of a rebuild due to a bad crash I thought I would document my FrSky setup for the benefit of others.

My goal is to fly FPV to a medium range (1-1.5 miles) to video interesting sights around the San Francisco Bay Area that I have been unable to reach with my C-47 fixed wing FPV rig due to a lack of takeoff and landing spots.

My equipment consists of:
FrSky Taranis Transmitter
FrSky D8R-XP Telemetry Receiver with battery voltage sensor
Boscam HD19 Camera
Boscam 500wm 5.8Ghz Vtx
Boscam LCD display with built-in 5.8Ghz diversity receiver
A variety of RHCP antennas

With the above setup I have flown in excess of 5800 feet with no loss of video or control link.

The first steps are to install power taps for the Camera/Vtx and the Voltage sensor that will give me live battery voltage readings on my Taranis as I fly. Also since I've confirmed one crash due to a loss of power to the receiver and the Devo-M FC I will install a 3amp UBEC and remove the leads from the on-board voltage regulator (BEC). Conveniently there are three 12v taps on the power board:

Next is the receiver connections. I am using (and highly recommend) the FrSky D8R-XP for this application. It is a bi-directional telemetry receiver and offers two distinct advantages over other FrSky receivers. With a jumper on the signal pins of channels 3&4 it outputs CPPM on channel 1 and RSSI on channel 2. CPPM...Continue Reading

I've begun installing Carbon Fiber Crash Proofing in my Hellcat. So far I've completed the vertical stabilizer, horizontal stabilizer, cowl, and fuselage. I'm waiting on more CF rods to do the wings.

Click on the pictures for descriptions/notes. Hope this helps!

I will update with pictures of the wing crash proofing as well at the LCLander install when I get to them.

A BIG thanks to Max at ParkRCModels.com for his EXCELLENT Customer Service in getting these units to me for this review!

First watch the video, Comments after!

RCLander 100 deg All Metal Retract Quickie Review (11 min 27 sec)


I found these units on the RCLander web site and finally found them available at ParkRCModels.com. The owner, Max, was EXTREMELY helpful in answering my questions and shipped them to me US Postal Insured Priority Mail at NO CHARGE!

According to Max "We bench test everything before we ship - we won't ship anything we won't trust to fly ourselves - HOWEVER factory defects do happen - even after some use - We have a very liberal return for replacement / repair / etc policy directly from our Michigan USA warehouse - if it stops working and it has not been because of abuse or buyer mis-adventure or a crash we will generally replace it if it is from a defective or factory defect - we are more expensive than HK - however most of our products have shipping included ( orders under $20 - $3 low order fee) AND extraordinarily large cartons like our planes and jets and larger helicopters do have a actual shipping fee"

Considering the free shipping, the bench testing, the GREAT Customer Service and Warranty Policy, AND the quality of these units I was happy to pay the $69.95 price.

Once in hand a quick assessment as to the suitability of these units as replacements for the cheap Dynam gear lead me to these early conclusions:

When I got into this last year who would have ever guessed I'd have *24* batteries in 6 months?!?! Certainly NOT me!

When I bought my 3rd battery I started numbering them with a Sharpie in the order I bought them. I also started writing the name of the plane(s) I'd specifically checked that battery in for COG. Also for most planes I'd use a Sharpie to mark a reference point on the battery and then when I was happy with it's placement in the plane I'd make a corresponding mark in the battery compartment of the plane.

All was well until the number of planes, and batteries, increased to a point where memory just wasn't good enough. For one thing the Sharpie marks would wear off so I couldn't read them. So I finally sat down with ALL the batteries and put a strip of masking tape on each one then marked
  1. The number
  2. The MAH rating
  3. The "C" rating
  4. The Cell Count
  5. The name(s) of the planes it had been COGed for
  6. And any referance marks for the specific planes

THEN I covered the masking tape with shipping tape so the marks wouldn't wear off with continued use. I also have several LiPo Charging Bags that I store them in - each bag labeled by cell count:

Purchased 4/5/13 from MotionRC.com
Assembled 4/12 - 4/14/13

As of 5/15/13 I have not yet been able to fly her. It's been way to windy and so I continue to improve my flying/landing skills with my Dynam F4U Corsair and Dynam F6F Hellcat.

I haven't made to many modifications but I did:
  1. Install the FMS 1700 P-51 Wing Connectors
  2. Added a 5A UBEC
  3. Replaced the stock Gear Door Sequencer which required the replacement of the stock REVERSED (What's up with that FMS?!?!?) Gear Door Servos
  4. Slightly modified the battery tray and cover tang to allow for a 4200 45c 4S battery

Also since I fly from a pretty rough field I've been meaning to replace the stock strut springs with something a bit softer...

Although I found the Dynam Hellcat easy enough to land I thought I'd go ahead and install flaps since she is "Flaps Ready". Because I could find only one example of a flap mod on this plane (and I wasn't that sold on that setup) I decided I'd just go the route that seemed easy and effective. I used all stock Dynam parts:

6 - flap hinges - http://www.graysonhobby.com/catalog/...ck-p-2117.html
2 - stock Hellcat control horns - http://www.nitroplanes.com/60p-f6f-12-servohorn.html
2 - stock servos - http://www.hobbypartz.com/60p-dy-1007.html

Also needed is a servo reverser or put each servo on a separate channel. Since I had a cheap reverser I went that route. Depending on the servos you use you may also need a couple of servo extension leads. With the stock Dynam/Detrum servos I had on hand I needed about 300mm extensions (which I've ordered since I had none that long in stock).

In these first two photos you can see I've completed the flap install on one side and this will be the goal on the other side.
