I haven't flown in over a year. Nearly a year and a half. Why? Because I'm in the National Guard, and I've been tied up on the weekends. Also, our club field has been under construction for over a year (county project), and coupled with the fact that on the weekends I don't have drill, my wife has either had me traveling with her or doing honey-do's, or the weather hasn't been conducive to flying. So, here I am: severely out of practice and longing to get back into the air.

I did get a DJI Mavic 2 Pro yesterday, and despite the high winds (gusting to 20 mph), I was able to get it up into the air and get some nice video footage. I can see now why these drones are both so popular and possibly dangerous; they are ridiculously easy to fly and require very little skill. They do get some amazing footage, though, and I have to admit that I'm really looking forward to some trips now with this drone.

I'm probably one of the very few who has my FAA, AMA, and contact into actually on my drone, but I figure the last thing I need is to have something bad happen and I run afoul of the law or the AMA. Anyway, I hope to be able to get back into the air soon with my beloved warbirds. I miss flying them dearly.

I'm sure that this situation happens to a lot of people, that is the Lipo battery is dead after it used a few times. And users' first reaction must be that the Lipo battery isn't good enough. As long as you buy a reliable brand, as long as you use the Lipo battery in the right way, the Lipo battery will last a long time.

Let's start with what might kill the Lipo battery:

The 1st reason: It is not correct for Lipo batteries to store at full power or no power for long periods of time. If you don't use your Lipo battery for a long period of time, such as 1 month, 6 months, or even longer. Then proper handling way will ensure that your Lipo battery will be good in storage.

For Storage, take note of the following:

(1) In general, we recommend that the customers store the Lipo battery at half power. And the temperature of the storage environment is about 25 °C.

(2) Before storage, charge the Lipo battery for the last time. Check the voltage of each Lipo battery cell. Make sure that the Lipo battery cell voltage is almost the same (error + /-0.01V). Then discharge, release about 50-60% of the power, and then save.

(3) If the Lipo battery is not used for more than 1 month. Then check the voltage of each Lipo battery cell regularly every month. To ensure that the lowest battery voltage is not less than 3.0V, if less than 3.0V, then try to charge and discharge again.

The 2nd reason: Many users always overcharge or over-discharge their Lipo batteries while using

I only had one 5x3x3 prop to try on the Mini Surfer 800
Today I got a package with some new props ..
So of course I had to see how much current they pulled .

I recently just purchased from a guy. Back of strut is worn looking and missing teplon bushing. When I take off prop seems a little too loud? Until it planes out! Also it didn’t want to stop doing circles after about 10 mins. Prop wouldn’t straighten out until about 2 mins later

Look at the picture, this picture is amazing once you figure out what happened. The "T" in the top left of the picture is the scope trigger point, ball at rest (0 rpm) 25ms later, the ball is at 3.2 million rpm!

I always set the vertical cursors to my current record (in microseconds), so I can see when I beat my personal best.
I usually prepare 10~15 balls for testing that day, one day, I got to this one ball, I guess things were just right (ball/container/angle/settings). What happened was amazing and unbelievable, with about ~250W (18V ~13A). First hall sensor trigger, it gave a ~0.25 second burst, I could hear the power supply give a quick 60Hz hum, sucking some juice, then the scope displayed high 2 million rpms! The major keys it was legit was no vibrations and the ball was still spinning down from momentum. I have been running the scope at 10us/div (since going for 2+ mil), but I decided to get the big picture, zoomed out the scope to 100ms/div and set single trigger and tried again, moved the hall sensor into position and it happened again, a burst of around ~250ms then hall stops triggering the coil. I zoom the scope into the end of the coil drive signal, this time just over 3 million in a quarter second! I stopped to think about it, no Ford transmission vib's, just pure signing spinning ball. Blown away I called a friend to witness what happened, I did it 4 more times, the most impressive time was in the picture, it shows 0 rpm to 3.2 million rpm...Continue Reading

I've had this F4F for a number of years now and although it has never been in a major prang it did need a bit of a refresh.
Beside, my eyes just ain't what they use to be and the blue grey scheme was getting difficult to see.
Time for a prewar dress up.
Much easier to see now and IMHO looks a lot nicer too.

I built this out of spare parts and left overs from old planes.
No dollars were wasted on this build because none were spent.
The wings and tail are modified from a Phoenix 1600mm glider that a fellow club member had rammed into a lighting tower.
Fuselage is made up from 15mm thick blue foam which was salvaged from some packaging material that I found at work.
This was then covered with 30gpm tissue paper and painted with cheap rattle can enamel.
Retracts came from a Durafly Corsair and were pinned to stop them twisting 90deg.

Flies really well. Quite quick and only needs 1/2 throttle for most flying. Very maneuverable and slow flies well. Take offs and landing are a breeze.
All round this is a rather pleasant plane to fly at any speed.

Wingspan: 1125mm
Weight: 1205grams
Motor, Turnigy 3536 1250 Kv
Prop: 9x5
Battery: 2200/4s
Servos, 9g with the elevator being metal geared.

I have an ancient Telemaster 40 that was for sale. It wasn't getting any serious interest. So I stripped it down of all of its monokote/econocote. Whatever it was it took about 15 hours to get to bare balsa. I used an Xacto, packing tape and Scotchbrite pads. Time consuming. No wonder it's a job most avoid. Hunting cool color schemes down. May just go with stock red and white. It was a Hobby Lobby plane. It has builder markings in it.

After flying my Blade Nano S2 enough to wear down the performance of the stock, brushed motor, I decided to install Horizon Hobby's brushless upgrade, BLH3325, into the S2. I chose to basically copy the install posted by HF member, Chris1683 in the HF thread, Ideas about brushless upgrade, because, well, it seems like the best way.

As many nano-enthusiasts will attest, keeping the weight of the nano as low as possible is an important factor. The weight of the nano can affect everything from tail hold to flight time, as well as climb-out and flipping performance! Before the installation, I weighed the S2 without a battery. The scale waffled between 26g and 27g, but seemed to settle on 26g, as shown in Fig. 1. I decided to pull the HH brushless motor and ESC from my Nano CPS since I knew that they would add only about 2g, overall.

One key to keeping the weight of the brushless upgrade on the low side is getting rid of the connectors that come with the upgrade and shortening the wires as much as possible. Of course this makes soldering even more difficult, and it's not easy for me to see such small solder points. I almost felt like I was soldering blind!

As shown in Fig. 2, I removed the brushless ESC from its shrink-wrap and then soldered on new, slightly thicker wires. The only decent place to mount the ESC is on front of the receiver board, and the stock wires were getting in the way. So I removed the stock wires and soldered the thicker wires to the...Continue Reading

I have a FeiBao 1/7 scale F-5 for sale

. I set up the jet as a 120mm EDF. I still have the split Turbine pipe, fuel tanks, intakes and small other items to convert back to Turbine.
You will have to install wood mounts to install your Turbine. The front nose wood mount needs fixing (ran off the runway into the grass )...Daaaaa
Comes with a 9ch X spectrum receiver. The flight stabilizer is an Eagle tree guardian. Air Breaks and all the servos
I used a 3 cell 2200 for the BEC Pro receiver power and two 6 cell 5000 battery packs to fly it.
The jet WILL NOT come with the 120mm EDF unit or the 160 HV ESC.

I will take $1700 for it, I have Paypal. you will have to pay for boxing and shipping or pick up in KY zip 40160.

I am starting a new project and the Boss said "Clean out the hanger".
I am King of the castle ,,,,,, when she's not home.....

Feel free to PM me for any questions and photos.

Thanks for looking.

After working through some of the kinks with the FT Simple Cub, I managed to add another kink by bending the prop shaft. I had actually never done that before. But I guess all that lawn darting can lead to it. I didn't even realize it had happened until I had done some repairs and was ready to fly it again.

Got this kit from sunset models as a shrank down version of the 120 kit. The stick sizes weren’t scaled down to standard size so 3/8 spruce was just too small for spars. 1cm carbon square used instead. Wing is SOLID so far.

A while ago (2005) I build this catamaran with 2 Phoenix 125 speed controlers and 2 Graupner inline 700m 24v. brushless motors.
The first time I went sailing, the 2x 16 NiMh cells melted!
So i parked the boat and recently i dusted the thing and decided to try again.
I bought 2 LiPo 6s 22.2v 5400Mah and tried my luck... and failed. Again.
The double speedcontrolers where fried while testing the motors and setup.
Now i need two new speed controlers who can stand the heat, abuse and the current.
Can anyone give mee advice?
I would like to enjoy this boat and stop putting money in this project.

Trying an other hobby is not the answer i expect :-)
