Okay,
As I type this tonight, there has been many USA distributors that have discontinued the Dynam line of RC EPP Jets that operate on 3, 4-cells with great results. It is my thoughts that it is perhaps the bigger picture to get more profit margin by the introduction of the larger and heavier EDF jets. These newer EDF jets require 6-Cells and capacities now range into the 5,000mAH (5.0 Amp-Hour) Lithium Polymers.

Hence, my beloved and discontinued "White" Dynam Turbo Twin 64mm EDF Jet that operates with just a 3-Cell, 2200mAH, 35C, Lithium Polymer still is operational today and I was lucky to find a true gentleman who sold me some hard to find parts for my Dynam Turbo Jet. (Picture attached).

A few have contacted me saying to provide a video showing the performance and most importantly the landing of this very nicely designed EDF Jet by Dynam so, here it is:

Das Ugly Glider - Part 3

Very productive day...and very pleased with the weight...got the fuse assembled and dry fit the tail section...I'll be darned if it doesn't look like a little Ugly Stik...The Tab-A-into-Slot-B method made the assembly so easy...I guess I'll start on the wing tomorrow

Hope everyone had a great week. Our family met at Grandmother's house in Arkansas, she has a 10 acre field which was very nice for flying in. Wish I had brought more planes!

The left motor went to valhalla while slinging the DSLR 10 miles. Thus another day went to rewinding a motor with 20 turns of 26 AWG. The PETG motor mounts are taking the heat nicely, letting motor after motor fry. The retaining ring was documented to show future lion it was properly reinstalled. Those retaining ring pliers have proven essential.


Some notes during the replacement were crash damage to the bottom panel. The 1.6mm tread tire still delaminated. The next step would be 250C printing, but delamination doesn't seem to have any impact unless it picks up a branch.

Piggy backing fets has been done by many. Link shows XP-3A as an example.

https://www.hacksmods.com/2012/04/ho...brushless-esc/

Pic is one I did for Genius CP around 2012 2014. Most recently did a MX-3A.
Posted by BlRDMAN | Yesterday @ 01:28 AM | 6,136 Views
I believe this feature of the MX-3A ESC is unknown to most. This esc in its stock form is programmed to accept pwm input of 1kHz, 2kHz, 4kHz and 8kHz with a simple modification. Simply add R1 and R2 resistors (form a voltage divider), value is 1K, size is 0402. This size resistor is "small" but can be done with most ordinary iron with a sharp tip. I have soldered many components this size with a dirty old 40W Weller soldering iron.

Hint, find any copper rod, rivet or similar of correct diameter to fit your iron and sharpen to a point, round point ever so slightly. Clean and tin as it heats up.

Cheers

After being discontinued, I got lucky and feiboa still had the molds to build me my favorite jet of all time. This is the actual jet, I got lucky a second time when they also had a pair of retracts still available....Continue Reading

Thanksgiving week here in the north east and for the second week in a row I was able to "double dip " and get in 2 flying sessions in one week

Tuesday started with a couple of inches of fresh snow and a forecast of 15 mph winds and 36 degrees - Perfect to get a old flying buddy who had moved down south and was back in town for the holidays out for some fresh air....and get some stick time on a good combat wing {His current slope plane is a Goldberg Electra }.
I downloaded the Knife Edge model from my radio to his and out we went,I knew it would be a good day,my buddy the red tail hawk circled us as we walked up the hill .
The wind at the top was less than predicted and vectoring ,not the greatest conditions especially for a newbie ...
I launched and trimmed the wing , flew around scouting the lift and showing him how to search and cruise.
These Knife Edge wings are very efficient , if allowed to run they will slice thru sink and climb in even the lightest choppy lift that we often have on our hill as the wind vectors around.
I handed him the transmitter and coached him for a bit,after a couple of minutes he was doing well by himself so I asked if he was good with me putting my plane in the air,he said yes so I jogged back to our gear and grabbed my plane hoping he would still be in the air when I launched .
No problem - he was doing fine and enjoyed the game of hide and seek as the lift ebbed and flowed around and out in front of the hill .
After about...Continue Reading

Guys,

Just could not wait any longer for parts so, what did I do?

I went to work on my beloved Turbo Jet and fixed as best I can the Frontal Fuse area using 1850 Watt hair dryer, White Glue, and Spackle by 3M.

Hair Dryer took out the largest dent on the nose and white glue placed the two halves of the FUSE back aligned and even.

Also, replaced the Nose Retract, wheel and it steers like new!

I could not believe how well the Jet flew this morning!

Zoomed like a home sick dove!

EDIT: That bump on the frontal nose was there when I purchased it from someone in Central Florida and you can see the For Sale Ad here:

The most common problems seems to be with LiPO or lithium batteries are with e-bikes fires but not limited to e-bikes. The bigger the device or battery the larger the risk.


I got to say the most scariest part of owning LiPO batteries besides the fire hazard is the fact that I ride the elevator up and down with those batteries while you're temporarily trapped inside the elevator until the door opens. I know there are some safeguards for elevators but that's more for not the elevator stopping on the floor that's on fire. If my battery is going up in smoke while I am in the elevator is the elevator going to stop and the door open or am I going to just have to ride it out. I'm guessing it will stop and open the door. It can happen in my vehicle too but I can stop and get out.


This is not fiction. This stuff actually happens and yes people get burned buy lipo fires and harmed by smoke annihilation and sent to the intensive Care unit. And yes some people do die.

I'm more afraid of the smoke myself cuz I have gotten my wiff of that smoke and it was bad. Wasn't trying to smell it but just was the lingering effects of the aftermath during a damaged lipo fire test outside in a completely open outside area.

I keep my batteries outside so not too much a problem as far as smoke damage indoors. That is if windows and doors are closed neighbors included.

Just thought this was worth mentioning although there's going to be some who wish I didn't. I don't care about them. Greedy bastards.

Well, guys....

My luck is just amazing lately.

A few days ago, I locked in on someone selling a BLONDIE locally and I grabbed it in short order!

It just needed a little (very little) TLC (Tender Loving Care).

Overall the Eye Candy is there and looks like new after cleaning the model and Filling some dents (hangar rash) and touching some areas with paint.

A few pictures of my new to me BLONDIE!

Maiden Summary:

This model does okay in the airspeed department, however, it is a little too light and gets bumped around a little with some wind, however, the landings are just amazing such that I was able to land it for three landings with KISS-THE-GROUND effect every time many came to ask, "What Model is this?"

It is a keeper!...Continue Reading

LiPO batteries are common. They used in cell phones and computers and electronic devices as well as our RC devices.

The LiPO batteries used in the RC industry often don't have the kinds of protection that the cell phones and other device batteries have. Don't compare the two cuz they're not the same. Yes cell phones do catch fire but not that common.

It is well documented that lipo batteries are a fire hazard. Lithium batteries also. Life batteries not as much. HOBBY STORES, LIPO LITHIUM BATTERY FACTORY, HOMES, VEHICLES AND MORE HAVE BEEN DAMAGED. Yes they have been deaths also. Unfortunately the dead can't tell you about it.

The advice normally is do not store batteries fully charged because they are at a higher risk of catching fire.
DO NOT STORE (keep) DAMAGED BATTERIES.
Do not store batteries in an area where materials can catch fire and smoke damage can occur. LiPO fires give out a huge amount of smoke and yes it is harmful if not lethal. So do not inhale. Not only does water not put out Lipo fires but can actually cause a LiPO battery to ignite. Charged Lithium metal will ignite in water. Sand is a better alternative. Water can be used to put out some other materials that have ignited, but not all.

Batteries that are at storage voltage of 3.8 volts per cell still can catch fire but are at a lower risk of doing so. Try not to get confused with stored and storage voltage. Stored is the location. Storage voltage is the state of batteries charge. For...Continue Reading
