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:

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:

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

Hello!

I have been trying to get some replacement parts for my Dynam Turbo Jet and nothing!
Sure you can go to MotionRC-EU and pay almost $90 US for shipping from their location overseas!
Or go to Bitgohobby and pay top $$$ for the parts and moderate shipping from North USA.

I am posting the ON-LINE Help from MotionRC here in the USA and notice that they didn't even suggest Dynam themselves.
Oh, well.....

I am convinced that most of these USA RC Hobby distributors (Except perhaps Banana Hobbies) are pushing these large and heavy RC FOAM models that require 6-Cells and at times 8-cells Lithium Polymer as they are getting a large profit margin on these larger batteries. They make their $$$ mostly on the other items besides the Models themselves. A typical 6-Cell, 5,000mAH Li-POLY battery runs in the range of $95 - $110 from MotionRC (USA) and if you get those "SMART" batteries you will spend upwards of $180 for the 100C discharge at Spektrum.

Both, my Dynam Grand Cruiser and Dynam Citation 550 Turbo Jet only requires a 3-Cell, 2200mAH, 35C Lithium Polymer battery packs and they perform excellent. No need for 4-Cells, 5-Cells, or 6-Cells!

I have seen a few RC Jet and Prop airplane models up at Banana Hobbies that still have models that fly with just 4-cells for Jets but, again it is my thoughts that the entire hobby here in the USA is making $$$ hand over ASHE on these large 6-Cell packs!

What say you?

Guys,

One of my RC Club members brought his shinny new H9 Christen Eagle to the RC Club field and I took video.

One of the other Instructors took the controls for him for the maiden and had a hand full noting that checks and re-checks about the Center-Of-Gravity was performed at the setup table and yes, including the Top Hatch!

Maiden Flight on Tuesday (11-16-2021) at around 10:23am A few points to note:

1. The owner selected the Avian (E-Flite) 100-AMP ESC could not take 8-Cells so, used his 6-Cell pack for the maiden.
2. The model's Center-Of-Gravity point requires the Battery to be slid much further forward than previously anticipated.
3. The 6-Cell pack needs to be placed on its side in order for the Top Hatch to close property.

Summary:
It flew great on 6-Cells instead of the planned 8-cells with the large XOAR Glow 18 X 8 Propeller! Lots of Thrust according to David Rich, the Instructor Pilot behind the controls. However, the model did fly slightly tail heavy and it was nerve wracking at best, especially during landing. A BIG KADOS to David Rich for flying a Bi-Plane in a Tail heavy condition and bringing it back to mother Earth in one piece!

Please check and re-check the Center-Of-Gravity and the owner will have to add a rectangular piece of plywood for an extended Battery tray to allow the Battery Pack to slide in much forward.

Okay,

Now I am totally convinced that the older Lithium Polymer batteries were much better made.

Been flying the Tar out of my GWS Beaver and found a very old but, still capable battery for it!
Beaver is powered by the discontinued Mega 16/15/8-turn Inrunner (Direct Drive), swinging the APC Slow Flyer 10 X 7 propeller.

It is known as the APOGEE 1,570mAH, 2-Cell without any balance plug. (14C discharge!)

Yes, they were once popular back in say 9-years ago!

I have used this battery pack for two (2), six minute flights on the Beaver and it does great after all these years!

Guys!

Wanted to share with you all my successful Paint Match and Touch UP of my tired and very old Park Zone P-47 Thunderbolt "Snorting Bull"

Walmart was my source and found the following:

1. FolkArt Metallic (Silver Sterling) # 873.
2. 3M High Strength Small Hole Repair.
3. High Quality Paint Brushes.

Okay, for this particular model I did NOT use the 3M High Strength Small Hole Repair because there was more scraping on the bottom of the FUSE and other areas than missing foam or holes in the foam. However, it looks like a new wing might help things and I am in the process of finding one.

Here is some pictures of my model after re-paint touch-up and the paint in item (1.) is a DEAD RINGER for the stock paint used on this and other models that Park Zone, E-Flite, Horizon has produced.

Keep them flying!

Guys,

Took my old but, reliable Park Zone T-28 Trojan (NAVY) to the RC Club field and it flew two flights. The first without any issues nor bad effects and the landing was picture perfect. The only observations was that I needed some Up Trim which was very strange as I had never had to touch the trim in all these years. Thought maybe it was something to do with me mechanically adjusting the Rudder Clevis for addition Rudder Authority for knife Edge Flight.

The second (2nd) flight it exhibited some strange looks from the horizontal Stab and looked twisted up in the air, especially with airspeed so, I landed quickly.

At the setup table it was my horror to see that the entire Tail Boom flexed something terrible and the Top Tail Boom FUSE began to separate at the FUSE factory joint.

For those with older Park Zone T-28 (NAVY) Trojans, please be on the look-out for this!

Used Gorilla Wood Glue and it solved the issue.

Hello again, Good People!

This Blog Post is about using today's modern Light Spackle products (in this Blog, I used 3M brand) and Touch-Up Paints (Acrylic) on foam models that are those prized members of our fleet and perhaps more than 10+ years old. This applies to hangar rashes and light crashes as well.

In this example, I am using a model that I recently acquired and learned that I am essentially the fourth (4th) owner and it is known as the E-Flite P-51D Dallas Doll Mustang and customized in German Captured Clothing. This is a good example because the model was customized from the very first (1st) owner way back in 2014.

Here's one post that I found from the First (1st) Owner of this model I am using to provide a better appearance due to time, hangar rash and other issues such as using the wrong type of Paint that damages this foam, for example.

https://www.rcgroups.com/forums/show...STALLED/page94

Okay, I have broken down at

Inspection & Preparation:

Just take your time and look over the model carefully. I observed that the Left Top side of the Horizontal Stab was damaged due to the Yellow Paint "Type" used on the customization for having it look as the German Captured Trainer unit. Also, the Side and Bottom frontal FUSE area (Below the Engine Exhaust Blisters) had the same type of damage of contact with the wrong type of paint.

I found some voids (Foam cells that had too much separation) and indentations (handling & Hangar Rash)...Continue Reading

Just an amazing morning in Central Florida for an Amazing RC Model and it is a crying shame this model is discontinued.

After working on it throughout the night, replacing the Stock ESC to the Castle Creations Thunderbird 36-AMP ESC and touching up on the paint after filling in some void areas on the Foam, this morning I was able to maiden the model on my watch!

Performed just what I had expected after watching my buddy who had one a couple of years ago. It performed Cuban-8's, Hammer heads and some inverted flights. Of course this following Video shows the second (2nd) flight as the maiden was great as well it was recorded in just too low of light.

Oh, yes, the only reason that I changed out the Stock ESC was because it came with a Battery Connector that I just didn't have (Converter).

Okay, here is the Video:

Hi guys!

Whats up?

Been a long time coming and I finally got a used one in German Captured Clothing.

Hey, as the saying goes, beggars can't be choosy!

Hi guys!

Just came across this model at my RC Club and was able to maiden it with very good results.

It is heavy for sure with 12-Cells behind it. Wow!

Guys,

I can tell you that parts for these Park Zone (Horizon) RC Warbird models are getting really hard to get.

I was lucky, however, back in September, I was able to purchase via our Classifieds the landing gear set which included the Strut Covers as my model lost one.

https://www.rcgroups.com/forums/show...Spitfire-parts

I am so glad that I found this sale and quickly acted on it as now my Spitfire has both Strut Covers again!

If anyone has any parts PLEASE let me know!

Took out this large lady of the sky! Had my way with it and flew three (3) wonderful flights!

Leopard RC Motors (LC5065-520Kv) are great as it is powering my large Great Planes RV-4 of 70-inch wing span and tipping the digital scales at 12-lbs. Commutation is done by the Hobby Wing 80-AMP ESC (BEC Disabled) and an external Castle Creations BEC PRO (20-AMP) is used for power to the Receiver (Spektrum AR8000 + SAT). Using just 5-Cells, 5,000mAH, 45C, Lithium Polymer by GENS ACE does a great job on this Glow-to-Electric conversion Project.

Our Bill at my RC Club finally had his maiden flight of his Freewing Al37 in the American Airlines scheme (Custom Paint and Calli Graphics).

We had a few assisting him and the model flew without the benefit of any Gyro or assist from the Stock Electronics as we visited all four (4) Youtube Videos while we were at the RC Club field and could NOT get his Gyro to work so, we flew it without and it performed very well.

However, the Instructor Pilot at the third (3rd) flight reported some very unnerving (unexpected) turns from the model (unsolicited) and he quickly landed without any further issues, thankfully.

The plan going forward is Bill will remove all STOCK Electronic Gear from his Jet and place his well known brand.

Hello good people,

The Modifications for going Servo-Less retracts start at:
https://www.rcgroups.com/forums/show...51D-Mustang%29

----------------------------------------------------------------------------------------------------------------------------------------------------
Sunday morning at the RC Club field allowed two (2) wonderful flights back to back of my World Models P-51D 40 EP Mustang.

There was a slight breeze but, it was steady and no gusty winds.

Was able to record two (2) Flight Videos of the model and the first landing was a complete stall from perhaps 2 feet off the deck and very pleased of these E-Flite 15-25 size retracts being able to take the punishment and of course the low bounce rubber scale tires. If these were the stock mechanical retracts I would be replacing the mechanical servo as it would have stripped by now.
In any case, here's the videos:

Okay guys.....

After some additional tinkering around with the mechanical retracts, I gave up and decided on E-Flite 15-25 size E-Flite Retracts. The E-Flite Retracts were bought from eBay a few years ago and finally took the initiative to change them out on this World Models P-51D 40 Mustang.

A few things to keep in mind and items you will need for this modification:

1. Dust mask and Safety Glasses, no kidding please wear a pair.
2. You will need heavy duty wire cutters.to cut the ends of stock slightly bent wire struts.
3. Dremel tool on the lowest speed setting, in case your Dremel accidently touches the covering.
4. Using Dremel - sand away both sides of stock attaching mechanical retract plywood rails and square off opening of retract cavity.
5. Fit check the E-Flite 15-25 retracts and repeat step 4 as required.
6. Feed in a 6-inch or 12-inch servo extension and connect to E-Flite 15-25 retract.
7. Once the E-Flite 15-25 retract stays flush on the wing opening cavity, check for function and see if retract wire enters the cavity.
8. If not, repeat Step 4 as required.
9. Use a drill with the appropriate size (depending size wood screw) and drill holes for securing E-Flite 15-25 retracts.
10. Repeat Step 7 before screwing in anything yet.
11. Using Dermal tool, Dremel a FLAT Spot on the stock strut wire so, it will not rotate and provide a secure fit when tightening set-screw.
12. Once you are sure all is functioning okay, use appropriate screws and...Continue Reading

Hello fellow RC Modelers!

Today I came with a model that I have had since late 2008. It still delivers the manners of a terrific and super light P-51D Mustang (Gun Fighter) RC Model. The maker is World Models and the USA distributor is Airborne Models in Livermore, California. Believe it or not this model still is sold by Airborne-models. This November 2021 will mark 13 long years of service of this model with me and every time I take it to the RC Field and it never disappoints. Almost 50-inch wing span with extremely light wing loading the Mustang model can be flown true scale like and landings are majestic. Sharing a super nice video from a nice Tony Speed who was a member of our club a long time ago. Also, sharing today's pictures of the model "at the setup table" and as you can see it is still in very good condition. The other pictures (in-flight are from almost 13 years ago!)

Hello good people,
This Great Planes Kit has been discontinued for a while now and someone had started it and just left it sitting for a number of years. The owner must have passed and the nephew got it and sold it to me on the cheap!
Since it has been started and partially built, I can't provide any building tips of any kind.
Thursday was a big day full of work and personal errands and at first I promised myself that I was just going to look at it and make sure all parts were there and see the weight of the model and how much TLC (Tender Loving Care) I need to give it. Well, the gentleman (Mark) was super friendly and allowed me to look at it carefully and I took out all parts from the box and made an inventory and verified that all critical parts was present. I knew that he was not the one who partially built it because he didn't know where the Wing Tip sections was all about.
I gave him his asking price at $100 Cash and he helped me load my car with this rather monster of a Prop Jet.
I am not fooling myself as this will be a heavy model, however, I have seen the videos (Youtube) about this model both in Glow & Electric (Prop Jet) and it has one of the best manners you can dream of. Can't wait to finish this and going to setup it with the ALL WHITE with the Rising Sun logo at the Tail with Shark Teeth up front. I may consider the NAVY BLUE Angels. Anyway, It will look terrific and I know it will fly fantastic per the videos. An un-started kit goes for $300+ and I was...Continue Reading
