A few months ago my GWS pico Tiger Moth sustained an ugly Right Wing Crash because I erroneously took out almost all of the wing dihedral and was stupid enough to hand launch it and it slipped into an inverted flying position. Fortunately, I was able to recover it in time and had the model flying right-side UP again but, the landing was not good and Right Wing ripped.

My efforts of gluing it back was amateur like by leaving the wing in a position while glue was curing that caused some sort of wing distortion (Wash-In) instead of Wash-Out, definitely the two wings not matching for sure. I made sure that the wing dihedral was placed back by gluing an Aluminum short Tube at the bottom of bottom wing, however, during in-flight observations, the Tiger Moth was observed to stray (slide) to lean towards the Right (a gentle stall) while mid-flight. Correcting this was no issue by applying a slight down Elevator and of course a tiny amount of Left Rudder.

However, all of this has caused me to re-think things as my Tiger Moth is no longer "Hands-Free" type of flying and you have to watch it carefully. I have taken steps to correct the Wash-In and settled using some home made tools (Large Clamp with heavy magnets) to pull down the rearward bottom Right Wing to at least match the Left wing.

No guarantee of the results but, I just hate breaking up the bottom Right wing again to provide the correct amount of Wash-Out and the glue etc...

Everyone that has seen it fly recently with this wing issue says it still flys majestic but, guess who has to correct at the controls!

For Part-2 then, go to:


Work got in the way, as usual and some family obligations so, for two (2) nights I have made some slow progress to finish up that Top Hatch and ways to secure it.

First, I had to make planking frame around the Top Hatch cover itself to provide some rigid strength and so the same with the FUSE side.

Just a lesson learn here that you would want to glue in the End-Cap formers at the FUSE end (both sides) before you proceed in cutting the underlying Ply platform which is right underneath the Top Hatch Cover. Why? Because the factory only provided a thin and weak end-cap plywood formers and when you start sawing these just come unglued but, not to the point of any damage but, still just a heads UP.

At time of this write-up I have finally figured out a way to secure the Top Hatch cover to the FUSE by using some lose magnets from a Park Zone 480 Brushless motor and at the FUSE end a machine bolt with a large metal washer. I have not tried it yet because the glue that will hold the magnets is presently curing.

Okay, I am tired so, here's some pictures of my rather slow progress less the magnets.

To flow along from the beginning then, go to:

Okay, cutting away for a Top Hatch.

You know that just because I am an Electric RC Flyer doesn't mean someone that decides to go with a Gasoline Engine would not benefit for having a TOP HATCH because as one of five (5) instructors at my RC Club, I have seen the Tank Valves close by the tank and at times things (tubing) and other items need access and let me tell you, the only way to reach into for anything in there is by removing the Wing Assembly as this model was built in this manner.

Oh, I am NOT the first in making a TOP HATCH on these models! I was guided by others with a smaller size Sparrow Hawk and someone else with the same size. Here are the Discussion Threads in case anyone would like to follow them in their methods.




Very first thing I did was to use a similar size Lithium Polymer Battery and inserting it inside the FUSE to see how much relative space I needed for the 6-Cell Lithium Polymer battery packs. Using a stiff and rather old Tape as a Guide and using Push Pins, allowed me to really finish the cut-away for the Top Hatch in short order! The Push Pins allowed the initial guide for the application for the Tape and this was how I marked up the Top FUSE for a Top Hatch cutting session.

The rather stiff and old Tape that I used to...Continue Reading

Hello good people!

Yes, calling this a Glow-To-Electric Project because this model was built and designed for a large 62CC Gasoline Engine (almost 4-lbs. of Engine with muffler), even though it is new from the box and never seen any fuel or Internal combustion Engine hanging from it.

I have had this Model, the Seagull Sparrow Hawk 62CC (85.4-Inch Wing Span) in its super large Box for almost eight (8) years and one week ago today, finally took it out from the box and threw the large box away so, there is NO TURNING BACK!

Here's when I purchased it new-in-the-box:

I am progressively working on it and mainly acquiring the Power System, servos and other components that I have been carefully selecting to make this project Electric Powered.

Okay, for the power system I was lucky to find a used and in great condition HACKER A60-5S (295Kv) and coupled with a Castle Creations ICE 100-AMP ESC over at:

The Power System was bought from a gentleman that is a member of the On-Top-Of-The World RC Club, Ocala, Florida. As a matter of fact they are having a FUN-FLY on October 30th, 2021 (8am-5pm) and their official web site is:
His name is Gary who sold me the power system was very helpful and gave me assurances that this power system will fly my large SEGULL Sparrow Hawk 62CC of 85.4 Inch Wing...Continue Reading

The selected power system and prop selection was perfect. I did go to GravesRC (Hobby Shop) here in Orlando, Florida and purchased a brand new GENS ACE 5-Cell, 5,000mAH, 45C, Lithium Polymer as they were on sale plus two APC Propellers. One propeller was the APC 14 X 10-E and the other APC 14 X 8.5-E of which I selected the APC 14 X 8.5-E and it flew just magnificently and was mostly 1/2 throttle and when I increased to two (2) clicks above 1/2 throttle that motor spooled up and you can hear the propeller cutting through the air.

Very pleased on the Vented Spinner as it is very well balanced and didn't exhibit any vibrations or ugly noise coming from that business end.

At one point, I tried to slam the throttle and kicked in some rudder and up elevator and this RV-4 almost behaved like a 3D with a few snap rolls. I didn't attempt another one of those and glad I was UP 5-mistakes High!

Without any further delay, I will be sharing the Flight (Maiden) Video, thanks to Gerry Rivera who recorded it and along with the Still Pictures during the 2nd Flight.

Purchased a new digital weight scale and have updated the model's total flight ready weight!

Previously, took some erroneous weight scale measurement from a tired digital weight scale and the digital weight scale with fresh batteries announced...

Model with Power System Battery (5-Cell, 4,000mAH) = 13 lbs.

Correction: 11.2 lbs. total flight ready with Power System Battery!

Due to this detail it is now a better outlook for Watts/lbs. and other parameters.

Changing nothing, the parameters do indeed improve and Stall Speed went down to 25-MPH instead of 28-MPH. Not splitting hairs here but, that amount of weight that is not on the model does matter. As a matter of fact every ounce matters.

So, went back and performed two Prop-Calc "estimations" and yes, later I promise that I will perform Static Actual WATT-Meter measurements. My main goals is to keep the AMP (Current) draw as low as possible so, I can fly the model for at least 5-minutes. Going with anything higher in Pitch such as 14 X 10 increases the AMP to 61-AMPS and reason why I am considering the APC 14 X 8.5-E instead.

Hello fellow RC associates.

Hope everyone is doing okay and staying safe.

Just sharing this news cast about people with Jamming devices, though not frequent but, still out there creating an unsafe environment for Public Safety communications, WiFi networks and of course potential and disastrous situations for our RC Hobby.

I am not understanding why-o-why someone would modify or operate any RF transmitting device that would place many in harms way via their actions by operating a device such as this but, they are out there. There are places right here in Orlando, Florida that I would not consider flying any RC models as I am certain people have engaged in this behavior and endangers any RC model with these Jammers and I have personally witnessed myself crash events (at a certain location that many fly their RC models) that had the potential of great bodily harm or property damages (a little larger than a park flyer) due to complete Radio loss.

Here is the news article:

I am now taking careful steps to Range Check all of my models carefully prior to take-off but, the facts are pretty obvious that once in the AIR and a Jamming device is turned ON, the potential of losing a model is high due to the low power of our Radio gear.

Stay safe!

Where it all started!

Great Planes RV4 70 inch wing span a Glow-To-Electric conversion Project.
Okay, I got this model back in January 12th, 2021 for a cool $80 Airframe Only (came with Switch & Harness, Fuel Tank, and Ignition wires plus all push rods in place.

I am Finally making some progress on this large lady of the sky. Got the brand new Power System installed and Electronic Speed Controller, Propeller (APC 14 X 7-E) and Ventilated Spinner. Need to populate the model with servos and external Battery Eliminator Circuit (BEC).
A few pictures of my progress and notice that the Fuel tank still had fuel in the tank!

I did run UP the motor for the very first time using Admiral 3-Cell, 2200mAH, 35C Lithium Polymer (Fully Charged) and wow, it has lots of power even with the 3-Cells. I might just be able to fly it with 4-Cells. I was pleasantly surprised how well balanced that inexpensive Ventilated Spinner performed....Continue Reading

After taking out the power system from my beloved Tower Hobbies SPORT 60 Electric RC Airplane model to power another project, I had missed this model something terrible so, I ordered the same exact Power System and finally last night I re-installed the power system to my SPORT 60 and ready to fly it soon! This time around it will fly with the XOAR 11 X 6 Glow Propeller and a ventilated spinner. As always, it will be powered using 4-Cells, 4,000mAH, 35C, Lithium Polymer Battery Packs.

Power System Specifications:

Emax BL-3520/6 (840Kv)
Hobbywing 60-AMP ESC
XOAR 11 X 6 Glow Wood Propeller
GEMFAN Ventilated Spinner (Plastic) with metal Back Plate

Okay guys!

Got my Hangar9 F-22 Raptor converted to Electric RC airplane model back in the air for two wonderful flights after one year and two months hanging!

Just an amazing Sunday Central Florida morning! Performed the touch test after each flight on the motor and I was able to keep finger on motor rotating can so, it was two good flights without motor getting too hot on 5-cells.

Loose magnet was repaired one year ago and Gorilla Clear Glue operational temp goes up to 180 degrees F. Therefore, after two flights of 7 minutes each with spirited flights, I am declaring a success with repairs on Motor!

Repairs on motor can be seen at:

Video post improvements on my H9 F-22 Raptor:

Amazing model!

Well good people, came with something different and not available anymore (discontinued for a number of years). I got this from a friend (David McCullough) a few weeks ago. It is the ElectriFly GEE BEE of 38.5 inch wing span and tips the digital scale at 2lbs.-1 1/4 oz. with the 3-Cell, 1800mAH, 30C, Lithium Polymer battery pack. The Center-Of-Gravity is at 1 - 1/4 inch from the leading edge and you really need to pay attention to this as this model is very sensitive to incorrect C-of-G setups.

This is my first flight of any GEE BEE and read all the reviews as to what for setups, take-offs and landings and memorized with my brain and thumbs! Early this morning I touched UP the model with my Models Acrylic GUARDS RED to those areas that experienced less than perfect landings. It cleaned up very well with this paint.

Took off slowly as per reviews and increased power slowly as well and it tracked very well with little or no rudder correction. It came up on the mains quickly and allowed a sufficient roll-out and carefully pulled back on the UP elevator and it took off without any issues. Once airborne, it performed like it was on rails! Hammer heads, Cuban-8's, and it maintained some Knife Edge flight as well. Inverted flight was natural for this model.
Need to keep it with the 3-Cell, 1800's packs as the 2200's are just too heavy for this model. The 1800's allow for gentle (kiss the ground) landings so, it is a keeper!

I could not believe my eyes when I visited an old friend who was leaving out of the state after living here in Orlando, Florida for 30+ years.

I came to his house at Waterford Lakes because he was selling a few models and I did purchase them. After placing all of them in my car he tells me that I had forgot one and I looked puzzled and said what, when, how?

He brought me back to his garage and handed me a familiar box and one that he said I gave him about 19 years ago and just could not believe it.
The model is one GWS FORMOSA (original) that I indeed gave him long ago and I opened the box and finally recognized the pre-assembly work (my work)!

Well, I now have it again after being stored for 19 years!

I am getting her done! Soon!


I may bring back my Snow Cone! 🙂

Flight Summary Report - Durafly Ugly Stick V2:

Holy Cow!

By switching to the inexpensive Park Zone 15 motor (950Kv) transformed this model into a more capable and spirited Sport Model like an Ugly Stick Should.
The up-lines were just amazing and with much more power and airspeed and pretty much all other maneuvers were an improvement like Night to Day!

The model was flown nothing over 1/2 throttle using the APC 10 X 10-E propeller and GEN ACES 3-Cell, 2200mAH, 35C, Lithium Polymer packs.
The best of all is the Park Zone 15 and extended forward motor mount provides an additional Nose weight component and provided the Center-Of-Gravity Spot ON!
Brought a grand total of six (6) RC Airplane Models to the RC Club and wow! It was the best weather conditions one could dream of.🙂

I was lucky that a former RC Club member sold me his Durafly Ugly Stick V2 on Friday afternoon.

On Saturday I flew it completely STOCK and was not impressed on several aspects of it's flight. I didn't have any issues with the battery compartment nor the Center-Of-Gravity as I am using the GEN ACES 3-Cell, 2200mAH, 35C, Lithium Polymer packs with a ESC cable converter since I have all my batteries with the T-Connector (Ultra Deans) and even so, it is still doable in carefully situating the battery in that compartment with no issues.

The up lines were not as fast or powerful as I wanted for such a light model. The STOCK power system is adequate but, didn't have that gusto that I was expecting from an Ugly Stick of this size and weight. It performed all the Hammer Heads, Cuban-8's, inverted flight, etc.. however, just something was missing with the Airspeed. The stock propeller is a wooden (no name brand) 10 X 6 and it is my thoughts that it should be at least a 7-pitch.

I found a brand new Park Zone 15 (Black metal case) that you find in many Park Zone and of course E-Flite foam models and went to work a few minutes ago and was successful in drilling new holes on the White Plastic motor (Park Zone) mount to match the firewall of the model. I selected the APC 10 X 10-E propeller and the Watt Meter showed (Static Test) of 22.4 AMPS wide open throttle on a fresh fully changed battery pack. Okay the observed under load Voltage was 11.8 Volts and 22.4 AMPs thereby, 264 Watts!

Therefore, no need to change out the STOCK ESC from Hobby King as the STOCK ESC allows up to 4-Cells. For now, I am keeping it 3-Cells and my thoughts are that it will ZOOM with ZEST appeal at 1/2 Throttle now that I have lots of Pitch Speed and current draw is way below the maximum limits of the STOCK ESC.

My goals here is to WAKE-UP this model with a little more ZIP and ZAZ so, I can really enjoy it like an UGLY STICK should.

More to come in the morning!

Greetings good people!

I normally don't post any issues here with Shipping of items from RC Vendors but, this one I need to share and make sure you all have an acknowledgement of what is going on with FREE or very inexpensive shipping via USPS and those RC Vendors who use Priority Mail from USPS.

EDIT: I am not in the least blaming Garret from Altitude Hobbies for this as he and I are not in control over the rather bizarre COVID-19 situations and USPS places a RED bar on top of any Tracking Page explaining this. The even more strange thing was today I received another package all the way from ROWLETT, TEXAS and it originated there (Shipped) on Feb 1st and arrived today Feb 3rd and it was USPS Parcel Select Ground! It does NOT make any sense!

My package from Altitude Hobbies has arrived in my Seminole-Orlando Distribution (Priority Mail) and departed this Distribution Center on 21st of January. Of which it still has not arrived at my "Local" Post Office Hub since today, February 3rd. The Distribution Center is less than 20 miles away and I can't get anyone at USPS to give me a reason for this delay.

It just SUCKS!

Worse is the vendor who I purchased these items saying that this is NORMAL based on Priority Mail!

Check out my latest e-mail to this vendor!

Now, please realize that my GWS pico Tiger Moth is pushing over 15 years old. The model experienced a Left Top section wing departure in Mid-Flight this pass Sunday at my alternate flying site.

The model was just commanded to a routine and 1/2 throttle loop and it is when the wing section departed from the model. The Tiger Moth continued to fly without any issues and landed with a kiss-the-ground manner.

Repairs have been completed and re-enforcement of the Wing -to- Strut attach points completed as well. (Additional pictures can be seen if you select the Blog!)

Flying wires were re-adjusted to keep the top wings from flexing and yes, a reduction of dihedral was the result, however, the under camber wing will keep the model with stable flight using just Elevator & Rudder....Continue Reading

The mishap report starts here:

Took a careful look and the old Original Gorilla Glue (Brownish Residue) was carefully cut out from the underside of the wing where it attaches to the outward wing strut and now using the newer Gorilla "CLEAR" glue that does NOT leave any residue nor expands, it will be a much better repair.

I have been using the Gorilla "CLEAR" glue for a little over a year now and it has the best results in many repairs, especially for foam airframe models and even my larger Balsa & Light Plywood models.

I am now cutting some Depron Foam strips to later re-enforce the attachment points underneath the wing where the outward wing strut attaches to the foam wing to provide more additional surface area and strengthen the attachment point.

More pictures!

My Moth is the Original kit form with the thin wings and my bubby (a few pages back) is the 2nd generation pico Moth with the thicker wings. My pico Moth had a wing departure yesterday (01-30-2021) morning with its top Left Wing and it was about 85 feet high and this occurred right after I commanded a loop at 1/2 Throttle. The wind was picking up and I should have know better.

This break is not new on my model as many many years ago it fell off my car due to windy conditions and this same wing piece broke off and I had though I repaired it well. It seems like (if you examine the pictures carefully) that this is a structure failure due to gusty winds and going beyond the airframe capabilities, not withstanding my Himax HC2212-1180 power system on 2-cells, 800mAH, Lithium Polymers.

Why? Because the Himax HC2212-1180 is exactly the same weight as the STOCK IPS Brushed - Geared power system.

My buddies pico Moth being the 2nd generation would have withstood this loop as it has the thicker wings and landing wires as that of mine.

Okay the pictures after "landing" like a baby doll. This pico Moth is a TIGER! It just maintained it's flight after the Loop maneuver like nothing happened!...Continue Reading

Much better Video with BLUE skys late afternoon Friday, January 29th, 2021!

Also, like the Title indicates, this model does NOT have any SAFE nor AS3X. It is not only that I don't need these fantastic programmable software assists but, the complexity it adds to someone new and as one of five (5) instructors in my RC Club, I don't train anyone with those receivers that employ SAFE, AS3X. Instead, I give them traditional instructions on how to familiarize themselves with their Radio Gear and setting up their model without any Receiver that employs SAFE or AS3X. I have seen many that get trained with these software programmable receivers only to crash their shinny new Warbird (ARF) later because it didn't have a Receiver that employs these assist devices.

My specific Apprentice in these Videos that I shared is being commanded by a standard Spektrum DMS-X Receiver and it's the AR400 Receiver with the amplified in-line antenna.

My thoughts "is" that if you are training to fly there is really no substitute for person-to-person instruction with the basics and note that this model is Tricycle gear and many do not learn the effectiveness of the Rudder another reason they crash their first Tail Dragger such as a heavier Warbird.

Okay, in this new Video (01-29-2021) the model performed excellent Sport maneuvers such as Cuban-8, Knife Edge, Hammer Heads and continuous axial rolls.

Amazing model, never thought it could.....
