NGH 60 Inline Twin 4 stroke Petrol Engine

I’ve been testing one of these new offerings from NGH on my test stand in anticipation of using it to displace the DLE 55 currently occupying the nose of my ESM P40. No issues with the DLE is continues to give sterling service but the sound of the 4 stroke twin holds an irresistible attraction!

In any case, being a new kid on the block, I though my experience and observations might be of assistance and/or interest to those of you considering this engine. At this stage it’s had about 2 hrs running on the test stand. I’m running 91 octane gasoline mixed with a good quality semi-synthetic air cooled 2 stroke oil mixed at 25:1. The prop is a 2 blade AeroStar 22x10.

General Appearance: The motor appears well made and the finish is comparable with any quality engine on the market. NGH seem to be using the 30cc single head and cylinder as the basis for the twin although I suspect that the twin has a lower compression ratio as the compression is noticeably lower than that of the 30cc single that I have. This has the advantage that a starter will readily fire the twin up whereas it can struggle to spin the 30cc single!
Starting: The engine needs some throttle and choke from cold. It needs to warm up so the choke should be gradually released until it will hold the throttle setting then the engine warmed up. Once warm up is achieved, it should settle to a reliable idle. If the engine has been stopped for 2 minutes or more it needs...Continue Reading

A scooter ran a red light at 25mph & smashed straight into it. Miraculously, only the wheel was smashed. He broadsided it & dragged it a few feet, but manely took out the food it was carrying. Scooters & bikes are in the grey area of not having red light rules enforced & not having speed limits.

In regular use, the lion kingdom has had 1 wreck every 2 years & all in crosswalks or sidewalks. The 1st wreck was an SUV turning right, destroying the cargo area, damaging the chassis & 1 wheel.

Ground vehicles which coexist in the road network have similar expenses as flying, but instead of impacts with the ground, it's impacts with full sized vehicles. Fortunately, they don't damage the other vehicles or cause injuries, but when cars impact robots, car insurance doesn't cover it & it's pretty much the robot owner's expense.

They're quick with the sorry's & the excuses but no driver is willing to pay for it. Lions don't pressure anyone for money because of what happened to quad copters. If there's any hint of liability, they'll regulate the ground robots into the stone ages. They're already banned in almost as many areas as quad copters.

The mane problem is they're harder to see than humans. Near misses with cars happen every month, usually when cars make right turns. High acceleration & planning for it is key. The lion kingdom usually has the robot drive ahead, in order to bait cars. If the car keeps going, there's a good chance they don't see the lion.

There were a few right turns that would have impacted lion instead of robot. The robots are all intended to be expendable, but there's still a desire to prevent one from becoming a total $500 loss, in today's money.

I was inspired by the X-31 thrust paddles. They looked simple and effective. My goal is to make an EDF that truly capable of hovering like the turbines. The model will be the Freewing Mirage. It'a AUW is reported to be 2,200g. I'm installing the Schubeler 80mm fan set up for 6S. With 4,000g of thrust I just might make my goal. I'm going to make a test setup t dial this unit in. Shouldn't be too difficult to program with my 18MZ. It will use 4, 7g servos with 27 oz/in of torque each. I'm shooting for a complete system weight of 65.3g. I may remove the rudder servo as it will not be needed. The TV will work as well or better than the rudder and it will work at zero airspeed.

According to US media reports, on October 15, a young boy named Essen and a pet dog were lost near the town of Pamo, Minnesota, USA. A total of 600 volunteers participated in the search and rescue, and the local police also dispatched patrol helicopters. Searching, many people who are concerned about the event prayed for the boy online.

The search and rescue work continued from 4 pm to late night. Due to the lack of additional lighting on the farm night, the visibility was extremely poor and the outdoor temperature dropped drastically, which brought great difficulties to the search and rescue work. I thought that Steve, a volunteer from the drone service company, brought his drone, a multi-functional drone developed by an industrial drone manufacturer in China, equipped with a thermal imaging lens. It can continue to work at night.

It is understood that the thermal imaging camera used by Steve integrates a high-precision thermal imaging sensor and a 4K visible light sensor. It can record and transmit thermal imaging and visible light effects at the same time. In real-time image transmission, thermal imaging and visible image can be displayed side by side or picture-in-picture according to the needs. At the same time, the latest machine intelligence technology is combined with FLIR MSX image enhancement technology. The combination of visible light and thermal imaging provides rich detail and produces sharper thermal imaging, making it easier for users to identify targets. At two o'clock in the morning, when searching for a cornfield about a mile from the farm, two spots appeared in the thermal image, and a long spot was moving in place. "I think it should be a pet dog." And the boy, so I informed everyone," Steve said. Search and rescue personnel immediately went to the location to successfully find Ethan and his pet dog.

After being rescued, the boy had all the good signs and had returned home after being examined by the hospital.

This is what I managed in our recent Western province and South African masters championships. I flew in the Advanced class and when our new season starts in January I'll be flying in the Masters class. (one level below F3A). I competed with my Mythos 125e. On the Saturday we could only fly two rounds because of the strong winds (35 kilometers per hour) after which I was lying in first position. 👍 😁

I found this old radio controller but i don't have the fitting receiver... but it is nevertheless possible to use the onboard chips to use it with an arduino receiver or do i have to build an transmitter one myself with the accelerators from the control..?

The lion kingdom can remember no time when it needed 2 power supplies simultaneously. They were only used for remembering different settings or having different connectors. Manely, they were hoping for a future need that never came.


A Rudung was sacrificed. The new butter surprise created a stable 9V from a 12V battery. It had a 0.5V dropout.

Subjectively, the results were more realistic than without a regulated voltage. There was a steep drop in PWM for the 1st turns, then a leveling off. Finer precision was still a matter of complete drives & measuring charge.

The alignment affected downhill drives more than uphill. It might have been because more weight was on the front wheels when going downhill.


The 1st 9.2 mile drive burned 246mAh/mile.

Yesterday the San Antonio Prop Busters held our 4th Annual event for modeler built models. Our thought was that by encouraging modeling we would get people deeper into the hobby. For a small club, I think we’ve been pretty successful. This year we had great weather and 17 registered pilots, who averaged two planes apiece. In the pictures below you’ll get a taste of the variety. It wasn’t like the typical fly-in where you see same, or similar, factory built planes, one after the other.

The event is now dedicated to the memory of the master modeler Lee Moore. A mainstay of the early days of a Bomber Field and similar events, Lee spent a good portion of his last years flying with us and inspiring us. One of the delights of our club meetings was when Lee would show up with his latest creation. He was super supportive of this event and helped several members get over the hump of their first builds to be able to participate.

We thank our friends with the Tri-City Fliers who stepped up and helped us out when we lost our field (as reported previously in this blog). They have a beautiful site about 50 mi East of San Antonio co-located with a vintage aircraft museum. This distance may have cost some attendance but I als noted that Oct 19th was a very busy day in Texas for sanctioned events.

A special thanks to Jim Rice, Former AMA Dist VIII VP and recently retired chair of the AMA safety committee. He was responsible for a number of the excellent prizes we were able to...Continue Reading

I know that many have old GWS Slow Stick Models that have been stored perhaps as long as mine and it takes just a few minutes to test and test the electronics and Radio Gear to make sure ALL Systems work flawlessly.

In my case with this RED GWS Slow Stick, I found today that the No-Name Brand 20-AMP ESC had a hole in the Heat Shrink Material right over the FETs and also during testing by connecting a Battery and Transmitter it just did not want to come alive! This particular Slow Stick is on a BERG super narrow band 72-Mhz (Castle Creations Product) and coupled with my JR XP-7202 Synth Transmitter that is just Rock Solid. Well, after several connects and disconnects with the Battery -to- ESC connector I found a strange issue with it being completely active and then, it went dead after a few minutes handling the connector!

I took off the Tape for the Positive and Negative at the ESC Connector (once I had everything disconnected from the Battery) and found a very bad SOLDER Joint at the Negative post. Needless to say, I just went ahead and replaced this ESC with the Bullet Proof E-Flite 25-AMP ESC and like magic the model stayed active without any issue nor brown outs. This exercise made me create a new Memory Location for this Slow Stick and on Channel 31 so, not all was lost and it has it's own memory location on the Transmitter!

Additionally, I checked all linkages and foam hinges and they all passed with flying colors!
