Near the end of the war, the army was after a new observation/liaison/ambulance airplane. Piper took on the challenge by highly modifying their J-5. Starting with the wings, they added full length leading edge slots and long flaps that extended to 60 degrees. In the fuselage they added a large greenhouse with windows running the majority of the way down the fuselage and a large upward folding hatch to store a litter for patients. In the landing gear department they added an extended gear leg and ditched the bungees in favor of a large shock strut going all the way up to the upper longeron allowing for 12 inches of travel. Lastly they added a custom built Lycoming O-290-1 of 130hp with a Sensenich wood prop. Piper was granted a Type Certificate in July of 1945 for the “Piper L-14 Army Cruiser” and they subsequently produced five new airplanes and completed the two prototypes to production standards. These seven airplanes were presented to the Army for testing and evaluation. With the requirements satisfied, the Army ordered 850 airplanes. Lycoming delivered their order of 850 engines and production of the airplanes commenced in August of 1945 however it was immediately halted when the army canceled the order. The only part of the contract completed was 9 fuselages. When the war ended, Piper was given back their seven completed airplanes and they finished the nine fuselages they had built in a “civilianized version”. All 14 of the completed airplanes were sold off, many of them to overseas or South American buyers. Today only two remain in flying condition with a third project floating around Argentina.

The Early Days at Ryan:
In the 1930s, San Diego was home to a hub of aviation development. In 1927 Charles Lindbergh flew across the Atlantic in a Ryan NYP that was designed, built and test flown in San Diego where Ryan was based. Ryan had become a household name in aviation thanks to the fame of this flight. With their sales taking off, Ryan continued to develop more and more advanced aircraft. Just after Lindbergh's famous flight Ryan took aim at the commercial market with several variations of the Ryan Brougham, a 5 place commercial airplane developed from the M-1 and NYP. With the sales success from the 212 expensive Broughams produced spurring them on, Ryan next took aim at the sport flying and training market. In 1934 and 1935 Ryan began producing the 2 seat ST series. Powered by an inline four cylinder Menasco the Ryan ST-A was a sleek design with tandem seating and controls for two. With a Ryan ST-A winning the 1936 nation aerobatic championship at the hands of Tex Rankin, the airplane grew quickly in popularity.

A Grand Plan:
In 1937 the Great Depression had ended and people were finally spending money again. However, with the price of the ST-A set at $4500 (north of $82,000 in todays money) it was certainly not what most people would call an attainable sport flyer for the average person. Enter Claude Flagg and his associates. A group of 11 engineers and mechanics who worked for the local companies Ryan and Consolidated, both based at Lidbergh field in San Diego,...Continue Reading

Took me longer than expected to finish my Protos 380. I got all the parts in a week or so ago but wasn't able to do any adjusting due to the Vbar USB Port Location and the small size of the 380 frame. I ended up having to cut off the plastic housing of the USB chord to get it to fit. The rest of the build went fairly smooth and the Hawk-RC Blade grips added a nice touch to the head giving it a more "premium" look compared to the stock plastic blade grips.

The only gripe I have with the kit is the tail. Even with the upgraded metal casing and slider, there isn't a lot of room for error and I had to play with tolerances and bolt torque to be able to get the slider moving freely without any binding. There is a lot of mechanical gain on this tail just by design, so make sure to use a servo horn/wheel that has holes as close to the spline as possible and set your gyro gain low. It took me 10-15 flights of tuning in the vbar system to get this heli flying somewhat smooth at 2500-2800RPM. Anything above that and I get a violent tail wag. I attempted to work it out but stopped trying due to how perfect this little heli fly's at 25-2800RPM, you really don't need to go any higher.

The flight performance of these 380's is beyond what I was expecting coming from .50 sized machines 6 years ago. The Heli feels just as "locked in" as larger machines and is very stable. The drivetrain is obnoxiously quiet thanks to the belt-driven transmission and tapered profile on the AzurePower Blades. Not bad for a $200 kit - I really can't see justifying spending more on other 380 sized helis.

I’m having trouble with my Bezgar 1. When I turn it on it goes on reverse on its on. Then when I set the throttle going forward it works fine and steers fine. But when I try to reverse it won’t go. Anyone know what will be the problem. Thank you in advance

Why I haven't been active on RCG threads in a few days....

Uhhhh!!!! I got distracted...


Blame it on Covid-19...

First of all as some are aware of just coming out of a Covid 19 situation here, and praise the Lord, everybody came through with out any harm. (Incl. Me )

But since I was on quarantine my mind started to wander, and then fixed on the stupidest thing/idea... Saw this piece of foam packing and it was all downhill from there.

Anyway the entertaining part first, and then more details if anyone is interested, sure as heck not gonna waste a lot of time putting together something if I'm the only one looking at it, but then again I have a very low "outside" interest level, so leave a comment, I can't say no to sharing info if someone asks.

This morning I awoke to 6 inches of snow, 20 degrees and a forecast 15 mph winds ....
Oh Yea - Another chance to slope ,this was the third time I was able to get out on the hill this week
Once again at the top I found more wind , a steady 20 gusting over 30 mph to shake the rust off my trusty KA-8 .
I kept her up for around 20 minutes,the gusts were definitely flexing the wings
I popped the spoilers and walked her in during a lull in the gusts , no need to beat up an old favorite too bad.
Next up was the LEG ODR ,after some trimming {not sure why it was out of trim but its been a while since I last flew her } I was zooming back and forth close to the hill face {Kansas on my mind }
The wind kept vectoring west to north west then back west sometimes just a few degree's sometimes more - it kept it interesting
After about 45 minutes of fun my fingers were getting cold so I decided to head back down to the car.
A good week of flying {and climbing } has my legs and lungs ready for some rest and football tomorrow - GO BILLS !!

In 1928 Boeing was working on what would be the last generation of high performance military biplanes before the wave of monoplanes took over. Boeing’s entry into the fighter biplane market was the P-12 series. Built for both the Army Air Core and the Navy, there were many versions of the P-12 through its development. With Boeing trying to keep up with the monoplane phase, they modified one particular model of the P-12, the F4B-1 (last picture) to be a monoplane. Enter the Boeing XF5B-1 or XP-15. Finished in early 1930, the first airplane, (the XP-15) was essentially an XF4B-1 with the bottom wing knocked off, a new landing gear and modified ailerons. It was found to be unstable due to the vertical surface of the tail being too small. With an enlarged vertical surface, the XP-15 was presented to the US Army for testing. With a top speed of 190mph, it was no slouch in the speed department, but it was found to have a poor climb rate and a high landing speed so it was never purchased. A second airplane was completed, the XF5B-1, for presentation to the Navy and was ultimately purchased but a contract for more was never reached.

Powered by a 525hp Pratt & Whitney R-1340 and hauling the mail at 190mph, without even mentioning it’s fantastic looks, the XP-15 might have been the ultimate parasol.

Made this one as thin as possible, taking out all the artwork & using .8mm thick panels. Thickness is only limited by the switch size. Took out the temporary screws, which was a disaster. They need the temporary screws, even when the sticks appear to stay in place without them. An attempt at knurled areas was subjectively successful, if only because they created a widened part. A better solution might be hot glue or removable TPU caps. The button caps need more clearance. Lions tend to hit the power button when they go for the speed buttons, so that might have to be moved up or get some shrouds.

Got rid of the bulge, yet the extra length required is barely longer than a lion paw itself. It should be reprinted with the temporary screws before committing to soldering.

UMX TT signal loss (5 min 22 sec)


Re routing the antenna helped some ! But not enough !

So I have punched more holes in the TT and this time routed the antenna out the bottom of the fuse , maybe 1mm .

Range checking was good , at least double what I got before .

Butt ! @nd its a huge Bee Hive ! This antenna definitely seem to have a dead zone .. And that appears to be when it is directly pointed at the Tx .
Thats why I have it sticking vertically down .. Which does not eliminate the possibility of the dead zone ..

Last time , the prop did come lose ! Hence the funny sounding motor run .
That small cheap nasty self tapping screw seems to have stripped out the prop shaft .
So I had to replace it with a hex head screw . More butchery of the foam spinner , required .

Do I have to mod the antenna ?

Kiwi_Craig RC is setting up a blade 450 with both the new Micro Heli "pro" tail assembly and the new 3 blade DFC main rotor head. The Microheli team have been testing the heck out of these for the last few months fine tuning the geometric setups for the Pro tail and the 3 blade DFC head units. The parts have been provided to me to cary out a technical evaluation and independent test flying and I thank the Microheli team for this opportunity.

Checkout the new 3 blade head on the Microheli web page.

https://www.microheli.com/helicopter...330x-330s.html

Personally I really like 3 bladed head units and have done a number of custom builds on micros (K120, blade 130S, WL V950, blade 200 srx with both RKH short blade and Microheli 3 blade with my own long blade setup and upgrade motors as well as the factory Oxy 3 cubed and actively flying the 230S three blade unit on my upgraded AS355 scale bird also with 300x power. I also have Gaui X3 that's scheduled for the X3L - 3 blade conversion and tail stretch and 3 blade setup to go into my Tarot 450. So when Microheli advised they had a 3 blade DFC setup coming for the 450/330 this was a must have addition for me.

Microheli have provided me with a unit for technical evaluation and test flying and I thank them for the opportunity to review this product. I'll document the assembly (all very straight forward) and any FBL tuning - changes needed on the AR7200 beastX unit followed by flight test and reporting on my findings.

Enjoy the product photos whilst I get the unit assembled and then get the FBL settings checked over.

Microheli also have a full complement of spare parts amiable in support of this product with details now up on the Microheli website.

After initial unpacking and inspection I can advise the fit and finish on this product is totally stunning, the machining precision and finishing is superb ! I'm working through the various engineering details and will be reporting further on the design aspect of the assembly.

Hey,
I had a lot of issues to get my ESC and motor running. After contacting the manufacturer of the ESC (Flier) I knew which firmware to flash (Boat_UV30 if you wondered). Now my motor is running but acting weirdly on low rpm.

Please see the video I linked.

bldc Motor rough start issue (0 min 36 sec)


Since it is a sensorless motor, it's obvious that the start won't be smooth. But I don't think it's supposed to be as rough as it is with mine!
I tried resoldering all joints, changing the motor timing, changing the motor speeds and more. I'm out of answers and couldn't find any other people having similar issues. Also I don't know how else to describe this issue than saying it's a "rough start".

I'm happy for every tip you can provide!

Hello good people!

Now I am not recommending anyone to do this with any of your models, especially if they are Electric Power. My situation is a little different because this Trojan model has crashed now several times and I had the opportunity to provide good protection to the ESC against moisture since I live in a very humid and swampy environment.

This weekend, most of Central Florida is Socked in with low Drizzle rain Clouds with DEAD CALM conditions that makes it all so tempting!

Okay, here's my Video of my 10+ year old Park Zone (now E-Flite) T-28 NAVY Trojan 1.1m (44-Inch wing span) with STOCK Power System and swinging the XOAR wood 2-Blade Glow 10 X 7 Propeller and 3-Cells, 2200mAH, 35C Lithium Polymer battery packs. This model has custom retracts.

It zooms with zest appeal.

This is the first video in a series to help new pilots enter into the radio control (RC) hobby. A beginner's RC helicopter was used in this tutorial, as the method of control is the same for both drones and helicopters. The helicopter's advantage over a drone for beginners is that it is a much more efficient flier, and allows longer practice flight time per battery charge. The tutorial helicopter that was used can achieve up to 15 minutes of flight time, and may be found here .

This series will focus on basic piloting skills for flying drones and helicopters. We'll start with a discussion of transmitter flight controls, and how they are applied to fly the aircraft in hover. In follow-on videos we'll examine yaw, horizontal translational flight, turning, and orientation tips.

Yep Les Amis,
4 oreilles valent mieux que deux ! J'ai en test dans cette vidéo les deux derniers produits de la marque Tronsmart. Le casque APOLLO Q10 bluetooth et la petite enceinte nomade FORCE 2. Ces deux nouvelles sorties de la marque sont encore une fois d'un très bon rapport qualité prix. Le rendu et la puissance de la FORCE 2 est bien présent et apporte l'étanchéité totale par rapport à la T6 Plus. Le casque lui, très confortable et léger, est d'une autonomie surprenante et la réduction de bruit très impressionnante . En bref, un investissement très raisonnable pour les petits budgets qui veulent se faire plaisir ! ... Bon Film et merci à tous pour votre soutien .
