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....Continue Reading

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.

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 available 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.

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 .

Follow me here, keep in touch through it. I just threw something together, raw as it is to have my spot to light upon for just personal page and contact information. I just have had enough of being under the yolk of some self proclaimed authorities. I am big along helping people getting their own space too. We should all have our own domain to just do our thing, express ourselves and not have to conform to some outsiders system, controls and rules.

There will be of course, build logs as I've been doing here and more, but that's only part of who and what I am about. I am doing my own thing there regardless in that world and more from now on.

Micro Heli Pro Tail assembly for the Blade 450 X / 330 X / 330 S / 270 CFX / Fusion 270

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.

Starting off with the new "PRO" tail assembly, all I can can say is WOW, WOW and WOW, is a truely superbly made piece of gear, totally new design that does away with the forked clevis - bell crank and circular pitch slider "wheel" which is quite prone to wear and then results in mechanical slop. Similarly the blades plastic tail grips are prone to stretching and become floppy with laterally movement occurring. Combine the two and you get a standard tail assembly that is hard to keep working well as the flight hours roll up.

These clevis - bell crank type tails can be made to work exceptionally well, just look at the Gaui X3 and Oxy 2/3/4 helis. Microheli also does an upgrade for the various plastic parts in the standard assembly as well.

In designing the ultimate tail unit Microheli have adopted a sliding block unit with a double jointed pivoting arm, this gets rid of the sliding clevis pins and pitch slider...Continue Reading

Watching this video got lions thinking about pendulum robots again.

Can A Self Balancing Vehicle Drive on a High Wire? (6 min 30 sec)

The problem is gyro stabilized robots have to be perfectly balanced or their gyro quickly saturates. They either need automatic weight shift or a way to precess. Pendulum robots accelerate in the direction of their center of gravity to stay upright. If they stay unbalanced, they'll keep accelerating until they run out of power & fall over.

The problem is pendulum robots are slow because they have to accelerate a lot of mass. When they move, they're either slowing a lot of mass down or speeding a lot of mass up to keep their CG centered, but never moving at a constant speed. Lions once considered fastening a quad copter to a pendulum robot to stabilize it. It would burn a lot of power, make a lot of noise, & take a lot of space. What about attaching a moment gyro to a pendulum robot to absorb the short term inertia, allowing it to travel much faster?

Moment gyros have been fastened to stationary pendulums but never to make a pendulum go real fast. This is a good example of the kind of system which could make an inverted pendulum go fast. Maybe a moment gyro could be used to make a legged robot cheaper & faster.

UMX Turbo Timber with Rudder Mix (5 min 3 sec)

I mixed in some rudder in stability mode to tighten the turns ..
From memory the mix is for 20% rudder added to the ailerons , and it really helps in tightening the turns .
I was thinking that the TT would be a nice tight space flier but in stability mode it's a little lazy with just bank and yank !
So mixing in a little rudder really helps kick the tail over . And with the TT having such excellent slow speed handling , kicking the tail does not hurt .
After a little over 4 minutes flight time , I had 53% battery when I came home .

The vertical performance is not brilliant and then again it's not terrible , maybe a little ho hum !
I will have to see about a 2 blade replacement prop .

Signal Warnings - I lowered the warning point / signal strength .. No joy there !

So today I came home and punched some holes in the side of the fuse and pulled the antenna thru !
Then tapped it to the outside of the fuse , just a bit of tail sticking out . ( pictured )
Tripled my range check . That's got to be nice
