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 ?

Team, no doubt you have seen 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 bald and Microheli Long blade 3 blade heads and upgrade motors0 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 of the X3L - 3 blade conversion and tail stretch and 3 blade setup to go into my Tarot 450. So when Microheli advised they has 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. I'll document the assembly (all very straight forward) and any FBL tuning - changes needed on the AR7200 beastX unit.

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.

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 !

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 .

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.

Just purchased a Dynaflite Fun Scale 81" Spitfire that seems complete except for plans and the manual. I have downloaded the plans but not the manual
the manual, question is are one or both available for purchase? Also any info as to when these were sold or discontinued would be greatly appreciated.

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

History of the Travel Air:
The History of the Travel Air is intertwined into quite a few of the major names in aviation history. Starting with Laird and Swallow, down the grape vine Travel Air was eventually associated with Curtiss-Wright, Cessna, Beechcraft and Stearman. But of course it couldn't be without an extremely convoluted history that one company could be associated with so many names. It all started in the early 1920s with Laird-Swallow. In the 1920s, barnstorming was in full swing and the market was hungry for more biplanes to rake in the cash with. Swallow was one of the early answers. With a single seat in the rear cockpit and room for two up front, the Swallow was a major step up from the Jennys and Standard J-1s that were surplussed from WWI. However, still having a wooden fuselage, it wasn't as tough or as long living as a barnstormer might want. Two employees of Swallow thought they had the answer to this with a welded steel fuselage. Lloyd Stearman and Walter Beech proposed their welded steel fuselage to the owner of Swallow aircraft to a surprising rejection. This sparked some controversy and ended with Stearman and Beech leaving Swallow to start their own company. Interestingly, this demonstration welded steel fuselage was actually turned into a completed airplane by the Winstead brothers (named the Winstead Special) which is still surviving and flying today. Stearman and Beech decided to start their own company using their welded steel fuselages. They...Continue Reading

----- 5 Duh Checklist -----


Sure, those elevon only
"Delta/Flying Wing Death
Spirals to Impact"
can be avoided.

Since no rudder is available to
help defeat the spin, the only
real solution is ‘Duh, don't stall
in the first place'.

My personal mental 5 Duh
Checklist
for deltas or flying
wings with elevons:

Duh 1. Keep plane at 1/2 throttle
cruise always (may vary slightly for
each power set up.

Duh 2. If climbing/banking (more than
about 30%) add some throttle first.

Duh 3. If totally cutting or reducing
throttle (landing approach) keep
nose below horizon so judged
'airspeed' is always above stall. Use
shallow banking turns, less than
30 degrees.

Duh 4. *** Never cut throttle and
attempt a steep turn from
'downwind leg' or 'base turn'
on landing approach, especially
with a tail wind.

OK, almost there,

Duh 5. Using some power
and with nose pointing
slightly down below the
horizon...aiming point is the
runway threshold...fly the
wing into 'ground effect'
a few feet above runway or
grass before cutting throttle
completely.

*** Note, Duh 4 is the biggest Duh
I usually see at the flying club ...
somebody thinks they are going
too fast on the down wind leg
with a tail wind, and chops
throttle and does a steep
panic 180 turn to land.

Duh, doing a panic 'throttle
chop and steep turn with a
tail wind’ is known as 'flying
your ground speed', not your
actual air speed.


Result is, Duh, stall and spin
to impact at low altitude.

Have fun.

After 28 years, my local HobbyTown USA will be closing towards the end of this month (1/30/21). It was a great place with great memories and a really good on-road racetrack. Rumor has it that NorCal Hobbies is interested in it but not sure if they will keep it a HobbyTown...probably not.

Yesterday I went down there to pick up 2 Traxxas Slash OBA kits and they gave me one of their Tamiya vinyl banners/posters! So I hung it in my garage just now and it sure looks great!!! The Tamiya Hornet was my first hobby grade RC so this made it extra special! Thanks for the memories and banner HobbyTown USA!!!
