A1405 motor from GearBest (0 min 56 sec)


So we know that peak current was 3.15A / 25 watts with all props tried , 5x3 - 5x4 - 6x3

So this tells us that none of those props really loaded up the motor , also tells us the 3000kv claim is just a claim .
I put the motor to the Tacho ..

4.5x3 = just over 11,000 RPM > Oh dear !
6x3 = just over 10,000 RPM

My guess would be that this might be a 1200 - 1400kv motor , ? ( 1400 at best ) ..
I could be tempted to try a 7x3 if I could find one physically light enough , because this is a very small motor or maybe a 5x5 ...

…continued

Now that the gimbals were far enough apart to get full range from the sticks, I was looking to get some use out of the nine available buttons and switches on the transmitter. First, I needed to completely remove the "F" switch from the face of the transmitter to prevent my pinky finger from contacting it while I was moving the stick. Simple enough, a bolt with a flush mount head was placed into the vacant hole left by the "F" switch.

Next would be finding a sip-and-puff mobility-switch with more than just an "on and off" or "open and closed" two position function. I found a suitable switch at Broadenedhorizons.com that has what is called a "latching" feature that would allow me to use two separate switches simultaneously on my transmitter. My cousin stripped the transmitter apart once again and made some custom modifications that included adding 3.5 mm jacks to the outside of the case that would allow me to plug in my new mobility-switch. He wired the stereo jacks in line with the current "I" switch so that the black pushbutton on the Spektrum transmitter would still function with or without the mobility switch plugged in.

The Broadened Horizons mobility-switch is pretty simple in concept. "Puff" into the tubing and it momentarily closes a switch. "Sip" on the tubing and a small internal ratchet switches between two positions.

The toggle for the "F" switch was...Continue Reading

Well those 1.5mm screws showed up today .. ( I thought I had a 6A ESC ? - Must have misplaced it )
Anyhow .. I have a 12A ESC I can test with .

Motor is 1s - 2s so we will be using a 2s Battery ..

GB gives no specs on the motor ..
HK has a motor !

A1405
30 Watts
6A
3000kv

So using a 2s battery and ...

5x3 - 5x4 - 6x3 and a cut down 5x3 to 4.5x3 .

First I tested current draw and Watts , every prop was around 3.15Amp and 25 Watts and the motor ran cool . So obviously I am not maxing out the motor at all . Then for kicks I gout out some cheap electronic scales and I tested for thrust . Motor is mounted to a wood block , I am setting the motor up for pusher ( push down ) to see how much weight the scales register . Obviously with the motor off one sets the scales to zero ...

5x3 prop gave around 110 grams of thrust .. 5x4 prop was about 115 grams and the 6x3 was around 120 grams , but obviously this is static thrust . Pitch would have something to say about flight performance , so I will go with the 5x4 ...

Well with about 3A current draw , around 110 grams of thrust .. I think the motor will fly my wing , especially if I can make it 100 grams RTF ..

Not sure the GB motor can live up the the HK motor specs , just does not feel like a 3000kv motor .. Its dark and tomorrow I will tack the motor with the 4.5x3 prop as it did rev out a little more on the little spinner .

I have been gone for so long I forgot about being a member here. I am so horrible at focusing on all of my different hobbies. I have serious HAD (hobby attention deficit). I sort of lost sight of aircraft and got into model railroads. Then I got into making terrain for tabletop games. Recently I was telling an engineer that I work with about the EDF tri-copter I built. I was bummed out I didn’t have any pictures of it. Then I remembered that I had posted some on the internet somewhere. I searched for the Twins Multi Purpose Cargo Plane, and found my way right back here. Hoping to get back into the hobby.

4 months after the last wheel failure, the same left front wheel broke off again.

https://www.rcgroups.com/forums/show...e#post38834656

& the right front tire continued to have wear problems. At least it got a good video before it died.

My wing is here from FastTech dot com ...
I put it on the scales and got 46 grams ( for the foam components ) , that leaves me some 54 grams to play with to get to my goal of 100 grams RTF
Just waiting on the 2.5g servos now and some small ( 1.5mm ) screws

Review of Eachine E010S PRO - 65mm 5.8G 40CH 800TVL Camera F3 Built-in OSD High Hold Mode RC Drone Quadcopter


This quad remained my on the Jaws. Too bad it cant go underwater



This cool design aldought brings great benefit for beginners because all electronic parts are well protected in canopy it makes life a little bit complicated (we are spoiled) to initially setup the quad because bind button for RX, CH/TX button and USB port are all hidden under canopy.
Good thing is that after initial setup there's no need to do that again because quad has OSD so most important BetaFlight settings are tunable via OSD.

I can reccomend this quad already to beginers because its great protection of el. components and antennas.




VTX antenna is hidden in shark tail ant RX antenna is laid horizontal "out of the box". When I opened the shark to adjust my CH/TX I put the RX antenna to upright. I believe it should be better that way.

I did a short hover and LOS test after setting in BF my modes and it flies great.

I was involved in the power selection for the HK Avios Grand Tundra when Stuart Warne was still at the helm. Now that Stephen Neill has taken over he graciously sent me one for my personal use after I beat up a prototype model Stuart sent me last year. The proto is still in good flying shape, but kinda dented and dinged. Originally just an "albino", Stephen sent me a set of decals for it. I also converted it to clear windows which I will show how that is done after the pre-orders have reached the modelers. but until then I would like to discuss the inflight data I will be collecting on the model.
