I didn't do well in any absolute sense during this race, but it was a personal record for me, better than I expected, and a lot of fun. It doesn't get too much better than that!

There are actually 19 channels being used between the Ocusync Air unit and the Goggles RE, 7 on 2.4mHz and 12 on 5.8mHz. They are as follows: 5731.5mHz,5741.5mHz,5751.5mHz…5841.5mHz 12 channels in total in 10mHz increments and 2407.5mHz,2417.5Mhz…2467.5mHz 7 channels on 2.4mHz 7 channels in total in 10mHz increments. If you want to give the frequency for your channel you will have to choose 5.8 or 2.4 and then the channel number. You cannot do channel shifting between the two. I hope this helps.

iRangeX RM601 receiver test Part 2 1s battery (7 min 21 sec)



Ok , so many hate video ...

This test is with a 1s Lipo ( 1000mAh ) , there is only one 9g servo attached but I am loading it with 201.8 grams ..
RM601 is bound to my Jumper T8SG Plus in DSMx mode ..

Battery off the charger , no brownouts ! , takes the 201.8 grams ok . Lets not forget these 9g servos are not low voltage .

Then I discharged the battery with my hobby charger to a static voltage of 3.99 volts
3.99v , again no brownouts , not even with the servo under load .

Battery discharged to 3.8v , no brownouts .

Battery discharged to 3.71 volts , no brownouts .

Battery discharged to 3.56 volts , @ 3.56v the battery is very close to depleted .. I gave the Rx / servo a rather good work out and no brownouts .

Static voltage : This is the voltage of the battery at rest ( doing nothing - not connected to anything )

Wow , I saw little point going bellow 3.56v as this is pretty much where batteries ( lipo ) are very close to depleted . ( If not depleted ) ..
So I am very impressed ..

Next I jam in more voltage to see if there is any voltage regulation to the servos ( 2s capability )

That will be Part 3
More voltage , a range test , and a conclusion ..

This is an exciting day. Today we start accepting pre-orders for the Beaver kit! Check out the funding campaign on fundable.com:

https://www.fundable.com/moustache-model-works-llc

There are two bonuses for pre-ordering. First, shipping is free! Second, each kit will come with a DHC-2 Beaver ceramic mug from Labusch Skywear. I have 3 of their mugs and they're great.

This pre-order campaign is to raise funds needed for placing the first order. The faster we raise these funds, the faster we can get this puppy on the market. US orders only at this time. Once we've met the goal for this campaign, pre-orders will close for a while, until I can get my website established. We will open up pre-orders again once the shipping date gets closer, but the free shipping and mug incentives will not be available then.

Glue & Fly Series - Interceptor Micro V1 Desert Flight #2



Here is a link to the Video:
https://www.youtube.com/watch?v=fY_wMwwOVOI

Wind is out of the Northeast at 6-9mph.
Flying 20-30ft above the ground it felt like wind of 10-12mph.
Again the wind was not favorable for this Micro Parkjet that only weighs 107.8g, however, I had so much fun flying this on it's Maiden Flight I was right back at the field two days later putting 6 batteries through it ;-)
I filmed 5 of the 6 flights this day.
This is flight 2 of 5

Build, Fly, Crash. Repair, Rinse & Repeat!

Happy Flying!

There are a lot of intelligent, talented and friendly people on RCG. Many have become friends from being acquainted on the forum which adds to the fun of the community. Then as with all public forums it seems, there are the smattering of monkeys with some kind of personality disorder who think it’s acceptable behavior to fling verbal feces at other hobbyists with their negative, hostile and toxic comments.

These are people who many times believe that life has dealt them some kind of bad hand which leads them to be insecure, defensive, bitter and hostile toward others, especially to those who don’t share their negative outlook on life – the ‘poor me’ syndrome. For some it’s the hobby-god complex where they think they know everything and want to make sure everyone else knows that they think they know everything. Some just have a generally toxic personality and could care less about being arrogant and rude or using a brain-to-mouth filter. Those are the worst in my opinion. The impact their comments have on others is of no consequence to them. Not the type of hobbyists normal people want to be around or involved with.

Regardless what stories these people tell themselves, their public behavior can be reprehensible and has no place on RCG or in any other public venue for that matter. They are a disgrace to the RC community.

While I personally appreciate the wealth of information available on RCG and have tried to share my own knowledge from...Continue Reading

Sadly, my Freewing 64mm A-10 edf got shot down earlier this month. I was flying it for the third time that morning and it was flying great. I did an uncharacteristic upside down pass down the runway about 10 feet off the ground when BAM! the right rudder just came unglued but still stayed connected to the servo and it immediately went nose down and made the best foamie crash I've ever had. Foam pieces went flying everywhere! If you have to say goodbye to an old plane, this is how to do it...in a blaze of glory. I will miss it but I'm now into 80mm and bigger edf planes so it will probably initiate an upgrade Don't tell the wife.

To play with I have the iRangeX RM601 7ch Receiver .
Ch1 - Throttle
Ch2 - Aileron
Ch3 - Elevator
Ch4 - Rudder

+ You have pins for PPM and Bind as well Ch5 and Ch6

Now my main goal here was to see how little voltage this receiver would work on and I think I learned a few things along the way ...

A) Current is more important than Voltage ...

I have a variable voltage power supply being used to feed power to the receiver ..
To start testing I fed some 5v @ 0.5Amp to the receiver ..

Receiver was initially set to DSMx and bound to my Jumper T8SG Plus ..
Two 9g servos were attached to the receiver ..

I got so many brown outs it was not funny ...
Tried DSM2 and the brown outs were literally twice as bad ..
I jacked the voltage to 6v and left the current to the Rx @ 0.5A
Yeah , you may have guessed , more brown outs ..

I then pushed the current to 0.9Amp and no more brown outs ... ( Bound back to DSMx )
I dropped the voltage to 5v and no brown outs ..
I dropped the voltage to 4.8v and no brown outs
I dropped the voltage to 4.6v and no brown outs
I dropped the voltage to 4.2v and no brown outs
I dropped the voltage to 4v and no brown outs
I dropped the voltage to 3.9v and no brown outs ( Sorry - did brown out @ 3.9v - 0.9A )
I dropped the voltage to 3.8v and got brown outs ( DSMx )

WOW !
a) 3.8v and the 9g servos were still working ...

So I thought , hmmmmmm , maybe if I crank the current to 1.5A ...

Sunday: The task for today is to fiberglass the wing center joint at the root. This is a pretty critical step for this glider. This is going to with stand all the G's pulled. Unlike some old school kits that I have built in the past, there is no dihedral brace. This is where all the pieces literally come together to create a bond greater than the individual parts. Using Painters tape I taped off the border to prevent epoxy from getting to places I don't want epoxy to be. This kit calls for a 35mm strip of fiberglass (Medium), and a 50mm strip of 3/4 oz glass cloth covering the heavy glass strip. I have never used this method of adhering both glass strips at the same time. I like it, it worked well.

If you haven't guessed by now that I am obsessed with weight, I am a big believer that a lighter plane flies better. I have made this mistake before when glassing center joints by using fast cure epoxy like a 5 or 15 minute, I won't make it again. Use slow cure epoxy (thin like maple syrup), use as much epoxy to wet out the glass completely. At this stage you are going to think you have put on too much but its OK, use paper towel to soak up the excess epoxy. This will do two things. Push the cloth against the surface, and gets rid of unnecessary and heavy epoxy. Paper towel is the most important tool for this job. Just be patient, soak up epoxy little by little until the excess is gone. You will be able to tell by looking at it, no shine.

The downside of using thin slow cure epoxy is that it wants to drip and run everywhere. plan for that. Have gloves and paper towel. tape off areas do avoid any mistakes. The Epoxy WILL bleed under the tape, I'm OK with that, small price to pay for saving some weight.. Hopefully the lacquer finish will conceal the bleed.

Fiber glass cloth plus the Epoxy added 9g. . . .This is it, I will NOT be adding additional coats of epoxy to fill the weave for ascetics, this is not about looking good, but flying good.

Glue & Fly Series - Maiden Flight of our Latest F-22 Micro V1.5 Airframe



Here is a link to the Video:
https://www.youtube.com/watch?v=mUe-QzTBiRg

I'm always a bit nervous performing Maiden Flights via Line-Of-Sight.
My Line-Of-Sight skills have greatly improved over the past 3-4 months but I still have a long way to go.
The All-Up-Weight of this Micro Parkjet is 119 grams with a 2S 450mah 65C LIPO.
The Thrust-To-Weight Ratio with this 2S LIPO is 1.3:1
This is our trainer setup for this Micro Parkjet.
For an Intermediate to Advanced setup all you have to do is replace the 2S LIPO with a 3S LIPO ;-)
The 3S LIPO we will be using is a 450mah 65C LIPO as well.
I will post additional flights of this Micro Parkjet in Trainer Setup and then it will be time to perform the Re-Maiden with a 3S LIPO in the Intermediate and Advanced setup ;-)

My observations on the Maiden Flight:

* The Parkjet was slightly tail heavy
* The fact that the plane was a bit tail heavy made the controls a bit twitchy
* After the 4 minute flight the LIPO Cells were at 3.7v per Cell
* Estimated flight time with this setup should be approx. 6 minutes if your in the throttle a lot like me ;-)
* With a Micro FPV System operating at 25mw it will probably be around 5 minute flights ;-)

I'm pretty darn happy with the way this Micro Parkjet flew on the Maiden Flight!
If someone with my Line-Of-Sight skills can fly this Micro Parkjet on it's Maiden Flight and also perform basic Acrobatics with it and not have any problems, then a seasoned Pilot will certainly not have any problems ;-)


Stay Tuned ;-)

Build, Fly, Crash, Repair, Rinse & Repeat!

Happy Flying!
