My current project is to not contract a virus.

Other than that, today was Free Plane Friday for me.

I was casting about last fall, lamenting the lack of a winter model-airplane-project.
My friend, Mephistopheles (not his real name) and I struck a deal: his plane, his engine, my time, our flying, to reconvene March 2020.
I held up my end of the bargain. Mephistopheles did not.

In March, when I presented Mephistopheles with the finished product ready-to-fly, he gifted me the project.
He insisted.

That was Free Plane #1 flown earlier today; vintage Bridi tail-dragger, very low-hours Saito 91 four-stroke.

Plane #2 was assembled from plans by another friend, Bugs (not his real name).
'Assembled from plans' does not properly represent what Bugs did here.
'Assembled from plans' simplifies his process like the first step of automobile engine replacement simplified to 'Remove engine'.

Bugs' airplanes are expertly assembled.
And all sport amazing covering-jobs.
And all are flown by Bugs. And flown. And adjusted. And flown.
His planes are rarely sold, and when they are sold they command a remarkable price.

Because they are remarkable model airplanes.

Bugs arrived at the airfield not long ago with a masterpiece to give away.
I, perchance, had just smashed my sixth Decathlon. (That count doesn't include smashed-rebuilt-smashed).

They pack so much easier after you smash them.

I was gently placing the Decathlon carcass in the trash when I ran into Bugs.
He saw me, saw some of my best demolition-work to-date, and was suddenly wishing that I had not seen him.

Bugs had a very nice model airplane firmly clutched in his hand.

He was very reluctant to let me know that he had brought this airplane to give-away.

It was apparent that I had room for an airplane.

After a brief conversation about a proper engine for the airframe-only offering, Bugs' only hope was exhausted when I just happened to have an OS Max 40LA engine like the one he built this airplane around.

That was Free Plane #2 flown today, Free Airplane Friday.

Hi.

My name is Seth.

I fly toy airplanes, and I eventually smash them all.

Nitro is for me. I mix in a little electric, too, as the convenience is convenient.

I talk too much and will funnel some of that energy towards a blog about my model airplane projects, trials, and tribulations.

I won't include lurid details of my harem, my life of crime, or recollections from my time as a CIA counter-double-reverse spy.

When the mechanics of a plane work well flight after flight, day after day, through the course of a flying season, you know you have a well engineered machine. It's easy to get complacent, though, and forget to check components that may be getting worn out. The smallest detail can become a weak link that brings the whole enterprise to a sudden, and terrifying, end.


As an Advanced IMAC pilot who pushes my planes hard through endless aerobatic maneuvers, I learned the other day there is no room for complacency in this sport.



Exhibit A: the ubiquitous, and ordinary, Velcro strap.


We rely on it to hang, hold, wrap, or support a wide variety of things. Since all of my planes are electric, the biggest job they have is holding back as much as six pounds of batteries (in my 104" Extra) through high g maneuvers. When the straps are new they have a great deal of holding power. After repeated strapping and unstrapping, however, the hook and loop fastener begins to wear out, and its holding power gradually weakens. It's that gradual weakening that is easy to overlook. It's easy to miss, until one day it can no longer hold back the forces generated in a typical aerobatic flight.


Exhibit B: the negative snap roll


A plane doing inside loops and positive snap rolls will see very little, if any, negative g's. There won't be much strain on Velcro holding batteries down on the deck. Fly an outside loop from the top, especially one with a negative snap on the bottom, and suddenly the negative g's are through the roof, or the canopy. The strain on Velcro is immense, and the consequence of it letting go at that moment are very bad.


Exhibit C: EF 95" Extra 330SCE, with 630+ aerobatic flights, after a flight with worn out Velcro battery straps (see photos).


More details on the latest incident involving my 95" Extra can be found here.


Anyway, it's time to consider a better alternative to, or periodic replacement of, the humble Velcro strap.

Due to staying home I've had a lot of time to refocus on my CMP Me-109 project. Has anyone had experience they can share about building and or flying this old ARF?
I have a new, never run Saito FG 30 gas engine in it. I got the engine back when they first came out. I've heard that there may have been problems early on with this engine. Does anyone have any experience with this engine? Thanks
I have a pilot bust from Aces of Iron I'm going to paint for this model.

Hello,

I bought a 100cc (35%) Pilot Extra 300 many years ago. I think I bought the kit in 2010, after many years of waiting for other people to help me fix my DA100 that was badly damaged when I crashed my Hanger 9 Extra 260 I finally found someone who could repair the engine for me within a few days. I had kind of neglected the hobby a bit and started to get back into the hobby once I had the DA back. I finally completed the kit and had her in the air on 14 February 2020, 10 years after I bought the kit.

I had a JR radio system in the Extra and recently upgraded to the Jeti radio systems, thanks to the recent worldwide pandemic (Corona Virus) our country is in lock down so I haven't flown with the new Jeti Radio System. Once I have a few flights under the belt with the new radio system I will definitely post a review of what I think of the radio.

I can confirm that the 35% Pilot Extra 300 performs really well with the DA100 swinging a 25x12 Three Blade Biela Standard Prop. This is my first Pilot kit and I am really impressed with how easily the kit came together. Everything fits perfectly and there is plenty of space. I will share some pictures of the plane and the setup I have.

Regards
Charl

Can someone tell me how to connect an Aura 8 stabilizer to a PowerBox Cockpit Competition SRS? I am using a JR 9503 Transmitter and three Spektrum Satelites on the PowerBox. I guess what I am really asking is: can this be connected through a single bus or will I need to plug the individual servos into the Aura 8?

Thanks,
