Inspired by Scotto's EZ Duster, I'm adding a Mustang based Dusty to the build list as well.
Both the Kaos and Dusty will use a Mustang wing and empennage, the major change being wildly differing fuselages.
And to make it easy to find, the foam board Kaos is blogged here.

Funny how inspiration strikes - you can never tell when or where it will come from.
I came across a picture of Joe Bridi's classic 1970 Kaos in "Model Aviation" and built a PhoenixRC model of it.
All well and good - looks nice and flies like it's on rails - and Katana gave it high praise.
But then I noticed the simple boxy fuselage, and the light bulb came on.

Wouldn't it be nice as a FliteTest style foam board model?
If I built it in the same scale as my FT mini Mustang I could borrow the "swappable" power plant as a test bed.
And if I made the wings removable it would be great to take with me when I traveled.
Probably best to move the wings to the top of the fuselage then.
And get rid of the gear for simplicity.
And so it begins . . . . . . .

First step was modeling the HW (High Wing) version in Phoenix. Quick and easy, and not much difference in how it flies.
Then create a Phoenix model of a foam board version. Here I borrowed liberally from my existing Phoenix mini Mustang model.
And that version still flies great - no big surprise there.

Next the hard part begins - translate the Phoenix model into a real life model.
Meanwhile, here's what it looks like in PhoenixRC. Stay tuned!

Was gifted a partially built CHT Albatross by a generous friend of mine, so thought I'd document the build and maiden.
The fuselage was mostly complete, with the exception of final placement of electronics, servos and pushrods.
The aileron wing was assembled, but lacking servos and pushrods. The polyhedral wing was unassembled.

Had a recent laptop crash and had to reinstall PhoenixRC as well as all my 3D modeling tools.

For the record, here are my preferred versions:
- PhoenixRC - v5.5.l - reinstalled from post#1 of the RCG Phoenix thread
- Blender - v2.79b - prefer this over more recent releases
- Inkscape - v0.91 - prefer this over more recent releases
- GIMP - V2.8.14 - prefer this over more recent releases

PS: forgot to backup my saved emails as well as contacts, otherwise didn't lose any data

I've always wanted a small scale Spitfire, and finally had the bright idea to build one using the guts of my trashed UMX Yak-54 180.

Wouldn't seem to take too much work to create a profile Spitfire of the right scale and transfer the guts of the Yak-54.
Biggest complexity, I think, might be turning off the AS3X, or perhaps if I orient things correctly in the Spitfire it wouldn't make a difference.
Time will tell.

Time to dig out the Yak, take some measurements, and draw up a profile Spitfire.
Unless, of course, my EZ power plant shows up tomorrow, then all bets are off.

The EZ power plant did show up, so this project was shelved for a few weeks while I built the EZ F7F.
But I'm back on it now, and have created Phoenix models of both the Yak and the profile Spitfire to compare the flying characteristics.
Based on that, the Spitfire seems to fly fine at the same wingspan and weight as the Yak.
Considering making it a bit bigger, though, to give it more presence in the air. Need to give this more thought.
Next step is to generate plans for the Spitfire and then carefully transmogrify the Yak.

Just started yesterday on building a profile F7F using the FT EZ 3 channel power system.
Target scale is roughly 0.38 m / 0.48 kg. Draft plans / skin shown below.

Built a quick model in Blender and now have it flying in PhoenixRC.
Working on creating plans, and have the FT power pack on order.
Also have several sheets of foamboard in hand, so getting close to cutting foam and plugging in the glue gun!
And not that it matters, but all that was done in a single day.

But right now waiting for one of our cars to be serviced, life being what happens while you're making other plans.

I've always wanted a small scale Spitfire, and finally found the Mini Master Series Spitfire foamboard model by "grifflyer".
A FliteTest like build, it has a wingspan of 750 mm and weighs 302 grams - perfect!

This will be my first build from someone else's plans, so of course the first challenge was actually printing out the plans.
And even though grifflyer's plans weren't naturally "tiled", it was easy enough to print them that way using Adobe Acrobat.
As he so kindly explained to me in a PM, and is documented in his FT article here.

The series of pictures below shot his article, un-tiled plans, and tiled plans laid out on the floor.
When put together they are roughly 48 inches by 32 inches, which means I'll be looking for a couple of 24 inch by 30 inch (or so) pieces.
Clearly need to piece the pages back together and take careful measurements!

The series of pictures below shows Barry de Kock's solution for fixing a bad Phoenix cable.
Suspecting a bad connection, Barry took apart his connector and figured out which color wire went where.
He then tinned the bare wire ends, and plugged them directly into the female connector.

Note: not all Phoenix cables are the same, so your mileage may vary.

Cheers, rick

Received the FliteTest Mini-Mustang kit yesterday, including the Power Pack A.
Chose the A Power Pack as it can be used in both the Mini-Mustang as well as my existing Tiny Trainer.
The original Tiny Trainer power pack has developed issues - either a bad motor or ESC/BEC I think.
Built a new power pod in the afternoon using the new Power Pack A components.
Installed and tested that in the Tiny Trainer and hope to test fly it later today.

Will build the Mini-Mustang in a week or so, and document the process here.

Cheers, rick

This blog was originally part of the F7F blog, but moved here for clarity. Originally created starting 02/10/2018.

After building Phoenix models of more than a few foamies and after a bit of encouragement from "aelflyer", it's time to build my very own.
Decided to start with the FliteTest Hobbies Tiny Trainer as it offers three version in a single kit - glider, three channel powered and four channel powered.

Will document the major "ah-has" as I go along.
Important things right off the bat:
- buy the kit rather than building from plans - it seems much easier and faster
- build following the video step-by-step, and
- refer to the plans as you build as it helps to identify exactly where and how to cut

The kit has all of the foam cuts almost completed, including the ones that only go down to the bottom paper.
That's important as that cut would seem tricky to do if building from scratch.
You only need to free up each part with minor cuts, and then remove excess foam, which can be a necessary PITA.
My adjustable height desk is coming in handy, as for me it's sometimes easier to do things standing up.

Today's objective is to prepare the fuselage cut-outs and learn how to glue.
First image is the stack of Tiny Trainer kit foam boards with the partially cut stab / elevator clearly shown.
Second image is the plans - note that black lines are cut entirely through foam and both paper backings.
Red lines are cut through top paper and foam,...Continue Reading

Going to attempt to blog the Phoenix SU-35 build.
Blender will be used to create the 3D model, Inkscape to paint it and Phoenix Builder to make it flyable in Phoenix.
I'll describe each step, but not specific Blender, Inkscape or Builder commands as those are discussed further in my Liddle Stik tutorial.


Just beginning work on the Blender 3D model.
The three screenshot are of reference 3 view that I'll base the 3D model on.
Given I couldn't find any plans with sections, the 3 view and Freewing picture will be my references.
I size the top view for a100 Blender units wingspan, knowing that will scale correctly in Phoenix Builder.
Then draw a sizing box (yellow cube) that I use to get the side and top views accurate.
This is an important first step - get it wrong and you suffer later!
