Lesson learned!

Trying to get the fuel line on the carb's barbed fitting is not something to try to do after it is installed into the boat.
Not enough room and it takes a lot of effort to slide it on. See orange fuel line in pic.

So had to pull the carb, brace the little fitting on the work bench, put some 2stoke oil on, and push hard.
Reinstall the carb and torque it down.

Anyway, lines all routed and clamped in place. Nice and tidy.

Figured out the throttle issue.
Had to move the servo end out one hole on the arm, and the throttle end in one hole.
Throws from fully closed (idle) to WFO!

Weather is supposed to be nice this week 70*, I can finally wet sand and clear coat!

Hope to get her wet by next month!

After the 13 mile fiasco, some documentation of tire compression with a typical payload. It clearly is a matter of traction vs stiffness. The flat treads need a lot more material to be as hard as the curved treads, but are necessary for any traction.

A tire with a slightly curved tread didn't get any stiffer. Changing the number & straightness of the spokes didn't make a significant difference. Putting the extra spoke material into more tread thickness might make it stiffer. Printing spoked tires with .4mm layers takes only 2.5 hours.

There is a new honeycomb design with a flat tread & integrated motor mount, but it takes 10 hours & the lion kingdom is low on filament again.

At the end of March 2021 I finally received my long awaited FMS Rafale

Here's my first Rafale vid showing that the plane is perfectly capable to take off from a rather shot grass field that doesn't resemble a golf court.

I'll share my mods and more info in the next posts!

I see routing suggestions on RCG and FB that real model pilots don't need autopilots or gyros. While I think a lot of models can be flown without them, I don't see a problem with using them. AS3X provides gyro functions but it is not an autopilot. I think of it as being a simulation of actual pilot actions in an aircraft. If you watch some videos of pilots (check out the YouTube videos of Trent Palmer or Juan Browne's Blancolirio channel) you will see the pilots make continuous inputs to the controls. While it's been a long time since I have acted as PIC, I do remember that as you learn to fly and gain experience, you do just start responding to the effects of he atmosphere on the airplane automatically. That's what AS3X does, it replaces you subconscious actions since your are not in the plane to act.

My Airfield Tempest 800mm (31”) Warbird would just never fly right. It only had one battery and a dedicated Tx that took 8 AA batteries. When it did a destructive nose dive it had enough cracks and bent motor shaft that I was done with it.

The electronics came out easily enough. It was like stripping out the nervous system of some kind of dead robot. The control rods were very long and thin. The ESC was more like a motherboard. However I was impressed with the multiple inputs on the receiver and the string servers.

"Chona" is a Ziroli 100" A1 Skyraider scale model. The Ziroli kit was built by Ramon Medina, one of the best model builders in Puerto Rico. The model was built around 2015. Since Ramon built it, I shared with him that if he ever sold it, I would be the 1st in line. I purchased the model in 2017, some months before Hurricane Maria struck Puerto Rico.

Ramon is not a fan of installing any external payload in his models. Even thou he had made the payload pylons and missiles for the A1 Skyraider to carry, he never installed them. This is one of the things I added to the model. I added the payload pylons and installed E-flite payload releases. I made 2 droppable Napalm bombs for those two pylons. I also finished and installed the missiles and rocket tubes in the remaining wing pylons.

In 2017 I gave the Skyraider my maiden flight, (it had been flown multiple times before by Ramon). The model flew perfectly. I did experience scary moments when prior to the 1st landing, the main landings didn't fully extend themselves. Ramon, who was standing right next to me, told me that this was normal. Ramon explained that the landing gears and big 5.5" wheels created such drag with the airflow that the gear would not fully extend itself unless you slow the model significantly. Taking this measure, the retracts would be able to win over the airflow and fully extend themselves. This really gave a goosy feeling since I was not going fast when I attempted to extend the...Continue Reading

In this a small build up log. I’ll go ONLY through the issues in the building manual that I have encountered and can give some advice on (The remarks could be also good for other TOPMODEL CZ models).
I have ordered the ADRIANA glider directly from TOPMODEL CZ shop. It was packed nicely and has arrived in perfect condition.
Building parts quality looks just great.
