Well, I'm back again.
I'm glad to see the forums are still sailing along smoothly. Figured I'd drop at least one of my awkward toy grade retrofits in here for now.
For those who know, WLtoys manufactures a series of tiny craft to compete with UMX in some aspect, i'm guessing...
One of which was their long time staple, the F949. A simple Cessna, with a gearbox designed to carry three 7x20 motors in parallel.
To be fair, that just doesn't cut it with me.
This is how it all began, or something like that.
Right, so a friend of mine passed me a bundle for a ZOHD drift, IIRC. After a few years of careless, and completely disordered "planning" I decided on the perfect platform to mount the motor.
Initially, I had to do some... somewhat careless surgery to yank the old gearbox, and existing hardware, sans servos.
I ended up using the existing [dumb] servos, on the premise that I had some other servos with blown teeth. I popped the logic boards out of the bad deals, and connected them to said servos.
I shoved one of my full range Hitec receivers under the hood, as well as a tiny servo for an impromptu drop system. and I was mostly complete.
The next step was finding a controller small enough, yet beefy enough to drive a motor capable of peaking at around 120 watts. Simple enough.
I jumped into illustrator for a bit, to scratch together a design for a motor mounting point. Fair enough.. Sliced it out a few moments later, and glued the entire assembly in.
To be fair, she weighs in at 110 grams, before I was forced to install the struts.
I was forced to add struts, since... either the 4th or 5th flight ended up in a random catastrophic wing fold. I was clearly expecting it, but it was surprising nonetheless. can't have variable geometry wings of this magnitude without some sort of failure.
45-50 degrees is a lot of travel.
I ended up splitting the firewall in half.. which was quite an impressive feat. That's a piece of 1/8" ply.
Since I fabricated the struts, I've put it though things that would have pulled the wings completely off, with zero issues.
My next step is to get my hands on two more of these little airframes, as I'm about to scratch together a twin version.
Anyway, THIS is the album I've been dumping the photos on. Most of the stuff I've not posted about it can be found there.
