Thanks KTM, hoping to maiden tonight.

The soldering I'm actually pretty good at and wasn't too bad. Yes, the final tie together had to be done on the plane. The biggest problem was trying to strip those mil spec wires that close to the fuse. Have a nice solder station, great dykes, good tools for cutting the foam, etc...But I realize now that I REALLY need a set of these. Would have easily cut 2-4hrs off the total job. Amazing how much faster things go when you have the right tools.

Full write up on the job in the 38" Slick thread, page 27.

You mean use the speed controller from the board of a servo? I'm not sure how you would control that. A servo runs the motor if the incoming PWM and the measured position don't match - otherwise the motor is off. And when it's running, it's running with full voltage. I'm not sure how you would keep the motor running. A better idea would be to simply use the servo to turn a pot... but that adds mechanical issues.

Damn you. Amazon Click Once is evil. Have one on the way. And while I was at it, some new tips for my soldering iron, and a new butane powered soldering iron. $100 out the window just cause I clicked on a link.

Speaking of the right tool for the job... Butane powered soldering iron with the "blow torch" tip installed is PERFECT for shrinking heat shrink, especially in tight spaces where you don't want to melt something nearby (like EPP). All the ones I see have adjustable flame, so you can dial in just a tiny flame and it will get the job done very nicely. Just use a little piece of card stock to shield and you are golden...

I've had one for like 10+ years and the valve on it isn't working all that hot anymore. Its more on or off, with a very finicky "somewhere in the middle" adjustment...

I hate doing jobs without the right tools... Probably the reason why I have so many...

Not the one's I've taken apart. If you disconnect the pot from the gears and set it to about the middle position, it works as a reversable, proportional speed control.

Here's a guide on how to turn a servo into a geared motor with built-in speed control for a small robot.

The motor keeps running until the pot matches the input signal, but the pot is now fixed so it stays running until you send it a signal that matches the pot.

Years ago I modified a couple of standard sized servos, glued old CDs to the output disks as wheels and made a neat little skid-steering robot to drive around the house.

Had fun last night, but was not in the groove. Was a bit too windy as well. Crashed the 33" and 38"...Only damage was a prop to the 38, and a small piece of wing tip that needs to be glued on the 33" The crashes made for some cool shots though.

OK I get it yeah, that makes sense... I won't be doing it though, because I have a couple brushed ESCs and those are much cheaper than the time it would take to modify a servo.

Just got this wire stripper in. Works AWESOME! Couldn't imagine trying to do small wiring jobs without it from now on...

thanks alot! It is just a simple wing I made but its motor is on the front to keep the noise down so I dont bother the neighbors. It has a kfstep in the wing and two angled fins. It flies nice and slow and looks good in the sky.
