I agree. The WMV format is amazing, and plays on most Windows machines. Microsoft "gave up" on the old AVI format is my understanding.

Like Keith said most of the noise is from the prop hitting the air coming off the trailing edge of the wing. But a little of it is from a small prop spinning fast, where a larger prop at less rpm's can create the same thrust and speed but be quieter. Unfortunately not really practical for the Wingo due to prop clearance issues.

The power setup on my Shocky is a direct drive EFlite Park 300 with GWS 8x4.7" prop and 2S 800 lipos from CommonSense. Would work good in a PicoMoth too.

One of the guys at our field tried the hotwheels radar and while it works okay for the TM and other slow planes you have to be right in front of and pretty close to the plane to get a reading, so it gets a little scary with bigger faster planes. He decided it wasn't worth it and took it back.
There is a thread around here about real radar guns for about $75 IIRC, I think it might have been by Boomer. The better guns sound like they work a lot better.

I am really surprised you can use a radar gun on a foam based object, such as the little Tiger Moth. I realize there is some metal reflective surfaces in the plane, but I would think you would have the be in close proximity with the plane before being able to get a "reading". However, this is just my ignorance talking, as I have never used a radar gun before and am really not versed in their performance capabilities.

Thanks for the info.

There is not supposed to be any metal in a baseball or tennis ball either.

Yeah, you are right. Never really thought of it that way. Thanks for the new perspective.

Also, that Hot Wheels one states something about scale speeds, does that mean if I drive my van next to it at 20mph that it is going to say 240mph? I only glanced the box as I was passing by it.

Well... I've done it.

I used to be able to tell when something was off, but now I find myself ashamed to call myself a builder and a pilot.

Ever since the incident up at the cottage, when I had to reassemble the wings after severe discombobulation, my moth has had this annoying tendency to roll. Now I had eyeballed the wings to make sure they were kosher, so I assumed the cause of the unplanned aerobatics was heavy sidegusts, and I had managed to account for them and get her back on the ground on all these occasions. There had indeed been a lot of wind, so this probably was a factor too, but this morning, I decided to get up at dawn to avoid the eternal blasted wind. The air was dead as can be, and lo and behold, she kept flipping over to port and despite my attempts to right her (I think she was doing that herself), I dorked her in at a good clip.

Wings everywhere, gearbox cracked, motor stick impacted back a half inch into the firewall, damaged to the underside of the fuse where the pack went through and the cowl has at least five good tears in it.

The AOA must have been really off from one side to the other. The motor had a healthy amount of right and downthrust so it wasn't that, but... cripes.. I should have seen it, I should have felt it... *sigh* I kept saying I needed a bigger aileron bird to fight the winds here, when all I needed was a properly screwed on head.

It is repairable, but it's going to take a while to do it right, and she'll never be the same again... Ideally a new set of wings is in order. Ugh.

Ack! Sorry to hear that, Kitty. It really does suck when you can't blame anyone or anything other than yourself. My first major prang with my moth was due, primarily, to my continuing to fly after a smaller crash had messed up the rudder centering. What a sickening feeling. I'm sort of surprised, though, that there would be enough warp in the wings to cause that without it being totally obvious. Maybe it wasn't the wings? Can't think of what else it might have been, though.

Ah yes, but the very nice and convenient thing about Mothy. If you can't repair and rebuild it, a slope glider version is always in the wings awaiting your creative talents. Ever onward, upward and never too much downward is the ticket.
Good luck,
Rich

Sorry about your Mothy Kitty. I'm sure you can get her fixed as good as new.

Who needs new wings? A little poly glue and some scotch tape and they'll be fine.



TEOR, the HotWheels radar gun reads in either scale or actual mph, selectable by a switch. The main problem is since it's designed to read speeds of tiny cars on a track the beam isn't very wide or very strong so you have to fly pretty close to yourself to get a decent reading. Also have to be almost straight on or the reading will be off. Fine with slow planes like the tiggy but with anything faster you'd have to have a lot of trust in the pilot.

WOW Kitty, Sorry to hear it hon. You'll have it back up in the air soon. That creative mind will get to working and it will get it all fixed right up. Was that the Fishie?

Wayne, man, seems kinda scarey to put yourself so close. I would take a lesson from Mythbusters on that one, and just mount the gun onto a camera Tripod for a pass or two while standing a good deal far away.

Well.. I *could* reglue them, but it seems whatever warp crept into them during the "treeing" is only getting worse with each subsequent repair. At a couple of bucks per, replacement wings are the way to go I think. The current ones have reached a high level of epoxication. I know other glues are lighter, like my beloved GWS contact cement, and I use them wherever I can, but nothing beats the strength of epoxy, espcially in the flying conditions I'm usually in. :\

Better to get a nice crisp set, nice and true. The fuse is still in good shape. Now the question is, do I get white wings and paint them a nice plain silver? Or do I get yellow and redo my Lil' Fishy scheme on them? I do find the yellow skin of the painted wings makes them that much tougher.. hmm...

LedKitty,

Really sorry to hear about your TM!

I gree about a new set of wings. My vote is to, get yellow and redo your Lil' Fishy scheme on them. No one can duplicate your beautiful work.
