Peck One Night 28

[CPL]

Has anyone here built a Peck Polymers One Night 28? If so do you have any suggestions or problems to watch out for? Also, what about other P-30 kits? What are the good ones and what are the ones to avoid?
Thanks, Chris

... I built one, and had some beginners build them too. It must be nearly 25 years in production, still selling, so it can't be too bad.

If I remember right, they all flew away (not all at once!); spend the winter trimming it for indoors (takes a fair-size hall), then increase the rubber and right thrust, yours will likely fly away, too. :D

We have the weather here to fly 12 months a year. First local competition is the end of April at Seguin. That should give me plenty of time to build it, fly it, crash it, rebuild it and fly again. Thanks

Fit it with a dethermalizer, unless you like seeing your model fly away.

Any suggestions on a D/T setup on this model?

This thread has links to a Tomy toy D/T and a Silly Putty D/T
If you can find one, one of the button timers are great.

I think I would D/T the wing like the P-30 guys do, sometimes a stab D/T is not enough in a strong Texas thermal.

One more thing, use the D/T on every flight even the low powered test flights, ask me how I know that:rolleyes:

What can the Tomy timer be found in? What about commercially available timers, either electric of mechanical?

Flailinng - Do you compete at Seguin?

... the old reliable fuse: reliable, cheap, available. Last I looked, Sig still had it in their catalogue. Don't forget to use a snuffer tube, the old days of letting the burning end drop to the ground isn't politically correct anymore. ;)

It has been a few years since I have been to Seguin, the Texas group has 3 clubs in Houston, San Antonio, and Dallas we used to rotate the contest between the three of them but it kind of died out. I want to start competing again so maybe I will be there once more. I do rubber scale, peanut scale, and power scale. and of course the mass launch events. As far as the timers there was someone here in Texas who made a button timer a really slick viscous fluid timer that is very lightweight, I don't know who but I will try to find out.

Forgive my ignorance, but being an aspiring F/F'er, and none too experienced, may I ask what a Dethermalizer is? I figure it cuts lift or flight time (taking this out of context). Thanks!

If a model flys into a strong enough thermal, it will fly away (a so called "Out Of Sight or OOS flight). It's a great experience, though you will probably lose the model (which is why you should always put your name and phone number on your models).

A dethermalizer or DT is a mechanism to drop a model down (out of a thermal) after a set amount of time. The timer function can be accomplished by a slow burning fuse, a clock wound mechanism (commercial or built from a wind up toy), something cutting or moving through a viscous material (silly putty) or electronic circuit. When the set time arrives, the mechanism triggers a change in the flying surfaces (trailing edge of horizontal stab pops up, or leading edge of wing pops up causing the model to stall, tethered wing wing pops off) etc., or causes a weight shift (nose ballast drops on a string tied to another part of the model).

I see. Interesting, but at my rate, it'll be a while until I need something like this. :)

Nick, You'd be suprised how easy it is to get a model OOS. I'm a beginner myself and have had an AMA Cub go OOS, got in the truck and chased, found it a couple blocks away.

Ah, well, the time has come, and I bought a SIG Mini-Maxer at the LHS. It comes with a D/T since it has a 4 minute and 51 second record flight time. So, I know Peck Polymers has fuses that I can get. Now what about this snuffer tube?

[Bob Chiang]

Hi Nick,

A snuffer tube is typically a length of aluminum tube with a diameter that is a snug fit for the fuse. After the fuse burns through the dt release, the fire is snuffed out when it gets into the aluminum tube.

The idea is to minimize the chance of starting a fire when your model reaches the ground (or starting your model on fire for that matter).

I personally won't use a burning fuse dt because of the fire danger.

PS. I've heard good things about the Mini Maxer. Have fun.

[T. Lyttle]

Fire from a snuffed d/t fuse is very rare indeed, certainly ont in my experience, and we have some VERY dry areas here.

As far as d/t models are concerned, I saw (I was timing it) a model fully into d/t going straight UP at one contest, flight was over 7 minutes on a 180sec max! Thermal city...
