I'm somewhat new to P-30. I have built and flown a Peck One Night 28. It flew pretty well however I bought a kit at my model clubs auction and are well on the way to completion. It is a Fun Bird 30. My question is regarding a timer. I have no practical experience selecting, installing and operating a timer. I understand what they do but that's about all. Any advice is appreciated.
Thanks

Gerry -

A timer on a P-30 is essential.  It is part of the de-thermalizer (DT) system.  It is normally set for two minutes and releases the stab so that it pivots upwardly and the model floats gently down in a horizontal configuration. Otherwise it will fly out of sight (OOS) in a thermal.

The simplest timer is a fuse.  There are also viscous timers, mechanical timers and electronic timers. Each has its advantages and disadvantages.  I prefer the electronic BBT timer from Starlink Flitetech.  It is very accurate and only weighs about 3 grams, with the battery.

How you set up the DT system has been written about extensively.  Try searching on the HPA web site.  

If you have no luck, I can direct you to resources.  

A pivoting stab will not save your airplane from a very strong thermal. I am currently building a P-30 with a pop-off wing. It will come down in even the strongest thermal.  Start wit the pivoting stab DT system. It is easier to set up and will save your airplane in most cases.

P-30 is a great event.

Freeflight.org technical library has a LOT of links that will help with details.  For your convenience I've added some of them below.  Note... I'd suggest taking a look at the entire library as there's an abundance of solutions for a multitude of freeflight issues - Wow that sounded pretty cool I think should be used as a tagline-
