Is there a way to use two FeatherWeight Trackers in a flight with just one Ground Station? For example, in a two-stage flight one tracker in the booster with a second in the sustainer. One way I think it could be done is to connect the ground station to the tracker in the sustainer, without...

I have an old Sky Angle Cert3/XL parachute that I just got out of storage for an upcoming flight. It is colored red, blue, and silver/grey. The silver/gray portion seems to be a rubberish coating over black nylon-like fabric. Every silver/grey panel feels sticky and is so sticky that it the...

I have a couple Proton that I've flown on single stage flights and am now looking to incorporate them into some of my staging flights. It seems using Deviation Percent as a criterion for safe staging is a good idea. However, the documentation is ambiguous on how it is calculated on-board. It...

I've been buying my LiPo's from Hobby King, but lately the 160 and 280 mAH batteries (and others) seem to be unavailable. Does any one know if this is a temporary situation or something we need to get used too? Also what are other sources people use. Thanks. ...Fred

Just wondering what LiPos people are using with their Raven altimeters. I know there is an issue with some LiPos sourcing enough current to fry the Raven. So far I've been using 1S 160 mah batteries with great success in normal deployment and staging applications. However, the 1S/160mah...

In the latest version of RockSim (v9.1.4) you can mark pods to be ejected, but I don't see how you actually eject them during a launch. I would expect that you'd be able to tie the ejection to a flight event, such as motor burnout or an elapsed time. Am I missing something? ...Fred

I just got a new Samsung Galaxy S5 to replace my Galaxy Nexus. Installed AltosDroid without problems and it seems to start OK. Thing is there is no soft menu key on Kit Kat (or maybe just the Samsung TouchWiz version). Without the menu there is no way to connect the TeleBT or select a frequency...

Just fired up FIP to program alt for launch tomorrow. Program said new version was available so I downloaded it. Trouble is Norton Sonar thinks its malware. This has happened before... Norton over reacting. Hoping to get an "all clear" from someone in the know. Adrian? ...Fred

Does any one have recomendations for simple (and free or at least cheap) software to plot flight data. The programs provided by altimeter vendors are generally decent for what they do, but I have interests beyond their capabilities. For example, I'd like to: Plot flight data and simulation...

Is there a way to export calibrated flight data from FIP into a CSV for subsequent import into Excel?

Does anyone know how to calibrate an ARTS? Although the Getting Started guide says this shouldn't be necessary, on flights where I fly two ARTS, their accel data differs considerably (baro data is practically identical). There is an opion under the Altimeter Diaganostic dialog to calibrate...

I had an unexpected thrill this week end at the METRA launch on Sunday. I was flying some two-stage low power kits while I was waiting for the cky to clear for the big stuff. I fellow METRA flyer said "I see you like two-stages flights, I have some 40 year old B3-0's that you might like to try"...

I finally reduced the data from all the flight cards. Below is a breakdown of flight count by loaded motor impulse. Under this system a two-stage C6 staging to a C6 is counted as a single D impulse flight. Cluster motors are similarly totaled. The few micro max motor flights are counted in the...

I just got back and unloaded the van and got a chance to count today's flight cards. The daily flight count totals are: Friday - 97 Saturday - 329 Sunday - 133 3 Day Total- 559. Not bad, especially when considering the weather forcast going into the weekend. I'll eventually post more...

Can anyone think of a way to airstart a small composite motor, say an E18? I'm thinking of a small two-stage project: G64 or F52 in the booster and a 24mm motor in the sustainer. I'd use a PerfectFlite timer to start the sustainer motor, but can't think of a low current igniter that'd fit...

So who's going to the first NERRF next weekend? I'm hoping for 10 flight over the three days: Exterme Performer on a J415 then again on a K550 PML Endeavour on a J400RR and again on a J415 PML Small Endeavour on an I161 Scratch 3 inch Endeavour on an I405 Terrier/Mini BBX on an...

Does any one know of a current source for C11-0 Estes motors? My usual on-line sources (A2Z & HobbyLinc) don't list them in their on-line catelog. I hope this is not another great Estes product that company management decides to discontinue. ...Fred
