Adrian, In your model rocket configurations, the altimeter is in the same envelope of the airframe so it sees the deployment charge and is directly affected by it. Would the reading be more accurate if it was isolated from the…   Read more»

Thanks, Mike and Warren, for the constructive feedback.Mike, help is on the way in the form of a PC interface program that Jim Yehle has been kind enough to provide, which will simplify the downloading and interpretation. It’s about 1…   Read more»

3) I’ve also heard the complaint that the Parrot is an unfair advantage due to its light weight and lack of a heavy external battery when compared to the average flyers’ Missileworks or Perfectflight or Adept with an external battery…   Read more»

Adrian, I do want to ensure to ensure you don’t take any of this discussion personally – at least on my part. I have never thought cheating was even a part of this discussion, at least as far as you…   Read more»

As an afterthought, I proposed in my R&D entry at NARAM 50, that for the NAR to accept altimeters for record attempts, to get rid of the need for theodilites, that a pressure chamber be present at a meet, and…   Read more»

I had the same thoughts about a conflict of interest, but on the other hand technology normally gets driven by a person which can not acomplish his desires when other alternatives are not available.Be that as it may, after trying…   Read more»

I may have a somewhat different take on the record list than some people. Some view it as a contest like the upscale contest, in which it’s possible to exclude some people from participating. I view the list as a…   Read more»

I have an inherent conflict of interest, I wasn’t there, and I recuse myself. I’m sure smarter folk than I will apply the rules (we do have rules somewhere) and whatever they decide, go for it. This is a hobby,…   Read more»

I’m all for Adrian’s Parrot to be honest about it and I do believe it is more accurate and provides additional data in the form of the 3 axis accelerometer to back up the baro altitude.That said, I don’t believe…   Read more»

So after reading over this I think there probably is a simpler solution than banning an altimeter flown by the manufacturer. When digital photography came of age it just so happened that all truth in photograph was lost. You really…   Read more»

My biggest recommendation to him is to provide a direct reading of altitude either via beeps or flashing LED as other manufacturers do or a plug-in LCD display that reads the raw altitude. I think it’s an excellent product, but…   Read more»

The discussion I had with Jim was more related to the fact that the standard atmosphere model is calibrated at a specific temperature – I can’t recall what it is, but I think it’s right at freezing. However, most flights…   Read more»

I’m glad to see that Adrian is not looking at temperate ‘adjustments’ for any record claims. As pointed out, this would be a huge difference to the altitudes seen from altimeters that have been used for Tripoli and club records…   Read more»

Ed it was only 1.3-1.5 miles away not 3. a lot of the points on the map are not clear as to what they are.

Following John W.’s logic that it is really hard to drift 15,000′ away on a 9k boost another data point is John Bixler’s Junior flight on Friday. He flew a 54mm diameter rocket to 22,312′ and recovered 1.72 miles due…   Read more»

So a 4 mile cylinder to 20K and a 10 mile cylinder to 35K. ExcellentW

North site AOO is a two nautical mile radius for 20,000′ AGL and below, and it is a five nautical mile radius when the 35,000′ AGL windows were used.

Well I can see at least 4 people in NCR who have their eyes on altitude records who would want one within the next couple months… John Wilke, Adrian, Chad and myself… and probably more.I would assume TRA would have…   Read more»

James – what you’re saying about having to use a Tripoli certified and owned altimeter is the one that makes the most sense although it also is going to make for a logistical nightmare for Tripoli.WarrenThey do not think so…   Read more»

I’m not 100% sure about the AAO during the 20K waiver, but I do know it was 5m radius when the call-in to 35K is active. I would expect it is 3m radius and not diameter.Personally, from all that Adrian…   Read more»
