I've never seen the formula, but if the fin semi-span is less than the airframe diameter, the root has to go up a LOT to counterbalance reductions in semi-span. It is NOT linear. W

My mistake - the Research launch on Sunday has been cancelled. Warren

It's not just fin area that matters, but semi-span. With a greater semi-span, you can do with a lot less fin area at the tradeoff of greater drag due to increased frontal area. Warren

Not a problem Scott - looking forward to it. Warren

Actually, we usually have the largest motor vendor in the country onsite for 90%+ of our launches. Tim Thomas of Giant Leap is a long time NCR booster and is almost always at our launches - particular...

I'll be there... possibly flying an L1300 in my 4" bird. Warren

Adrian, My thought is why don't you submit the Parrot to Tripoli as THE official recording altimeter for record flights? Let them test them against calibrated standards and mandate that IT is the "off...

By the official rules, ANY modification of a motor casing or closures is forbidden. This means that the many flyers who have drilled and tapped plugged forward closures for eyebolts or who have had cu...

This isn't a problem Mike and I can easily accomodate you on this, however be aware that this makes the motor officially "uncertified" and while NCR usually doesn't make an issue of these things other...

I have very thin mylar release - I believe it is .002. You'll need a couple thousanths of slop in order to even fit the thing onto the airframe as the irregularities in the tubing will probably be tha...

Mike, Like with the Tip to Tip glassing, I'd be happy to help out with this project. The key issue is having a mandrel to wrap around. 1st step - take the Mandrel (in this case a piece of the airframe...

Don't forget the step where you have to "Compile" the engine files before Rocksim can use them. W

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 a...

I'd definitely go ahead and do that if I were you... current record is 5967' for SSS and 8975' for SSSS.... pot is over $200 for SSS and right at $200 (I think) for SSSS. Potential for those that care...

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 d...
