Mach III- Norm Page


Looking trough the pages of RCModeler magazine, November 1975 issue, I've seen a small picture of Norm Page and a unknown Mach III. Does someone have information on this model

No info from me, sorry; but one quick observation... this particular photo montage is interesting in that 5 of the designs mentioned, to the best of my knowledge, were never published or kitted (Mach III, Hummingbird, Pantera, Checkmate II, Triple Trouble). However, it appears that some, if not all, are derived from the Mach I, or the Compensator, or some of the other pre-existing designs... similarities between all of them is obvious. The difference between the Triple Trouble and the Troublemaker appears to be so small as to be inconsequential.

Another observation - there are two different "Mach IIIs" shown, suggesting it likely wasn't a one-off tweak by Norm Page.

Can't say about the others, but seems to have read somewhere that Triple Trouble had a longer ratio arm. Mach III by Norm looks to have less sweep to leading edge and a larger tailplane. The other Mach III may well look different due to paint scheme.
Besides who can tell the difference between japanese models after BlueAngel won in Italy.

One interesting difference from the Mach I seems to be that in the Mach III the canopy flows rearwards in a continuous slope... i.e. a turtle deck... probably in search of more lateral area for better knife edge...

Sorry for the thread jack but that picture with Phil Kraft and a "Dirty Birdie" does not seem correct. Looked more like a variant of the Kwik Fli to me.

The Mach III did look like there is a turtle deck. The wing sweep and taper looked about the same like the Mach One.

Mike Mueller might be able to shed some light on Mach III characteristics.

No problem. With a thicker airfoil, it might be easier to keep up with than the Mach I.

There was a color photo in MANs captioned with Phil Kraft and his Orange Dirty Birdy. The top and tri-stock on a balsa build allowed for a lot of planing to make a well rounded Dirty Birdy.

Very interesting. I wish Bridi used some triangle stocks to round off all his designs. One reason why I am never too keen on the Bridi designs was the boxy look.

That is why David O's redesigns are so nice; he eliminates all the carving and sanding with rounded formers and thin sheeting.
Maybe he will post a copy of the original Brushfire plans and his redesign which is masterful in the weight reduction.

Phil flew his Fire Fli in competition until Bridi came up with the Dirty Birdy, then he switched. He finished 8th at the Nats with the DB in 1976. He used a Curare to finish 7th in 1977.
