Default RE: 1/2A THRUST-O-METER

HI GANG! GUESS WHAT TIME IT IS?........ IT"S THRUST-O-METER TIME! Todays' competitor in the power lifting event is the NORVEL AME .061! This is the one that was in my 1/2A contest plane. I adjusted it for best compression with 30% fuel, ran it on bladder and here's what it did...

PROP RPM THRUST OZS

COX 5-3 21200 17.6

MAS 6-3 17900 20.0

MAS 5.5-4 22700 18.2

MAS 6-4 17600 19.2

ZINGALI 6-3 17900 14.8 OINK!

PUSHER 6-3 19600 reverse thrust

APC 5.7-3 21200 19.2

APC 5.5-2 24000 18.2

GRISH 5-3 24000 16.0

GRISH 5.5-4 17600 17.0

GRISH 4.5-4 21800 17.0

OPEN EXHAUST

MAS 6-3 18800 23.0

MAS 6-4 18500 22.4

APC 5.7-3 22600 22.4

APC 5.5-2 25600 22.2

GRISH 4.5-4 22500 17.6

I loaned my COX 6-4 out, that's why the results are missing, MAS 6-4 is a pretty close copy. The increase in power with open exhaust is relatively huge! A little bit of work to the stock muffler would pay dividends.
