Hi Loray



Nice to see you are looking at a moose. Drop by and see me when you are back

up our way, perhaps at the balloon festival

Regards



Mark C

Hi Loray,



There is no "advertised" gross weight increase by Murphy with the extended

wing tip but it would theoretically.  I suspect the "extended" wing tips he

refers to are the new, optional, slightly droop tips that are approximately

9 inches more span than the original tip.



Another builder has extended the actual wing out one bay (12 inches) and

used the standard tip so gained about another 4 inches.



I don't recall a lot of water spray at all when flying Ron K's plane and it

has longer blades than the standard V530. I'll see if Steve is around, he

has a lot of time in Ron's and has longer blades for his too.



I know a few with the three blade MT props on floats, I'll see if they are

around also.

Steve pointed out that the prop on the Otter hangs down to the floats and

erosion isn't a major problem, probably due to geared engine and lower prop

RPM.  Seems the M14 would benefit from the lower prop RPM also.



He doesn't recall a lot of spray with Ron's Moose with the long two blade

either but this is on straight floats. It is probably sitting a little

higher in the water than amphibs would.



FWIW

Hi Scott:



Any light you can shed on prop clearance issues on floats would be greatly appreciated.  Some of the guys must have some time on rough water now.  Every water takeoff in the Philippines is rough water, with open ocean and constant trade winds.  Downwind taxi turns with the big-tail 185 are challenging.



Hi Mark:



I'm in Singapore now, Bangkok tonight, and Manila on Friday.  But I don't know if I'll make it up for the balloon fiesta.  The amphib hasn't been flown for a while and the engine is still perserved.  Not sure if I'll get it un-pickled and thoroughly looked over before the weekend.



Regards,



Loray
