Thank you very much Sir. Hopefully this Sunday  if all goes well.

Very nice sir , is that a electric prop on cox 049?

Waooooo!!!

Thanks Jana. That's a APC 6x4 not sure if it's electric. Will not be using it though. Will be using a Master Air Screw 5.5 x 4.

Well.... Sir,
I am not sure what differences it makes to have what prop on the motor or the engine.... I know I am not exactly right on this issue..... For all my motors I buy props from HK and I do not like the shape of APC propellers..... Have used all other types including the 9x6 / 10x6 and 12x6 Nylon and glass fiber of Sharma's.....  I am sure the cox 049 is a small engine and it would not mind the APC propeller too.... correct me if I am wrong please.

You are absolutely right there Sir. Cox works just too good with APC props as well. Makes not much difference.
Peak RPM is though better with a 5x4 Master Air Screw or the Cox soft ones same size. Props supplied by Cox sellers are softer than electric   may be the Glass filled ones would make a difference in a better designs other than cox sure starts which have peak RPM at 19000.

Papillon Junior is also ready with all electronics fitted. Engine has been run two tanks and it runs good peak RPM with 5x3 prop.

Finally ready for test flight. Now my 1/2A lot is full for the time being

Maiden of Papillon Junior. This completes formalities for the Junior too.

Very nice sir 

Thank you sir.

Junior Papillon gets an engine upgrade to ASP wasp 0.061 from the earlier Cox to keep in pace with the Senior Papillon with Thunder Tiger GP-0.07

Unused engine mount which did not fit the TT GP-0.07 came handy in the mount.

Has done two tank initial run in on ground. After two more will take it for inflight run in.

So far seems very promising.
