A new Old time speed postal contest has been announced for 2.5 cc (.14 to .1525ci) engines, diesel or glow  This is a one design plane contest using the Megow PERKY designed by Matt Kania.  The Perky was kited by Megow of Philadelphia Pennsylvania USA in 1946  It was originally a control line Class A speed plane with a span of 18" and 64 sq. in area.  If you have never seen a Perky, take a look at the pictures below.

WANTED:  Plan agents for S. America, Japan, and other areas where there is interest.  Send inquiries to P.A.L.  Model Products at the address above.

Scoring:
Although strictly a one mile standing start timed contest, the sponsors P.A.L. Model Products are awarding a prize to the nearest average time (to even the playing field) of all entries and not just to the fastest.  This means that you do not have to have a super fast engine/airplane to enter and to WIN ! ! !
 

The Prize:
The organizers, P.A.L. Model Products are awarding a NEW IN BOX engine to the winning entry.  There may be additional prizes for the fastest diesel and the fastest glow depending upon the number of entries.
 

Construction:
You are going to have to work out your own controls (bellcrank, lead outs, control horn) and also tank details.  These are not shown on the plans.

The CG is shown on the plan but no lead out guide is mentioned.  Possibly the easiest method to locate the lead outs is to arrange external lead outs then hang the model from both lead outs and adjust the guide position until the plane hangs at about 1 or 2 degrees nose "down".  This will ensure that the model CG is slightly forward of the lines.

No engine offset is necessary but a small tip weight say 1/2 oz plus will help maintain line tension during take off.
 

Engines:
You do not need the fastest airplane to win the major award.  Any no longer competitive 2.5 cc engine can be used if you wish.  There is going to be a large differential in speed/times and I have no idea of what sort of times will be recorded.  I have heard of a ED racer 2.46 entry being built in Canada, a Nelson .15 and an OK Cub .14 in the USA and also a Rossi .15 from Italy.

There are not too many 2.5cc engines that are near contemporary with the PERKY.  The closest American engine, I believe, is the OK CUB .14 from 1952.

If we stretch the window to say 1953, then the number of engines (worldwide) in this size range - mostly diesels - available in 1953 or before is many:

Frog 250 (UK) Webra 2.46 Record Germany)
ED 2.46 Racer (UK) Sabre 250 (Australia)
Typhoon 2.5 (Holland) Metcore (France)
ED 2.49 (UK) Super Tigre G20 (Italy)
Eifflander 2.5 (UK) Elfin 2.49 Radial (UK)

If you want to go fast, use a more modern glow engine.  the open face requirement and pressure fuel system prohibition will some what even the score and some of the diesels from the 60's should perform reasonable well:

ETA Enya 15D
Rivers 2.5 Bugle/HP
Oliver DC Rapier
Webra Mach I & II Schlosser
Frog 2.49 BB Barbini
Allen Mercury Alag X-3

Among the glow engines are  Enya, Fuji, OS from Japan;  K&B, Fox, Cox from the USA; Rossi, Super Tigre, Cipolla from Italy; and several Russian and Czech Republic engines.

If you have any remarks or questions, email Lloyd and he will pass it on.
