Title: What class would these two planes qualify?
Post by: frank mccune on August 17, 2016, 01:01:35 PM: Hello All:

I have two beautiful planes hanging in my attic that have never been flown. The engines have never been started and are equipped with custom mufflers. I am wondering what class of stunt would the be flown in to meet the requirements. I am a beginner.

One is a Sterling P 51 and the other is a CG Shoestring. Both have new McCoy .35 Red Head engines installed and are ready to fly. I feel that I should get hem into the air. They will waste away while in the attic.

Suggestions or comments?

Tia,

Foxberg racing and OTS or Classic stunt.

Check the dates for OTS. I'm almost certain that the P 51 is later than the cutoff date for OTS. I'm less sure about the Shoestring.

If nothing else they're fondly remembered planes with lots of nostalgia behind them -- just getting them in the air and flying them for sport, or in Classic Stunt would be fun.

I looked for the Stirling P-51, didn't find anything.

Definitely take them out and fly them !!!!!!!

I will break in the McCoys prior to attempting any flights!

I have a couple of McCoy 1948 .29 Sportsman engines with new Bowman rings that I think would have more impact than the Red Heads. I also have 1949 and a 1951 Fox .35 and .29 engines that are in great shape. Perhaps these would be a better engine choice. The Sportsman engines with their rear intakes, do have a larger bit of nostalgia for me. Lol If I remember correctly. the Sportsman engine were quite weak when compared to the Fox engines.

What would be the better choice for old times sake?

Suggestions and /or comments?

Post by: Randy Cuberly on August 18, 2016, 01:03:10 PM: If the McCoys have good compression run them on 28% all castor oil fuel with 10 to 15% nitro and they will be far better than the other engines. If they don't have good compression (good piston cylinder fit) you can have them chromed and fitted and they will be great!

If you don't want to fiddle with them and they don't have good compression there may be some folks around that will buy them (cheap of course)...then use the Foxes although they are poor choices for profiles! Vibration and the infamous BURP can get ya'.

Post by: Garf on August 21, 2016, 09:37:01 AM: I have 2 of the McCoy Sportsman .29 with 45* rear rotor. One was ringed and one was a rare lapped model. According to George Aldrich, the lapped models were chromed and took forever to break in. The ringed one was a total mess. Not even Frank Bowman was able to fix it. The lapped one was almost new. I flew it a few times on a Guilliows Galaxy. It wouldn't run steady. Most likely not broken in. Plenty of power for the Galaxy.
