Engine positioning

I think that it's designed for OK Cub .049 with external fuel tank.

Model was designed by Walt Musciano, so I searched several model plans those designed by him, but no engine brand had been mentioned but only Half-A or .049 written on plans.

I believe you may be correct Levent. I have a NIB ok cub WITH intregal fuel tank that looks like it would fit perfectly without the tank. I've read nothing but bad about those engines. I doubt one would even fly this thing!

7 inch chord x 24 inch wingspan = 168 square inches, about the same wing area as the early 1950's DeBolt All American Jr. It used the weaker powered .09 class of then. I am thinking that the understated engine size range listed by Blackhawk retro kit manufacturer is stated for the later engines, more powerful ones, Tee Dees and Norvel Schneurles.

An A.C. Gilbert .11 would be about right, and fit the width. Might have to mount the tank with top a touch below the venturi. That type wing area, an early 1950's McCoy .09, Fox .09 side port would work. These engines are mild power-wise in the .09 class. A Herkimer OK Cub .099 would work, too.

Well 3/4" is a little much my Baby Clown is 5/8" hole a medallion .09 is 3/4" at the crank case would bee tight fit . If you have a mail system out there you can order in the stuff for covering !?!? I am looking through some my stuff for you a inexpensive engine worry bout the covering for now .

OhBee,

I had to carry the QT size part number to my vendor. He acted like he never heard of it. The "tell" is that he has other products from the same manufacturer (I think PPG). So once I pointed out that he already carried the manufacturer's "other products," he called the warehouse with the PN I provided. Two days later Unlocked up the purchase.

This is my local Mom and Pop hardware store. What Big Hardware retailer do you have nearby? Home Depot, or Lowe's? PM your ZIP code...I don't think I still have your physical mailing address, but using the zip, I can run a "find vendor" on Deft's manufacturer website for "closest vendor."

Of course, that vendor will most likely be told of the existence of this stuff before he does a look-up. Mine just said "I think I've heard of this stuff from an old cabinet guy," after he placed the order.

Home depot says they have it...till you go to the store and they  tell you its online order only. Nobody will even order for you!  I can't do online shopping.  I pretty much give up on this whole thing....too frustrating. We've hit every concievable store in 3 diff towns. They're all clueless and too put out to help anybody.

I just called. These guys have two quarts and f Deft, PN DFT010 in stock. Ask for Jeff.
