Engine choice for Brodak Oriental?
« on: October 15, 2018, 01:42:46 PM »
     Hello All:

     Before I start building a Brodak Oriental, I would like to receive some feedback as to which engine may be the best choice from the following:

Fox 35 Stunt
 
OS 35 Stunt

Tom Lay OS-ST 40

OS 40 LA

HP 40

        I am looking for adquate power, easy starting and smooth running as the primary objectives.  I think thatI listed the engines in order of increasing power and weight.  The weight ranges from almost 7 oz, for the Fox and 9.3 oz. for the HP. 

        Suggestions/and or comments?

                                                                                                                                                         Tia,

                                                                                                                                                         Frank McCune

The Brodak 40 is plenty of power for an ARF Oriental, kit built is lighter and, the LA 40 is slightly more power so, from your list LA 40 would be my choice.
There will be a sunny day and we will fly our airplanes.

Frank - when I developed the Oriental ARF for John, I used a stock Fox 35 and it was perfect.
The  prototype came out nose-heavy with the Fox, a wooden Top-Flite 10-6 , a tongue muffler and a plastic spinner.
I had to add around 3/4 ounces of tailweight.
I don't know if the kit would build the same.
I would go with the Fox 35 or the Max-S 35.

Hi all.

I have a Custom ABC Gardner OS 35 + tongue muffler  #^ waiting for my Oriental. After tested it power is considerably increased from stock unit (donīt have a Tom Lay unit to compare, BTW).
ABC PS and Gardner rod let the oil content to be drop considerably......



My two cents.

Kind regards from Spain.

Manuel.

My Smoothie works very happy with a Super Tigre 46. No balance weight needed.

Hi Frank,
All of the above would work fine.  It really comes down to what you like.  My preference would be the HP with the ball bearings, very nice running motor that last forever with std (20%) oil content.  Also, you can run a pipe on the HP if you want.

Later,
Mikey
