With the correct choice of airframe, it is possible to fly with almost any engine. A slower flying aircraft with large wing area is more efficient and can carry a heavy engine with low power. The Wright Brothers had 12 HP from an 82 kg engine.
 
Hallo,
I have a question machining the Rear ball bearing housing.

is this my TCD and my starting point for milling the key way and boring the 18 wholes ?
 
I have an other question . This are the dimensions from my bearing :
5/8 x 1 3/8 x 11/32.
Is this the right bearing ?

That’s the result if the last step is wrong .
 
Now the summer is gone . Time to make further parts for my engine.

the bearings i used were of the rubber sealed type as i found it impossible to effectivley seal the rear bearing as in the Chenery drawings it meant a slight modification to the housing i think around 1/32" deeper?
 
Yes I will check my paperwork the bearings are stock items over here the only difference is the width Od & bore the same I will be in touch with regarding this matter shortly
