Focus

[Jarvis Johnson]

Hi
Bill, I also use a Webra/Bully 120 in a ZEN 120. I just replaced my bearing in my. you can get replacments from Boca Bearing at 1-800-332-3256. Front bearing stock # MR60000-2RS (10x26x8) mm, Rear bearing stock # MR16004 (20x42x8) mm total cost was $35.00. the Bully 145 has the same bearings. So how does your Focus fly with at 120 in it ?
Could you E-mail my back with the Set-UP you'er using, I.E. engine setup,pipe length, prop size, fuel. I'm usig Cool power 15%, 16x12 APC
Bolly 2002N pipe.7900 rpm. But my YS 120 FZ has more power
 
 
Thanks
Jarvis Johnson

Lee,

I have a Webra Bully 120 that I've been flying in my Focus and it needs new bearings.  Do you know if they're the same for the 120 and for the 145.  Do you sell bearings for these engines?  If not, can you give me the part numbers and/or dimensions so I can order them?

Thanks, Bill

The Focus II (summer release) will have a slightly larger stab and taller/wider fin/rudder than the original Focus.  These enhance tracking and stability and we found we could do it without degrading snap and spin characteristics.  I flew a modified version of the original Focus that had some of these changes towards the end of last season.
 
I'd say build your original Focus as-is.  They fly great and the new mods are only incremental improvements.

Added fin/rudder?????
 
This plane need help with KE flight?  Will it KE loop with the stock set up?
 
I plan on using the 3M 1.40 that I just bought from Jerry (Thanks Jerry!) that should be more than enough power to KE loop this plane.
 
I and still in the BUILDING stage of my ARC.  Hate to miss out on any NEEDED mods.
 
Thanks.

Beef up the landing gear block.. We knocked the gear out of 2 of them a couple weeks ago at Ocala (mine included!)  Not exactly a flying characteristic, but a zero landing hurts!
 
I've also seen several folks that have added fin / rudder area.  And if you're running a DZ, you might want to shift the engine box back a bit to get the CG closer (mine has an OS 160 @32 oz, and I moved it back about 1/2 inch for very good balance). It also made for easier cowl fitting, as it now slips over and mounts through the fuse sides rather than flush on the front with the blocks and such.  HTH, Chuck
