Hi!
I'm a newby to R/C and to RCU. I have a Sequel 2M pattern plane with retracts, a Bully engine; I think it's a 120 with 2 glow plugs with a long tuned exhaust. The plane has been flown quite a bit in the distant past in competitions. I haven't flown it yet but before I do, I'm having an experienced R/C builder check the engine out.
I would like to know if parts are still available for this engine in case the engine needs a rebuild. If someone has the same or similar plane, I'm also interested in any other engines and sizes that would be suitable for replacement. I'm thinking that since the engine may need to be installed upside down, I may consider a 4 stroke Saito or other brand.
In addition, I'm interested in knowing more about the company that sold the model. Thanks for your help! Eric
Hi Eric. Welcome to R/C and RCU.
IMHO I'd ignore the nay-sayers and fly the airplane as is. Dave Guerin's Sequel is a great flying airplane and the Bully is a fine engine. I flew the final two years of my 20+ year pattern career (1980-2000) with an inverted Bully 120 Long Stroke powered OMS in Masters and F3A. That's it in my avatar picture. The Bully never gave me a problem of any kind. It never lost fire in flight and was easy to start. As a matter of fact, I hand started it 95% of the time after the first start of the day, even at contests.The only parts I ever replaced were glow plugs and maybe a set of bearings. The LONG Bolly tuned pipe was the name of the game with the 120LS. The 145 produced about the same power using just a Bolly muffler. The prop of choice for either engine was the APC 16x14.
As a matter of fact, I have a well used Bully 120LS I need to rebuild with new bearings and an almost new Bully 145 that will be powering the new Zimpro Viper 202 I'm building.
Enjoy!!
