First run of the YS .91 FZ! RAW POWER!

by greg on Dec.12, 2009, under Engines and Motors

Ok so after spending 2 hrs making my self $500 poorer due to needing a set of tires on my car, I drove down to Nexgen Hobby in Hagerstown, MD (http://nexgenhobby.com/) to get some fuel for my YS .91 FZ four stroker I put on my Extra 330s.

I picked up a gallon of Wildcat “Curtis Youngblood” 30% Nitro 23% Full Synthetic Oil for $27.00.  Not a bad price for 30% fuel if you ask me.

On the way home I got to thinking that the puny aluminum 6×32 Phillips head screws I used to mount the big 4 stroker to the engine mount  just wasn’t enough….so I stopped at Lowes and picked up some 10×24 “Grade 8″ Hex head screws and stainless “nylock” nuts.

Got home and went right to work replacing the mounting screws with the MUCH heftier hex heads.  After finishing, I pumped about a quarter tank of the Wildcat 30% into her and got going.

I followed the directions I found online for these “fuel injected” engines. Open the throttle to full, turn the prop over 10 times, close the throttle to Idle, turn the prop over another 10 times.

I attempted to start it initially with a few flips of my (gloved) hand, but had no luck.  I then proceeded to use my Hobbico electric starter and she fired right up.   Initial thoughts on the engine are OMFG!   I don’t have a tach, so I don’t know what kind of RPMs I was getting but spinning an APC 15×8 prop this engine can put out some SERIOUS thrust.  So much that I could barely hold onto the fuse with my non-radio hand.  Idle is nice and transition to full throttle is superb!

The high speed needle is sitting at 2 turns out right now until I have more time to get her dialed in just right.  It was about 30 degrees out so I got very cold, very quick and finished up after about 3 mins of running.

I cant wait to get this bird out to the field and into the air!

Getting back to my RC Airplane roots.

by greg on Dec.10, 2009, under Airplanes

Ok so my father talked me into getting back to my original RC roots of building, flying (and crashing) R/C Airplanes.
He happened to have a few Duraplane parts laying around so I have since built 3 of them, crashed 2 and rebuilt 2. See a pattern here?

Unfortunately the balsa planes (wood) don’t exactly bounce back all that well.

Below are some pics and vids of the planes.
