There is nothing like a perfectly good engine minus 1 tiny bad part urges me to attempt an engine fix. Whilst changing out a piston /cylinder assembly on my O.S. 25LA motor, I noticed one of the wrist pin pads was coming apart. It seems the top of the pad is separating from the rest. This has...

As a high performance model airplane engine aficionado, I was wondering if say a slightly worn (less than a hard press fit) steel crankshaft ball bearing can be installed in an aluminum crankcase with Loctite red (stud & bearing mount) adhesive. Same with a lower connecting rod bronze bushing...

Andy, My experience is this statement is not true. What is common flying international class 2.5cc speed models is that after a 20 second engine run (at 39,000 RPM+) on regulation (4 parts methanol to 1 part castor oil fuel), the model lands & has noticeable drag in the engine bearings. The...

Hello there, Hard thick baked on castor oil can be removed easily by cooking for a few hours in a crock pot (slow cooker) usually obtained cheap from a garage sale or 2nd hand store. Use PURE ethylene glycol (anti-freeze) for the cooking solution. You only need to heat the glycol, (set on low)...

NO there sure isn't! Mine is the most "minimalist" area model there whilst still remaining stable. The acceleration is so quick off the ground the launcher guy has to leave quick as the model will be by in ~ 2 seconds! It pulls an awesome amount on the handle end too. Safety pull test is `63...

I have a much milled on latest version (3/4" crankshaft) Nelson 40 (6.5cc) Front Intake Rear Exhaust (FIRE) chromed alum. cylinder (AAC) motor. It weighs ~24 oz. without fuel & from a standing start has hit 160 MPH. It's 'potential' is quite a bit faster I'm thinking....

Thanks guys! You're a wealth of info. Cheers, Paul

Gentlemen, I am building some 1 oz. fuel tanks from thin .005 sheet material. I think I have tin & possibly steel. Of course, the tin solders easily with anything. The unknown material will not solder well at all with regular rosin core solder. It will however solder just fine with Sta-Brite...
