I blow up my ofna ultra lx2e nitro engine .28. I want to get a new one but not the same one, does any body knows what other engine will fit on my car and a good engine?.
A few years ago, I bought an RB Concept 1004-B C4 engine for my Ofna Ultra Worlds II. At the time it was one of the top 1/8th scale buggy engines. It was excelent with over 3HP. I suspect they are still producing top engines.
If you like to play, I’d look at a cheap 4 port engine. I had a Ofna Force P4 .21 engine. After running it for a while, I found where it had fuel stains and ported and polished it. Like this: http://www.nitrorc.com/mods/engines/trx15mod.html I also put an empty CO2 cartridge tapped into the block as a boost bottle. And last I added a pipe that went between the carb and the engine (I can’t remember what it was called). Unfortunately we lost our track, so I didn’t have a good place to test it any more.
