Dude its all good, and like I said I do agree with your point as the only proper way to balance a nitro motor is with the proper equipment. To answer your Question the pictures are of mods done with a cnc machine and as far as how he balances his motors, well I will let him answer that , But it has been rebalanced. I would like to point out the Epic EP1800 P an Engine which at one point was on every board on the net, I have a few and stock, the engine specs: 1.8 bhp @39,000 with a max 44,000 rpm (Stock red head). The platinum was the last produced and the specs were all over the place Trin had em for 2.0 bhp @40,0000 and 45,000 rpm max, but towers spec sheet showed 1.9 bhp @ 39,000 and practical rpm: 3,000 to 44,000 and high rpm: 45,000 ???? so who did what where eh? The engine did at least have 1.8 hp at 39,000 rpm and turn up to 44,000 rpm and for $229. and under (I have seen them for 149.) and thats a lot of bang for the buck. I will put two pics here and if you look close you can see where drive washer is drilled (balanced from manufacturer) This is where what I have said to jim over and over about engineers and math, The engines at the conception point are balanced (proto type) but after that it is production and standardization. The factory equipment programmed to make each part like the original (proto) so in theory already balanced, now do they fine tune from there??? I would like to think that there is some form of q.c. that checks the parts prior to assembly but I have never been to any to see for myself. FastRcCars[>:]
