Thanks so much for all the info. I just need to break into this thing one step at a time like you said and not get overwhelmed lol. So I already have a set of both u.s and metric dynamite wrenches so I知 good there. The 5-40 screws I spent a half hour looking at my local hobbytown for them and quickly realized they are difficult to find, but I had the guy order me a set of 5-40 1/2 inch screws, I believe I知 getting a package of 8 of them, are the required screws that go through the engine blocks tops and secure it to the top of the engine mount 5-40 1/2 inch also? And would they require washers of some sort? Thanks for the info on the switch, like I said I have a lot to learn. I know there痴 a ton of different connections but I was familiar with the jr connections because of my losi 8ight t. So if I want JR connections I知 assuming I知 going to have to get a new switch with a jr style connection point for the battery, and a 5 cell flat pack with a jr style tab on it. And the lst did NOT come with any radio or tx, I tried plugging in my extra 5 cell(fully charged) directly to the my stock spektrum receiver from the 8ight rtr, plugged in the steering servos wire from the lst into that receiver, turned on my spektrum radio but nothing happened. maybe I had them plugged in the wrong way or something, I doubt all 4 servos on the lst are toast ya know?but maybe they are. Next, hopefully the spur gears on mine are the original tooth count, I got two clutch bells along with two flywheels from that eBay purchase, so when I eventually install the engine I guess I would be able to tell right away from the quality of the gear mesh whether I have the correct combination of spur and clutch bell gears? So many questions I know but thank you again for the all the help and I値l take your advice and eventually start a thread. You致e been a big help Im helping me along so far and for that I appreciate you! I値l check out the exploded diagrams for anything else I come across and plug away at it starting this week. Hopefully can still order parts from Amain and eBay if needed with everything going on in the world
