Dont think will fit my engine The one i need is 25 quids
the flywheel is one of the engine parts that's interchangeable between most engines mate, the one mike listed above is the right one, rcmodelz have 3 from what I can see , the one mike linked, the one that's modded for the rovan ezi starters at 15 quid and the lightened one for 25 quid, you don't really wanna put a lightened flywheel on the g320 engine, yeh it will spool up quicker but the g320 has a tendancy to run hot and a lightened flywheel will reduce cooling cos the fins have been machined down, all you need is a new flywheel at 9.99 and a new woodruff key, clean the key slot up on the crank and bobs yer aunty ,
How tight should the fly wheel be on.. As in proper hard crack till you cant turn the wrench any more ? Or tight enougth its not going to fly off... ?
the flywheel should be quite tight mate, tbh your better off torqueing the bolts properly to the Zenoah specs, the flywheel or rotor as its listed on the Zenoah spec sheets should be 10 to 14 Nm , but if your tightening without a torque wrench then don't swing on it cos you could damage the flywheel or crack it , it does need to be nice and tight though, and you could always add a drop of Loctite to the nut, just make sure the flywheels seated on the taper properly and that the woodruff keys still in position and seated in the slot and the keyway on the flywheel, the woodruff keys do have a habit of moving on these engines sometimes when you fit the flywheel as well, easiest way to check the key is in is to slide the flywheel on and then before you put the nut on shine a torch at the keyway and you will see if the key is in or not, heres a link to the g320 service specs mate, torque settings are on page 14 if you scroll down ,
Yeah, a new key and flywheel would be the fix to that. So I wonder if that meant your flywheel was spinning independent to the crankshaft, and therefore the spark was way off as part of your latest issues. Hope you can get it sorted soon.
I am a mad RC loving lawn mower racing lunatic with a desire for over-powered RC's.
tbh mate although I like the idea of a leccy start on a 1/5 rc, they never seem to work right, or always need a lot of looking after to keep em working right,
the one you linked was designed for the dragon hammer I think, but yeh it would work on other 1/5 scales, the other problems are extra weight and making em fit, they will take a lot of room up and some leccy starts need there own battery pack as well, by the looks of it even if you did go electric start your still gonna need a flywheel and key anyways,
