So now you can use a suitable and comparable replacement, but you do accept the responsibility for getting the correct substitute. Rotax used to call for Loctite 5910 for sealing the gearbox and in a few other places. The problem was it only came in a 300ml tube which may last most people a lifetime and then get handed down to someone else. The US replacement is Loctite 598 and can be purchased from several different sources and in small quantities. Old: There have been many numbers thrown around for the Rotax starting required rpm. We don't have magnetos we have trigger coils. In order for these to get excited and fire current to the plugs we need a minimum of 225-250 engine rpm which translates to 92-103 rpm using our 2.43:1 gearbox ratio. Now if your battery is weak and you only get 85 prop rpm or less it won't start. You can not tell the difference looking at the prop or listening between the 93 to 85. So if your aircraft doesn't start you need to use a newer battery or jump it to rule out the possibility of a poor battery. We have 5 trigger coils. 4 for our needed amps/voltage and one for the tach signal. -------- Roger Lee Tucson, Az. Light Sport Repairman - Maintenance Rated Rotax Repair Center - Heavy Maint.
