Its funny, because now DA has dropped Amsoil and now recommends Redline.
Jody from Valleyview also recommends Redline and Stihl Ultra HP.
A lot of the big engine gurus have been dropping Amsoil and switching to Stihl Ultra HP.

Can't wait for the read ;)

Hey Don!! Thanks for the post - I forgot about our chat last year when you mentioned you had one also!!! I've got lots of questions for you now, so a PM will follow. :):)

Thanks for the primer detai vs fuel pump - more to be discusses for sure!!

I've been reading the same about props. Seems a static RPM of ~4900rpms is where one wants to be (so that max RPM does not surpass 5500...dependant on plane also) and many like the Xoar or Menz (both in the 26x16). I'm also reading that many like the Menz 28x14 and 29x12 for that same rpm consideration along with the 25x14 3-blade.

Rumor has it, these radials are very dirty on 32:1 Yamalube, so I was going to go 50:1 amsoil as per your post and many others!

Still having trouble getting details on what sized tank I need for the Moki150? - seems a 600mL tank will be more than enough for 14 minutes, but will need to check wih you.

Cheers

Trev

Trev,

600ml is an awfully small tank!
but these engines are fuel misers- I've got a 32 oz tank in the Boomerang and it'll go 18-20 minutes no problem. I'm running it full throttle probably 80% of the flight too.
Intake and exhaust (especially exh) tube nuts come loose for the first 10 flights and need a gentle tightening on a schedule.
Valve lash is pretty constant, I've had to tighten them up probably 4 or 5 times.
I agree with Jack regarding oils, but add in that cooling is critically important- if an engine is not cooling well, every type of oil will carbon up.

I agree with Jack though - I think it all comes down to personal preference and likely doesn't matter what we use as long as it's tuned properly. In reality, there's nothing very high-tech about our motors - they're pretty basic motors like a chainsaw or lawnmower!!!

Still... Amsoil all the way, LOL!!! :):):):)
