Thanks everyone... I have never had to touch the low speed wheel on ANY of the Moki's.. I just never considered it. I will try later today. BTW, Although the 5 gallons may seem a bit excessive, there wasn't much flying going on over the winter, so I ran it as often as I could for the breakin.. I was just trying to be thorough in my description. We usually run about 2 gallons thru the new motors before a maden flight, but this one was an exception. Thanks again.. Will let you know the results.
