Accurate Engine weights Data Submission

Soon we'll be adding a database with engine weights, thanks to the urging of Bill Pryor of Oregon. Please send us your accurate information. As an alternative to the form below, you may submit your data to rpmstat@rcfaq.com . We will include the information as quickly as possible. Thanks!

Note: Please enter all weights in ounces. For very large engines, lbs is ok, just make sure to indicate if you are using 4lb 8oz or 4.5lbs, which is the same weight.
