i probably will order Diablotin Top tomorrow, so i need to know what motor to put in it.

i think two main candidates are:

YS .90 4-cycle, *or
.72 irvine

some details of the model:

Span: 1550mm Drive: 8,5-15ccm
Length: 1670mm Profile: Fun fly
Weight: 2,7kg.


Area: 77dmē take-off weight: starting from 2,7kg.
Surface loading: 35gr./dmē with v-version


8.5ccm would be out of question, cause lack of power?
what do you recommend for this weight/span plane?
