I will re-tune this Sunday at the field with a 22 x 8 on it and check the RPM, do you think the DL-50 can provide sufficient thrust for IMAAC aerobatics at 19 lb Wt.

Chad I dont think the local hobby supplier has that Optic switch in stock, however will try to find a carbon fiber tube for the tail plane that may help to reduce the nose wt. Thanks appreciate all the help.
