seanychen, The 525s are only .3 inch less depth then the 605s and the 605s miss by a long shot. They do not say home much is above and below the mounting tabs so hard to say if it will really fit. You have 7/8ths inch at back of servo bay and 1 inch at front.
Do you have these installed on a Sukhoi? If so I will be purchasing some of these. Thanks.
