Nothing in the C-1 states any weight restrictions, there are some in the below OI (available on E-pubs).
Per the 11-2A/OA-10, A/OA-10--Operations Procedures:
3.22.3. Landing Restrictions:
3.22.3.1. When the computed landing roll exceeds 80 percent of the available runway, land at an alternate if possible.
3.22.3.2. When the RCR at the base of intended landing is less than 12 (unless specified otherwise by MAJCOM, AFRC or ANG), land at an alternate if possible.
3.22.3.3. Minimum landing RCR is 12. Per MAJCOM guidance, OG/CC may waive the minimum RCR, for specified units operating in cold weather locations, but in no case will landing be attempted with an RCR below 8.
3.22.3.3.1. (PACAF) 354 OG/CC may waive the minimum RCR for landing to 8. When the RCR is less than 12 and the crosswind component exceeds the RCR, landings are prohibited.
3.22.3.4. Do not land over any raised web barrier (e.g., MA-1A, 61QS11).
3.22.4. Normally all aircraft will land in the center of the runway and clear to the turnoff side of the runway when speed/conditions permit, unless local conditions dictate otherwise.
3.23. Overhead Traffic Patterns:
3.23.1. Altitude and airspeed will be IAW T.O. 1A-10A-1 or as directed locally.
3.23.2. Overhead patterns may be flown with unexpended practice ordnance, night illumination flares, 30 mm, unexpended live air-to-air and forward firing ordnance.
3.23.3. Initiate the break over the touchdown point or as directed.
3.23.4. Execute the break individually in a level 180 degree turn to the downwind leg at minimum intervals of 5 seconds (except IP/SEFE chase or when in tactical formation).
3.23.5. Aircraft will be wings level on final at approximately 300 feet AGL and 1 mile from the planned touchdown point.
3.24. Tactical Overhead Traffic Patterns:
3.24.1. Tactical entry to the overhead traffic pattern is permitted if the following conditions are met:
3.24.1.1. Use published overhead pattern altitude and airspeed.
3.24.1.2. Locally develop and coordinate with appropriate air traffic control agencies specific procedures.
3.24.1.3. Four aircraft are the maximum permitted. Aircraft/elements more than 6,000 feet in trail are considered a separate flight.
3.24.1.4. Normally position wingmen opposite the direction of the break.
3.24.1.5. Regardless of the formation flown, no aircraft should be offset from the runway in the direction of the break; the intent is to avoid requiring a tighter than normal turn to arrive on normal downwind.
3.24.1.6. Fly normal downwind and base position.
