Most of the rear setups are throttle on,y but you can put whatever you want the gib to have so long as you have a clear line of soght to add the linkage from the throttle arm in the back to rhe front and the same for the mixture and prop controls if added. Use google search and the key words rv4 rear and throttle then seltct the images tab to scroll through the results for some examples. There is no goid way i have seen to lockout the access in the back for kids or the like though...
