Sorry if this is already answered somewhere else, but my son was given 4 Titan 550 motors and was told that they should work fine if the brushes are replaced. Where can I find info on how to repair these motors? If we can get them working, they could be the answer to my need to scratch build a 4-engine bomber as a winter project.
I normally use brushless motors in my planes, but have shied away from building a multi-engine model (except for my GWS-38) due to the combined cost of 4 motors and the multiple ESCs to go with them. Any help would be greatly appreciated. Thanks!
