I was wondering if the rods are interchangeable. The LA rod has bushings at both ends while the FP has it on the large end or in my FP it has worn out. I posted this question on Stuka Stunt in which a rod was located but no one could answer the question. The one problem with the rod that was located was the shipping involved which was almost the cost of the rod itself. In any event it would be nice to find the answer as Tower Hobbies has the LA rods in stock. I don't have an LA to compare them side by side. I also don't have the proper equipment to measure the actual rod length so a side by side comparison would be in order here. If anyone could help here it would be appreciated. Ken
