Thanks for early look at the rules, as this has stopped me before I got too far. This one has me befuddled: Modified Production class
"Perimeter type frame engine cradle tubes must remain unmodified." But it says you can change the steering head angle (not in my plans), which would be cutting and welding on the spars. Also, earlier in the paragraph it says it's ok to remove or modify brackets. Soooo, can you take the various wire harness and bodywork brackets off the perimeter tubes (sharp little guys that stick out the sides)? I've also had to move the rear upper shock mount, to do the engine swap, but that appears to still be ok.
Can you add brackets or mounts onto the original unmodified spars? I'd rather weld my new engine mounts on direct, as opposed to running long tubes from another area, but I'll work around as necessary. It doesn't appear the we are trying to prevent engine swaps (same brand), but if new mounts can't be added...hmmm.
Thoughts? Talk to Van, Tom or Matt? I'll try an email.
Regards, JimL
