I will most likely regret stepping in this steaming pile.
They are NOT a superior motor. They MAY BE a superior FK style motor however. Time will tell.
I understand the frustration of those who have spent years and big $$ chasing a primo PD motor. Although Retro was based on taking the motor out of the equation we all know that was more fantasy than fact. It just can't be done.
Now, looking backward you have spent a lot of bucks getting your motor program to where it is today. Try looking forward. If, and it is IF because the RH is still unproven for the most part, the RH is as good as appears then think of the money you won't need to spend. Now, when you buy your PDs, and they are duds you send them off to be refurbed in the hopes that they come back faster. After a $70+ investment each you still may have a dog. With the RH you are out $13. That is a BIG difference. All the complaining about supposedly poor refurb jobs and not getting back what you sent in... OUT THE WINDOW. Eighty-one percent more $$$ to spend on other things. Since it isn't a dominant motor your good PDs are still good PDs. See any negatives yet?
I don't know where the money-grubbing comments come from. As a track owner I make less margin $$ off a less expensive motor. And if it proves to be a better FK then I will not be selling as many F7 or TSR motors. But, it might make up for that by increased number of racers who couldn't, or wouldn't, shell out the $50 for a PD.
