Thanks for the comments Kelly about your DF experience on the T-33. I have had a couple of BVM kits before on DF, and I am sure that they were no stronger than the P60. At the risk of repeating myself, my Reaction 54 is 21 lbs, and I fly it 90% of the time at several different grass strips. I guess, what I am looking for now is someone who actually has a P60 in their T-33, and can comment on the results off grass. My gut feeling tells me that this should work, but there is nothing like the real thing to confirm this thought.
