Throw some sprayers on it an you have a legitimate high speed aerial applicator.

All the space and payload is already taken up with jet fuel. If I recall the fuselage tank holds 1100 liters and each drop tank holds 150 liters, 390 gallons. That will keep the engine running for about an hour.

Thank you gentlemen.

to clarify:  as it happens, the 185 knot Rocket has no step.  I kinda figured it had to be drag--I'm thinking mostly of control rigging, or even an elevator trim setting that's having to overcompensate for forward CG.  That airplane should be fairly clean.  It has a 1 piece belly, and the panel has a 430W, a KX155, and a KT76 xponder, no ADF.  Maybe the antenna is still there...

Or maybe it's the way his fuel system is set up?  I figure at that 21gph setting he's running the recommended 100-150 ROP, but maybe not getting a clean burn and actually making the HP?

on the other side, the YouTube Rocket (N231AM, just looked again) is almost certainly running LOP at 15.9 gph.  I can't divine his CHTs from the JPI, but the legacy TIT guage is reading 1425. He's got a 530, a KNS 80, something else as a King Comm, and a newish looking Garmin Transponder.  Antennas should be about a wash between the two unless they have a bunch of un-removed stuff (I'm not enough of a GA guy to know if you can even leave that stuff on).

Point is, the faster guy is getting 210 at 65% power at FL180, he'll probably also get the book number of 195 KTAS at 12,000, which is plenty fast, still at the elegant ~16 gph--and those 10-15 knots are enough for me to want that airplane more than I'd want an Ovation (not trying to start anything with that--I can live with an Ovation if the differnce isn't big enough).

But the slower guy is getting pretty much an Ovation number on a ton of gas, and he's 18 KTAS slower than book at 12 k, so he llikely won't make 210 KTAS at 65% power, either.

The slower airplane is nicely priced, and I'm tempted--pending the approval of the aforementioned Ministries, which are not yet in danger of granting it--but suddenly wondering about this speed differential.

Any other ideas?

And to thrown in another one:  IF I were to buy one of these machines, are there Rocket CFIIs one can find to teach what needs to be learned???  And can one get some training in a Rocket from such a CFII before one goes to collect the airplane from its pre-buy?  I'm obviously not the first person to confront this problem so I'm guessing there's a simple solution I'm too dumb to have thought of!



If you come to AZ, I know a CFI who has access to a Rocket he routinely flies, and he has flown mine as well(which is also for sale).  He might do the training elsewhere also.  I am sure he would give you excellent instruction as needed for the Rocket.
