HS 6 Movement with One Ion Engine

I've got my Physics hat on and I'm trying to ballpark on if a single ion engine could move the HS 6 ship. Opinion: Yes. With space having negligibly nil resistance to a reaction engine, one ion engine should move the ship, albeit slowly. If a full compliment is 1 ADF, theoretically, we should get 1/3 ADF.   Jumping: With a single ion engine, void acceleration wouldn't feasibly be possible. At best, it'd take 3 times as long to gain acceleration. At worst, the reaction mass would only get the ship to 1/3 of that magic 1%C to the jump.  I lean toward the latter. Not to mention slowing down... It'd be like trying to stop a speeding semi-truck by leaning into it and bracing your feet into the ground. Thoughts?
normally Ion engines in the real world would get you accelerations of 1/10000 of a G. A Star frontier ADF is equal to 1 G, so the fact that they can get you a single g of acceleration is miracle.. As i see it the atomic drives and ion drives of SF Universe do not use standard Rocket Mechanics and Physics, as even the atomic rocket prolong 1 G acceleration is physically impossible. Since Tachyons exist in SF universe, it likely that both engines actually use these FLT particles to create a tachyon rockets Consider the central problem of rocketry: how can one burn fuel at a high enough exhaust velocity to provide reasonable thrust without an unreasonable expenditure of energy. This is the dilemma that plagues our space program, and the solutions we have developed are not very good. So let's consider a device that makes great quantities of E =0 tachyons and uses them as the infinite velocity exhaust of a "rocket". Within the constraints of the conservation laws of physics, we can make all the tachyons we want for free, provided we make them in neutrino-antineutrino pairs to conserve spin and lepton number. Momentum conservation is not a problem because we want and need the momentum kick derived from emitting the neutrino-antineutrino pair. This leaves us to deal with energy conservation The paradox here is that with a high-momentum exhaust of tachyons produced at no energy cost and beamed out the back of our space vehicle, the vehicle would seem to gain kinetic energy from nowhere, in violation of the law of conservation of energy. The solution to this paradox (as can be demonstrated by considering particle systems) is that the processes producing the tachyons must also consume enough internal energy to account for the kinetic energy gain of the system. Thus, a tachyon drive vehicle might be made to hover at no energy cost (antigravity!), but could only gain kinetic energy if a comparable amount of stored energy were supplied, from the atomic power plant or ion engine in the form of particles. Electrons or hydrogen ions from the ion engines are very low mass and energy, while the fragments from atomic fission are at least hundreds to thousand of time more massive . So the power output is what matters the Tachyon thrust amplifier of an Ion engine are very likely max out, so they are limited on the amount of real thrust they can provide, while an Atomic engines' Amplifiers very likely operating at a diminish power level to prevent the reactor from becoming unstable.    Adding Ion engines may not help as they are drawing on the ship electrical power ( remember they are not atomic reactors) So ship with out reactor would be limited in it power output and usage. 
Granted, it all boils up to a Scott Ruling, but, I posted this question on the SF Forum. Here is the link: <a href="http://sfus.starfrontiers.info/node/9396" rel="nofollow">http://sfus.starfrontiers.info/node/9396</a> I'm good either way, just trying to cover the bases on if we have stealthy options.
If you do the math, 1 ADF in StarFrontiers is roughly equivalent to 5.67G. &nbsp;However, most ships move around at 1G b/c it's much more comfortable and plenty fast. &nbsp;The only time ADF and MR usually matter is for emergencies. Void speed is a velocity requirement, not an acceleration requirement. &nbsp;So technically, a single ion engine should be able to get you to void speed. &nbsp;As the GM, I could rule that the full complement of engines are required, but I don't see any reason to do that. I think I've said before that the KH expansion wasn't well designed - but it's still fun, as long as you take it with a grain of salt.
