I was wondering if you could post some more pics or send me some I have had the same idea that you had about putting a turboprop in a aerobatic plane?

Tom,

I know the thread is old and you probably have your answer on if you can use this plane, but I have one question for you. If you are flying a turbo prop and have succesfully flown it a few times then your skills should be in good shape. Getting an IMAC pilot to watch you and give you pointers is worth tons.

Now as far as the IMAC rules here is the states, the rule clearly says what is allowed, not what isn't allowed so if you read it as written then turbines in any form would not be allowed. Now do I agree with the rule, not really as there are some out there. Is there enough to warrant a rule change, that depends. Electrics were added once they got popular, but lets face it, a good precision setup is already 2.5K for a good 50cc up to 10K for a fully blown IMAC ship in the 40% or bigger range. Now add the cost of the turbine, well you can see where this is going.

Now if I were to CD a contest I would surely let him have at it in basic, the only real problem is getting everyone away fro mthe plane long enough to fly the sequence as it is surely gonna get oloads of attention. I know that is counter-productive to what IMAC is trying to accomplish by being consistent across all regions and maintaining the rules as written but in the basic class, it has long been considered to be the fly what you brought class and that's a good way to get people into it. Let's face it, guys that get into IMAC and start in basic either love it or hate it. Most people starting in basic usually stay with it if they had help getting ready. The ones that mostly go away, at least in my experience, are the ones that beleive they are too skilled to start in basic and jump into a higher class and find themselves way down the list in points and get frustrated.

So Tom, try to get some help in flying the sequence and getting the plane trimmed properly, like thrust angles, mixes and such. Doing all of that will make your first IMAC expereince much more enjoyable. If you feel you are not ready, go to a contest and watch, offer to scribe for the judges and ask questions. Most everyone I have ever met in every contest I have ever been to are more than willing to help you get going, even the top pilots.

Hi, BjamesJr,
Thanks for yor comments. I have found that just practicing for the Basic has improved my flying a lot. I am a typical (I think) rc pilot, in that I can take off and land without crashing. I can do most manouvers. The hard part is to do these manouvers in a sequence and in the part of the sky required for the judges. This is what I need to practice more and more. I am geting better at setting up the airplane so It is easier to fly. I have a good friend who flys pattern and IMAC and we have made arrangements to meet up in the future to have some practice.

The model is not flying at the moment due to a problem with the engine. As soon as it is fixed I will get at it again.

Regards

Dear Silent-AV8R,

I would have to agree with everyone else on the language and actual verbage used in the rules. It says the recip engines shall be allowed, it does not say only shall be allowed and it does not say turbines are not allowed. I know that is spliting hairs, but if a rule is what it is written, no matter what the intent. Turbines have a strong case in being allowed to fly based solely on that rule. If the rules committe only wanted piston engines for internal combustion, then they should say piston powered only, that elliminates rotary and turbine without question, turbines are continuos combustion and rotary engines have lobes not pistons, all the engines have combustion chambers. My ten cents worth, (use to be 2 cents, inflation and all, you know)


By the way, just saw the IMAC event in Hamilton Ohio, You guys ROCK!!!!! Great Pilots, Great planes, absolutely inspiring flying folks, just beautiful!!!!!!!!!!!!!!
