RPM limit change for SSC plane flown in Limited B

Post by lightning »

I have been asked to submit a rules change proposal in an attempt to level the playing field a little for those pilots who wish to try Limited B using their SSC planes (which is allowed in the current rules)
It has been suggested that enforcing a 17,500 rpm limit (per current SSC rules) puts these pilots at an unnecessary disadvantage when most 15s are capable of at least 18,500 rpms.
So the proposal is to allow otherwise legal SSC planes to run at 18,500 rpms when flying in a Limited B contest.

And while we are at it, should a change to allow 18,500 rpms in SSC at altitudes above 4000' be considered to make the class flyable at these higher altitudes.

Any comments/suggestions/opposition before I draft the full rules change proposal??

This was discussed at our last contest and consensus was to approve these exact changes. Thanks Kieth!

Who is pushing for the high altitude rpm adjustment? I will admit I have not flown much in the last 4-5 years but last I flew in Denver at 5000'+ our SSC ships did just fine at 17500. Yes, they do fly differently at high altitude but I don't know if more rpm is needed. I would encourage more discussion on the pros and cons of allowing an rpm increase at altitude.

Is 1000 extra rpms enough? Some of these little engines will pinch upwards of 19k. What if you just let um run?

Hmmm, not a whole helluva lot of support for this so far; even some opposition.
Based on comments received I will hold off on the proposal until it has more support.

Gentlemen,
I asked Keith to propose the rules change to keep the rpm consistant with 2948 scale. The speeds would be more equal but still limited with the bigger displacment engines. I don't think unlimited speed on one is a fair way to go, especially if you figure electrics into the mix. It was my thought that the high altitude might also require some relief so why not add that while making the change and kill two birds with one stone. If the high altitude part is not needed, then drop that part. The SSC legal to fly in Limited B rule was to heip guys make the transition to B class planes and more rounds of combat if they were at a meet that offered both when they only had SSC ships. They are at an added disadvantage if flying slower than the Limited B planes. They already would suffer from smaller thrust and greater damage in a mid-air. I would like to see more input on this matter before dropping it and starting over in another year or two. By the way, an SSC ship can fly in open B at any rpm, nitro or electric.

Definitely NO to unlimited rpm in Limited B. It is a limited class.

I think we should try out 18,500 for SSC ships in Limited B next year via a waiver. You don't want to make changes without knowing how it's going to work. For testing purposes, I'd fly SSC in Limited B to see if 18,500 is on the same level.

As for the high elevation proposal, SSC is now an AMA event and any changes should go through their rule change process, not ours.
