After going to a lot of trouble to get the weight of my  Mustang down I'm running out of options to get my CG further forward.  The  only solution I can think of is taking off my B&C starter and re-installing  the original Prestolite starter which I guess weighs about 10-15lbs more than  the B&C.  Assuming it will fit in my cowling, are there any major  disadvantages (advantages?) in using the Prestolite.  Thanks.  Allan

    They're certainly a known quantity. Tho shalt

    not fly a tail-heavy airplane lest ye discover

    that you have but mere seconds to regret it.

    A guy has to do what a guy has to do.



    What airplane are you working with and what

    combination of installation decisions painted

    you into this corner?

A guy called Mark Landoll (405-392-3847 from Sport Aviation) used to sell a harmonic dampener that bolted to the crankshaft and weighed 15+lb. It might help with the cg issues and also make the engine run more smoothly? I believe a B&C starter is around 9lb lighter than a Prestolite, but the cg of a Prestolite is a couple of inches further aft.

Bob, it's a Mustang II.  The CG is within the allowable range as long as

I manage my fuel properly and don't carry any meaningful baggage.

However, I suspect the rear CG is making my handling on landing more

difficult. As for the combination of decisions .. I bought the plane as

a part completed project with wet wings (rather than a single forward

mounted fuel tank). I've relocated the battery to the firewall (using an

odyssey PC625 - I might be able to add a second battery there or maybe a

heavier one but really like the odyssey).  I have a CS prop (a fair bit

more weight forward).  The only thing I regret is making a slick and

very lightweight carbon fibre cowling whereas I could have made a much

cheaper and heavier fibreglass cowl:)

Pretty good idea, and he also sells a simple steel ring of about the 

same weight that's a lot less expensive than the damper (had one on my 

1st RV-4).



BTW, if you need a Prestolite, I think I've got one on the shelf. Email 

me off list & I'll try to come up with a price.

 I replaced a Delco starter (similar to Prestolite if not the same  thing) with a Sky-tec which really screwed up the W&B on my O-320/wood prop  RV-6A exactly as you describe.  After hearing many recommendations on the  RV-list and elsewhere over the years, I added a Landoll Ring (a little over  $100) to my ring gear to balance things back out, but will need to get  everything dynamically balanced before I know the full effects of the  Ring.
