| Subject: | AA5 - Performance Modifications |
I fly a '74 Grumman Traveler and recently had a top high compression
overhaul completed along with a Powerflow exhaust. I am looking for
additional performance enhancements for speed climb and endurance.
A few days ago I initiated a conversation about winglets but it seems
too complex, costly for too little performance.
I am looking into wheel pants but am concerned about the cost of
installation and product, so far I have ony investigated DMA.
Is there anything else?

Hi Andrew
If you want the most bang for the buck you'll spend less and go faster just s
elling the Travelor and buying a Tiger.
If you want to make the Travelor go really fast the most bang for buck is t
hru Maynard Crosbys STC for installing a
180HP Lycoming up front. There are a few Travelors with this engine and thei
r owners like to think they are faster than
Tigers. Maynards number is (425) 493-7067. You can clean polish wax drag red
uce prop change aft CG and lighten until
You run out of ideas but all that combined won't give you as much gain as th
e bigger engine. Do all that and add the engine
and then you'll have the fastest Travelor

I am compelled to agree with Ned. Sell the plane, get a Tiger. Absolutley
the cheapest way to go faster. Everthing else is an experiment in how much
money you can spend in a never ending pursuit of "almost as fast as a Tiger"
for far more money.

to it, as well. You're just starting from a faster basic aircraft.

Some place in my archives I have a rather complete 337 for the use of
DMA AA1 Wheel Pants on an AA5. Since I got it through the New England
FSDO - it must have been good enough. If it is needed, let me know - I
will do the archeology and find it.

HI Ned,
I tried selling mine and buying a Tiger, but I would not have received
much money in return to offset the cost differential. So I decided to
do engine mods. I might try what you are suggesting again but more
likely I will get even less of the money back. Thanks.

Barry,
Is the idea to twist it to get a bigger bite or a finer bite? The issue
I have is I fly out of a fairly short field so I need a bit of climb
performance.

Depending on your level of risk aversion, get the Sensenich prop for the Hi
gh Compression O320, pitch it to 63-62-61. -200 fpm better climb and 2 kn
ots faster than the stock 61 inch pitch prop.=0A=0A=0A_____________________

Andrew:
A lot more info is needed to make that judgement/call:
- How long a runway
- Type of runway
- MSL of runway
- Prevailing winds to runway
- Density ALT
- How much does the plane weigh for your flights
- Alt required to clear any obstruction(s)
- What is your Max Static RPM
- What pitch do you have now
Answer these questions and a calculated judgement can be made.
