336/337
Iromero.
There is a good history lesson on the 337. Check out the Riley website.
The reason for the 337 successor was the speed on the 336 did not compete with other light twins hitting the market. The 310 was getting very good miles/gallon compared to the 336.
Advantages are;
1) insurance / hard to do a gear up on this one
2) maintenance, something to consider.
3) your mission. typical profice of distance. short hops?
4) cost of annuals. / lower
5) you can forget the "3 green" over threshold..
6) cheaper to buy (my opinion)
Down side
1) its a drag....
2) slower.
3) harder to sell. (personal opinion)
4) picks up more ice.
5) little more sluggish on the climb.
6) cooling ? heard mixed reports, however, do not think it is an issue.
7) I think there is a difference in Gross Weight (less). But you also have less weight due not having all the hydraulics.
8) less macho ......... <G>
Think the big consideration is your leg length and typical mission. The range (amount of fuel) is less than in post 74 337s. You can add aux tanks on the 336 along with horton or other stall kits.
Unless you are doing a lot of X country or long range flying, the 336 will give you the second engine safety and certainly will cut the cost/hr for insurance and maintenance. You offset this will a little more time in the cockpit and a little more time on the engines...
I think GMAS can give you some numbers on the maintenance side of things.
Always pick an aircraft based on what your needs are, not your emotions ............
my 2 cents.
