I have to agree with the lack of power from the LA series compared to the TT, but have a OS LA 46 and never in its 3 yr history had a deadstick landing.... But as in all things, some of us get unlucky
.... But if money is no object go for the TT 46 Pro. Have 2 and would love a third, only ran out of time to build more planes and money to buy more rc and servos.
Have a super tigre .90 ringed and that is a bas**** to break in [:'(] after that its a lovely engine.... After about 10 tanks I did what most people do on these engines, kept it full revs for a whole tank and smoked the whole neighbourhood..... After that its a beauty...
Thats why I said, want an easy life get TT or OS. Other engines have some other peculiarities which will bother you until you get used to it.
have fun,
