Hello all. A buddy and I are assembling a Hobbico Avistar 40. I read about some of the mods to improve the aerobatics and better landing abilities. My question is what is a good engine to put in it? I want something with power - but not too big so that its extremely nose heavy. I was considering a 50 size or bigger.
ANy thoughts? I see some models claim the same size/weight as a 40 but with power of a 60 (or something).
The 40LA is weak... what is your experience?
Thanks!
Hello Sir!
My experience?
Ok,
the Avistar 40 ARF was my 1st and for sure most loved airplane i've ever had.
We all have sth to love most,right?
If i recall correctly,
i have bought it 5 years ago,
when i was a student by that time...
And immediately after my purchase ,
i started saving again,
for an OS engine.
I knew that it was going to be an OS LA series, cheap,trust worthy,easy to start/fly/maintain.
Eventually after 3~4 months i bought an OS 46LA.
Man,
that engine....never ever quit on me.
I don't even know what i did so good,
but that engine worked every time,during day,during night,hot wetaher,cold weather,0% nitro-15% nitro,full throttle until fuel tank empties.
Whatever you wish to,this engine was capable to do (ofcourse,LA's are not ringed...so not powerful to compete with ringed engines)
But for an Avistar the OS 46LA ,for me, worked excellent.
I believe though,
that because you mentioned the OS 40LA,well, that's going to be underpowered.
I also installed std size servos ,Futaba S3003 and S3004.Realtively cheap i guess.
Mmmm,
what else.
And for the engine i always worked it with APC 11x6.
If you want to ask sth more ,post it here!

PS.
I am so angry with myself for selling the Avistar after 3 years of continous flying...but you know...when you're a student you must sell sth,save some money and then buy sth more expensive (...and better flying/capable of course)
