thanks for the responses. I am considering keeping it a 2 stroke. Deciding between a TT or Magnum... perhaps the OS
ANy pros/cons between these? I want this to be a kickaround zippy aerobatic trainer... that i wont get bored with-> but I want to have a buddy fly it for training too. I plan to beef up the gear some to give it better clearance incase I want to throw on a bigger prop.
Suggestions?@! What would you do to have a zippy, fun trainer that zooms by! But is still fairly tame for a rookie with a buddybox.
My grandson has two Avistar's; one trike and one taildragger. Beginners need a spare. (-: The taildragger has an OS .46AX; and the trike has a Magnum .46. Both haul the plane around with authority. I don't think any more power is needed with this plane; especially with a beginner. At full throttle, either engine will pull the plane faster than he needs to go; vertical performance is impressive with both. Any more power and it would be too easy to pull the wings off. He solo'ed yesterday; but the Avistar will still be a staple in his flying for a while yet.
Both the Magnum and the OS will do nicely; but you simply can't beat an OS 2 stroke. No trouble since the day it was installed new; never a deadstick; never a hiccough; just fuel and go. Beginners have enough to worry about, without adding in engine problems and adjustments.
An engine alone won't give you a "zippy aerobatic trainer". An OS .46 will certainly make it "zippy"; but anything beyond basic maneuvers will run the risk of leaving the wing behind. Some beefing up would be in order. Just my opinion from watching my grandson put hours on his planes. Thanks; Ernie P.
