I suppose I know the answer to this question, but I really like the Venus II and haven't found a suitable airplane for my OS 75AX. Do you folks think this airplane would be too underpowered with the 75? I am a sport flyer that is working on my pattern flying skills. I have just had my second US 60 self destruct. This time the ailerons buzzed and it ripped out a wing mounted servo. I loved the way the US 60 flew but the 75 was a bit much. Those are very powerfull little engines. If you guys do think that the VenusII would be too large for that 75AX, have you any suggestions? I guess I could use the .75AX and if I am not happy I would change to a 120AX.
I have not tried the 75AX on the venus, but i beleive it would be under powered. That might limit the wonderful potential this ship has to offer, never allowing you to experience the real Venus II in its glory. Remember it's a 90 size ship. OS now makes a 95AX as well, that might be a nice option for the Venus. As for the perfect engine, the 120 AX is it, abeit it is out of spec for that plane. I have proved to myself the airframe is ample strong enough to handle the 120 perfectly. With that said we cannot blame Great Planes for a failure in the airframe once you go out of spec.
As far as buzzing ailerons, i have seen some guys at the field with that problem. cheap servos caused this problem with lots of gear lash can do that amung other things. In my opinion dont spend less than $50 on servos for the Venus II. I spent $85 and would not change it for anything. Thousands of flights have proven that. A bunch of grumpy men have sneered at me for using pricey digital servos. This as they spend most of thier time at the field on the bench tinkering with old junk while I am enjoying flying. Not that price is the reason for successful servos, but usually its price that drives guys to put inferior servos into a plane. In the end they pay for it in a lost plane or at least inferior performance. Hitec digital Karbonite servos are made exactly for a plane the size and style of the Venus and suit it perfectly.
