I have seen several photos and videos of 701's with an A-65 engine. I am getting near completion on my 701 and have access to an A-65 with two hours SMOH. Does anyone have knowledge of what sort of performance this combination would have? Also, any ideas for a motor mount? Any info would help. Thanks.
I don't have any direct knowledge of this combination but there have been a lot of good, successful airplanes that have flown behind this engine. It wouldn't win any STOL contests, but it will get you in the air. Depends on your expectations and if its a good deal.
Thanks for your note. Aside from getting a great deal on the engine, I am a bit older than most on here, so my "need for speed" has diminished over the years. Low and slow will be just fine. Thanks again.
Henry it's your choice. I was flying behind a Jab 2200 (80 hp) I wasn't happy. The 701 is a draggy slow aircraft. not known for speed. Your age has nothing to do with it. put a 912uls and enjoy true low and slow flight. The extra hp will be useful when the ground sneaks up on you when going a little to slow. I took a ride in a 701 with a 582. I will never do that again. with the extra hp you will be able to give a grandchild or friend a ride and never have to worry that the engine will get you off the ground.
A lot of 701’s with a heavy engine folds their front gear. It’s not designed for that much weight up front. That leads to a prop strike, cowling damage, new prop,new engine, new firewall...is it worth it?
Here is a talk from first hand flyer of a CH-701 with A-65. Very stock with a exception of 'NO SLATS'. This gave me additional 6-8 mph cruise without affecting any other flight phase performance. (Yes, it does't do the 'hanging by the prop' show off but performance overall is quite satisfactory). I do have a second 701 with Rotax 912 UL so the comparison is very practical and first hand. here is a recent video of formation take off:
Performance: Cruise all day at 80MPH @ 2100RPM burning 3.5 GPH. Dual climb is about 700 fpm @65MPH and solo I can do over 1000 fpm. Will not climb like a typical STOL 701 but do climb much better than a Cessna 150/152.
No offence to anyone but I have to disagree with some of the comments. The total weight difference of 912 with all fluids and accessories is about 22lbs less than a A-65. When Zenith used to sell mounts for this engine and provide support then how can we say that the plane was not designed for this powerplant? On the other comment, I have seen multiple nose collapses on 701 ( and other planes) with rotax and even BMW engine and I don't think the blame is on design or weight of the engine in those cases.
Keeping in mind that I do have an aircraft with 912 (so no bias), I would prefer flying behind a continental any day because of their simplicity, ease of maintenance, availability of parts, proven and rugged technology and technical experience available.
Hope this helps you make a educated decision.

PS: I just picked up a CH-601HD project and am considering putting a O-200 in it.
