HI Nelson,
Thanks for the advice I already tried the new setting and found not much changed from the previous one as far as yaw is concerned. The 701 seems to accelerate much faster now and the engine doesn't revolution as much and the prop doesn't wine that much anymore. All in all, I'm pleased !
Norm
You're right ! It's a lot of thrust ! And I will post a video to boot. Stay tuned. We still have to see if the engine was revving too high. If so, we'll repitch the propeller 0.5 degree more and try again. Trial and error.
you are right. It is a Subaru EA-81 that originaly was rated at 73hp. It was reworked (porting, head work, timing...) and was tested at 105hp on a dynometer.
Thanks for the 'Husky' comment...The owner of the hangar called me today and told me he coudn't believe how a coat of paint and some trim could change my plane so much. Me neither for that matter.
Gidday Nelson. re yr comment about cowl layup. I cut 6 thin MDF profiles and a round piece the size of the spinner plate & taped them to the firewall at the rear & prop hub mount to give me a guide to the shape I wanted. I then scrunched up news paper and stuffed it around the motor/gearbox etc to fill most spaces, then taped 1" styrofoam sheet between the MDF profiles to roughly fill the remaining space. Then the fun part, squirt expanding (plumbers) foam in to fill the remaining gaps which also acts as a glue to the MDF & styro to hold it all together. Use breadknife & surform rasp to roughly shape. Then add more foam in any holes and do it again until you get the desired shape. Be sure to mask any areas you don't want stuck with foam and don't leave gaps where the foam can enter to stick to the engine exhaust etc. Lastly cut the top part along the line that will make a top & bottom part and prize it off. That's where I'm up to. I am going to use plaster of paris to smooth over the foam and then spray this with auto body putty to give a smoother surface, then spray paint with auto paint and finally give it to a fibreglass shop to spray on release agent and chopped strand mat to make a female mold. Then it's back to me again to lay up a fibreglass cloth cowl in this mold, make a join line joggle etc for Dzus (or whatever) fasteners and thats it. Well thats the plan anyway........................ I will take pix of separated cowls and post on my site later today. Hope all this helps. Cheers, Ian
Hi we are away working won't be back for 2weeks
I will try to send some pic when we get back

I have a list. It is only a list of all the parts though. Not everything is stated as to what it is made out of. You too can get this list off the Zenith web site.
Nope, the engine sitiing in my CH701 is an EA-81 1800cc 73hp in its stock version.
Mine has been reworked and is supposed to develop 105hp. We'll see about that soon enough. It is lighter than the EJ-22 /25 or even the EA-82 and less complicated.
Thanks for the comment on the instrument panel...Just got to be careful and plan ahead...Now That I think of it, I don't know if I wouldn't replace it with a glass cockpit ???
Welcome to the club!! You might want to talk to John Rizzo, he lives in Oley and is scratch building a 701. I have not talked to him but I believe he is almost finished building his 701. I'm retired and started building in January. I have the tail (rudder), elevator, most of the wings, rear fuselage and part of the foward fuselage completed. Hurt my back a few weeks ago so not much getting done lately. Hope to have everything finished and ready for final asasembly less engine and interior by the end of next month. Have to get hold of John, I'm sure I'll need some help for the final assembly. Need any help/advice let me know. Have fun
Yep, Now you know why I needed the twin sticks instead of the middle stick. I needed the space and the center console for the throttle quadrant, radio and some other switches. It was either that or twin controls on the instrument panel. I liked this arrangement better.
Brake handle on stick is for the Amphibious float brake system. It is old school drum brakes in the floats main wheels. It was put on the passenger side stick only temporarely. Goes on pilot side when on floats.
Thanks, Nelson. Yeah, I've got the DVDs, they're pretty good. But in this particular case, the assembly manual was actually more helpful than the DVD. Anyway, got it fitted perfectly, front fuse attached, no problem.

Keep building...It'll eventually fly !

Hi Nelson,
Hard to say but getting closer...Carburator tests over the weekend, adjustments and then Taxi tests. Before year-end for sure !
Cheers.

Hi Nelson,
Thanks for your comments. I'll post a video as soon as it takesoff !

I see you're getting ready to do serious work !!
It's feasible ! Just keep at it !
