Looks good Randy, my soob mount had the same problem with the downward thrust, never did get it flying straight always had that tail low attitude and always needed back pressure on the stick. It will feel like a different plain for sure now that you corrected the thrust line like Leni says
The weight is 755 Lbs, I cant remember what my cg was but you were right about it being forward, I finally added 10 lbs of weight to the tail wheel bolts today and it made a huge difference, pretty much can let go of the stick and it flys pretty well level and the deploying the flaps is quite a but less nose down now as well. Thanks again Chris for the advice
Chris,It will be interesting to see how you make out on the stiffeners, I can only deploy the flaperons about 1/2 of the full travel ,otherwise I run out of elevator,I haven't notice any binding with that amount. I have the model C elevator so hopefully next project will be enlarging it with trim tab. I had the plane loaded with 26 gal of fuel and 2 people and didn't notice any extra binding so far
Hi Randy , no problems at all with wing flex and the flaperons. The only problem I have with the flaperons is them freezing up when water seeps into the hinge area. I throw on some lock de-icer and then some silcone lubricant and it solves the problem. I think a person could extrend a really long recipricating saw blade to cut the old one out but with all the rivet in the spars not sure how I could get the new one in. Do you know if the old inserts were usually epoxied in place or just a tight fit?
Im sure its to late to removing existing plywood wing inserts and replace with a longer one now that the wings are cover and painted. .I am wishing I had done this when I did my wing extensions but never thought about it. Did think about extending the struts but wasn't sure about having all the rivet holes from the old location in the spar so in the end just left it alone ,
Hi Randy, Willy is off on his heli ski guiding adventure for another week or so, he has got a few more hours on his bush caddy and seems to have all the bugs worked out.He is looking for a bit bigger prop to get a little more cruise out of it but other than that we should be getting a lot more ski flying in ,got a huge amount of snow this year
At -20c my RX1 engine couldn't seem to spin over fast enough to fire once it warmed up to -12 or so it started no problem, I only seem to get the shake problem restarting the engine after it has been warmed up, usually a quick shot on the throttle gets it past the low idle shake and it runs smooth but a clutch would diffenently help on the cold starts
