BILL PETTIT Posted May 25, 2011 Author Share Posted May 25, 2011 Yea Doug: I did one build where I glued all the parts together then tried to cover it, NOT AN EASY TASK!!. Never did that again. Well after installing all the servoes pushrods and tailwheel and all the nose weight to balance it out the total all up weight of my WEBbit was real close to 3lb.s. I build them heavy,Maiden tomorrow if the weather holds. Bill Quote Link to comment Share on other sites More sharing options...

Big Bandit Posted May 26, 2011 Share Posted May 26, 2011 Hi Bill, Certainly looks a very good model and it's a pity you can't maiden it, but not in those winds looking forward to hear how it fly's. Cheers, Chris. Quote Link to comment Share on other sites More sharing options...
David Gilder Posted May 27, 2011 Share Posted May 27, 2011 I'm in the same boat Bill No maiden for me yet as the wind here by the Penines is blowing 15+ mph all the time!! Must maiden before Greenacres though or it wont be allowed to fly there!!!! Dave Quote Link to comment Share on other sites More sharing options...
BILL PETTIT Posted May 28, 2011 Author Share Posted May 28, 2011 A very nice day today so we went for it and I am pleased to say I had a successful maiden. I need to do some tweaking on somethings C/G is the big factor and wing incidence is another. Radio adjustments adding expo and end point adjustment helped and I had fun with it,sorry no video had my hands full so after a long wait all went well.

Big Bandit Posted May 28, 2011 Share Posted May 28, 2011 Bill, I didn't have any doubts that it would fly well, very well done mate. how was the power train !. Cheers, Chris. Quote Link to comment Share on other sites More sharing options...
BILL PETTIT Posted May 29, 2011 Author Share Posted May 29, 2011 Chris: Very strong power train, unlimited vertical I think I will try to extend the motor more forward to aid in C/G. and maybe a bigger prop with a heavy prop nut. Rich I wish I could be there for the RCM&E Fly-in. What is the date for that so I can do a long distance honorary flight.Thanks to all that posted while I was building kinda keeps you going and motivated to finish on time.

Chris Bott - Moderator Posted May 29, 2011 Share Posted May 29, 2011 I'd be a little careful with a bigger prop Bill, it will increase power, and increase current draw. So it could be too much for the motor, the ESC or the battery.. Don't want to let any of the magic smoke out! Quote Link to comment Share on other sites More sharing options...
Biggles' Elder Brother - Moderator Posted May 29, 2011 Share Posted May 29, 2011 Hi Bill, glad to hear it went well. Greenacres fly-in is 25th -26th June - we know you'll be there "in spirit" and we'll raise a glass to your WebBit under "absent friends"! Its certainly not WebBit maidening weather over here - we've had high winds for 4 weeks now - the whole of May has been wash out. Still the slope soaring guys like it!

BILL PETTIT Posted June 1, 2011 Author Share Posted June 1, 2011 A question ??? I have flown the Webbit only 3 times once in the air I have good control and flight characteristics are predictable, My problem is take offs It is a very long and fast roll before she takes to the air and at that point it is very abrupt and steep and I have to be right on top of the sticks to recover from a stall. Any ideas about this? Thanks guys Bill Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted June 1, 2011 Share Posted June 1, 2011 Possibly tail heavy? Perhaps she's sticking to the ground, and then when up, a bit pitchy causing the drama?The other thing you might try is some expo on the elevator Quote Link to comment Share on other sites More sharing options...
Richard Harris Posted June 1, 2011 Share Posted June 1, 2011 Bill, Are you using enough rubber bands to secure the wing on? I was thinking maybe the wing was lifting off the seat at the LE? Mine is pretty fast on the ground due to its size, but if the tail is lifting as it picks up speed it should just ROG OK. Do you have a video of it doing it? Rich Quote Link to comment Share on other sites More sharing options...
BILL PETTIT Posted June 1, 2011 Author Share Posted June 1, 2011 Rich I use about 8 good rubber bands and also I have added a wing centering pin,with both I have a good tight fit. Tim I did put in some expo 30%in, I may need more, the weight in the tail may have something to do with it I have added a lot of nose weight to get it to balance out may need even more but don't have any space left. Do they make heavy prop hub/ nuts for these motors? I cut in some vents in the underside of the fuselage just aft of the wing mount to help in cooling. Weather not good today to do a video but will try soon,(weather permitting),Don't know about you guys but it is the start of pollen season over here I have a huge poplar tree that turns my yard white and an inch deep with little fuzzies for the lack of a better term and they float in the air for ever, UP YOUR NOSE in your eyes you get the picture. Keep in touch Bill Quote Link to comment Share on other sites More sharing options...
Chris Bott - Moderator Posted June 1, 2011 Share Posted June 1, 2011 Bill maybe when sat on the wheels, your wings angle of attack is too low? Can you get the U/C higher or the tail lower at all? Quote Link to comment Share on other sites More sharing options...
BILL PETTIT Posted June 1, 2011 Author Share Posted June 1, 2011 Chris : next time out I will pinch the Landing gear together so it raises the front as much as possible. Thanks Bill Quote Link to comment Share on other sites More sharing options...

Big Bandit Posted June 2, 2011 Share Posted June 2, 2011 Hi Bill, well done mate that looks a bit of a handful in pitch, how much throw have you got on the elevator. and where does the Cof G come. Cheers, Chris. Quote Link to comment Share on other sites More sharing options...
Richard Harris Posted June 2, 2011 Share Posted June 2, 2011 Hi Bill, Nice flight, looks to me like you need some nose weight in for sure as it was certainly pitch sensitive. The second time you took off it seemed as though there was some sort of of rudder trim added as it looked to be yawing. When you had landed it looked to me as if you tried to straighten out the rudder? perhaps you need the 'original' rudder trim? You also mentioned that right turn was not as effective as left? maybe worth while adding a touch of right thrust to the motor? I don't no whether it will work or not but remember how we hang the gyros to set the thrust line up, could this be done to see if the prop torque is swinging it round? This way we could set up the right thrust before ever leaving the ground. Enjoyed that! Rich Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted June 2, 2011 Share Posted June 2, 2011 Yup, looked pitchy to me too. Quote Link to comment Share on other sites More sharing options...
