This is the servo setup as shown below looking rearward from front of fuselage. I'm using a 6 channel DX6i. I would like to know how to set up the ailerons / flaps so that I can use flaps attached to throttle to allow for controlled flap deployment when flying but then using flap switch on transmitter to apply full CROW for landings. So far I've got the flaps mixed to the elevator so that as flaps are deployed, then elevator up trim is applied. But when I use flap switch for CROW, each flap works in opposite direction!!!!!!!. How to solve this problem please?

Can you identify this slope soarer?

Making progress me thinks http://gb.trapletshop.com/howzat Certainly looks the part -

Sorry - no that's not the one -
2.20m two piece wing with full span ailerons. Have acquired this slope soarer that I’m trying to get back ready for spring Has 4 Futaba servos all wired in that drive rudder, elevator and ailerons / flaps. Picture right below shows the left servo driving the flap mechanism on aileron servo (just not visible behind central rudder servo). Aileron are driven by short pushrods that exist fuselage just below the wing / fuselage junction and have snap on connectors Model has central wheel

Hi All Thanks for the feedback. I am feeling a bit more confident that the recommended CG is OK based on what you both say. I was also worried that I may have over loaded with lead but think I should also be OK. Reason for this being that in the threads you mention you put in 11oz, but right up in the nose. And then later on added 30gms to get it perfect. So overall thats about 12.5 oz. In my case, the weights are slighty further back in the section between nose and first bulkhead. And I've just weighed it and can see I've put in 13 oz. So all in all we're in the same ball park. With the CG as per instructions and with 13 oz in slightly more rearward to what you have, it balances just slighly nose down. So am now going to power on towards first flight . . . . . Frank Any idea how much weight you added so we can get a comparison? Regards Martin -

Hi Just watched the video & very nice. I am just in the process of completing mine but I have a balancing question. Did you find that with the balance point at 6.5 cm from LE was correct? And if it was, how much lead did you need to add? I've got mine balanced as per instructions but I'm thinking that (based on a centre section root chord = 22 cm that 6.5 cm = 30% as stated) is too far forward and am worried that the balance point is wrong. Should maybe be a little further back at 40% (8.8.cm from LE). Flew a Stargaze 2 at the weekend and had exactly this problem. Built as per instructions and balance point but when flying was to nose heavy and always have to use up elevator to correct so was not flying at its best. Now I've spotted someone from the Guisborough MAC saying the instructions are wrong and this was pointed out in RCME 4 / 5 years ago. -
Hi Does anybody have a copy of plans for the WOT 4 ARTF as I'm interested in building 1 from scratch on a shoe string. I had a WOT 4 ARTF that was brilliant with an SC61 but a nasty stall too near the ground finished it off . But the wing halves are OK and if I had a copy of the wing plans I think I could rebuild. Look forward to hearing. Cheers Martin

Had planned to out a OS46 LA in. Put I have an SC61 spare. Obviously heavier but has anybody else out in an and flown & engine with this size ???

Hi Cause of a recent crash (very poor aileron control in air) now points at a faulty aileron transmitter stick. How to describe the fault though! Rather than being pingy responsive (move it over to one side & it should ping back to centre - like twangying a ruler on a desk) ) it mushes back. Had the back off - but can't see anything obvious that is causing stick to mush rather than ping. Anybody got any ideas re a repair?? MArtin

Hi All Hope you can help. Basically with the barrel closed the engine will not stop running. I've adjusted the low running needle but it will not stop running - just idly ticking over. Attached is an image that hopefully illistrates the problem. With the barrel almost closed (as looking down on it from the front) a gap appears in the top right hand side which is the groove that controls the opening / closing of the barrel. Anybody got any ideas?
