Tim Mackey Posted February 10, 2010 Share Posted February 10, 2010 The only reason AH doesnt recommend ballast is because they break more easily on arrival - it will help the handling and penetration in strionger wind....but the added inertia can break the model on heavy landings.

Neil Sinclair Posted February 10, 2010 Share Posted February 10, 2010 Ross, I have got a Fusion 60 for Xmas which is as yet un flown, but have added ballast as per Peter aka Peewit's photo's in an earlier post on this thread. The good thing about ballast is you can always remove it if you need to. Neil Quote Link to comment Share on other sites More sharing options...
Peewhit Posted February 10, 2010 Author Share Posted February 10, 2010 Ross, Doesn't matter what it looks like. With 4oz ballast it will fly well in 12mph to 25mph, as opposed to flying poorly in 10 mph without any. It is very sensitive to elevator trim and one click of up or down makes a lot of difference, Neil, about time you maidened that fusion!

Peewhit Posted February 10, 2010 Author Share Posted February 10, 2010 ps have had to land it many times with a lot of down - literally dive into the ground - and apart from a crinkled nose, have not managed to break it yet. Quote Link to comment Share on other sites More sharing options...
Neil Sinclair Posted February 10, 2010 Share Posted February 10, 2010 Peter, Work has got in the way and the last few week ends the ice in the hills has dragged me away on my other hobby. I have been monitoring the wind for Friday through to Sunday but its predicted northerly which is perfect for Bosley Cloud but the wind speed is only 8 - 9mph. So fingers crossed wind speeds will increase. Quote Link to comment Share on other sites More sharing options...

Ross Pert Posted February 10, 2010 Share Posted February 10, 2010 Posted by Peewhit on 10/02/2010 20:51:47:Ross, It is very sensitive to elevator trim and one click of up or down makes a lot of difference, Neil, How much reflex (is that the correct term?) i.e elevon up to I set since it's so sensitive to elevator? It's not really dealt with in the instructions other than the darwing.I guess you have to adjust the mixing so elevator side of things is limited and controllable but the ailerons can give full travel to keep roll rates higher. Or just use massive expo on elevator??I won't get a chance to build this for a while but considering the scottish weather just now it's no biggy, grumble.

Peewhit Posted February 10, 2010 Author Share Posted February 10, 2010 The Yorkshire weather is no better Ross. The elevator travel does need to be limited as opposed to the ailerons which need to be "full". It depends upon which Tx you have. I use a Spektrum DX7, and you need to limit the aileron throws using the dual rate function. What Tx do you have? Quote Link to comment Share on other sites More sharing options...
Andy Freeman Posted February 10, 2010 Share Posted February 10, 2010 Reluctant to post anything other than a question of the sloping section these days in case i fall foul of one the RCM&E columnist rants. But as i do have a fusion 46 and found the control surface movements in the instructions a good starting point I would say you might do worse than following those to begin with. For me, those movements, were fine to begin with but I think i have a bit more aileron and a good bit less elevator now. Caveats: I am not the most skilled stick twiddler, I have only been sloping 2 years, my fusion is a bit heavy than recommended at 31 oz and seemingly you should never take advise from an internet forum.Although with out this forum I would have been stuck many, many times........

I don't think it will be dual rates that will limit the elevator though, it must be in there under one of the mixes to restrict elevator but keep aileron throws full when together. I'll worry iabout it when I get there. Like I said, won't get to build this soon, off to Val D'isere, different kind of sloping! Quote Link to comment Share on other sites More sharing options...

I think you are going to be looking for "end point adjust" to tame the elevator down. Thats what its called on my Futaba T9CP anyway. I think its a fair bet its called the same on your set. Hopefully someone with the same set can confirm this. Quote Link to comment Share on other sites More sharing options...
Peewhit Posted February 12, 2010 Author Share Posted February 12, 2010 Yes, end point adjustment will reduce the servo throws yet it will also reduce the aileron throw as well as the elevator. What is needed is full throw for aileron and reduced throw for elevator. On the 6EX, activate elevon mixing and use the %age settings in this program to set the correct aileron movement. Then use the elevator dual rate settings to reduce the throw for elevator only. I would suggest setting both dual rates to the same %age so that the dual rate switch then does not change the throw.

Neil Sinclair Posted February 15, 2010 Share Posted February 15, 2010 The Fusion 60 is still sitting here waiting for its maiden and after the discussion on elevon throws I thought I would check mine this evening. I have a 6EXA and the method from Peewhit worked a treat to make some minor amendments. Checked the weight to and it comes out at a heavy 1000g rather than the 800g from the plan. I have the ability to add another 100g if needed in a real blow. From the discussion earlier it seems that 900g is optimum. Is 1000g to heavy ? Have attached a pic of the heavy beast.......wish wind and weekend would coincide !!!!!
