This should be big fun.Crist is there any way you can post a copy of the plans in "tiled" form so we can print straight on 8.5x11 paper?
I'll see what I can do.
hi all Cant wait till march to go and fly these in Produbice paul
Well, it's done except for the electrics. The motor should be here Monday. Monday evening is for finishing it completely. The airframe is all done. It weighs 105 grams as it sits without tip weight. I think I'm gonna hit 235 grams. I don't know if that will be too heavy or not. WE'll see. Maybe Igor could add some comments.I had to enlarge the elevator cut out in the rudder by about 1/8 inch. Everything else fit very well.Enjoy the pics.
I see new toy is born :-)))Yes the weigh coud be aproximately OK, we have it also somewhere over 200gRegarding your elevator - we do rudder as separate part, so it comes AFTER elevator, and it does not need any cuttingBTW did you use those large drillers? because those parts keeping wing seem to be without tension .. but may be it is not well visible on the picture
hmm ... now I see it is not very well visible, probably I had to post better pictures, but you can see it in post #19 (3rd picture) in that old thread:http://stunthanger.com/smf/index.php?topic=19265.0if it is not clear may be I can find better pictures somewhere in archive
Also when bench testing I noticed that the battery wires and JST connector was getting warm. I also ordered some EC2 connectors for the batteries. I also might go from 20awg to at least 18 ot 16awg when I install the EC2 connctors. I don't want any connectors that are getting warm.
The CF2822 1300Kv motor arrived today. with the mount and bullet connectors it weighs 49 grams!
only 2 notes:1/ NEVER let it run on bench ... it will burn :-))) 10" prop is over possibilities of that power train, it will unload in air, but static draw it too large .. if you want, then use smaller prop2/ NEVER use those toy connectros, they are rated max 5A and they will not only get hot, they also limit power, I saw in on my own eyes, friend of mine could not make it flying overhead, we did not know why, and then I found that the connector was hot after flight, we used 1.8 mm MPJ connectros and problem was solved :- )))
I have thinner, I think 0.14mm but rated to 9 kilo or something like that
HelloI broke a line of the same material (sufix 6lb/2.7Kg), This is the last model where I expected a line failure but take care.I suppose the line had a defect but I went back to thicker lines.
Igor,Can you post a picture of the box the lines came in? The lines I'm using are .14mm but only 6lb 2.7kg. I'd like to know what .14mm line is rated at 9kg.Thanks.
no, sorry, I got that mine 4 years ago :- )))))I just know that the number was unbelievable and I did pull test and it was clear that the number was oveestimated :- ))) ... or simply rated without know, but it was far far over srength of depron constructionI see I will need to go to fishing shop where I got it :- )))
Alberto,Thanks for the heads up. I did a pull test to failure and the lines held up way past 6lb 2.7kg. See my video in the post above. Also are you guys still using the HK 2205C-1400KV motor?Thanks.
We use that motor but our models are about 50 grams lighter.
Christ, that bellcrank does not look like our 4"
the size 4" is to limit the force necessary to deflect elevator, the line tension is VERY small and size of bellcrank can limit controlling overhead on when it fly vely slowwe do it from GF plates 0.6mm but I had it also from old CD ... it is very strong material :- )))
So flying :- )))))))But slow? I see it was QUICK :- ))))The down thrust is for tractor, it must be reversed (up thrust) for tractor. I think you have too long upper line, it seemes like you have permanently up handle. That could be reason.And I think it is tail heavy, at least it looks overcontrolled in corners.And do you think it glides like a brick? I do not think. I think it does not glide at all :- )))))))))))))))) ... it is airplane with vertical landing :- ))))))
