I mentioned about the 'crowd' behind us being abuzz about the Bix. Check this out. One of the newbs' Dad was with him in the prep area, & his Mom was sitting in their car. She got out, came over to them & started asking about the Bix....she thought it was just beautiful* & wants one! How's THAT for recruitin'? *(and I agree!) I didn't catch it at the time but heard later on the video what sounded like Mike tellin them to check Banana Hobby (they were on an iPhone looking for info)....too late for me to correct so no tellin' how THAT's gonna work out! |

Gliding hands free ??
Hi ...
Now and after I've lost a lot of weight and my Bixler with an FPV dummy weight is 1016 g (35.85 oz) , Wing loading is 12.84 oz/sq.ft It balances perfectly at 65 mm from leading edge ...almost on the spar The problem is that I cannot glide unpowered and hands free ... it tends to dive when I cut the throttle and maybe tip stall too .. I have to maintain a minimum amount of throttle for it to glide .. I wonder if this is normal for my relatively heavy Bixler ... Thanks a lot Khaled |

Did you ever fly it bone stock to check it out? Might be a good idea to get it working right that way first. Although 60mm is the suggested cg, 65mm is not bad and should be fine. Overall weight is most likely your issue if it is trimmed right or even close. Maybe with the increased weight it is more touchy and needs to be right at 60mm..... try it. I doubt it though, that should make it more nose heavy.

Don't know your whole rig's setup but, I think you should be able to trim it out by sliding your LiPo back a little. I'd try sliding it back as far as I could get it, maybe program in a notch of up elevator trim & re-check glide. If the 'up' makes it work, set it there with your clevis adjustment so you can re-center your trim button on the Tx. FWIW, I put 2 different-colored dots under my wing with Sharpie pens, representing 60 & 70mm....and when I went to add another dot for 62mm, it basically just made the 60mm mark look like an '8'. So, I put the 3rd in the center to represent 65mm. My point is, the whole 10mm span ain't all that wide, & if you draw it out on paper to see it visually, the whole span is smaller than the width of your fingertip, which most use to check balance before launching. Ergo, when we're talking 60, 62, 65 & 70mm settings, it's a pretty fine incrementing. Please let us know how it works out for ya!

Frankly .. I never flew in in stock form (weight ) because I built it with the intention to use it for FPV ..so the best I can do is to fly it without the FPV dummy weight and with a smaller battery to compensate for the minimum necessary embedded CF reinforcements .. which are actually almsot impossible to undo without tearing the whole plane apart .. so here is the suggested new lighter weight I will do a test flight with AUW= 822 g (29 oz) with a 1300mah 3S lipo ...

Your assumption that I knew your Txs were equipped with 50 ohm resistors is just that, an assumption on your part. I simply ask you to reveal the name of the manufacture & model number of your Txs for the purpose of learning how they went about acheiving the pre-load when the antenna was removed. Now that you are once again responding, how about revealing to all of us the name of the manufacture and model number of your Txs. |
