Starting to think about a new build. I may have to use a different canopy... What do you all think? Strike hazard? Performance issue?
Prop clearance... How close is too close? |
08-Jul-2023, 09:09 PM Starting to think about a new build. I may have to use a different canopy... What do you all think? Strike hazard? Performance issue? 08-Jul-2023, 09:26 PM That’s awfully close. I’d suggest trying to flex the prop up and down and seeing if it can strike the canopy at all. Dangerous operations. Disclaimer: I don’t know wtf I’m talking about. I wish I could get the smell of burnt electronics out of my nose. 08-Jul-2023, 09:47 PM The front ones on my Flea build are maybe 3-4mm from the canopy. If the tips bend during a crash they catch and have to be bent back. So for yours, it will be fine as long as the props are on tight and screwed to the motors. If you have a crash, spin them using your finger and see if they catch, then put the quad in angle mode and arm it and if you hear that grating noise, disarm, check the tips. but as long as they are tough props that don't bend and you check after crashes, you should be fine. Try Not, Do or Do Not - Yoda 08-Jul-2023, 10:32 PM On some of my 5" builds if I run the 6s 1300mah battery laying on the wide side and with rubber/kevlar thick battery straps. The props are as close to the straps as those are to the canopy. Of course in that situation I can mount the battery on the narrower edge to give the props more clearance but I can't say I've noticed improved flight because of it. Or maybe it's less noticeable on 5" 09-Jul-2023, 01:51 PM The canopy could move around a little in flight. It's only made of flexible TPU after all. If it was me I would modify the canopy slightly to allow some little extra clearance for peace of mind. 09-Jul-2023, 03:47 PM Well, I realized it gets even closer when the canopy is fully tightened down. I can create clearance by raising it a few mm, but I'd have to use longer stack bolts and spacers. I'm looking at canopy options on thingiverse... 09-Jul-2023, 05:54 PM 09-Jul-2023, 06:17 PM That T-Rex is awesome. If it wasn’t for all the unnecessary weight, I’d totally start using that as my standard canopy. I might have to make a 3” or 3.5” overpowered toothpick just so that I can use that thing. Dangerous operations. Disclaimer: I don’t know wtf I’m talking about. I wish I could get the smell of burnt electronics out of my nose. 09-Jul-2023, 07:02 PM (This post was last modified: 09-Jul-2023, 07:24 PM by skywanderer.) Hahaha, it is awesome! Sounds like another "accidental build" could happen because of it huh?... fwiw these motors on a 3"er: FPVCYCLE 13MM 5000KV, 6350KV MOTOR - 2MM PROP SHAFT -SALE $9.99 https://fpvcycle.com/collections/motors/...prop-shaft ...measured out to be 13.25mm stator height and would pair well with 2S on the 6350kv & 3S on the 5000kv versions... just sayin... if ya might need some, they are on sale atm. 3.5" no worries at all edit: ermm that's 13mm width & 3.25 height... garsh 10-Jul-2023, 03:17 AM sometimes the rotors got some badair resonance by tightness, if it sounds very loud like a ducted quad - there might be decreased performance and efficiency. 11-Jul-2023, 03:34 AM Yeah, I was wondering about interference with flight characteristics as well... No worries, there are many options. lol. I decided to pass on the t-rex. I did print a couple of the Pickle Pod versions and a Nano Pod. The canopy in front (nano) is nice and sturdy but doesn't clear my vtx. There are a couple more I'd like to check out. At this point I'm leaning towards the integrated thumb mount. I'm also considering a color change to match red emax bi-blades... I've never actually tried them. 11-Jul-2023, 08:22 AM So… I printed a couple of these. At 9g, they are ridiculously heavy for a canopy. Still, I’m gonna make one of these dinosaurs fly- but it’s definitely going to have to be one of my overpowered 3”+ builds. My apologies for wandering off of your thread topic, drum. Out of the ones you posted, I really like the look of the bottom center one. You said it doesn’t clear your vtx? How so? I’m not too good at the 3d design, but I am capable of making some modifications to a design. Dangerous operations. Disclaimer: I don’t know wtf I’m talking about. I wish I could get the smell of burnt electronics out of my nose. 11-Jul-2023, 07:41 PM lol. It's all good... The vtx is an older happymodel version with an edge-mounted button for changing the channel. It also has the two plugs for cam/fc connections. The flat bottom blocks access to the switch (not that I use it) and the "bowing in" (for lack of a better description) for prop clearance interferes with both the switch and the plugs. If the nano canopy had the scalloped "feet" and straight edges of the pickle pod it would probably work. I printed four M2 spacers that I could probably use as feet but again, I'd have to use longer stack bolts... I'm trying to avoid that. I have a couple other versions to print and test fit before I decide. I realized, after the fact, that I printed the pictured canopies at 50 mm/s. They'd probably be cleaner if I slowed things down to 25-30 mm/s. It looks like the Trex printed pretty well for you... There are some *really bad* prints on thingiverse. lol. 12-Jul-2023, 05:00 AM (11-Jul-2023, 08:22 AM)Lemonyleprosy Wrote: So… I printed a couple of these.

Don't know if you've seen the PicklePik frame over at cncdrones?... Anyway, another option might be to scale up the arms to 3.5" size. There is a "digi" version of the PicklePik that will accept wider mounted canopy. (does not mount canopy onto flight controller stack!) Having extra room around the center = distance = why one reason the little 2.5" Geprc Phantom flies so well. I think... edit to find reference, found it: PicklePod_4-5Inch_v1-2.stl https://www.thingiverse.com/thing:3919273/files |
