Do you really notice that big of a thrust difference between the XL and normal Nitro? Or was that an exaggeration by Aviator? Quote Link to comment Share on other sites More sharing options...
AndyB Posted April 29, 2018 Share Posted April 29, 2018 With the same engine, maximum thrust should not be much different. Certainly not different enough to notice. Quote Link to comment Share on other sites More sharing options...
Guest chrisg547 Posted April 29, 2018 Share Posted April 29, 2018 I read (not sure in this post or one of theres without checking) Vince reckons the prop screws through the air differently when airborne. But not much noticeable difference on the ground. But swinging the bigger prop his rpm's seem to be a lot lower for the given thrust. This really interests me from not just the economy end, but primarily about reducing the noise to protect my hearing. At 5500-6000rpm on a Moster its fine but over 7000 I'm not keen on how much noise I am subjected to (NB. I wear foam ear plugs and Peltor 3's) Even with both these though a lot of what you hear/feel is the noise vibration through your body/head. (Obviously you could say that PPG is the wrong sport to be involved with if you're worried about damaging your ears from noise but lets not go down that road).

Wrong, with a slightly bigger propeller you get at big difference, with a much bigger propeller you get a huge difference. Miroslav explains it best with this video.

AndyB Posted April 29, 2018 Share Posted April 29, 2018 I didn't calculate it, but you are right. I was just guessing that for Nitro vs Nitro XL should be around 10 kg thrust difference. I didn't think this would be that noticeable . I have just tried putting the figures in a thrust calculator and calculated the difference....and got 63 Kg vs 78 Kg! We would probably notice that! Figures could both be higher as you have to make some assumptions when doing calcs. I used the same assumptions for both These figures are the in flight difference. On the ground the bigger prop does less well (but should still be higher) as it requires the moving airflow. Quote Link to comment Share on other sites More sharing options...
custom-vince Posted April 29, 2018 Author Share Posted April 29, 2018 Yes I notice a big difference on the thrust when flying. More so than I expected, it was surprise to me also. Chris. If you want to protect your ears, try ANR it’s the only system I found which combats the noise coming through skull vibration. It’s a simple test, put your fingers in your ears and humm. You hear yourself, much the same with plugs or defenders. With ANR, your own humm is very muffled, quite bizarre. Bose QC20 is working for me, need to shield from wind noise is all.

Casper Posted May 2, 2018 Share Posted May 2, 2018 Hah! price go down, not a chance! It's still a superb product that will be on the market for a long time. But I seriously think they will do a major update in a couple of month, or early next year, based on the latest development. Quote Link to comment Share on other sites More sharing options...
custom-vince Posted May 2, 2018 Author Share Posted May 2, 2018 With the R2 frame development and the switch from alloy to magnesium. Price will increase slightly. The R2 has a more complicated build process with a few more features plus 2 sizes. The magnesium delta machine will be the new price competitive option while also greatly improved over any standard alloy product. I think this will raise a few eyebrows. Magnesium is lighter and stronger than alloy. Quote Link to comment Share on other sites More sharing options...
AndyB Posted May 2, 2018 Share Posted May 2, 2018 I am guessing it is magnesium alloy? There were results published in 2015 saying the latest Mg alloy was lighter than Al alloy but as strong as Ti. Quote Link to comment Share on other sites More sharing options...

Supposedly all Nitros from now on will come with the V2 frames, which is the updated Race and the new Magnesium. Eric said magnesium should be about $250 more than the aluminum one. Supposedly all Tornadoes come with the diamond coated interior, making them stronger than the nickle interior that the nitro has. I wish they would upgrade all future nitros to the diamond coated interior as well. But I haven't heard anything about that. Quote Link to comment Share on other sites More sharing options...
custom-vince Posted May 5, 2018 Author Share Posted May 5, 2018 A quick video from yesterday, mounted a gopro session 5 directly to the frame, it shows some vibration, not bad though. Flying Nitro XL level flight, Natural sound, no music. You can hear the difference flying out on slower trims and flying back on faster trims. Ozone freeride 19m, I’m 84kg plus clothes. I have a foot camera also gopro 3 Silver , have not seen that footage yet. The newer session WiFi connect to my phone, the older gopro does not. 2 Quote Link to comment Share on other sites More sharing options...
The80s Posted May 7, 2018 Share Posted May 7, 2018 Nice vid. I like the low droning sound of the XL better than the sound from the smaller Nitro. What size is your fuel tank and what's the farthest you've ever traveled on one tank? Quote Link to comment Share on other sites More sharing options...
custom-vince Posted May 8, 2018 Author Share Posted May 8, 2018 (edited) I have not flown long XC with it yet. I launched with 4.5 litres and landed with 2.8 litres left after 45 minutes flying. I took photo before launch and after landing. I need another pilot to fly a similar setup and confirm. The freeride seems economical when combined with XL, plus I had 20 mins full trims out. no bar.

The80s Posted May 9, 2018 Share Posted May 9, 2018 How many engine outs have you had with the XL? What were the causes? Quote Link to comment Share on other sites More sharing options...
custom-vince Posted May 9, 2018 Author Share Posted May 9, 2018 (edited) None. None on my previous Nitro either. Only engine out I have had was fuel tank vent on a black devil. Edited May 9, 2018 by custom-vince 1 Quote Link to comment Share on other sites More sharing options...
custom-vince Posted May 10, 2018 Author Share Posted May 10, 2018 Made the most of another nice evening. Low flying and punching the throttle a bit more while turning etc, I burned a bit more fuel. Best I can judge, about 2.7 litres in 50 mins. Landed with a little under a 1/4 of a litre. (Very low ?) chrome dome is back 1 Quote Link to comment Share on other sites More sharing options...
Lee Jackson Posted May 11, 2018 Share Posted May 11, 2018 Cool Vince. As you were ripping around low I see you flew through some bonfire smoke or something similar... did it throw you about a bit, or was it nothing to write home about? I ask because I've always avoided warm rising BBQ/bonfire smoke - thinking I'd be doomed! Quote Link to comment Share on other sites More sharing options...
custom-vince Posted May 11, 2018 Author Share Posted May 11, 2018 Good question. I did get a little wallop from that. Felt the heat and got a single bump. As I passed to the side on the way back over you can see my right brake handle lost pressure, I would guess from the mushroom swirl of heat rising, there’s some sink around it. Anything bigger I avoid for sure. Quote Link to comment Share on other sites More sharing options...

Yes I know, I live in the country surrounded by the stuff ? Townies struggle if I say I love flying over all the rape. They cunjour up a different image. My local farmers have a lot of rape this time of year. Good time of year for a lot of rape in the fields when the suns out. See what I mean? I’ll just call them big yellow fields. ? cause they are yellow, big and fields. lol. Quote Link to comment Share on other sites More sharing options...
