I know what you mean, John. I think the camera distorts it a bit though (only a bit mind)! surprise

I don't know if it will apply with an electric installation but on the larger petrol models the carbon spinner backplates have been known to soften with heat causing prop bolts to loosen with drastic consequences. I got one for my 2.6 metre Edge but luckily had a spare aluminium backplate which luckily mated with the spinner body. This may not apply to your electric set up as I have no idea how much heat they generate, it's all looking great by the way your build logs always make for a good read

Ultymate. I have not so far had a problem with 3.5" spinners of the same type using an electric set up. Any heat generated by my electrics seems to disappear out the back end grills of the plane and don't seem to affect the front. Something to watch though. As a matter of course I tend to check the prop bolts every two flights.

Glad you like the build log. Appreciate your comments. Still a bit more to go. laugh

The bolts arrived from Model Fixings.

I have had to pack the bolt out with spring washers to get the bolt to tighten up properly due to the bolt thread being longer than the thread in the prop shaft.

traced the prop profile onto the spinner and marked it clearly.

Transferred the mark to the spinner.

Now to cut the spinner. I have marked the prop on the spinner base plate.

A bit of Dremel work and we are done.

Next I finished off the RX battery tray and added velcro.

Time to check the CoG again.

p1050521.jpgDespite what the photo appears to show, with 6.2amp lipos installed and the Rx positioned rearwards, the nose still dips downwards a tad. With the 5.0 amp lipos the plane is nearer in balance. I am thinking it will be better to just go fly with it and just see how she goes. First I have to attach the decals, but ran out of time today.

Well done Adrian.

From the photos it looks like orange spinner is OK as it is.

Thanks, Gary. Yup no further work needed on the spinner. Stays as it is. When I get some decent weather then it is maiden time. I will post a video here when I do it. Will report back on CoG and flying characteristics too.

Well took Rich & Ron's advice and took 8-9mm off the bolt thread.

p1050522.jpg

All went well using a Dremel with a cutting disc. Oiled the bolt before screwing it into the prop shaft. Fitted absolutely fine and the bolt head is now flush with the spinner.

Next up I added the decals. Now I believe in the adage "less is more" and I applied this to adding the graphics.

p1050524.jpg

I really didn't see any more need to add additional decals. Next I will be waiting for decent weather to do the maiden flight. More when that occurs plus a video.

Much better yeslaugh I use a Dremel to cut and then grind a chamfer into the end of the bolt.

I used a file to chamfer the edges, as I thought I might be a bit too aggressive with the grinding bit with my doddery hands! blush

Well it would be,Rich. Apart from the fact it is a moderate 13-14 mph crosswind in sunny Suffolk something under normal circumstances I would fly in, but not really for a maiden. I really want any wind straight down the strip one way or the other. dont know
