Can anyone suggest a suitable first twin project, plan or kit suitable for 2x Saito FA 40a engines please?

Exactly as I have been doing David, only the gods were not smiling on me. What size is your frame, A3? I shall have a look at Trent Plastics.

Lucky with my 1/4 scale Gull. I picked up a perfectly sized canopy from a box of bits at a show.

I still have the female moulds for the grp u/c pants but mine are the long version which I prefer.

Martin, the frame is 460mm X 260mm

Looks great ,

What thickness of material do you use and what temp for the oven and how long would you say..

I know its trial and error for the part you are trying to form but some pointers would be useful please

Steve

Hi Steve, I used 1mm PETG bought from Trent Plastics, oven temperature was set to 230 degrees C and pre-heated for about 5 minutes. PETG was in the oven for about 3 minutes and I had to turn it half way as it was sagging quite a lot more on one side. I waited until the PETG was sagging by about 3" before attempting the 'pull'.

Why do you not get creases from the plug to the corners of the vac former? My last few attempts have been useless because of this problem.

Well, probably more luck than design as I am no expert at vacuum forming, this being my first attempt. What you see in the video is actually my second attempt as I did not heat the PETG enough first time and ended up with a perfectly formed 3/4 depth canopy. I watched as many YouTube video's as I could find of people making all sorts of vacuum formed components and noticed the problem of creases forming at the corners. To try and counter this I made the plug about 1/2" deeper than it needed to be and then later also spaced the plug up from the vacuum form box by another 1/4" because I felt the 1/2" already added might not be enough. After the second successful attempt I did in fact have a couple of small creases but these were lost when the surplus depth was removed.

If I do this again I would just make the plug a good 3/4" deeper than needed. Other than that I guess it's down to heating the PETG to a high enough temperature and having good suction. Hope this helps.

My Chorus Gull is finally finished so here are a few photo's taken along the way. I based this on the David Beale Mew Gull replica, and also scaled the plan up 20% to give the model a wingspan of 6ft. Scaling up meant I had to make my own canopy, so I will add another post with a video showing production of the canopy...chorus gull wing.jpgchorus gull wings.jpgp1040167.jpgfus-1.jpgp1040175.jpgfus-3.jpgfus-4.jpgcowl-1.jpgcowl-2.jpgengine.jpgmew gull-1.jpgmew gull-2.jpgcg-a.jpgcg-g.jpgcg-j.jpg

I've just looked and I have a tin, just over half full. But it's in France. You are welcome to it, for the postage cost.

Thanks Don that's very kind, however, I have decided to go with what I currently have. It's not a perfect match but its very close. I used Rust-Oleum Cardinal Red which also appears to be fuel proof judging by its performance on my Acro Wot - time will tell.

Thank you to everyone that responded. I'll just post a picture of how it currently looks. The fuselage is covered in Fokker Red Solarspan, the engine cowling and nose have been sprayed with the Rust-Oleum paint. The colour match is not quite as good as the photo would suggest but I'm going to go with it now; its taken a year to get this far and I'm looking forward to moving on to the next project.

David, I'm fairly sure I saw a tin in addlestone models the other day tucked away in a corner, worth a call? there open from 11 today.

Thanks for the suggestion Paul; called at 11am this morning, but unfortunately no luck again.

Have you tried ringing Solarfilm direct. I have been able to order a roll of Silver Solartex from them a couple of days ago. angel Worth a phone call at least.

Edited By Low pass Pete on 15/12/2019 05:26:10

Hi Yes, tried that, no luck unfortunately.

Does anyone have any Solarlac Dark Red they would be willing to sell to me?

Thank you all for your suggestions; much appreciated.

I have at last started covering my Chorus Gull and I want to copy the red with gold trim as here. I will be using Solarspan for the red but have not yet sourced anything for the gold trim. Any suggestions as to what I could use? Will all the different types of covering stick to Solarspan? Any suggestions would be appreciated.

Can anyone advise on a good source for PETG sheet .020" (0.5mm) thickness as I am going to attempt vacuum forming a canopy for my Chorus Gull.

I have built a scaled up version (6ft span) from the Brian Peckham plan and so the 'standard' size canopy is too small.

Ebay is your best bet here, there is plenty on there in various sizes, thicknesses and cheap. I usually just stick to the UK sellers and there are plenty of those.

I normally buy from there if I can't get to a hobby shop. I make quite a lot of windscreens for Scale RC helis. I can confirm it does work very well with a Vac Former too as I have one and have tried it. I find 0.5 to 0.75 mm best to work with on the Vac Former. 1mm can be done but best only for very simple shape screens.

Mark

 

Thanks for your helpful response Mark. The canopy itself will be about 300mm x 300mm then I need to allow for overlap and fitting into the frame, so I need fairly large sheets. I have been struggling to find the size I need and prices were higher than I expected. I have looked on ebay and while there seems to be plenty on there, not found anything suitable yet.

Well that could be the response to virtually every post with a question. Fortunately there are more helpful people here who appreciate you have probably already done that, but that someone else may have managed to 'dig up' something you did not find.

Does anyone have any experience with Hangar One kits? I am particularly interested in the Curare 64.

Can someone please advise how I post an MP4 video from my PC. Originally taken with my mobile phone. Note this is not a youtube video but one taken with my mobile, now residing on my PC.

Thanks.
