Hi Stephen, I made the bottom fuselage half to begin sizing bits and pieces for the EDF conversion. The fan fits nicely between F8b and F9b and gives an exhaust cone that fits the technical requirements almost spot on. It looks like it will fit on the motor line you used for the prop version. The wing ducts will be too small so I decided I would need "cheater holes" to allow more air in the fuselage. I decided that I may as well use scale holes so I'm adding retractable landing gear and not closing off the wheel wells so the air can get in. That should open up plenty of extra air and I will make plastic scoops in the wing ducts so that that air is smooth coming in. The scale location looks to be between F5b and F6b. because of the extra weight I need extra performance so I'm using a 4S battery. I originally wanted to load it through the nose cone but the nose wheel foils that so I'm going with two 2S wired in series and located low down on each side of the fuselage. This will leave the centre for the Rx and ESC. The extra performance should be around 29 oz. of static thrust. So I think I will get away with it. I won't make the EDF a permanent fixture until I have it all working correctly. Will post some pictures when I do a bit more carpentry.

Hi Steve, what a quirky and neat model. Looking at the plan it shows the booms skinned in Ply but the legend says balsa. Which do you recommend? I have a great planes Synchro that has a 56mm EDF that may just work. The exhaust will be 50mm so not so scale but I can do retracts and the servos will also fit. So good bye Synchro, hello SIPA S.200. I plan to use the wing ducts plus a cheater hole in the fuselage for air. Jack Higgins Toronto.

Anyone know where you could buy scale spinners for the Short Solent Mk. lV? Papa, Toronto.

Thank you BEB. I went back and took another run at it and found it. Dec 2010 and Jan 2011. Thank you now back to our 6" of snow and -26C tonight. Imagine that in a shed no wonder we all have basements. Jack.

Hi can anyone tell me the dates of the magazines that carried the articles by Tony Nyhuis on his FG technique? I'm doing my nut here and not finding them. Thank you. Jack Higgins, Toronto.

Thank you both, I will try Southampton and also check Profili for something akin to those numbers. They would not have used an RAF airfoil would they? Jack.

Hi, does anyone know what airfoil was used on the A-1 jet fighter flying boat? Thank you, Jack Higgins. Toronto.

Good morning Tim. The satellite had just failed for no apparent reason. When tested it was just dead. Never been crashed etc. Everything worked fine when a new satellite was installed and rebound. That is until it all failed.  Jack HigginsToronto.

We just had an AR7000 go off at the field. A new Hanger 9 Mustang on a maiden. Complete write off. As the pilot sensed a loss of signal the retracts started to deploy The model just went straight in from about a hundred feet. Transmitter and Rx have been returned to Horizon at their request. If we get an answer I will post it here. The satellite had been replaced with a new one a week before. Two good lights on start up so the Rx seemed OK. Jack Higgins Toronto.  

It's got to be 14. My last address in Dublin.

Good evening Steve, check out this video and you will see the speed of the electric retracts. Not quiet prototype but not Bang Bang either. Jack Higgins http://www.youtube.com/watch?v=N_s0vFIvfjo&feature=player_embedded   

I hope you will consider using electric retracts rather than the an air system. They are the future to my way of thinking.. Jack.

Great plan of an intriguing prototype. Congratulations Glenn. The original had the winglets at 23 degrees and yours are a lot less. Was there design reason for that? Jack Higgins

Since the wheels go into the wing root could you open the top of the wing so the wheels protrude into the fuselage? This would keep the wing thickness at scale but it might be tricky to keep the strength. Jack Higgins.

Back a few pages someone mentioned about a kit for a Vulcan. I recalled that there was one but it just came to me where I saw it. http://www.southhertsmodels.com/Vulcan.htm This is a 6' wingspan and might be suitable for 4 EDF's??? Papa.

Tony, thank you for the link I thought they had gone out of business.Alula if you had an opportunity to be at an air show where the Vulcan performed and saw and heard one up close it would have made a lasting impression. There was something surreal about a wing that size staying in the air at such a slow speed. I have been a fan ever since I saw and heard my first at the air show in Toronto. Papa.

I'd build a B&V just for the heck of it. It would be another War bird. 1/8th scale would be around 85" span. With a big electric motor and a battery in the cockpit it would be neat. Would there be a lateral balance problem since the CG would likely be off set to one side? I'd build it just to be different. You won't see many of those around Toronto.. Papa.

Good afternoon ERFOLG. I'm curious regarding your last sentence above. Could you expand on why you would not consider 4 DF's. even using name brands the cost is not too bad and it's even less if you use Hong Kong knockoffs. The E-flight 69mm unit gets 2.8lbs of thrust on a 4s battery. 4 would power a pretty big Vulcan B2 with lots of margin. The new electric retracts are just begging for something like this. Papa.

Four is what I had in mind. Simple, four tubes. Have you seen a HABU in flight? Four of those units would move a larger model with ease, I think and the sound would be great.  Papa

BEB that was my point. If TN sorted out an EDF setup then a lot of folks would go for it knowing it has all the kinks worked out. Regardless of your time of life a Vulcan will never be too fast. Papa.

I agree with BEB and ERFOLG. The reason I suggested the Vulcan some time back was that I would love to see TN explore the new developments of EDF's. It would be an impressive model, relatively easy to build, the way TN designs, and would be reliable. Think of the sound of four 70mm EDF's tearing down your patch. it would tick all my boxes and then some. Jack Higgins.

What a fascinating forum this is.  I'm all for the free plan which is why RCM&E is the only Magazine I have a subscription for.  I rarely buy local North American publications.  Back a couple of years Chris Reid did a Scottish Aviation Pioneer. Mine will be maidened in Spring now that my flying skills are up to the task.  How about Tony doing a Scottish Aviation Pioneer with full working Fowler Flaps and working slats to add complexity (challenge). It would be different to fly and will never be an ARTF. 60" - 80" would be great and with the newer more powerful electric motors power would not be an issue.  My point is maybe revisiting a previous design but doing more with it might be a way to go.   Jack Higgins

Good morning Erfolg. I think your perspective is that of an experienced modeller who came in by way of kits and moved on to scratch because manufacturers did not kit what you wanted to fly. Now when a newcomer goes into an LHS they are confronted with ARTF's which are the new kits of this age. My experience here has been that the newcomers are dismayed when they break an ARTF and don't have the skills to repair it. Then they turn to experienced builders for advice. This in turn leads them to kit building and scratch building.  Right now in our club of some 60 electric only flyers at least 5 new members, that I know of, are building. I get two or more e-mails a week asking advice and our forum is full of construction questions. I think that we are in a state of transition but I''m very optimistic regarding scratch building. I noticed that my LHS has a bigger variety and supply of Balsa and they report demand is up.  Ask around you might be surprised how much building is going on. I'm very optimistic about the future.  Jack Higgins   

With the advent of good inexpensive EDF's what do you think of a four motored Vulcan or early DH Comet or in its later form the Nimrod? While not WW ll they are war birds and in one case also commercial. My personal favourite is the Vulcan. An absolutely beautiful plane in the air and that sound was so memorable.  Jack Higgins
