In the initial stage in building the fuselage it became apparent we was going to have Fuel tank issues as the tank specified was clearly intended for competitive flying giving you just enough duration to fly a schedule. Experience dictates that fitting 14oz tank is the correct size using a 60/90 engine for everyday flying giving roughly a 10min engine run. Looking at all the readily available tanks it was looking like 10oz was the maximum size that would fit simply because clearance was required for the fuel lines up at the bulkhead for the engine pump unit? In a flash of inspiration I remembered I used to use Mk & Tetra tanks. A quick search and I found that a 14oz Bubble-less Tetra tank would fit (just). This was obtained from Central Hobbies. As you can see the tank just fits but a Well is required cutting into the wing to clear the tank. To be Continued Sam

Unfortunately Work Work Work has got in the way of Arrow, so finally this week end we have managed to find time to crack on with the final stages of the build. Time to join the wing panels. Wing Panel with the top surface laid flat then raised 5mm up at the root then weighted with wedges holding the wing center line true in position awaiting the opposite panel to be offered up Wing panels aligned and glued together using 15 min Epoxy.

Posted by Sam Wragg on 24/02/2015 15:39:33: I can see the merits of a national model center but I can't see it working due to these factors 1 Fun police / jobsworths 2. Inconsiderate modellers who think they can do what they please. 3 impracticable for most people to go there and fly 4 it will only end up benefiting the chosen few. Am I being too cynical Sam

Posted by Gary Manuel on 08/02/2015 18:54:15: Posted by iqon on 08/02/2015 10:03:46: End of day 1 on jig...going o`k Iqon, I'm not seeing the photo in this post for some reason. Well I was expecting to see a 2m F3A plane when I read the title. Not sure why others are having problems. I might build one myself if Iqon manages to keep his under 5Kg and it flies well. There are not many self build F3A models around and this one in certainly different. confusion is the key element here Gary, in F3a circles there is only 1 lightning and that is the model which Dave Hardaker designed and flew to great success in the 70s. I agree that there is not enough 2m F3a kits available & that's why I'm following with intrest even though Inicially I was expecting a Dave Hardaker lightning build...... but nevertheless pleasantly suprised even though there may be a copyright infringement Sam

Sense of humour required........ When i saw lightning F3a I expected to see the original model being built and not a 2m model (maybe a slight edit to the title to avoid confusion),,,, no doubt if the boot was on the other foot? you would probably react in the same manner. Nevertheless following this thread with intrest so carry on regardless Sam

Posted by lightning 759 on 31/01/2015 13:32:11: hi looked at title thought great , had a look at thread not a proper lightning NO AVONS shame andy I thought simular..... as in expecting to see the one and only original Dave Hardacker Lighning Sam

Its an early turnaround model possibly from the early 90s, I've been following it since October. The model is very similar to a Summit. Sam

Now that the servo recesses and cable runs are cut into the wing panels I can now start on the servo boxes. There are a couple of ways to do this operation, this is my method. First cut the well floor to fit the recess using 1/16 balsa Place the floor lining into position(not glued) then make a cardboard template of the sides and cut the 1/8 balsa to fit. Using super glue tack the balsa side to the to the balsa floor whilst in situ. Doing it this way allows you to achieve a perfect fit of the servo box Servo box withdrawn from recess with surface marked out. (JR servo) Savox servo Align servo to the required position Bearers position marked out Same with savox Modified Router with 1/8 ply fastened to the base with guide edge glued in position Machining slots for 3mm light ply Bearers Machined slots Light ply bearers glued in position with thin super glue wicked into the joints (on the inside) Access for servo cable cut in. Final trial fit before gluing in using Gorilla glue. Finished wing panel. All that's required before joining together is drilling the access holes for the retract air lines. Sam
