FT Spitfire Build

It might well be, so will need to shove the battery forward. It still has the tendency to fly to the right, despite me adding side-thrust.
I have mine as far forward as I can get it with 7 grams of weight added, and I built a cover for the bottom as I find that this model and the FT Racer(which also needs the battery as far forward as possible) have a tendency to eject the battery and cause more damage without it.
 
Yeah, my landing was a bit harder than I wanted, and the battery popped out. Definitely gonna make a cover.

As for being tail-heavy, mine has 30g under the motor to balance it out. Might still need a bit more, though.

Its been awhile since my last FT Spitfire builds. The first was a SBK and my second a scratch but I don't recall having a problem joining the wings as I have with this recent scratch build. Firstly I noticed that the top and bottoms of each of the wings where they should join are not flush - should they be ?. Secondly should the spar for each wing be the same or should they be mirrored as is the case on the version 1.1 drawing ?.

Hello All , OK here I go , after doing as much research and asking many questions on the FT forum regarding my first foam build , I have decided to buy the FT Spitfire speed build kit (when they actually come back into stock in the UK) and give it my best shot . I dont think I will have too many problems with the actual build as over the years I have built various model kits and scratch built boats . The problems I have to overcome now is knowing the best / right electronics to fit into this kit and how to carry out any mods that will improve the flight in general , hence the questions
I intend to strengthen various areas in the kit with thin ply or balsa wood (depending and then when completed I will weigh the finished model and hopefully come back to the forum members for good advice on which size battery to use etc . Obviously I am aware of helping to keep the overall weight reduced as much as possible and would ideally like to make this kit with detachable wings if I think I could make a good job of it . I dont really want to aggressively fly the finished product to the point of increasing the chances of a bad landing / crash that will over damage the plane so nice and easy does it for me within reason. some of the areas I would likely reinforce are the all round nose section , the wing tips and the wing spars (inside the wings) , also also lightly reinforce the inside side fuselage from the wings to the rear of the plane in case of a bad landing that may snap the fuselage behind the wing section ( as Ive seen on some crash videos)
I would also like to fit a 57mm Durbo spinner as I think that is the right size spinner to fit for this particular model ? and due to advice I will stick with a two blade prop ( 9x7) ?? or bigger and I know this probably depends on engine size etc . I am not sure about the right configuration yet regarding fittings and electrics but can anyone give me advice on the use of a RC with reflex gyro (self stabilising) features with beginner and intermediate modes ?
Some of the other mods Im considering are:
Using clear strong film / tape on the undercarriage of fuselage to prevent too much wear / damage (strengthening)
Back the first two formers with thin ply to strengthen area in case of a bad landing ?
Compress the tailing edge of the wings between two pieces of wood to help streamline the plane in flight
I am not sure if the leading edge of the wings are pre rounded but if not then I would fit half round 4mm balsa dowell and tape over the full length to help make the plane more aerodynamic ?
I know this seems a lot to do but I want to give myself and the plane the best chance of a good flight and I really dont mind taking the time to do this , but I would like to know your thoughts on any of these mods and ideas as Im only starting out as a Newbie.
Thanks in anticipation of any advice offered

I've built 3 FT Spitfires so far but only flown 2 of them. The first was a SBK and the second and third are scratch built out of DollarTree foam board. I crashed the first one several times until it was no longer repairable. The second one (its my profile picture) is equipped as follows
  • FT Power Pack C - Radial
  • Gens 3s 2200mAh (25C)
  • APC 9 x6 E prop
  • Radio Master R161 receiver
  • Aura 5 Lite
Regarding mods I used my "low profile" power pod

I also added fixed landing gear and a steerable tail wheel as I fly at a local club that has a runway.


The plane is a little fast for me as I am not an experienced pilot but the Aura has helped me avoid crashing.
