Cambrian Spitfire Mk IX Build Log
Geoff Gardiner replied to Geoff Gardiner's topic in Build Blogs and Kit Reviews
OK, so I am thinking about what motor and battery combo I am going to use before I start building the fuselage - in case I need to make any modifications. I would like to use kit that I already have, to try and keep costs down. Namely: Lipo Battery - 5S 4000mah Motor - I have two to choose from, both Overlander Thumpers. These are the Specs 1. Tornado C4250, 600kv, 720 watt max, 3-7 Lipo, 45A ESC, Prop from 10x5 2. V2 T5045/10, 720kv, 1250 watt, 3-7 Lipo, 80A ESC, Prop from 13inch The suggested average weight for this Spitfire is 5.5lbs. Do you think either of these combos would be suitable? I am thinking the 2nd option but I do get a bit confused with all the numbers. Any advice gratefully received. -

Looks lovely. What size wheels are you using? I think they are smaller than my ones, I used the scale sized ones which did mean a large wheel well. Keep going! CS I am using 70mm diameter wheels which I think are roughly about scale. -

Good Info - thanks. I will avoid flaperons. A few more pictures to bring things up to date: Glue in the retract mountings using Gorilla glue (the foaming variety). Test fit retract units. This is my first experience with retract units and I have found that, due to the angle that you have to mount the unit, the wheel well has to be much bigger than the wheel in order to stop it jamming on the edge. Is this usual or do I need to put a bend in the leg? The video below, which I made before I switched the trailing edges, hopefully gives you an idea of what I mean. The wheel just about clears the edge but I am concerned that if the leg gets slightly bent during use it will bind. More later... -

OK.... back on track (I hope). I had put the wrong trailing edge on the wrong wing half. I decided the easiest thing would be to cut the rear spar in half and swap everything around as a unit. Sanded the edges flat and glued back on correct wing half. Bit of filler and a final sand and I think it should be good to go. One thought. The design is for a single servo for the ailerons but I am thinking it may be better to use two, thus giving the option for programming flaperons. What are you doing CS. More later... -

Oh darn.............. it was going so well! Thanks everyone for your comments. Yours looks great CS - is it finished yet? I intend this as a warts and all build log, as I'm learning as I go, and here's my first wart!. Looks like I have no choice other than cut off the trailing edges off and put them on the correct way around, unless anyone has a cunning plan. -

OK.. here's a bit more. Glue on the leading edges and rear spars using Gorilla glue Then glue on the wing tips. I had to add a bit of scrap balsa as the wing tip was not quite thick enough when centered. Laid out the wing just to get an idea of the shape. Then attack it with the David plane and create a bit of mess. Bend the wire aileron cranks taking care to get the angle right and glue on the inboard trailing edges. More later... -
