Foam power

Iam not an expert, there are much, much brighter people out there’.

Having taught myself to fly using cheap foam deltas, main reason being they have great inherent stability, that’s the delta effect which I am told, is always trying to fly straight. ‘Not in my early flying days’.

Several different types of battery and engine combinations later, some expensive and some cheep. For me this is what I have found works well, ‘particularly when  learning and crashing on a frequent basis’, though it should be said foamy deltas do put up with much abuse.

  Anaverage size delta about 80 cm wing span, ‘remember the smaller the more affected by wind’.

 I used a 2212-62200KV Outrunner Brushless Motor found on eBay for about £08.00  or $05.50 swinging a 6x4 prop to be great. Plenty of power to get you clear of terra firma, the engine runs very cool and draws less power from the battery.

 

A 35 Amp ESC is good but if you can afford a higher ampere, say a 60 do it.

Kavan plastic propellers are really good as whist they are not a dedicated electric prop they are really crash resistant.  Also when learning you don’t need too much speed.Once I had mastered the basics I changed to a 7x4 which gave a higher speed,and less noise.

    All powered with a 3 cell11.1V 2200MAH 25C LIPO Battery and with the 6x4 prop will give an easy 25 min flying time.....

‘Much more than the brain will cope with when first learning.’

 ‘To summarise’,

Nothing wrong with More expensive engines and batteries but when learning I believe all you need is good cheap reliability. ‘When I started, I just needed to know what electrics to buy to get airborne.’

Modern RTF trainers are great but if you want steady cheap flying, safe in the knowledge  if you smash it up on Saturday morning you could build a quick replacement airframe or a repair which would have you back in the air by Sunday.

 So here is the list I wanted when I first started’:

1. 2212-6 2200KV Outrunner Brushless Motor

2. 35 Amp ESC or above

3. 3 cell 11.1V 2200MAH 25C LIPO Battery

4. Kavan plastic propeller size 6x4

Is that thing wrapped in tape? I bet its tough as nails though. What is the flying weight?

I've got scratch built Extra 300 that needs some extra support, but I fear adding that much tape might put it over the edge for weight.

Hello there,
Very well spotted,
It's extreme packing tape, or reinforced packing tape, basically its fibre glass laminated in to clear vinyl .. I am just writing an article about it... the weight gain is minimal, less than painting almost. It almost doubles the strength of the airframe. Again not my idea the combat flyers use it and they are always on the ground.
thanks for the interest

Good article! Cool photos and different text types. Maybe an other title like delta power system or something like that? 5 stars

I swear by foam planes! you have done a great service to teh foam community by posting this. I would suggest a prop saver possibly on the setup you have pictured; (unless you have landing gear of some sort). Any plans for this? It does look very easy to build. Thanks for the article!

i have used prop savers and you are quite correct they also really helped in the early days, very good point.

Glad you enjoyed it...beauty of the Delta is you always drop the power and it will slow fly really nice

This was an interesting read. Nice article! I have a delta wing using a 2217-10 1500kv outrunner and 8x3.8 slowfly prop with a 2200mAh lipo. For now, I like the slowfly prop because (being the beginner that I am) the slowfly prop doesn't really make the wing a "screamer" and it's slow enough to easily control and yet fast enough to fly and still have alot of fun with. I did buy a 2200 kv motor and 50amp esc to put on my delta wing in the near future.

Hello there,
Thanks for the comments, Deltas really do make great trainers and your quite correct once you are ready they will 'hot ship' also. Like your prop choice. I have just started experimenting with wing spoilers; if they work I will post the findings.
Regards
