I second that - got 4 sheets of 6mm waiting!

I think the other good thing about 48" for training is that it gets you used to the increased adrenaline - that was my experience anyway - the bigger they are the more scared I am!

Got through 3 more batteries worth this afternoon , freezing cold though

My experience is that bigger models are easier to fly as they are not as twitchy, have a lower wing loading and are easier to see. You can still use your smaller packs by using a lead to connect two lipo's in parallel. Make your own up or buy from here http://www.giantshark.co.uk/parallel...-p-406366.html
My order includes some of the grey 6mm sheets that are longer at 1250mm which is 49.2125984 inches so it's game on for a 48" model.

Yes I'm sure you are right, it's just that physiological thing I think. Perhaps it's just that I link size with !!!!

There is a downside with larger model. They are heavier so don't tend to survive unexpected and sudden contact with terra firma (or should that be terror firma?) as well as smaller stuff.

If gravity doesn't get you, the magnetic trees will

hey guys, ive had a few more flights out of my wot next, and although im highly impressed by just how docile she is, i feel ive done something wrong.

all my rates are set to low,

my problem is that she climbs under power, and i have to apply alot of down elevator to compensate this climb, if i back the power off, so she can cruise at a steady pace, then she will fly nice and level.

my motor is set with no off set what so ever, but i did modify the design to give me a kfm2 wing,

should i just scrap that wing and build as per plan, the flat wing? (i built the kfm wing as i hav had great experience with them in the past with my BB, and i didnt have much in the way of being able to re-enforce the wing)

thanks

my setup atm =

1300mah 2s turingy lipos
1100kv supomodel bell type brushless

gws 0947 slo fly prop

the wot next is actually better built with its flat plank wing... the stiffer you make the wing the less docile it becomes..

the "constant climbing" is simply a result of the extra lift generated by the kfm section wing.

no need to build a new wing.... just add a couple of washers between the top two motor mounts and the bulkhead to give around 2degrees of down thrust to the motor and that should counter the extra lift

lol at the magnetic trees

you should fly by me, i had a close encouter with a tree the other day, and all it did was spit my plane out...... i dont think they like the taste of foam round here

@ how much.. thanks for that fella, will give it a good go, and see how she goes. i thought it might just be a case of adding a couple of deg offset onto it.

my wing is increadibly rigid, thanks to the kfm construction and the re-enforcement i found from a cheap kite.

its only docile as she has very little in the way of throws.

once i have her flying as per description, and i have gotten a few hours under my belt, i will increase the throws to liven her up a little and take her off the leash

maybe you should tell him, learning to fly an rc plane is more mountaineering than piloting...
