White Shark from Multiplex

Don't get confused. It is just a new name for the white TJ. Doesn't this model ask for a US NAVY Tomcat color scheme?
Were can I find some Wolf Pack decor? Jürgen

hmm, this white twinjet seems a good idea for custom paint jobs of any nature. plane art?
any how, i downloaded a tj video from www.andreasscholl and jurgen you said it was brushless? but it's performance seems more or less the same as a stock twinjet? i've seen that clip before but re-downloaded it when i saw the thread that said it was a similar setup to yours and yours had rocket qualities!
i might go brushless EVENTUALLY as long as i can hook up both funs off the single esc, i don't need fancy variable dynamic thrust variation like you but want to save SOME dosh instead. question is, there are different turns of the FUN 400 right. 23, 28 something rather..... can these motors take ten cells? 10x2000? i know you'll say i don't need them but they'll be the same ones i WILL use in my e3d which i'm getting in oh, 2.5 months or so i can't avoid this ten cell thing and really, really don't want to buy the 9.6v packs. again, dosh saving.

Peter

do these new white n' blue twinjets come with 480's or not? twinjets are good value now £60 new, quite amazing

Hi Peter,

Can't remember the video from Andreas Scholl and your link doesn't seem to be working.

You can buy the Twin Drive from Kontronik at www.hoellein.com for €322.- (2xFUN400-23 & 1xSMILE40-6-12). Going to 10 cells I would use the new CP1700 and save even more weight. Jürgen

Amazing - nobody noticed that I have used "White Shark" instead of "White Eagle". It is either that or "Blue Shark" for the blue version. Jürgen

@Gerard - Yes the new material is also Elapor.

yeah, the link wasn't meant to work properly more to refresh your mind.
so the blue n' white tj's are more compact foam therefore of higher quality? and do they come with 480's?!
i wouldn't want to use cp cells of lower capacity cos i don't want miserable run time. i realise you could get what, 3 mins? but the packs are also for e3d and i want good flight time for that.

Just checked the weight of the foam parts of a standard TJ - they were even heavier! Obvoiusly the weight varies from 240g - 300g! 288g for the white foam parts is obviously within the normal variation.
Yes, the White Eagle and Blue Shark come with Permax 480s as standard. With 8/CP1700 you should still get about 4.5 minutes at continous full throttle. Jürgen

jurgen, i am sure this has been asked before, but i really would appriciate an answer instead of to go through a zillion twinjet threads again.
i want to get the drive set suggested by you at hoellein, but what kind of duration can i suspect on my packs ?
i have 1700 mah src sanyo packs in eight, nine and ten cel configurations.
i really would like a estimate on flight times so that i wont be bummed when i spend all that cash on those brushless beasts

Whatever you want - your choice. Using 10 cells you are drawing up to 40A from battery pack using 5.5x4.3" props. You can drain your 1700SCR in less than 2.5 minutes. Using the same props but only 8 cells, the motors will only draw about 24A and you will have about 4 Minutes at full throttle, or you use bigger props and get the current up to 40A again. Jürgen
P.S.: Whatever you do - you will have a much more efficent drive system which is maintenance free and will keep its value.

thank you for your reply jurgen ! i appriciate it very much.
on 8 cells (4 mins flight time seems nice) how does the performance compare to the graupner competition set with the 2 480L's ?
i mean, when i spend such an ammount on 2 motors i really hope that it is worth the money

what i want to do see, is install some 480L races on 10 cells and get used to that setup. then when i have loads and loads of savings, go brushless only if i get my verticle on 12v. would the stock 480's be able to handle ten cells for any length of time then?
i think i'll paint my twinjet also, people say it is impervious to any type of paint. if this is true i'll just get some nice car paint and spray that on prior to priming and finely sanding the plane.

Hi Gerard,

Assuming you get about 60-65% max. efficiency from the 480Ls and about 88-89% from the FUN400-23, you have 37-46% more power at the same duration!

Hi Peter,

If you use some throttle management you can make them last quite a while, but even then: 12V are pretty tough to an untimed commutator (arcing etc.) Jürgen

will this fun combo 'lift' 10x2000 perpendicular to the earth's crust?
and what's with the FUN-480 motors?

Why 10/2000? 10 CP1700 are lighter. Why FUN480s? FUN400 are lighter. Jürgen

P.S.: Does anybody have some decals for a F-14 VF-1 "Wolf Pack"?

Blue Shark

I was wondering where you could find the blue shark on the web. The only one I've seen is the white eagle. I haven't even heard of the blue shark until now.
