Ripmax - "Spitfire"

This kit was acquired from a fellow club member in June of last year.
It was released by Ripmax in January 2007 based on a design by Pete Nicholson
who owned Balsacraft, designed for canned brushed motors & NiCad batteries
so a few mods were required to suit a Brushless motor & LiPos.
Model is now finished and I thought I would share the " assembly" process.

Colin.

More Pics - Trial assembly to check battery location, battery hatch had two
ugly catches so replaced with magnets & brushless motor in place.

More Pics - Battery mount created to suit 4S - 2,200 m.A.h. LiPo ,
E.S.C fitted within cowl to assist cooling & help C of G location,
Plenty of room for radio gear.

Last three pics - Fiddly bits,cowl fitted, cockpit canopy painted & pilot installed, poor chap
lost a lot of his lower body to fit in.

Assembly was spread over several months, just got round to putting it onto the site.

Now awaiting reopening of Cashmoor for the maiden flight, this will be off a dolly as per the "Mustang"

A few statistics on the model:

Wingspan - 48 in, weight - 3ibs, motor Propdrive "35" - 35-36, 910 kv. , Hacker 40 A esc , all servos Hitec HS82MG,
Prop 10 x 6 APC , Current draw 31A from 4S - 2,200 LiPo giving 480 Watts = 160 W/ Ib .
Same set up as my Ripmax "Mustang" which works very well.

Colin, did you not remember the article I wrote (Ripmax Mustang) quite a long time ago on the mods for brushless motors. wimbornemac.org/articles/projects/57-ripmax-mustang-600-ep
Back in 2011. Flippin' hell. Where does time go. Still got that damn Mustang too.

Phil - Thanks for reference - I joined the club in March 2012 so not aware of it.
Interesting to read you later went to 4 cell on your "Mustang".

Yes 4 cells. With three it just flew, with four it flies and I can get probably 10 mins at least with conservative throttles and equal the four stroke glow warbirds in run time But as you know it has acquired some strange characteristics lately.
