I am trying to build a Guillows Dauntless with a 31" wing span. I have searched all of the messages for relevant info and have come up with several previous suggestions on engines and batteries.

Problem is I dont have the foggiest of what any of this means. I have built many guillows, but have never tried making an RC version. I have a new futaba 2 channel R/C with servos and such. I am also wondering if I can run the servos off the motors battery, or should I keep the bundle of batteries that came with the controller?

Here are the acronyms I need help with as well....

I found help on converting rubber to rc in the free articles on rc microflight magazines site. They did a 30" dumas bearcat. I' m currently working on a Guillows 3/4" scale (27 5/8" span) Spitfire.
Rudder, elev and ailerons. Speed 280 geared. I hope it flys, i'm going as light as I can, punching hole in ribs, possibnly tissue. hoping all up she'll be around 12 OZ. Go lithium! but research first..Ebay has guys selling converted lions and chargers that he has tested and has no probs with.



Speed 400, size mtrs.would be ideal. The added wt. would allow You to fly in some wind, like My old slimers did. 7-500ar or 7-600ae would do the trick. My heaviest cat was 32oz, w/a then micro- radio of 6oz. Flew for two yrs. Good luck, the design is on your side.

I am flying a Guillow's PT17 with GWS EPS300C geardrive, GWS 9X7prop,8-cell 720mahAAA pack Hitec 555 and 2-HS-55 servos,Pixie14 esc. I beefed up wings and added dihedral, top wing is at zero incidence. Total weight 17.4oz. ROG take-offs, 10 minute max duration at average 3/4 throttle. I think that the above power system would be about right compromise of power versus weight for the Dauntless, Hellcat, etc. I plan to use the above for my Dauntless kit. You could use a lighter 300mah 8-cell Nimh pack for 5-minute flights.
