I never made any plans for an EPP PBF. But a PBF isn't exactly rocket science, so here's some photos of an 18x18 EPP PBF that I've been using in combat at the probro events for the past year. These photos should be enough information to get you started. Then if you have specific questions, we can figure that out as we go.
Hopefully the photos can be enlarged so you can zoom in on the details.
Well, I get that sentiment.
Until you've smoked everyone in the pits it's no fun. The smell of castor in the morning, ahhhhhh.
Seriously tho, if you've seen and flown Mike's (aka ThumbSkull) e-pbf you've seen the best Ive flown.
I need to get out to Eldon or one of the tour stops next year. Remember when we did those Pro Bro Tour shirts? I'm getting old.
WELL,what can i say,got nitro in my blood. Started a pbf. got cut out,spine and mounts on. Dug some 72 gear up,and servos,will try to post some pics later. Plus, that fp 40 been waiting to long for a home.
Plug, the goal should be to end up no heavier than 2 lbs, 8 oz. Once you exceed the 2 1/2 pound mark, the PBF starts feeling like an overpowered slug instead of a super maneuverable overpowered feather. That's also the reason a 2 pound bushing 25 powered PBF is so much fun to fly.
I just weighed a JR 507 servo without the servo arm and it weighs 1.6 ounces. So with four servos in a PBF, that adds up to nearly a full 1 1/2 ounces heavier than four Futaba 3003.
A 700 life battery is plenty big enough, and only weighs about 1.25 ounces.
A typical 2.4 receiver should weigh about 1/2 ounce.
An empty 4 ounce fuel tank should weigh about 1 ounce.
Don't use a switch. Just plug the battery directly into the receiver.
Don't fill up the fuel tank. About 2 or 3 ounces of fuel is plenty for a lazy 10 minute flight at a low throttle setting.
So getting a PBF with a 40FP down to about 2 pounds, and 6 or 7 ounces isn't very difficult.
What Hitec servo do you have? The HS-82BB or HS-85BB should work OK, and the ones I just weighed were .7 ounces each. The metal gear versions would be a better choice and only add a little more weight.
Just a pic of the red devil,33oz there,i used some smaller servos so 32oz plus prop and tank. So be under 2.8lp when done,if i dont muck it up. Pine center,hardwood mounts all lightly glued to board with screws. Thanks McDDD for leading the way.
