Pigi vs. newer 3D planes

I've been out of the hobby for a while now but have finally finished some planes I bought a couple of years ago. One of the planes I finished and started flying is the Pigi from Hobby Lobby.

I've read through all the posts on the Pigi but most of them are from a while back. I've got it flying OK but I'm getting pretty short flight times out of my lipo batteries. With a TP 3C 2100mah lipo I only get about 5 minutes flying at half throttle. With an older Irate 3C 2600mah lipo I get maybe 7 minutes.

My question is are those normal flying times for the Pigi setup? I've got the PJS 3D 1000, Jeti 30-3P, HS-55 servos, Hitec 555 receiver, and the lipos I mentioned.

With the flying times so short with decent batteries I'm tempted just to retire the plane and get a newer foamy like the E-flite Yak. The Pigi is a big airplane with lots of amp draw and would seem to require a big expensive battery to get decent flight times. Maybe the new planes are just such an improvement it doesn't make sense to invest more in this plane?

Just wanted to hear some opinions on the Pigi vs. the newer and lighter planes like the E-flite Yak or even the Extemeflight Yak.

You say 3c, did you mean 3 cell or is that the c rating of the batteries.

If they are 3 c batteries you could well be exceeding their ability.

Your motor can use about 25 amps. If you are running in the 12-15 amp range on average they battery useage isn't that far off.

I'm sure you will get some better answers.

Good Luck,
Lyle

Thanks Lyle. I meant the batteries are 3 cell. The c rating on the TP is 12 and on the Irate I'm not sure but I guess about 8 to 10c. I know others have recommended these batteries for this plane but it just seems maybe a newer lighter plane may be the way to go.

I don't know if buying a new 3s2p just for this plane makes sense when the trend seems to be using batteries in the 3s 1350mah to 2100mah range.

I would go with something in the 2000-3000 mah range. I had a 3S2P 1500 (3000 together) setup which was good. I now run a Kokam 2000 3S 15C lipo. You are holding back the beast with the plane. :-D

Jeff,
I wouldn't hestitate to recommend a Tanic Pack 3s2480 rated and 37.2 amps.

If you really push this plane you should get close to 10 minutes flights. But in my experience my amp useage really isn't close to that and you might even do better. You would have the punch when you needed it.

Have you ever checked your amps static at full throttle (with prop of course)?

Good Luck,
LcJ

I have the PJS 1200 on my Pigi and fly it with two 1250 3P Kokams. These are not the best battery but I have them and I get over 10 minutes with them. I have increased the size and have massive throws on all control surfaces. The reason I keep this plane in my fleet is it is a great training tool that a beginner can fly with a buddy box. The plane is very slow and predictible. It is the only plane I own my 12 year old daughter likes to fly. My other planes react to fast for her.
