Hobbyking Pitts Special EPO

It very intresting thread. FusionTiger is genius.

Yep, flew it for barely a second.

It was my error that I did not brought my neckstrap and I was not fast enough to throw the Pitts and get back onto the stick in time which resulted in a fatal crash.

However, just recently I had finished rebuilding the Pitts and my mate gave me his Pitts. So, I could be giving them some flight soon.

Originally posted by msgt81 I have bought this Pitts from Hk and it appears to be slightly different from yours.It is aHK Pitts special plug and fly/ 4aileron version. I'm sorry to hear that you are having probs with your. http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idProduct=14881  this is in the US w/h.  The HK version is product=10102 this plane flew well after trimming. it came with a DAT 700 mtr.and20 amp esc and has plenty of power.  There must be 2 versions at HK.  There are 2 screws approx.23 mm overall length X 2 mm diameter with a black knurled knob on the end. Do you have any idea what they are for? As there were no directions with the plane, I can't figure out what they are used for.

Different plane mate, this thread is for the smaller 'EPO' variant. ;)

Oh its ok msgt81, all is good.

Well it has been a year!!! So, my mate gave up on getting the 'flight-incapable' EPO pitts and gave it to me in hopes that I might get it repaired, modified and soar. And soar it did!

Setup:
Motor - Stock
ESC - Stock
LiPo -  Turnigy 30C 1000mah 3S
RX - FrSky 4ch
CG - From Upper wing leading edge: 60%
Prop - Stock 7x5(Failed), MasterAirScrew 7x4(Failed), GWS 8x4(Failed), GWS 8x6 (SUCCESS!)

Modifications:
1. "Battery Cage" removed and replaced with velcro-mounting.
2. Landing gear stabliser mod.
3. Extra aileron throws via lever shortening mod. EPA 50%(Casual flight) EPA 100%(Extremely twitchy but suitable for crazy stunt manuvers)
4. Tape-hinges for elevators (Stock EPO-hinges tore)

Amp draw is not yet measured but the motor was scorching after only about 2mins flight.

Conclusion: It flies on stock! but only with a GWS 8x6 prop which is too much for the stock motor to handle sustained flight. Definitely a need to swap for a more suitable power system to get it into the air properly. However, I'm guessing that the newer batches of the EPO Pitts comes with a more suitable stock motor setup (Please ask HobbyKing for confirmation).

You mean the blue ArtTech EPS Pitts? That was not my goal, I wanted to give EPO a try and I wanted something smaller.

It was not a torture for me and not much time was wasted to deal with it. It's all part of the fun and experience.

"From failing, you learn! From success, hmm... not so much~"

your work here is done it flew for 30sec now put a match to it
