Pilot RC yak 54 87" 50 cc "Millie G" Slow build
Purchased a new Pilot RC "Millie G" 30% 87" Yak 54 from the Chief Aircraft tent at Joe Nall. Due to money constraints (and being new to giant scale), this is going to be a slow and painful build.
I've got a couple experienced builders/pilots that have agreed to help with the build so I'm fairly confident we can get it together pretty well but I'm open to any advice I can get. So far Ive got the plane http://www.chiefaircraft.com/prc-yak30-mg.html And a yellow power board from Redwing RC http://www.redwingrc.com/Power-Board-PRO-SERIES-Yellow-4105/ that I intend to power with two 3 cell lipo batteries or 3 cell life's (if I can find them at a reasonable price) Once my wallet cools off I'll start purchasing other items. For servo's I'm thinking either Savox SC-0251 http://www.amazon.com/Savox-SC-0251-.../dp/B004K3EZW2 Is the "larger than standard" going to be a problem? Will the slower speed of the 251's cause an issue? Hitec 5645 http://www3.towerhobbies.com/cgi-bin...P?I=LXUZ80&P=8 Will the lower torque and speed be a problem?(the online manual calls for a minimum of 180 oz's) XQ 4020 http://www.redwingrc.com/XQ-4020-digital-6v/ Good specs but no one at my field has any experience with them. These are at the top end of what I'm willing to spend but I'm not sure of their reliability For engines I'm looking at DLE 55RA http://www3.towerhobbies.com/cgi-bin...?&I=LXCPZD&P=0 Will this be plenty of power? The firewall of the Yak is already marked for the 55 and I like not having to carve up the cowl too much. DLE 61 http://www3.towerhobbies.com/cgi-bin...?&I=LXEBGM&P=0 Only $30 more than the 55 RA but fit with the stock muffler maybe an issue BE 62 http://www.valleyviewrc.com/estore/be-62cc-engine.html A little more than the 55 RA (after Tower discount) but definetly looks interesting Thanks for reading and any advice will be appreciated Eric P.S. I'll try to get some pics a little later. The covering and scheme are really nice |

My Yak rebuild story at RCGroups might help you. Used very similar setup and at least you can check where I placed the power board...
My Yak uses HS-5955TG / HS-7955TG and it's currently using cheap RCG 55cc engine. Original DA-50 is being maintained. I just came from flying and RCG 55cc gave nice power, couldn't ask for much more... 60cc+ engines will give really good performance! |

Stangflyer, thanks for the advice. I just ordered the DLE 55 RA from Tower, (just came back in stock, easy pay's a real life-saver). dusturbd, thanks for that. I'm really leaning toward the 251's and should be able to order them in a couple weeks. Thanks to eveyone for all the great advice. I really appreciate it ![]() Crap, just noticed I put the wings on upside down when I mocked it up in the photos ![]() |

I'm using two 2S 2200mAh LiPos. Didn't even consider 3S, for some reason it didn't come to my mind that I could have used them... And I also had those 2S LiPos left from the crashed setup.
![]() There's plenty of clearance to rudder servo & pull-pull. I can check tomorrow for exact amount, but I would say that at least an inch... I just used the rubber gaskets & screws that came with power board to attach it. And of course glued & screwed those wood pieces it is attached to. So far everything ok. I can take more detailed pics tomorrow... |

On a side note, I went ahead and ordered the Savox 0251's today straight off the Savox (or whatever the new distributor site is). They had them for $20, which is $15 cheaper than anywhere else I'd seen + free shipping on the 5 I ordered |
