50cc Yak 54 2.2m

[hannustar]

hi all guys,
i have on the way a new yak 54 2.2m,50cc.It is from fly model or better known from nitro planes.I will be putting a DLE 55cc and DS8411 all around and i thing that i will put 2 on the rudder as well.Know i would like to know what about the power plant?any ideas?and as well some help on this plane,some fly's it?have one?C.G.,ecc ecc.I will fly it with JR 2.4,(9X).This kit look good,push rods already cut and ball links are already mounted on the push rods.

Thanks for any help

DLE 55 is good... not sdure how much torque a 8411 puts out so i shan't comment on that... but as for the engine... u will be fine....

[hannustar]

10qs.a guy at the field had 8411's on an extra 100cc from composite arf and never gave him trouble so i thing i am fine.2 days ago my yak arrived and all i can say is woow.i already began some work on it like elevoators,rudders.......but i have a problem on the rudder.i installed 2 8411's on the rudder and i allready connected them but the question is,to the rx do i connect them with a y lead or one in the rudd chennel and the other is a sperate channel?

[fonzegator]

in all honesty i would go with one servo but when i did a ganged rudder setup i just used a y-harness but i made sure the servos were in the same direction... u dont want them working against each other... u can also use a servo reversor...just my 2cents worth

[hannustar]

I tried the rudder servos together with a y lead and they are fine but now im getting a heavy duty one.i have to do a shopping list.i will change the wing tube and the landing gear so it becomes lighter and some of the hardwear.i hope i will finish it soon.

Nice Flying.... !.. i think u will find that the bigger the planes..the better they fly....soon i guess u willbe postiung a build thread for a 35% and then a 40%....

[hannustar]

yea,i hope they fly better.ectually i have an extra 100cc but i prefered that my 1'st gas airplane would be smaller than a 100cc so that's why i got the yak.now i will get some experience on the yak and then it's time for a 100cc oneall i can say about the extra is that it's huge.without the cowl and the rudder it's long as the yak 50cc with the cowl and rudder mountedi hope i wil finish it this year

[fonzegator]

yup... but 35% need more higer end stuff invested like servos and batts and such... so enjoy ur 50cc first!..

[hannustar]

yes i know that.i already have a 3W 100i and the powerbox so the costs left are the servos and batt's hehe

[hannustar]

guys, what do thing of these 2 power setup's on my yak?

2x "2150mah 2 cell 7.4 volt pack, Duralite" For Rx
1x "Smart Fly, Turbo Reg or Super Reg" For Rx
1x "2300mah 2S1P 6.6 High Voltage pack, Duralite" For Ignition

or

2x "A123, 2300mah 2S1P 6.6 High Voltage pack, Duralite" For Rx
1x "A123, 2300mah 2S1P 6.6 High Voltage pack, Duralite" For Ignition

Any other Ideas?

this plane has an issue. its tail heavy and this is not funny.

Anyway, I wish you luck!

[hannustar]

thanks for your advice.that's some bad news.there is another thread on this one and they never mentioned tail heavy or a bit if they did.but i know it comes out a bit heavy so i am getting some cf parts and reduce some parts as wellhope i go well.

I have also one, and I'm was not able to balance the plane(with 55DLE).
Now, Im still working on the tail. I removed 260g from the tail and I expect to put back 80g, so this means something around of 300-400g extra weight its not anymore necessary on the front... The estimated weight its around of 8.1Kg.
