Park 250 for a Tensor?

[exeter_acres]

Curious if anyone thinks a Park 250 (or a 2204/54 for that matter) would be enough for a Tensor?

I have used 2208/34's on a Tensor in the past, but would love to see if the new Park 250 would work on it now?

Thoughts?

The park 250 will be to small. I think that a 2204 on 3 cells will work great. Just make sure you move everything forward as it will be really tail heavy.

How do you guys figure this out.?!

I usually have a foamy that is too heavy due to too big of a motor.

Then I goto a contest and see all you pro's flying planes with a tiny motor on the front with a plane that weighs 7oz wet.

I finally have a pretty nice foamy with the park 300 on a 700mah 3 cellm or a 500mah 3 cell, but how do you figure out whats enough?

ummm, they are 5.6 ounces wet

[bosshoss]

the 2204/54 jeti 4amp , and 480 or 730 TP 3cell.

IF and I say IF, you want to really make the Tensor a better, more airplane like foamie, rather than the Box-kite that it is:

Remove 28mm from the bottom cabane and 28 mm from the wing strut foam, making it more Ultimate, Biplane-ish. Leave off the SFG's on top and bottom also. It will fly like it is on rails.

Instead of one criss-cross in all the CF rods ., you will end up with three crosses in a triangle. no biggie and it looks like art.

I was skeptical unti lI tried it, and it rocks. better than the E-flite Ultimate.

Sleepy,

On finding a new motor I try and build the plane around that setup. For the Park 250 I have shot for a 4-5 oz airplane and it will have plenty of power. Anything over that it will not be good. For the park 300 you could go from 5-9oz depending on battery cell count. There are so many different motors out there its hard to figure what you need.

It took many years to try and figure all this out.

Kewl...thanks

Missed ya last night Andrew... as always it was fun! At least Beer is cheap at the hall!

Hmmm.... now to decide what airframe for the Park 250....

[Animal Jesky]

Yea I bet the meeting was fun but probably not as fun as an english final!!! As for a plane look at a shockflyer. Either the orginal or V2 versions. I think you could make these 4-5 oz with no problem.

Andrew, I have always wanted a 5oz Shockie....Edge,Extra , Superstar,...Sup preferably.

What gear have you used for one that gets under 5oz? 4.3 g servos? Axi 2204/54 or CDrom motor? 480 3cell ?

Obviously the lightest rx ..7g for the AR6 Spektrum, or a microstamp,

I have gotten close, ...relatively, 6.8 ozs...but with some cheating..

[exeter_acres]

I have the Yak shocky that I just finished this morning... used my 2204/54

came in right at 6oz

I would love to pick up the F3a or something similar.........

Boss,

On my plane, I have the park 250, hacker master 4 speed control or cc10 amp, I actually use the Eflite S60 servos and take the bottom case off and drill through the servo output shaft and run carbon rod through for the control horn.

And for battery the polyquest 300 2 cell works great. This setup will give you sub 5 oz.

O forgot about receiver. I use the microstamp for 72 mhz and the new ar 6100 for spectrum.

My Yak Shokie is 5.8 with a 3 cell 720 Thunder power. Here is what I did.

Servos - 3 BlueBird 3.8 gram servos
Reciever - GWS 4 channel
Speed Controler - Thunderbird 9
Motor - CDROM from RobotBirds

Leave the extra gear support off and leave the CF off the wing (the one between the wing and ailerons)

If you want some pics I will post some.

The lighter they are the less carbon needed. The problem I found with any bluebird servo is they are horrible at centering and resolution. The S60 can be lightened to 4 grams and center awesome and resolve great.

I just saw the spektrum 6100 rx 3.5 grams wow! Its almost enough to get the DX7 just for foamy.

AJ Lets see these mods to the s60 you have done.

When I get home I will post the pics.
