I test ran the motor on the powerpod...on the table edge

It started to slide forward at 30% throttle.

i dont know if my configurations are rite ....

here are my worries ....and  i really need some help here

At 40 % throttle the powerpod started to move towards left automatically...(looking from behind).....should i be concerned about this.....??? ??? ???

That is due to the torque effect.  
Mount the motor 2 degree down and left. which will cancel the effect.

you can simply do that, by adding 1 washer to the upper side and to the right.

Mada,
This could also be due to vibrations. Even if you build is absolutely square, there might be some vibrations which are causing this. Hold the pod in your hand, away from face, and run the motor.. The prop adapter tip should spin about the same axis. If it's not axis aligned, or the prop is imbalanced, you'll see the tip spread out at high throttle, which is bad.
Rest of the adjustments etc will be better identified once the plane is airborne.

There is no hurry, and no need to jump to any conclusion or do any modification at this stage.

Build your model first. Then see what happens. It is a removable (swappable) pod, you can always do any adjustments afterwards. Don't jump to conclusions.

First build the model

Thank you sanjay sir, girish sir and swizera sir for your valuable comments. :bow:

i will the complete model then make the adjustments

with RCI support I surely belive that my model will be airbourn soon :)

If they are are nylon props, they are very weak and my change pitch while spinning. also they don't stand a nose impact. go for some Slow fly type props and something strong.

Best of luck.

This is just my personal opinion as i found the nylon ones crash almost every launch.
I have this one, a SF and JXF prop. JXF is a bit heavy but awesome strength.

and it survives a lot.
and yours is a tractor type, so a stronger prop is must as you are very likely to break a prop every crash.

If you motor permits 8.6 prop, go with this one.

they are slightly heavy, but very strong. can take hard impact.

I asked a question Flitetest forum and the guys replied with saying go for the Ft Flyer and then build FT Nutball as the flyer is easy to fly than a nutball

Your control throws will be very high as you have fixed the horns very close to the hinge. Be careful

DAY  6 UPDATE:

The landing gear is made from black foam ...3 inches ( known locally.....its like light weight rubber foam).
weight of wheels with 1.8mm spring steel wire....40 grams.  pic 1

i guess the landing gear is overkill..... i just hope the landing gear is too bulky...


Did not fix it to the power pod yet.....need  to search BBQ skewers and Velcro . or will use zip ties with internal reinforcement.

Temporarily attached using simple rubber band. pic 2 & 3

Power pod with landing gear weighs 158.5 grams....pic 4

plz comment senior members...
