Guys, can anyone share what they use as a test stand to start and run their MOKIs on the ground? Also, does anyone have a source for an aluminum spinner about 4" in diameter for a 2 and a 3 bladed prop? TruTurn used to make them, but no longer making hobby products.

Any help will be appreciated,
Larry Fitch

try aeroscale in Australia for a spinner, he can make any type you want.

Planenuttz, Thanks for the recommendation. I'll contact them.

Hello to the group.
I need some advice on my Moki 180. I run a prop 28x16 as airworld suggested but my model flies like a F16 and it is difficult to come on the approach. I always overshoot the runway.
The model is a Spartan executive 1/4 24,5Kg.
I have tried a Fiala 30x12 on the ground which pulls less especially on the low revs but the motor has gained up to 1000revs at full throttle thus 5500 which i know it is not good.
Can i try the 30x12 on the air?

How can i limit the revs on full throttle? Is it ok to limit the throttle servo throw?

As a note, i have to say that i am not so experienced in big warbird models. I struggle to follow what i see on youtube, to do a very shallow approach with steep decent which apparently slows the model down. I tend to fly further away and try to fly the model to the runway which means extra speed to keep it airborne.
Probably from my stress not to stall the model because of the work i have put in it.

Many thanks in advance for the advice.

I'm wondering about the plus and minus of continuing to leave the stock pneumatic air pump hooked up to the carb while I also use the ASP pump. I can't really think of much of a reason not to. Might make starting easier. What is the consensus on this?

There is no reason to disconnect the stock air pump. As a matter of fact, it could act as a back-up pump should your electric ASP fail.

Richard / Mitch,

I do not think the pulse pump will affect the operation when the electric pump is working.

If it is a good Backup?

I dont know.

But I could imagine if you do not care any more about grease in the tube or else ( you will not know if the performance of the pulse pump decreases as the e-pump is much stronger) , then the electric pump fails one sunny day, the carb is adjusted to the higher pressure of the e-pump, does the weak natural Moki pulse pump really bring you home?

No idea. Maybe better than nothing. Could depend on the way ( and situation) when and how the e-Pump quits.



On the other hand, it probably won't do any harm to have the pulse pump still fitted. But the feeling of security could be deceptive.

Simple first attempt: do it this way and simply switch off the electric pump (on the ground)
