The Showstopper unit is a hollow-shaft system that requires a larger (generally 1.5oz) motor to work. It really isn't suitable for a light-weight indoor model.

Yes, it doesn't work in these planes. The Mamo system is the best one, the lightest and the strongest. RJ, did you see my post on the previous page about the Hacker motor and VPP?

I'm just planning to get one to try out and have fun By the way ain't the A20-34S-EVO is suitable for the Mamo VPP ? Do i need to modify the A10-9L for it ?

Are you running 2S or 3S with the 9" blades ?
No, you have to make the mount yourself but it is not a big job. I have bought my VPP systems from Mamo-Models and Electricwingman.

A10-9L has a 2mm shaft and the Mamo VPP mounting adapters require a 3mm or 3,175mm shaft. I replaced the shaft with a longer steel rod and glued a piece of 3mm carbon fiber tube on the part of the shaft that comes out of the back of the motor. But aluminium tube would be better if you can find one which has 2mm inner diameter.

But I don't recommend to use 10-9L. As I wrote, the performance is not good with VPP. I recommend to use Axi instead. In addition Axi is many grams lighter than Hacker. With this Hacker or Axi 2203 motors and VPP the plane mustn't weigh more than about 150g if you want to have sufficient performance. Hacker 20-series motors are powerfull but very heavy. If it's ok that a plane weighs a lot I would suggest you try A20, but personally I don't like to fly a plane weighing over 150g.

I'm running with 2s.

Wow. Lots of cool guys posting in this thread, and I would like to join 'em.

I dont really have a indoor flying site so my flying would be mostly outside.

Can you use the Hacker A10-9L with the GWS 8 x 4.3 prop on a 3s setup? Say 3s, 500mah? I dont see anything on the Hacker motor listing that talks about 3-cell.

I wouldn't suggest it. 3S on a 9L is probably too much for it to handle. Stick with 2s, it has gobbbbbs of power.

if you want to do 3s on a 10mm hacker check out the 13L http://www.aero-model.com/Hacker-Brushless-A10-13L.aspx I have one I got experimenting with vpp setups but I have not had the time yet.

I have a question for you guys.

What is the purpose of anhedral (negitive-dihedral) on the elevator of some RC planes? I noticed the E-Flite Habu-32 has it, and in the 2008 ETOC event, Jason Noll's biplane has it.

Is it for more stability when inverted? In his free style he does some nice smooth inverted turns.

(starting at 1:34)

It basically modifies the pitch behavior of the plane with rudder input. Essentially, when you apply rudder, it adds down force on the tail, which either causes the nose to pitch up, or counteracts some coupling and keeps the nose from pitching down.

It's not something that would be a benefit on the MX2, which doesn't tend to have any bad tendencies with rudder input.

So cool to get a reply from the actual RC Gritter!!

That's really interesting, I never would have thought of that! I guess i'm ordering my MX2 tonight!

Has FF stopped selling pull-pull for their planes? Went to the site and can't find it. Thanks!

Mike, do you also have the biased servo horn or do those have to be purchased through Radical RC? Which one is the correct one? I thought I heard the smaller one is made to work with the horns you include in the kit? THanks again!

I have each of these not being used and was thinking of giving them a shot. Opinions?

I am thinking the 1800kv would be better? Thanks!
