How do you guys give toe in? Twist the rod below the spring or modify the slot where the screw is?
Something has to be wrong here, yes i can put the spar first in the stab and then put the stab in the fuse but look at this pic that dont align either, anyone please thanks for the help

In my kit, in order the stab to fit, the spar couldn't go all the way into the stab.
The gluing process was made inserting the spar into stab -> stab into fuse -> adjust the spar into screw holes while holding the stab so the spar could move and adjust.

Maxman i rehaped the carbon spar. Enlarged the hole in the fuse for the carbon pins as needed. Then i sanded the fuse where the stab root mates an glued the stabs in place using a quality thickend epoxy. The model flies better. ill post a photo.

Thanks to all for the help, whisperdancer your steps worked perfect thanks i just finished, now to continue the build.


I will install today the retracts, what type and size of screws should i get? i have read that the provided screws snap. thanks

Use the same size screws, but you can find better quality ones at ACE hardware or a similar store. Also I recommend using a small amount of dish soap as a lubricator for the scews. Another tip is to work the 4 screws in evenly as you go, this minimizes the chance one will snap. Go slowly and take your time. This was the most frustrating part of the whole build for me. I spent alot of time trying to get out broken screws!!

Recently I bought a FOD for my P20 Habu...



I was at my buddies place last night doing some build on his new Habu and we took a look at the FOD close up, compared to the DeltaV 80mm it turns out the P20 is actually pretty small!





I wonder could you squeeze a bigger turbine in the Habu 32?

I used #4 x 5/8" Phillips flat head wood screws.

Also, drill the pilot holes to a larger dia, so that such excessive torque is not required.

Indeed it is.. Abgasgeschwindigkeit (km/h) 1674 <----- Exhaust gas speed.

Translation.. ---> emission gas velocity of a P-20 at full throttle is 1040 mph.

The speed of sound is... 768 mph.

Chalk that up to pure awesomness folks. All this, at 245,000 rpm. Heck yes, mate.

Don't forget about how awesome the smell and sound of a turbine is too.

all this may be true but the p20 will never be as fast as a 9,10,11,12s edf the p20 in this airframe is 150mph and you can just about get their on 8s edf

Specs on the Wren44:
Thrust : 45N / 4.5kg / 10lbs
Weight : 600g / 21oz
Overall Size : 215mm x 75mm (8.5" x 3")
Ancillaries weight (inc battery) : 340g / 12oz
Max RPM : 195,000
Idle RPM : 55,000
Idle Thrust : 1.5N / 0.15kg / 0.3lbs
Fuel Consumption @ max thrust : 176ml per minute / 5.8oz per minute

The Overall diameter is still smaller than the Eflite Delta V 80mm so it could be made to physically fit. It is double the weight of the P20 though, given there's already weights in the nose of my P20 Habu I guess the whole plane would become pretty much a speeding bullet. Still 10lbs of turbine thrust in the Habu would be epic to watch

After reading the MAAA rules about certifying all turbines, any chance of one soiling my car has been relegated to the can.
