Hi,

Our full size Enforcer flys on a Hacker B50-13XL in a Midi Fan Pro on 8S. It flys very well but has fixed gear which limits the top speed.

The new Enforcer is scaled down 10%, has Spring Air retracts, and will take interchangable 70MM or 90MM power pods.

It it flys anywhere near as good as the Spatha, I will be very pleased.....

Spring Air, very disapointing.

I need to vent
Spring Air retracts are some of the finest made products that you can buy for your model. Reliable, strong, and made in the USA. Not to mention the value is great. For the same price as "just the retracts" of another brand, you can get the whole shabang, tubes, valves, T's, tank, everything from Spring Air.

But, (you know there had to be a butt) the web site is terrable. Missing informaiton and misleading information. No drawings for the 600 series. How much do the retracts weigh? Drawings that are present are very misleading. One drawing says the 200 is 1 1/8" deep. Then the drawing on the left says 1/8" down (you mean up?) and points to the trunnion. So are they 1.125" or 1.25"? And its very difficult to distinguish the difference between the 100 and 200 series. And how about some nose gear dimensions? They show a weight limit for the 100 series but not the 200, or 600. And the 700 are bored out... but what size? Bored out 200s or 600s?

No notification or indication of stock status. If the retracts are made to order or they are not currently in stock then say so! Preferably on the website or during the checkout process. At the very least email me the status when you confirm payment. It's nerve racking to paypal someone $160+ and not got a product nor an email notification of the situation within a week or two, or in my case 4 weeks after I email them!

So now I have a set or retracts that are 1/8" too deep. Dad say's he can mod the wing (ya, its already started, just no photos yet) to fit them. But thats not the point.

Sad really. I really like their products....

Well, I just tried to assemble my gear and they sent me the wrong sleeves. They sent me 5/32" not 3/16... aaahhh!

Wing

Here is the wing being contructed in Dad's non traditional way. I built the wings on both of my scratch builds this way and had great results. No jigs, no bars. Just a nice flat piece of wood. Lay the spar down flat. Glue the root rib in at the propper angle, the glue in the tip rib. Span the trailing edgle across the root and tip ribs. Now all you have to do is fill in the gaps with the remaining ribs.

MH-43 airfoil.

Wing Continued

More progress on the wing. Its going to be sheeted in 3/32" balsa for extra strength. After some discusion we decided that a sharp pull up or turn at 160+mph could create 10 G's of force on the Jet. 10.5lbs x 10 = 105lbs. Thats a lot of weight for some balsa wings to support. Better make it strong. However, I am a little nervouse about the weight, but he assure's me that it will be within its weight limits.

The wing was built with no dihedral. However, the wing tapers up (top is flat) this gives us the same effect as a small amount of dihedral. Besides that, sweeping a wings give the same effect as dihedral.

In the pictures you may notice a slight change in the airfoil where the wheels tuck in. This tiny "bump" will ensure that the wheels tuck in nicely without the need for expensive or custom made ultra thin wheels.
The tubes you see are paper servo wire tubes.

I choose Xtreme Power Systems

Ok, I ordered 3x 4S1P 5000mah 30c battery packs along with a 2s 1100mah A123 reciever pack.

Here's why I choose XPS over HobbyCity:

Weight They claim to be 32grams less than the Turnigy 5000s. That's over 3oz of savings with all of them together!

Cycles I've also been doing some reading and have found that the XPS batteries typicaly last at least 2x longer before significant performance loss. The Turnigy's are about 1/2 the price, but once you pay for shipping they're about 2/3rds the price. So if the XPS's really do last 2x as long, they'll have paid for themselves.

Service I've heard that HC can be hard to deal with at times. But I've delt with XPS at the Arizona Electric Fest and they presented them selves in a friendly, knowledgeable, confident and helpful manner.

Hope I made to right choice!

-Joshua

Hi Joshua,

A made a comparison list for xps and Hyperion cells in a thread of mine and the xps are by far a better choice

post 25+26

Pack_cap_cap.85_Cd/Cb_M_M1s_M4s_M8s_M12s_(cap.85/M1s)_$_$1s_Eur_Eur+19%_Eur1s_Eur4s_Eur8s_Eur12s_S+ H

If you read the numbers patiently you may do this for your own setup as well.
My bad luck is that the 3s1p 2500mAh cells are not available anymore. I really fancied a 12s setup myself.
