I have done almost the same thing to mine Focke Wulf.

Looks good!

I have a few busted up electric retracts sitting here at home looking for a new life, and I haven't installed the retractable tail wheel in mine yet, so might have to look into your idea

Thanks

Well, the retracts work! The right one hits the front well edge and I really don't want to cut into the rib and the balsa block for clearance. And that is with the stock wheels! I have Williams Bros. wheels that are even a 1/4 in. bigger! I'm thinking about putting a very thin ply spacer piece (2mm) under the retract mount on just the front. It wouldn't put the wheels back too far when deployed since the rake is severe to begin with! Ya think?

I had to trim the rear retract rail to get my wheels to fit. It wasn't much, just a few mm. The retract unit now sits at a slight angle.

Mount the flap horns at the same distance from the hinge line.... Most critical aspect of getting the same flap movement. One servo in and one out and yer good to go with a Y harness and set your control arms as close as you can on the servo shaft

Hey guys, which William Bros. Balloon style wheels do I need. There are two types of 5 1/4 inch. Which part number?

Why isn't the wheel concentric with the wheel well? Strut too short or ???

deadstick79

eh Jason,
The wheels are actually 4-1/2" Will Bros. P/N 12100

I had cut the rear rails as Ram, Kaloq and others had done to get the toe-out.

You want the 14500. The balloons work but are fat!!. The 14500 are better looking IMO and fit better. Here is a pic on the TF190. I've yet to get them on the ESM but working on it.

The wheels are the 5-1/4" Williams Bros Balloon style wheels. The wheel opening is much larger than stock at this point.

Don't worry, I removed a lot more material to get the sierras in with the glennis wheels

I think you meant to get RID of the toe out?

Thanks everyone. Ram, those wheels look nice, I'll give them a try on the ESM bird, 14500 it is. I think the thinner profile will help getting them in the well.

I stand corrected!

I used the jump box inflator to fill the retract system! It only shows that it's putting in 71psi and doesn't go higher than that! If I continue, it pops the fill line out of the inflator every time!
I get three solid retracting and deploying cycles. On the fourth one the right retract goes up about 80 percent and then slows down but does finally retract all the way after about 5 seconds.
Is this acceptable behavior?

Not sure what sized tank you are using (I use the large Robart on my planes this size), but I can get around 20 retractions off of 100psi before they quit working. Now, I do not know how many you want to do during a flight, but 3 seems kinda weak. You might want to pump it up and see how many you get after it has sat for a few hours. Then you will know if it is holding pressure.

deadstick79

I have the same Robart tank! My inflator claims it will do 100psi but it isn't so I'm stymied!

Sounds like you need a pump.

deadstick79

Mystery solved!
I was using the "football" needle to fill the system and it would only go to 71 psi. I used the "stock" end used for tires and I was able to get the 100psi and I could see the pressure valve pin extend all the way! I got and easy ten cycles but I don't have all the fitting screw caps on yet either! I think it should work out right now!
Thanks,
Dan

Robart shows only F4U Gear for ESM models. What gear are U using from robart? For about $250 U can convert to electric ...
Solves a lot of problems and they are slower and more real with out all the screwing around with the robart air bleeder valves.
Just a suggestion.

Katniss

Electric gear are not foolproof. They can fail also or refuse to deploy... or whatever else.
I do believe that the gear Deadstick has, he mentioned this a bit ago, that he's got the Sierra retracts but is using robart valves, air lines and air tank. You do not need an air valve with bleeder needles. Robart sells air line restrictors you put in the airlines and those work very well to slow down the retract cycle of the gear. Just a suggestion

deadstick79

Kat is correct!
I do have the Sierras'. I wanted to use the ESM electric Gen3s' but they have been discontinued due to problems I believe they just couldn't solve!
Anywho, the retracts are working great now and I'm able to get 100psi using the tire type filling fitting. I was using the football pin type to fill but it wouldn't fill more than 71psi.
Problem solved!
Just got to slap the motor on put electric gear in and get the CG figured out and she should be ready to maiden ;-)

Dora has been sitting around for some time, and I hope to focus on it and get it done soon! What is the correct color for the gear struts and wheel wells, and where is a good place to buy?

Thanks
