F-14 Tomcat EDF work in progress 2

This by far takes the longest build for any of my model. Let's continue..

Wing swept mechanism..I'm using MG955 (0.17s/13kg torque). I know some may say this is one crappy servo but so far I have no problem with centering or overshoot. It just work fine. I've tested like hundreds of time before gluing this servo to the bay.

Pretty simple setup for the swept wing just be sure to stiffen up a bit the pushrod with some CF tube. The wing spar is the most important part for this plane. Since the spar is quite flexy, I reinforce with some plywood at the center of the frame. Now much stronger and less flex..








Dry fit. Will further test the wing retract servo before any gluing.

Only one pilot..it's pricey..I paid almost 6 bucks for this..


note: Make sure no play or wobble with the taileron. This jet basically fly with this full swing taileron. Fiberglass this part to make it durable.

F-14 Tomcat EDF work in progress

I'm now working on my F-14 tomcat. This baby takes a lot of patient and time to work with. The longest I think so far I spend my time on it.

I start with glassing (elevator, vertical stabilizer, duct area, and nose cone) all the critical parts, then enlarging ducted area to fit in 64mm fan, wiring, soldering, and a lot of test fit just to make sure nothing goes wrong. Test run both motor's and ESC's both connected together and share the same lipo. Everything seems to be OK. But will do stress test to the motor before fitting the back side.



ESC area need more space so enlarge the ESC area.




Waiting for servoless retract from HK.

Trex 500 Nitro Conversion

Finally my dream of having 500 nitro conversion come true..courtesy from bro Ishak (aka hakulhak MRC)..thanks bro...

Installation manual can be found here.

A few tips.

1. If you're using 13T pinion..make a slider hole to the main engine mount so that the pinion can hold on to the main gear.
2. Wiring a bit messy and require proper planning. So plan ahead.




Messy wiring..



I'm using the worn out fan shroud. Repaired with fiber cloth.
