Possibly a terrible idea

I really like what you have done, the change from electric to glow. His model works wonders.
Could you please comment, what servos do you use and what battery on board?
Thank you very much, I congratulate you!

Two cheap 5g servos (Tower Pro or some other generic (off-)brand), a 120mAh 2s LiPo battery and I use my "3 diodes in series" voltage regulator to drop the battery voltage by approx. 2V before feeding it into the receiver.

Aircraft companies (in fact, all engineering companies) use their know-how to reduce development time and risk, which results in similarities between aircraft. Look at the Seversky P-35, Republic P-43 Lancer and Republic P-47 Thunderbolt - their wings have the same shape (and, less obviously, airfoil. Note: Seversky and Republic are the same company). Even today, all the Boeing airliners have the same nose shape, and all the Airbus airliners have the same nose shape, that's different from the Boeing one.

This doesn't necessarily mean companies just take an existing airframe and shove, a more powerful engine on it and call it a new type of airplane (well, they sometime also do that as well ). Look at these three 1930s Polish fighters:
https://en.wikipedia.org/wiki/PZL_P.7
https://en.wikipedia.org/wiki/PZL_P.11
https://en.wikipedia.org/wiki/PZL_P.24
Wikipedia (incorrectly) calls the P.24 a "variant" of the P.11, and if you look at them you may think "oh yeah, they just put a different engine, covered the canopy, added wheel fairings, job done", but in fact, only 30% of the P.11 parts were reused on the P.24. In fact, the latter has an entire new wing designed from scratch, even though it looks identical to the P.11 wing to the naked eye. Further still, virtually no parts of the P.7 were reused on the P.11.

How much of the P-36 was actually reused on the P-40 - I don't know, I wouldn't trust Wikipedia on this unless there's a good source quoted.

Thanks for answering.
You tell me that you use a BEC then, or that your own voltage regulator is manufactured?
In my case I use a direct battery of 3.7 volts and 250 mha, and I carry 3 Turnigy 1440 micro servos, Ailerons, motor and depth, (no steering wheel), that allows me two flights of about 8 minutes each safely, then of that I have to recharge the battery.
The RX below 3.5 volts are reset, therefore I am interested to know if your regulator is manufactured by you or is a commercial voltage regulator. From already thank you very much.
Due to the speed and effort that the servos do, this model of the small ones that I have is the one that consumes the most battery in flight.
Here is a video of my model of which I speak, greetings:

I literally just use two (or three, depending on the receiver's rated voltage) 1N4007 silicone diodes in series with a JST plug on one side and a servo plug on the other. Each diode provides around 0.7V voltage drop, so for example 3 diodes drop the voltage from 8V to 5.9V.
I described this method on this forum years and years ago, and for the life of me I can't find the topic now.

Thank you very much for that information, that is, you can make your own voltage regulator according to your needs.
I will consider this data. Thank you!!...

BTW, I also used a home-made regulator based on the TL7805. That works ok, providing 5V@1A, but the weight is comparable to a cheap 6AMP brushless ESC, a bunch of which I happen to have laying around. I can use the BEC of an ESC like for notro flying. I'm not sure it provides continuous 1A though, but it seems to work alright for small models.
