Turk1,

Good video and one Great thing I noticed in your first video, before you flipped the prop, you said Bismillahir Rahmanir Raheem.

Mody

Thank you all! Let me explain and introduce NGH GT35 engine as details below, it is useful for you to know GT35 structure and use it.

Special design on GT35 and it is unique.

1. Glow style vision: (with all NGH size)

a) same dimension as classical .180 glow engine size with beam-mounting, you can easy to replace GT35 on your airframe, also the extra rear-standoff for your preference for installation.

b) Sleeve made by special wear-resisting material with long life (with all NGH size), this material is with special ring material and will work together for long life.

c) Sleeve with high precision (with all NGH size):  strictly control for tolerance within 0.003mm, usually made by plated just be 0.025mm in China,  this tolerance is very important data on an engine, high precision can keep the high RPM for long time, because when the engine is with break-in and run for any time, at the beginning always engines are with high RPM and powerful, but this situation can’t be last long time, because the engine running has a wastage on the tolerance, this is why always we use a new gas engine with high RPM and powerful at beginning, but it is less power when it works for a short time.

d) Intake from crankshaft with front carb: let the engine is more compact.

E) Always use glow-type Muffler: with less noise than Polished-muffler, but maybe some leak same as glow engine, and some can be rotated with 180 degrees.

F) almost all parts are separated as same as glow engine, we can easy to assemble it and disassemble it, and no need to make the crankshaft with rod as a part, use a Roller-bearings Conrod made by aluminium alloy.

2. Special converting structure:

GT35 is with three parts separated, cylinder-head, cylinder-block, crankcase, each GT35 has an extra piston inside the box for converting to side-exhaust or rear-exhaust, we can convert it home, just rotate the cylinder-head and block and liner with 90 degrees together, and replace the extra piston assembly, it is from side-exhaust to rear or from rear to side.

As a real engine manufactory, always we need get some steps;

The first is size-selection: we always got suggestions from market and dealers and model friends and many people even we do not know each other, because many good suggestions had been considered to match the design. We did our best to match all into one size-selection. And then we make it.

Process of manufacture: always we met problems, and we keep the discussing with many people to solve it with no secrets.

Process of test: each new always be tested by many professional experts and my flyers, modify…..

Share the fruit: let us see and use it which made by all professional advice from yours all.

All helps to me to make some different products not just copy and to be a clone. Really thanks!

Sir.

I think you bought a GT35 which is with side-exhaust, the converting is easy, please try to do carefully.
1. research the GT35 with the manual and explorded views.
2. disassemble your GT35, remember the situations of some parts which need to change.
3. take the Ring installed on the extra Rear-pinston, and inside the cyliner-liner
4. rotate the cylinder-head and cylinder-liner with 90 degrees.
5. reassemble it. it is GT35R with rear-exhaust.
6. please do it carfully and think it with all parts are correct situations.

NGH gas engine is with classical glow engine style, each size is with sleeve inside for long time works, so All NGH gas engine is any more heavy than others which many by plated-head gas engine.
Flyers will use NGH gas engine well if he has experience with glow engine ever.

You can use same rate for fuel and oil mixture with 30:1 or 35:1. no problem.

I suggest you fly your GT35 first and later you can try to convert it to GT35R.

thank you sir.
