Popular Post Jumper Posted July 24, 2020 Popular Post Share Posted July 24, 2020 (edited) We have a decent Hyper MTE thread, thought i'd do a thread for the nitro version. It doesnt seem to get much attention and i have found it hard to find information on it. Probably because nobody buys them. Anyway, i have bought one, as it have wanted a Hyper MT 2 Plus, but i also wanted a full size nitro truck again. I've had the truck over a month now and its been both terrible and great. Firstly, i decided to get an LRP ZR.28 Spec4 engine for it. I'm not really sure why as its not much better than the stock engine, but i really liked the cooling head XD The ZR.32 was not in stock with a pullstart anywhere when i got it and if i was to buy it again i would go with the .32. It comes with the turbo .30 engine and tbh if you like the look of it, i would leave that in as you will see. I wont go over the chassis much as i they its covered well in the MTE thread. I will say that mine came with 5mm universals on all 4 corners. The tank is mounted on the opposite side to a savage. The throttle servo also hangs off the same side of the tank which makes the throttle and brake linkage easier to set up than a savage. The brake is a single steel disc unlike the savage twin fibre glass disks. It seems to work fine though. The pipe and header are much nicer than a savage. No silicone coupler. The standard clutch is 3 plastic shoe clutch which paired with the 7 inch tyres and the 14T bell doesn't really perform too well. The main issue i had putting the LRP engine in was the pullstart and backplate. The pullstart on the LRP is much larger. The engine would sit flat so i had to make some 3mm spacers. You can see the Hobao Pullstart system is very small and compact. The next problem you have when you raise the engine is the exhaust hanger isn't at the right height any more. During the engine break in i just tied the exhaust to the chassis with garden wire. I have made a custom hanger from an m3 screw through a hole thats standard on the chassis, but not used, a 3mm steel tube and a long bolt. Then i have bent a 3mm metal coat hanger to shape to hold it in the right place. So far its held up really well. Another issue was the exhaust gasket which came on the LRP engine was too small, and although it ran ok for the engine break in, it leaked really badly when i was trying to tune the truck. I swapped the gasket over from the Hobao engine and it was fixed. As you can see most of the issues i've had to troubleshoot on this truck are because i decided to get an aftermarket engine. I also got a few other options right out the box: Reverse kit Replaced the steering servo with a JX Ecoboost CLS3627 HV hardened steel spur Wheelie bar Front chassis brace I also built the diffs up with 30K oil as they are grease filled as standard. The reverse kit involves putting some extra gears in the gearbox and replacing the bottom shaft. I didnt really take any pics of me doing it because i had no idea if i was doing it right. The instruction are ok, but the linkage setup is not really detailed very well. You end up with an extra servo which fits in the radio box underneath. Its a bit of a pain to setup, but once you have it set up on the radio and the linkage you can have forwards with 2 speed and neutral and reverse. I have this set up to the 3 position switch on my Flysky GT5, it wasnt the easiest thing to setup, but it works ok now. The two speed did need adjusting out the box to shift a bit earlier as the engine was really screaming for a few seconds before it would shift and on grass or slight uphill it wouldnt shift at all. Its easy enough to tune the 2nd gear. Same as a savage, you just lift the rubber grommet and turn the screw on the 2nd gear clutch out a little bit to make it shift sooner. Pretty much as soon as i finished the break in i swapped out the clutch for a red racing 4 shoe. Its a really really nice clutch, almost a shame its hidden under the bell. It bites really hard. Since then i have mostly been doing tuning to the engine to try and get it to run well. I have cut out some holes in the windows to give it some airflow and i have almost got it running where i want it. It still runs a bit rich and i managed to get a speed run with the sky rc gps at 34MPH. I think it will be able to go about 40 once i have it full dialed in. I also have had a issue with the driveshafts. The pins in the universal joint keep coming out and when they get so far they hit the inside of the hub and snap. I have had this happen twice where it snapped and once i have managed to catch it half way out. Here is a new shaft vs one where the pin was starting to come lose. I have sent the shop detailed pictures of the issue to send to hobao, so hopefully they can fix it. I did buy a pair of new shafts myself and the new ones have been ok so far. Only the shafts that came on my truck have had this issue. 2 have snapped completely and one was poking out after i checked after running. Once this issue has been fixed, i hope it will be a solid truck. I have put about 5L of fuel through the engine now, so i've had one proper session at the skate park with it, which was end with the drive pin falling out rather than a breakage. I also picked up a MTE spares truck locally too, so when it does break i'm covered. It also came with a different body too.

Jumper Posted August 8, 2020 Author Share Posted August 8, 2020 So i ordered 2 pairs of brand new drive shafts. All 4 of them are cracked straight out the packet checked the shafts i was using in the truck and another one had snapped, 2 are cracked and 1 is ok. I have 10 of the drive shafts now and only 1 of them isn't cracked or broken Last run i didnt even jump the truck at all. I spent 4 tanks just refining the tune on the engine and still manage to snap a pin. Quote Link to comment Share on other sites More sharing options...

Clearly some kind of quality control issue, which is strange because hyper St and mt2+ use the exact same universal shaft design and they hold up perfectly fine. The rest of the truck has been solid as well. Not broken anything other than drive shafts so far. Quote Link to comment Share on other sites More sharing options...

Have you tried adjusting the shift point? Quote Link to comment Share on other sites More sharing options...
